What this does: the Rust SDK can now send and find DashPay private contact requests.
To send, it appends a sealed entry to a private document type's store, paid from the shielded pool (transition type 29).
To find, it reads a page of that store and sorts its entries with a wallet's keys into three groups:
entries addressed to one of the wallet's identities;
entries the wallet sent, recovered after a restore from seed;
entries that open but are refused.
On top of that sit DashPay helpers: a typed PrivateContactRequest, sealing one, and a reader that checks each request against its sender's and recipient's keys.
A private request is signed by one of the sender's signing keys, as a public request's transition is, with the same identity signer. The signature sits inside the encrypted entry: only the recipient sees it.
Value: this is the client half of anonymous DashPay contact requests (protocol version 15). Until now the chain could store private entries (#5799, #5804) and the envelope could seal and open them (#5806), but nothing in the SDK sent the transition or walked the store. Wallets, wasm-sdk and the mobile SDKs build on these calls.
Risks: low. It is client code only, with no consensus change. It also changes the envelope's signature mode in platform-encryption (#5806). Nothing uses that mode yet and nothing is deployed, so the change breaks nothing.
Issue being fixed or feature implemented
Part of anonymous DashPay contact requests for 5.1. Sam's decisions, all applied here:
the outgoing viewing key is derived from the sender identity's DashPay encryption key, H("Dash/PrivDoc/v1/ovk" || encryption secret key), with no new derivation path;
the request is signed by the sender's signing key, rather than carrying a deniable MAC. So the recipient's own key cannot produce a request from someone else, just as it cannot produce a public one. The trade-off: the recipient could prove to a third party who wrote it. Nobody else can see the signature;
a recipient keeps the first request per sender and account reference (there is no chain uniqueness);
PrivateDocumentCreateFromShieldedPool is a trait on Sdk. It builds the type 29 transition from a proven bundle with try_from_bundle, structure-checks it, then broadcasts it and waits for the proof that its nullifiers were spent. It mirrors IdentityTopUpFromShieldedPool. The bundle comes from the dpp builder, as for the other shielded spends.
sdk.private_document_create_from_shielded_pool(dashpay_id, "privateContactRequest",
vec![entry], fee, bundle, None)
before: no SDK call; a wallet had to assemble and broadcast type 29 by hand
after: Ok(StateTransitionProofResult::VerifiedShieldedNullifiers(..))
with no entries, or two the same: refused before broadcasting, as consensus would refuse it
Scanning (platform::private_document_scan)
PrivateDocumentScanKeys prepares a wallet's keys once:
with_recipient(identity, &[(key_id, secret_key)]) adds an identity's keys that entries may be sealed to;
with_sender(identity, key_id, outgoing_viewing_key) adds the key an identity seals its own entries with, and the id of the key it is derived from.
scan_page(target, start, page) sorts a page into received, sent and rejected entries, and returns the position to scan from next:
an entry opened under a key but naming another identity is a replay, and is rejected only if no other identity of the wallet opens it;
an entry refused on both sides is listed once.
verify_sender checks a deniable MAC with the key that opened the entry, trying each key set the identity was added with.
Sdk::scan_private_document_page fetches the proved page and sorts it.
page of 5 entries from position 10, wallet holds Alice (keys 2, 3, outgoing key of key 1) and Bob (key 1)
10: to Alice's key 3 -> received (Alice, key 3)
11: to someone else -> passed over
12: Alice to Dave -> sent (Alice, key 1)
13: Bob's key, names Dave -> rejected: WrongRecipient
14: Alice to Bob -> received (Bob, key 1) and sent (Alice, key 1)
next_position: 15
to_properties and from_properties check the schema's bounds. The SDK's dpp features have no JSON schema validation. A test pins the bounds to the ones dpp parses from DashPay v3.
Sending is three steps, so the signature can come from an identity signer:
private_contact_request_signing_data(contract, sender, encryption_key_id, recipient, recipient_key_id, request) is what the sender signs;
private_contact_request_signature(signer, signing_key, &data) signs it with any Signer<IdentityPublicKey>;
seal_private_contact_request(contract, sender, recipient, recipient_key_id, request, esk_seed) builds the entry. sender names the encryption key and its secret key (for the outgoing viewing key), and the signing key and its signature.
The seal checks every key:
the named key must be the sender's enabled ECDSA_SECP256K1ENCRYPTION key, and its secret must match. The pair's shared key is derived from it;
the signing key must be an enabled AUTHENTICATION key at a level the type's documents are signed at (CRITICAL or HIGH, from the type's requirement, as Drive computes it), ECDSA_SECP256K1 or ECDSA_HASH160, and bound to no other contract or document type (DashPay, or its privateContactRequest type; a contract group bound signs none, as a client cannot read the group's members as they were). The signature must be its own. private_contact_request_signing_keys(contract, identity) lists the keys that qualify;
the recipient key must be an enabled ECDSA_SECP256K1DECRYPTION or ENCRYPTION key, the same rule as public requests.
Sdk::seal_private_contact_request does all three with the bundled DashPay contract, the first signing key the signer holds, and a fresh seed.
private_contact_requests_from_scan(contract, scan, identities, platform_version) reads a scan. identities holds the identities private_contact_request_identities(&scan) lists. Each entry is checked before its payload is decoded:
it must be signed, and its sender must exist;
the encryption key it names must be the sender's, enabled when the entry was appended;
a key of the sender that may sign the type's documents, enabled then, must have signed it. The key is recovered from the signature;
a received entry's recipient key must have been enabled then too;
a sent entry must name the identity and key its outgoing viewing key comes from.
The first request per recipient, sender and account reference is kept.
Sdk::scan_private_contact_requests fetches the page and each listed identity once, then reads it.
received entry naming sender S and encryption key 1
S does not exist -> rejected: SenderNotFound
carries a deniable MAC -> rejected: NotSigned
S's key 1 is not an enabled ENCRYPTION key then -> rejected: SenderKeyNotUsable
signed by S's HIGH signing key, enabled then -> received
signed by S's key disabled before the entry, or at MEDIUM or MASTER -> rejected: SenderKeyNotUsable
signed by a key S does not hold (the recipient's, say) -> rejected: SenderNotAuthenticated
the recipient key was disabled before the entry -> rejected: RecipientKeyNotUsable
no sender (anonymous) -> rejected: AnonymousSender
second request from S, same accountReference -> rejected: Duplicate (the first is kept)
sent entry recovered with S's outgoing viewing key of key 1
names key 3, or another identity, or no key of S signed it -> rejected: SenderNotAuthenticated
platform-encryption (envelope signature mode)
A signature now signs the double SHA-256 of the signing data m. That is how a Dash identity signer signs data, so a wallet signs with the signer it signs transitions with. m is a 32-byte hash, which no transition's signable bytes can be.
PrivateDocumentSender::Signature takes the signature instead of a secret key. The seal refuses bytes that are not a signature. New functions:
private_document_signing_data
sign_private_document_signing_data
recover_private_document_signer
OpenedPrivateDocumentEntry::recover_signer
The key id an entry names may be another key than the signer: DashPay names the encryption key, and the signer is recovered.
The authenticated data m now names the recipient key ser(R), in every mode, so a body re-encrypted to another key of the same identity authenticates no sender. private_document_signing_data takes the recipient. The MAC and signature vectors are re-pinned.
PrivateDocumentRecipientKeys wipes its secret keys on drop. PrivateDocumentEnvelopeError is now Clone, with a new NotSigned.
signature mode, signing data m
before: auth = ECDSA(m) by the named key, signed with a secret key handed to the seal
after: auth = ECDSA(SHA-256(SHA-256(m))), the signature Signer::sign(key, m) returns;
the signer is recovered from it
Changes from review
Validation in DPP. Requests are checked against their type's schema with dpp's DataContract::validate_document_properties, before encoding when sealing and after decoding when reading, as the payload codec asks. The SDK's own bound checks are gone, and the SDK now enables dpp's validation feature.
Side effect: contract parsing with full validation requested now actually validates in every SDK built on rs-sdk. For example, wasm-sdk's DataContract.fromJSON validates by default. Two fixes came with it:
A wasm-sdk fixture with an indexed string lacking maxLength was fixed.
wasm-dpp2's DataContract constructor parsed document types before adding the contract's tokens, which refused a document paying in the contract's own token. It now parses them with the tokens.
Identities proved after their entries. The reader takes ProvedIdentity { identity, proved_at_height }. A snapshot proved before the latest block whose entry it checks, a missing identity, or one given under another id fails the read instead of judging the entry. Sdk::fetch_private_contact_request_identities fetches them four at a time and refetches a stale one once.
Protocol 15 first. The DashPay helpers and private_document_create_from_shielded_pool establish protocol version 15 before resolving DashPay or building the transition. A DashPay the context provider holds from before the private type is refetched and registered with the provider. A DashPay fetched from the network because the provider held none is registered the same way. If the provider still gives the old one afterwards, or none, the helper fails at once instead of failing every page's proof.
Contract bounds of encryption keys. dpp now owns the scope decision: ContractBounds::check_document_type answers Allowed, Denied, or "needs the contract group's members", which only state can answer. The SDK's existing encrypted_for key check, the signing key check and both encryption keys of a private request use it. A group bound is refused.
The sender's and recipient's encryption keys may be unbound, bound to DashPay, or bound to DashPay's contactRequest or privateContactRequest. contactRequest is allowed because DashPay requires bound encryption and decryption keys for it, and apps register their DashPay keys bound to that type. Keys bound to another contract, another DashPay type or a group are refused, in the seal and in the reader.
Stricter key checks.
Signing keys bound to another contract or to a contract group are refused.
Signing keys past expires_at are refused, at the entry's block time in the reader and at the device's clock when sealing.
A received entry's recipient key must be the key it is encrypted to.
A scan of another store is refused. An opened entry keeps the store it was opened for (contract_id, document_type_name), and private_contact_requests_from_scan refuses a scan holding an entry of any store but DashPay's privateContactRequest.
The reader's docs say what is not established: keys are those of the proved identity, which may be newer than the entry, and Platform records when a key was disabled, not when it was added.
The authenticated data names the recipient key, so an entry re-encrypted to another key of the identity authenticates no sender.
Smaller changes.
Recovered sent requests are deduplicated.
Senders sharing an outgoing viewing key are attributed by the key the entry names.
PrivateDocumentScanKeys::derive builds scan keys from key paths.
An OS RNG failure is an error, not a panic.
seal_private_contact_request(contract, sender, recipient, key_id, request, esk_seed)

a second recovered sent request for the same account reference is a duplicate;
an unknown property set to null is refused;
a scan of another contract's store with DashPay's types is refused, received and sent;
an account label over 63 bytes is refused even at 32 characters.
private_document_scan: senders sharing an outgoing viewing key recover an entry as the one it names.
transition: entries consensus refuses are refused before broadcasting; an unpinned SDK seeded at 14 learns the network's version before it builds the send, and builds it at that version.
dpp (cargo test -p dpp --lib contract_bounds): the document-type scope of single-contract, document-type and contract-group bounds.
platform-encryption (cargo test -p platform-encryption private_document, 13 tests): signer recovery, signatures of other data, non-signatures refused at seal, and the re-pinned signature-mode hash.
The DashPay refresh is tested with a test context provider; reading a full page is tested through the pure private_contact_requests_from_scan.
In-place changes to shipped generations
DocumentsBatchTransitionMethodsV0::combined_security_level_requirement (batch transition methods v0, every protocol version that authorizes document batches) now returns SecurityLevel::document_signing_levels() of its strongest requirement instead of computing the range inline. Consensus cannot change: the new helper returns, for every SecurityLevel, exactly the vector the old code built, namely [MASTER] for MASTER and CRITICAL..=requirement in the same order otherwise. The only other difference is that the unwrap in the old range conversion is gone. dpp tests pin the outputs for each of the four requirements, a mixed batch, a token batch and an empty batch.
Breaking Changes
None for consensus. dpp gains ContractBounds::check_document_type and DocumentTypeBoundsCheck, a pure client-side helper that consensus does not call. The new SDK functions changed their signatures during review (see above); none had shipped. In platform-encryption, PrivateDocumentSender::Signature takes a signature instead of a secret key, the signature signs the double SHA-256 of the signing data, and the authenticated data of every mode names the recipient key. Nothing used these modes yet.

Summary by CodeRabbit
New Features
Added support for scanning private document stores, including received, sent, and rejected entries, with page-by-page retrieval.
Added private document signing and sender verification, plus APIs for creating private documents from shielded pools.
Added private contact request APIs and document-type checks for contract key bounds.
Added support for token configurations on compatible contract versions.
Bug Fixes
Private document operations now respect protocol version requirements and handle stale store pages.
Cached contracts are preserved when a newer version is already held.
Batch document signing levels now reflect the strongest applicable requirement.
The prepared-keys test also opens an entry with the first key of the
set, so a scan skipping earlier keys would fail it.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The SDK can now append entries to a private document type's store, paid
from the shielded pool (type 29), and find a wallet's entries in it:
- `PrivateDocumentCreateFromShieldedPool` builds, structure-checks and
broadcasts the transition from a proven bundle, and waits for its
nullifiers to be proven spent.
- `PrivateDocumentScanKeys` and `Sdk::scan_private_document_page` sort a
proved page of a store into what the wallet's identities received
(their keys open it), what they sent (their outgoing viewing keys
recover it) and what opened but is refused, with the cursor to scan
from next.
- DashPay: `PrivateContactRequest` with the schema's bounds,
`seal_private_contact_request` (the sender's encryption key, a deniable
MAC, and the outgoing viewing key derived from that key), and
`Sdk::scan_private_contact_requests`, which decodes each request,
checks its sender against the identity key it names and keeps the
first request per sender, recipient and account reference.
platform-encryption: prepared recipient keys check a sender with the key
that opened the entry, so a scan never copies secret keys out.

A wallet restoring its sent requests needs the encryption key each was
sealed with to rebuild its local record of the request.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A private contact request carried a deniable MAC keyed by the static ECDH
of the sender's encryption key and the recipient's key. Anyone holding the
recipient's key could compute it, so a stolen recipient key forged requests
from any sender, including rotations that redirect the recipient's payments.
The request is now signed by one of the sender's signing keys, as its public
request's transition is: an enabled AUTHENTICATION key at a level DashPay's
documents are signed at (CRITICAL or HIGH), ECDSA_SECP256K1 or ECDSA_HASH160.
The entry still names the encryption key, which the pair's shared key and the
outgoing viewing key come from; the reader recovers the signing key from the
signature. Entries with a MAC are refused.
Envelope (signature mode, nothing deployed): the signature now signs the
double SHA-256 of the signing data, as identity signers sign data, so a
wallet signs with the signer it signs transitions with. The caller passes
the signature; `private_document_signing_data`,
`sign_private_document_signing_data`, `recover_private_document_signer` and
`OpenedPrivateDocumentEntry::recover_signer` are new. Prepared recipient keys
are wiped on drop.
Reading also checks, at the entry's block time, the recipient key it is
encrypted to, and that a sent entry names the identity and key its outgoing
viewing key comes from and is signed by that identity. The sender is checked
before the payload is decoded. `PrivateDocumentScanKeys::verify_sender`
tries every key set of the identity.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Signature-mode entries use caller-supplied recoverable signatures over authentication data that includes the recipient public key. Opened entries expose signer recovery and sender verification. Prepared recipient keys can verify deniable MACs using the key that opened an entry.
The SDK checks whether a held or fetched contract declares the requested private document type.
Carry proved store chunk geometry packages/rs-drive/src/drive/document/private_document_store/*, packages/rs-drive/src/verify/document/verify_private_document_entries/v0/mod.rs, packages/rs-drive-proof-verifier/src/types/private_document_entries.rs, packages/rs-sdk/src/mock/requests.rs, packages/rs-sdk/src/error.rs
Private-document pages carry optional chunk power. Drive reads and verified pages set it; unproved responses set it to None. SDK mocks serialize the field, and the SDK adds a stale-node error for pages behind an earlier snapshot.
Register keys and classify entries packages/rs-sdk/src/platform.rs, packages/rs-sdk/src/platform/private_document_scan.rs
The SDK adds scan-key registration and derivation, then classifies entries as received, sent, or rejected. Scan results retain store metadata and a next-position cursor.
Fetch and scan pages packages/rs-sdk/src/platform/private_document_scan.rs
The SDK adds ordered page streaming with sequential discovery and bounded concurrent fetches. It handles older snapshots, retries empty pages from behind nodes, and validates chunk geometry.
Shielded-Pool Private-Document Transition
Layer / File(s)
Summary
Check the network protocol version packages/rs-sdk/src/sdk.rs, packages/rs-sdk/src/sdk/protocol_gate.rs, packages/rs-sdk/src/sdk/protocol_gate_tests.rs
The SDK adds protocol-version refresh and probing helpers. Tests cover probe results and refusal to send when the network is below protocol version 15.
Build and submit the transition packages/rs-sdk/src/platform/transition.rs, packages/rs-sdk/src/platform/transition/broadcast.rs, packages/rs-sdk/src/platform/transition/private_document_create_from_shielded_pool.rs
The SDK exposes transition-building and submission methods. The builder checks protocol version and transition structure. Submission checks network support, broadcasts the transition, and waits for the affected-state proof result.
Version-Aware Contract Cache Updates
Layer / File(s)
Summary
Preserve newer held contracts packages/rs-context-provider/src/provider.rs, packages/rs-sdk-trusted-context-provider/src/*, packages/rs-sdk/src/mock/provider.rs, packages/wasm-sdk/src/context_provider.rs, packages/wasm-sdk/src/sdk.rs
Context providers and SDK caches retain a held contract when its version is higher than an incoming contract. Explicit replacement methods can replace the held contract regardless of version.
DashPay Private Contact Requests
Layer / File(s)
Summary
Validate and expose contact-request APIs packages/rs-sdk/Cargo.toml, packages/rs-sdk/src/platform/dashpay/contact_request.rs, packages/rs-sdk/src/platform/dashpay/mod.rs
The SDK enables DPP validation, exposes the sender key-purpose check to crate-level callers, and declares and re-exports private contact-request APIs.
Document-Type Bounds Checks
Layer / File(s)
Summary
Define and apply document-type bounds packages/rs-dpp/src/identity/identity_public_key/contract_bounds/mod.rs, packages/rs-sdk/src/platform/encrypted_for.rs
The bounds check distinguishes allowed, denied, and contract-group membership-required results. The SDK uses it when evaluating key scope. Tests cover matching and mismatching bounds.
Batch Document Signing Levels
Layer / File(s)
Summary
Map requirements to signing levels packages/rs-dpp/src/identity/identity_public_key/security_level.rs, packages/rs-dpp/src/state_transition/state_transitions/document/batch_transition/*
SecurityLevel::document_signing_levels returns the levels for a requirement. Batch transition logic delegates to it, with tests covering individual and combined requirements.
WASM Data-Contract Token Configuration
Layer / File(s)
Summary
Include tokens in contract parsing packages/wasm-dpp2/src/data_contract/model.rs, packages/wasm-dpp2/tests/unit/TokenConfiguration.spec.ts
The constructor serializes and inserts nonempty tokens, and rejects tokens when contract structure version 0 is selected. The setter rejects nonempty tokens for that structure version. Tests cover token positions and version handling.
Card-Game Fixture Schema
Layer / File(s)
Summary
Set the rarity string limit packages/wasm-sdk/tests/unit/fixtures/data-contract-v0-crypto-card-game.ts
The fixture schema sets the rarity property’s maximum string length to 63 characters.

values for recognized property names; preserve unknown null-valued properties
until the unknown-property check rejects them.
- Around line 521-524: Update the key-validity check in the scan around the
disabled_at match arm so it distinguishes operation order when an append and key
disable share a timestamp. Accept requests appended before the disable, but
reject requests appended after it; do not treat all equal timestamps as valid,
and preserve the scan cursor for valid requests.
- Around line 1022-1023: Update the identity-resolution flow in the private scan
so it does not call Identity::fetch sequentially for IDs returned by
private_contact_request_identities. Reuse identity data obtained independently
of the scan or an established privacy-preserving lookup mechanism, while
preserving the scan’s existing identity results and error handling; establish
which safe mechanism is available before changing the lookup path.
- Line 558: Update signing-key validation in the sealing and reading paths
around disabled_problem(key, "signing", at_ms) to enforce the key’s contract and
document-type bounds against DashPay’s privateContactRequest type, and verify
contract-group membership at the entry’s block time. Preserve existing signing
checks while ensuring both paths reject keys whose bounds do not authorize this
request.
- Around line 803-805: Deduplicate recovered outgoing requests in the scan.sent
loop using a separate set keyed by sender, recipient, and account reference;
append only the first valid request for each key to result.sent. Keep this set
independent of received-request deduplication so a request present in both sent
and received results is preserved.
- Around line 913-917: Update the reader’s signing-key validation loop around
`sender.public_keys()` and `signing_key_problem` to verify that the matching key
was registered by the entry’s append time before accepting the request. Use the

disabled-key, and signing-level checks; do not rely solely on the identity’s
current key set.

Review fixes:
- The envelope's authenticated data names the recipient key `ser(R)`, so
a body re-encrypted to another key of the same identity (an old key's
holder re-targeting a signed request) authenticates no sender.
`private_document_signing_data` takes the recipient. The MAC and
signature vectors are re-pinned; nothing is deployed.
- A signing key bound to a contract signs only inside its bounds:
DashPay, or its `privateContactRequest` type. A contract group bound
signs none, as a client cannot read the group's members as they were.
The seal and the reader apply the same rule;
`private_contact_request_signing_keys` lists the keys that qualify.
- `PrivateContactRequest::from_properties` drops a null only under an
optional property's name, so an unknown property set to null is refused.
- Recovered sent requests are deduplicated per sender, recipient and
account reference, apart from the received ones.
- Senders added with the same outgoing viewing key: an entry recovers as
the one it names.
- Docs: the transition's proof shows the nullifiers spent, not that its
entries were appended; fetching a sender right after its page tells the
serving node which identity the wallet looked up.

The private send picks the first signing key the signer holds among
`private_contact_request_signing_keys`, which adds the contract bounds rule
of #5809 to the level and type rules: a key bound to another contract or
document type, or to a contract group, is never chosen, as the seal would
refuse it.

Final validation — Phase 1 + Phase 2
Verified head 3d510b8 and confirmed three blockers: stale identity snapshots can bypass revocation checks, contract resolution precedes protocol discovery, and payload validation duplicates DPP-owned rules. The identity-fetch performance findings are combined into one suggestion. This was static review only; current CI reports passing Rust workspace, wasm32, JavaScript, Swift, and Kotlin checks, with PR Hygiene and the automated review pending.
Triage: critical by gpt-6.1-sol (effort low) — The large, intricate diff changes cryptographic signature handling in packages/rs-platform-encryption/src/private_document_envelope.rs and implements signing, key derivation, and verification in packages/rs-sdk/src/platform/dashpay/private_contact_request.rs.
These findings are from an automated code review. Verify each finding against the current code and only fix it if needed.
In `packages/rs-sdk/src/platform/dashpay/private_contact_request.rs`:
- [BLOCKING] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:1097-1101: Require identity snapshots to cover the entries they authorize
Identity::fetch discards the verified response metadata, so this composition never establishes that an identity snapshot includes the block that appended its request. Fetching after the page is insufficient: SdkBuilder defaults to metadata_height_tolerance: Some(1), and get_identity uses that tolerance. After accepting a page at height H, the SDK can therefore accept an identity proof from H-1. If a compromised signing key is disabled in block H and an attacker appends a request in that same block, a malicious DAPI endpoint can return the genuine page from H alongside a saved identity proof from H-1. The reader then sees no disabled_at and authenticates the request, bypassing its rejection of keys disabled at or before the append time without either proof being forged. Fetch identities with verified metadata and require each snapshot to cover at least the maximum append height of the entries whose authorization depends on it; retry or fail when the snapshot is older. Add coverage for a page at H and an identity snapshot at H-1 containing the formerly enabled key.
- [BLOCKING] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:1026-1027: Discover protocol 15 before resolving the DashPay contract
A fresh unpinned SDK starts at protocol 13, or 14 on devnet. fetch_dashpay_contract first consults the context provider, and the bundled providers load DashPay using that current SDK version without contacting the network. This returns DashPay v1/v2, so private_contact_request_signing_keys fails because privateContactRequest is absent even when the network runs protocol 15; repeating the seal does not discover the newer version. scan_private_contact_requests has the same ordering problem at line 1088: its subsequent page fetch can discover protocol 15, but the final reader still receives the previously captured old contract. Require the feature's initial protocol version before resolving the contract in both helpers, following fetch_moderation_charters_contract's require_protocol_version pattern. Cover an initially unpinned SDK with a bundled context provider.
- [BLOCKING] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:189-202: Delegate payload schema validation to DPP
check_bounds independently enforces accountLabel.maxBytes and autoAcceptProof.minItems/maxItems using SDK constants. These checks already belong to DPP's document-property validation, and the book's “Validation lives once” rule explicitly prohibits SDK copies of DPP length, range, and count checks. Both sealing and reading use this duplicate validator even though their codec receives a DataContract; the codec explicitly leaves schema-bound validation to DataContract::validate_document_properties. Pinning today's bundled schema in a test does not make runtime validation follow the supplied contract. Keep typed conversion in the SDK, but validate before encoding and after decoding through DPP-owned machinery. Enable the canonical validation entrypoint or expose a client-appropriate entrypoint in DPP backed by its existing native validation-schema implementation rather than maintaining another definition of valid payloads.
- [SUGGESTION] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:759-769: Prune identity dependencies and overlap independent fetches
This collector includes identities from anonymous and deniable-MAC entries, although EntryReader::check_sender rejects both modes before accessing any identity. The convenience scan then fetches every collected identity sequentially, including sender IDs supplied by entries it will reject. Such a page creates unnecessary proof-verified requests, an unrelated lookup failure can fail the entire scan, and N required identities incur N sequential round trips. Filter non-signature entries from both received and sent dependency collection, preserving their existing rejection results, then resolve the remaining independent identities with bounded concurrency. The SDK already uses buffered query concurrency elsewhere.
Your move: thepastaclaw requested changes on this head; dismiss the review or push a fix; thepastaclaw left review threads unresolved; resolve them.
Full checklist in the description.
…y heights
Review fixes:
- Requests are checked against their type's schema with dpp's document
validation (`DataContract::validate_document_properties`), before
encoding when sealing and after decoding when reading, as the payload
codec asks. The SDK's own copies of the label and proof bounds are gone;
`to_properties` is a typed conversion. The SDK enables dpp's `validation`
feature. `seal_private_contact_request` and
`private_contact_request_signing_data` take `platform_version` last.
- The reader takes each identity with the height its proof is of
(`ProvedIdentity`). `private_contact_request_identities` lists, per
identity, the latest block whose entry it checks; a snapshot proved
before it, which a node may serve within the SDK's height tolerance, or
one not given, fails the read instead of judging the entry against keys
as they were before it. Only signed entries need identities.
- `Sdk::fetch_private_contact_request_identities` fetches them four at a
time with their metadata and fetches a stale one once more.
- Both SDK helpers establish protocol version 15 before resolving DashPay,
so an unpinned SDK starting below it does not read a DashPay without the
private type.
- `PrivateDocumentScanKeys::derive` builds scan keys from key paths with a
derivation callback, wiping what it derives, for signers that keep keys.

Review fixes (with the SDK changes of #5809 merged in):
- A private request whose store fails after it was paid for is kept in
memory (`add_paid_sent_contact_request`): the contact it answers
establishes, so a retried accept adopts it instead of paying for another
reply, and the next add of the same request (the private sync recovers it
from the store) stores it. Before, the failed store left no request and no
contact, so the accept failed and a retry paid again.
- `PlatformWallet::accept_contact_request_replying_in_kind` takes what a
private reply is paid with as `payment`, a closure called only for a
private reply (`PrivateReplyPayment`: coordinator, seed, account, prover).
A public reply or an adopted one needs neither shielded support nor the
seed.
- The private sync checks each page against identities proved at or after
its entries (`ProvedIdentity`), fetching a few at a time only those it
lacks or holds from an older proof.
- Scan keys are built with the SDK's `PrivateDocumentScanKeys::derive`; the
crypto provider's seal takes `platform_version`, which the SDK's schema
validation needs.

Review fixes (with the SDK changes of #5809 merged in, which also resolve
DashPay only once protocol version 15 is established):
- `getPrivateDocumentEntries` loads the contract (`get_or_fetch_contract`)
before fetching a page, as the page's proof is checked against it and
the context provider holds a custom contract only once loaded.
- Secret keys read from the options are held in a guard that wipes them
when dropped, so an error parsing a later option wipes them too. The
seal reads the encryption key after every other option.
- The scan's docs, and the evo-sdk facade's, say it fetches the identities
the page's requests are checked against right after the page, which a
node serving both can correlate.
- The shared `secret_key_from_options` and `try_to_fixed_bytes` replace
the local helpers.

Re-review — Final validation — Phase 1 + Phase 2
Verified head d4efa2e: all four prior findings are fixed, but blocking issues remain in standalone protocol discovery, signing-key expiry enforcement, and CI compatibility after enabling DPP validation. Current CI confirms 15 WASM contract-fixture test failures caused by the newly activated validation; Rust workspace tests remain pending, while the JS build, wasm32, Kotlin, and Swift schema checks passed. This was a static review; no local builds or tests were run.

- [BLOCKING] packages/rs-sdk/src/platform/transition/private_document_create_from_shielded_pool.rs:95-101: Discover protocol 15 before building standalone private submissions
This independent async sending API invokes the synchronous builder before discovering the network protocol version. A fresh unpinned SDK starts at protocol 13, or 14 on devnet; the builder then structure-checks against historical SystemLimits where max_private_document_entries_per_transition is None. DPP interprets that limit as zero and rejects every nonempty batch with InvalidPrivateDocumentEntryCountError before any network request can update the SDK. Consequently, already sealed entries and proven bundles prepared offline or restored for retry cannot be submitted even to a protocol-15 network, and repeating the call cannot recover. The gate in the DashPay seal/scan helpers does not cover this route. Await require_protocol_version with PRIVATE_DOCUMENT_CREATE_FROM_SHIELDED_POOL_INITIAL_PROTOCOL_VERSION before invoking the builder. Preserve the synchronous builder's explicit-version behavior and DPP's historical rejection, and add coverage for direct submission from an initially older unpinned SDK.
In `packages/rs-sdk/src/platform/dashpay/private_contact_request.rs`:
- [BLOCKING] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:599-600: Reject signing keys expired at the request's append time
Signing-key eligibility ends with disabled_problem, which checks only disabled_at. IdentityPublicKey::V1 also carries expires_at, and DPP defines the expiry instant itself as expired through IdentityPublicKeyGettersV1::is_expired_at. A HIGH AUTHENTICATION key with disabled_at = None and expires_at = T therefore remains eligible here for an entry appended at or after T. EntryReader::check_sender accepts its recovered signature, and private_contact_request_signing_keys continues offering it, although the public transition path rejects an expired key with PublicKeyExpiredError. A holder of an expired delegated key can thus continue producing authenticated private requests. Reuse DPP's expiry predicate with the entry's authenticated block_time_ms, and give selection/sealing an explicit time context so they enforce the same policy. Cover V1 keys immediately before, at, and after expiry while preserving requests appended before expiry.
- [SUGGESTION] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:1159-1166: Exercise the metadata-aware identity resolver in regression tests
The new height regression constructs ProvedIdentity values directly and exercises private_contact_requests_from_scan, but no test invokes fetch_private_contact_request_identities. It therefore does not cover preservation of verified response metadata, retrying a stale first response, or the distinction between a fetch failure and a proved absent identity. Add deterministic resolver-level tests for H-1 followed by H, two responses at H-1, a fetch error, and a sufficiently recent proved None. Assert that stale responses never produce a usable identity map and that a successful retry preserves the second response's identity and height. A small injectable fetch helper or metadata-capable mock can exercise the actual async control flow without network calls.
- [SUGGESTION] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:1114-1115: Return an error when OS entropy cannot seed the RNG
StdRng::from_os_rng explicitly panics when getrandom cannot provide entropy. That environmental failure bypasses this Result-returning sealing API and can terminate its host rather than returning a seal error. Use try_from_os_rng and propagate the failure through Error; this preserves secure failure without introducing an insecure fallback.

Enabling dpp/validation here also enables it in wasm-sdk's shared DPP dependency, activating checks that DataContract.fromJSON(..., true, ...) previously skipped. The existing V0 crypto-card fixture indexes rarity but gives that string no maxLength; DPP's generation-0 index validation requires an indexed string to have maxLength <= 63. The current 'JS packages (Evo SDK packages) / Tests' check fails in job 128769208640 with 15 WASM tests reporting "Indexed property 'rarity' for 'card' document has an invalid constraint 'maxLength', reason: 'should be less or equal 63'" at 15:06:12, followed by '@dashevo/wasm-sdk exited with 15'. Update packages/wasm-sdk/tests/unit/fixtures/data-contract-v0-crypto-card-game.ts to satisfy canonical validation, including the missing rarity bound, and keep the full-validation tests enabled.

Re-review — Final validation — Phase 1 + Phase 2
At f7fcc44, all 22 prior findings are addressed, but recipient-key attribution can still discard a valid request and advance the scan cursor past it. Two non-blocking improvements remain around stale-page retry classification and exposing authenticated page geometry; the WASM token guards fit the documented information-preserving conversion exception. Validation was static-only: current CI shows JS builds, wasm32 tests, Kotlin tests, and Docker builds passing, with Rust workspace tests and several JS/integration suites pending and no failed code checks reported.
Triage: critical by gpt-6.1-sol (effort low) — The large, intricate diff directly changes cryptographic signature handling in packages/rs-platform-encryption/src/private_document_envelope.rs and adds encrypted request signing, key handling, and shielded-funded sending in the SDK.
These findings are from an automated code review. Verify each finding against the current code and only fix it if needed.
In `packages/rs-sdk/src/platform/private_document_scan.rs`:
- [BLOCKING] packages/rs-sdk/src/platform/private_document_scan.rs:326-330: Preserve recipient-key aliases until their eligibility is checked
The scanner attributes an opened entry exclusively to the first decrypting key's index, before the DashPay reader checks that record's eligibility. A recipient can hold a disabled compressed ECDSA key under ID 1 and an enabled uncompressed encoding of the same point under ID 2: DPP accepts both encodings, duplicate-key validation compares raw bytes, and public_key_hash_for_key_data preserves their different encoding-dependent hashes, as confirmed by the pinned rust-dashcore test_pubkey_hash. With scan keys [(1, sk), (2, sk)], sealing to ID 2 succeeds, but PrivateDocumentRecipientKeys::open returns index 0. EntryReader::read_received checks only ID 1, rejects the request as RecipientKeyNotUsable, and the returned cursor advances past it. Repeated with_recipient registrations for the same identity have the same first-match problem. Preserve the matching key-ID candidates until the DashPay reader applies its recipient_key policy at the entry's timestamp, and return the request once under an eligible ID. Add a regression with a disabled alias preceding an enabled alias.
- [SUGGESTION] packages/rs-sdk/src/platform/private_document_scan.rs:477-483: Preserve retryability when an older snapshot returns no entries
An empty page before the first page's total can be a legitimate older snapshot rather than malformed data. For example, after a page proves positions 0–3 with total_count 30, a fetch from position 4 can prove an older total_count of 4 and return no entries; the pinned GroveDB implementation supports this range, and the SDK's default one-block height tolerance can accept the older proof. This branch returns Error::Generic, whose can_retry() is false, so consumers using the SDK's retry classification treat temporary node lag as terminal. The concurrent completion path also returns Generic when its continuation is an empty older page at lines 565–567. Distinguish a snapshot ending at or before the requested cursor from malformed contents, optionally retry with a bounded policy, and return a typed retryable stale-snapshot error if progress remains impossible. Add scripted coverage for empty older snapshots in both paths.
- [SUGGESTION] packages/rs-sdk/src/platform/private_document_scan.rs:486-500: Expose authenticated page geometry instead of rediscovering it
The walker infers chunk size from page lengths and alignment before scheduling concurrent reads. Drive already obtains the authoritative chunk_power from the proof-authenticated PrivateDocumentStore element and uses private_document_entries_page_limit to determine the verified range, but discards that geometry when returning PrivateDocumentEntries. Expose the authenticated geometry through Drive's result and the proof-verifier layer, then use it here for scheduling. Concurrency and cross-snapshot continuation should remain in the SDK; exporting the existing authoritative value avoids independently encoding page-boundary assumptions and the extra sequential reads needed to discover them. The current inference matches the paging contract, so this is a non-blocking API and maintainability improvement, not a proof-verification defect or a GroveDB repair.
Your move: thepastaclaw requested changes on this head; dismiss the review or push a fix; thepastaclaw left review threads unresolved; resolve them.
Full checklist in the description.
…ts key
The scan credited an opened entry to the id of the first key that opened
it, and the DashPay reader checked only that id. One point can be held
under several ids: a disabled compressed key 1 and an enabled uncompressed
encoding of it as key 2, or two registrations of the identity's keys. A
request sealed to key 2 was then refused for key 1, and the cursor moved
past it.
`ReceivedPrivateDocumentEntry` now carries `recipient_key_ids`, every id the
point was given under for the identity across its registrations, in order
(`recipient_key_id` is the first). The reader checks each as sealing does at
the entry's time, and reads the request once, under the first eligible id.

…en fail retryably
A page from a position an earlier page showed the store holds can come from
a node behind, within the SDK's tolerance, whose older snapshot ends at or
before that position: an empty page. The walk refused it with
`Error::Generic`, which `can_retry` takes as terminal, in the pages read one
at a time and in a chunk's continuation alike.
Such a page is now fetched again, twice at most (`fetch_ahead_of`), and a
node still behind ends the walk, after the pages before it, with the new
retryable `StaleNodeError::PrivateDocumentStoreBehind { position,
total_count }`. An empty page from a snapshot that holds its position is
still refused as malformed. The first page is not checked: an empty first
page at the store's end is the store being read up.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…ts proof binds
Drive reads the store's chunk power from the store element a page's proof
binds, to settle the page, but dropped it from the result, so the SDK walk
learned the chunk size from page lengths with up to two pages read one at a
time first.
- `PrivateDocumentEntries` (Drive's type, which the proof verifier and the
SDK return) gains `chunk_power: Option<u8>`. Drive's read and its proof
verification fill it; a page read without a proof leaves it `None`, as the
response carries no chunk power (the server's unproved response would need
a new proto field). The mock encodes it.
- The walk takes a proved page's chunk size: every page after the first is
fetched at once from the first's end. A page proved with another chunk
size than the walk's ends the walk with an error. Without a chunk power,
the walk learns the size from page lengths as before.
A client-side read result: no consensus change.

Re-review — Final validation — Phase 1 + Phase 2
Verified the implementation and all 25 prior findings against head 8558e83; the prior issues are addressed, and no blocking defect remains. One documentation suggestion remains: append-time expiry checks use the supplied identity snapshot's mutable expiry limit, not historical authorization state. This was static verification only; current head-matched CI code checks pass, including Rust, WASM, JavaScript, Swift, Kotlin and integration tests, with review and hygiene checks pending.
Triage: critical by gpt-6.1-sol (effort low) — The large, intricate diff directly changes cryptographic signature handling in packages/rs-platform-encryption/src/private_document_envelope.rs and adds wallet key handling and authenticated request processing in packages/rs-sdk/src/platform/dashpay/private_contact_request.rs.
These findings are from an automated code review. Verify each finding against the current code and only fix it if needed.
In `packages/rs-sdk/src/platform/dashpay/private_contact_request.rs`:
- [SUGGESTION] packages/rs-sdk/src/platform/dashpay/private_contact_request.rs:975-985: Clarify expiry checks use the supplied identity snapshot
The statement that the signing key was not expired when the entry was appended needs a qualification alongside the historical-membership limitation. `signing_key_problem` evaluates the supplied snapshot's `expires_at`, while `identity_key_limits_update/state/v0/mod.rs::refusal_for_key` explicitly permits extending expiry and reviving an expired key. An unchanged entry appended after the original expiry can therefore be rejected with one sufficiently recent snapshot and accepted with a later snapshot whose expiry was extended past the entry time. Document that this checks the snapshot's current expiry limit against append time, rather than proving the limit that existed at append time. Add an expired-key → expiry-extension → rescan regression to make the restore behavior explicit; historical-state reconstruction is not required for this clarification.
…current limit
The reader checks a signing key's expiry against the entry's block time
using the expiry the identity given carries now, not the one the key had
when the entry was appended. An identity may extend a key's expiry,
reviving an expired key, so an entry signed after the key's first expiry
is refused against an identity read before the extension and read
against one read after it. The read's documentation now says so, beside
its note on historical key membership, and a test pins the expired,
extended, read-again sequence.

Re-review — Final validation — Phase 1 + Phase 2
Static verification of the complete requested range at 4386ec0 found no remaining actionable findings, and all 26 prior findings are fixed in the current source. Current CI reports no failed code checks; Rust workspace tests, Evo SDK and Dashmate tests, and the Dashmate-helper image build remain running, while wasm32 tests, JS builds and linting, Kotlin tests, and the Swift schema check have passed. No local builds or tests were run, and the supplied base-drift evidence reports no merge conflicts.
Triage: critical by gpt-6.1-sol (effort low) — The large, intricate change directly modifies signature and key handling in packages/rs-platform-encryption/src/private_document_envelope.rs and implements encrypted request authentication and shielded-funded sending in the SDK.
These findings are from an automated code review. Verify the current code and confirm that no unresolved issues remain.

…n older one added or hydrated
`add_known_contract`, `add_known_contracts` and `with_known_contracts`
replaced a held contract whatever its version, so an application
restoring an older cached contract while a page verification ran could
put back a contract without the private type the verification had
resolved, and the page would then be refused. They now keep a held
contract of a higher version, as `register_data_contract` does, through
one rule both providers share; an equal version still replaces.
An explicit replacement stays possible: `replace_known_contract` puts a
contract in place of whatever is held, which the wasm SDK's
`addKnownContract` seed now calls, keeping its documented replacement
with an older or equal version.

…nd's activation refusal
An unpinned SDK below protocol version 15 refreshes its version before a
private document send, and refuses when it is still below. The refresh
swallowed its failure, so the refusal carried no cause and
`is_transient_protocol_version_refusal` read it as final: a caller
stopped retrying although the network may serve version 15 already, the
refresh having failed only for want of an answer.
The send now keeps the refresh's failure as the refusal's cause, as a
failed probe is the cause of the gate's own refusal; the pin and the
network's version read as before. `refresh_protocol_version` keeps its
signature.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…promoted during the fetch
A private page read fetches the contract declaring the type when the
provider holds none that does. A fetched contract without the type was
refused at once, although another operation may have given the provider
a newer contract declaring it while the fetch ran; the read then failed
for a contract the provider already held. The provider is now asked
again first, and a newer contract declaring the type is used; otherwise
the refusal, and its protocol-version form below version 15, stand.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…t hold or probe
`network_proven_below` answered, for an SDK that cannot ask the network
(no context provider, or no gate enforced), whether any version had
been verified below the one asked. A version verified earlier, perhaps
by a clone, does not show what the network runs now: after an upgrade
it still read as below, so a caller took a refusal as "not active yet".
That branch now answers no; the network reads as proven below only
while a probe's epoch hold shows it, or once a probe does.
A test's `mock_verified_protocol_version` now also sets such a hold,
outlasting the test, so a mock network set below a version still reads
as proven there.

Allow the activation gate to probe before refusing the send.
When an unpinned SDK starts below version 15 with proofs disabled, refresh does nothing. The send then returns a non-transient activation refusal without checking the network. Allow the gate’s proved probe to run before refusing so the SDK can discover version 15.

When the SDK starts below version 15, the refresh ignores PutSettings::request_settings. A stalled epoch request can therefore wait longer or retry more often than the caller configured. Pass the settings through to both epoch queries before awaiting the refresh.

Basic explanation
What this does: the Rust SDK can now send and find DashPay private contact requests.
PrivateContactRequest, sealing one, and a reader that checks each request against its sender's and recipient's keys.A private request is signed by one of the sender's signing keys, as a public request's transition is, with the same identity signer. The signature sits inside the encrypted entry: only the recipient sees it.
Value: this is the client half of anonymous DashPay contact requests (protocol version 15). Until now the chain could store private entries (#5799, #5804) and the envelope could seal and open them (#5806), but nothing in the SDK sent the transition or walked the store. Wallets, wasm-sdk and the mobile SDKs build on these calls.
Risks: low. It is client code only, with no consensus change. It also changes the envelope's signature mode in
platform-encryption(#5806). Nothing uses that mode yet and nothing is deployed, so the change breaks nothing.Issue being fixed or feature implemented

If the provider still gives the old one afterwards, or none, the helper fails at once instead of failing every page's proof.ContractBounds::check_document_typeanswers Allowed, Denied, or "needs the contract group's members", which only state can answer. The SDK's existingencrypted_forkey check, the signing key check and both encryption keys of a private request use it. A group bound is refused.contactRequestorprivateContactRequest.contactRequestis allowed because DashPay requires bound encryption and decryption keys for it, and apps register their DashPay keys bound to that type. Keys bound to another contract, another DashPay type or a group are refused, in the seal and in the reader.expires_atare refused, at the entry's block time in the reader and at the device's clock when sealing.contract_id,document_type_name), andprivate_contact_requests_from_scanrefuses a scan holding an entry of any store but DashPay'sprivateContactRequest.PrivateDocumentScanKeys::derivebuilds scan keys from key paths.How Has This Been Tested?

DocumentsBatchTransitionMethodsV0::combined_security_level_requirement(batch transition methods v0, every protocol version that authorizes document batches) now returnsSecurityLevel::document_signing_levels()of its strongest requirement instead of computing the range inline. Consensus cannot change: the new helper returns, for everySecurityLevel, exactly the vector the old code built, namely[MASTER]for MASTER andCRITICAL..=requirementin the same order otherwise. The only other difference is that theunwrapin the old range conversion is gone. dpp tests pin the outputs for each of the four requirements, a mixed batch, a token batch and an empty batch.Breaking Changes
None for consensus. dpp gains
ContractBounds::check_document_typeandDocumentTypeBoundsCheck, a pure client-side helper that consensus does not call. The new SDK functions changed their signatures during review (see above); none had shipped. Inplatform-encryption,PrivateDocumentSender::Signaturetakes a signature instead of a secret key, the signature signs the double SHA-256 of the signing data, and the authenticated data of every mode names the recipient key. Nothing used these modes yet.Checklist:
