feat(platform-wallet): support DashPay shielded tips with dedicated accounts - #5288
DashPay users have no way to receive private payments by username. This PR lets an identity publish a reusable shielded (Orchard) tip address on its DashPay profile and lets a wallet pay a username's tip address. Each wallet identity's tips land in a dedicated ZIP-32 account, so tip viewing keys stay separate from ordinary wallet activity. An externally generated Orchard address can be published instead.
This PR is now the first of a stack of three. Until 2026-10-30 it also carried the Swift and Kotlin tip screens (120 files). Review found that those screens made decisions that belong in Rust: which account pays, when a failed tip may be retried, and when a recipient counts as changed. The work is now split, and the order matters, because the safety logic lands in Rust before the screens that rely on it:
This PR: the wallet, storage and C/JNI/Swift/Kotlin SDK bindings, with no tip screens.
Follow-up (draft, linked below once open): moves the remaining tip decisions into rs-platform-wallet: an in-flight tip survives a relaunch, failures are classed as definite or uncertain so hosts know whether a retry is safe, recipient changes are detected, and each restored identity's slot is tracked as verified or not (Shielded tips in the example apps: restart-safe submission and identity-scoped source account #5674).
Follow-up (draft): thin Swift and Kotlin tip screens built on 1 and 2.
What was done?
Dedicated accounts. A wallet identity at derivation index i uses account 0x40000000 + i. prepare_shielded_tip_address proves with the seed that the identity holds that slot, binds the account and flushes persistence before returning the address. Identity discovery rebuilds tip accounts without the profile, and retired accounts keep scanning.
Publishing.PlatformWallet::write_dashpay_profile carries the core, platform and shielded payment addresses as explicit keep/set/remove updates, so unrelated profile edits keep them, and checks that the connected chain's contract has the field. It refuses one of this wallet's tip addresses unless that address was prepared in this session for the identity at the slot it holds now.
Placement lock. A per-wallet identity_placement lock orders identity moves against the tip operations that depend on the moving identity's slot. Discovery, loading and changeset apply take it to move an identity. Preparation, publication and tip sends hold it, so an identity cannot change slot between the check and the bind or spend.
Paying a username.resolve_shielded_tip returns the verified identity and address for the user to confirm. send_shielded_tip re-resolves, refuses if either changed, and takes a ShieldedTipSource. Identity(id) pays from that identity's tip account after the seed proves the slot it holds. Account(n) pays from an ordinary account, or from the tip account of an empty (retired) slot. The source has the same shape in C (ShieldedTipSourceFFI), JNI, Swift (ShieldedTipSource) and Kotlin.
Persistence. The PR adds SQLite migration V020, a Room migration from 15 to 16 (16.json), and a SwiftData PersistentDashpayPaymentAddresses model in the live V4 schema. Payment addresses restored from a host are validated again.
FFI. The tip exports resolve their wallet, coordinator and seed inside panic boundaries. A send failure reported as unconfirmed keeps its do-not-retry contract.
Example apps: only what the SDK change needs: storage-explorer coverage for the new SwiftData model, and identity deletion removing that model's rows.
How Has This Been Tested?
Local: cargo fmt, the wallet CI clippy command (-D warnings, all targets and features, wallet crates plus rs-unified-sdk-ffi/-jni), platform-wallet clippy without the shielded feature, and every test of the three wallet crates (1728 wallet lib, 567 storage integration, 505 FFI).
New: should_order_an_identity_move_after_tip_preparation_and_refuse_its_stale_address covers an identity whose keys derive at two indices. An identity move waits for preparation, and publishing the address prepared for the old slot is refused. The test fails if preparation does not take the lock.
should_refuse_tip_account_for_a_placeholder_index_until_it_is_verified now covers both sources and the publication refusal. should_decode_each_tip_source_kind_and_reject_others covers the C source struct.
Swift and Kotlin were not built locally; CI builds and tests them.
Breaking Changes
These are client-side only; there is no consensus or protocol change, so the title has no !.
C ABI.IdentityEntryFFI and ContactProfileRowFFI gained the payment addresses, and platform_wallet_manager_send_shielded_tip takes a *const ShieldedTipSourceFFI in place of account. Rebuild the xcframework and the JNI library together with host code.
Rust API. The profile models and rs-sdk's ProfileFields gained the payment address fields. PaymentAddressUpdate moved to dash_sdk::platform::dashpay, and platform-wallet re-exports it. send_shielded_tip takes a ShieldedTipSource. DashPayView::{create,update}_profile_with_external_signer are now crate-private; use PlatformWallet::write_dashpay_profile, which checks tip addresses.
Swift.PersistentIdentity.remove(in:identityId:) now throws, and sendShieldedTip takes source: in place of account:.
Kotlin.sendShieldedTip takes source: in place of account:.
Persistence. The migrations above are forward-only; downgrading a migrated database to an older SDK is not supported.

Live V4 adds PersistentDashpayPaymentAddresses, which sorts ahead of
PersistentIdentity and renumbers it from 13 to 14. Core Data embeds the
ordinal in generated column names, so the token-balance table's
Z13TOKENBALANCES foreign key becomes Z14TOKENBALANCES with its values
intact. validatePreservation normalized Z_<n> join-table names but not
the Z<n><NAME> column form, so the V1 -> V3 -> V4 and historical
V2 -> V3 -> V4 migrations were reported as removing a column
(DashModelMigrationTests, CI on #5288).
validatePreservation now keys columns by entity name for the
cross-store comparison; a dropped or type-converted column is still
rejected. layout()/evidence() keep their existing keys so recovery
journals written by earlier builds still verify.
Test: a renumbered copy of the dash-v1 fixture (entity inserted at 8,
join-table and generated columns renamed) passes; the same copy with
the column dropped or converted to VARCHAR is rejected.

Final validation — Phase 1 + Phase 2
Verified the supplied findings against head 02460d6 and confirmed four issues involving identity-placement persistence, restart-safe submissions, identity-specific spending-account selection, and concurrent account binding. These are client-side defects, classified as suggestions under the supplied policy reserving blocking severity for consensus invariants. Validation was static: the supplied CI snapshot reports successful Rust workspace and Kotlin checks, skipped dedicated wallet tests, and Swift build/tests still in progress.
Triage: critical by gpt-6.1-sol (effort low) — The large, cross-language diff directly changes key derivation and dedicated account handling in packages/rs-platform-wallet/src/wallet/shielded/tips.rs, funds submission in packages/rs-platform-wallet-ffi/src/shielded_send.rs, and persisted-data migrations in SQLite, SwiftData, and Room.
These findings are from an automated code review. Verify each finding against the current code and only fix it if needed.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/state/manager/lifecycle.rs:206-207: Preserve corrected identity indices through changeset merging
The new adoption path changes identity_index, but IdentityChangeSet::merge never copies that field into an existing entry. With SQLite FlushMode::Manual, a snapshot buffered at placeholder index 0 can therefore absorb the subsequent discovery snapshot at verified index 5 while retaining index 0. Both Buffer::normalize_identities and the final buffered merge use these semantics, so flush/reload restores the incorrect placement. The same stale slot also remains occupied during buffered admission checks, potentially rejecting another identity that discovery places into the freed slot.
Make identity_index follow the latest snapshot alongside wallet_id. Add a SQLite regression that buffers an old-slot snapshot, adopts the identity into its verified slot, persists the resulting snapshot, then flushes and reloads; also verify that another identity can occupy the freed slot.

- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/DashPay/ShieldedTipSubmission.swift:28-32: Restore outstanding tip submissions before enabling another send
The submission guard and wallet map are memory-only, and each new process initializes the guard to ready. Kotlin's ShieldedTipSubmissions has the same lifecycle. Restarting after a broadcast with an unresolved outcome therefore removes the warning and permits the user to retry the same intended payment as a new transfer. A relay withholding confirmation is sufficient to create this ambiguity; process termination during broadcast also exposes it.
Rust records pending transfer activity and can redrive the original transition, but transfer reserves individual input notes rather than a payment intent. Additional spendable notes can fund the retry, allowing both transfers to execute. Persist an unresolved intent before entering the native send, restore its guard before enabling submission, and reconcile it with the original activity or transition. Add process-recreation coverage with an ambiguous original transfer and additional spendable notes; the existing reopening tests retain the same in-memory owner.
In `packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/DashPay/DashPayProfileView.swift`:
- [SUGGESTION] packages/swift-sdk/SwiftExampleApp/SwiftExampleApp/Views/DashPay/DashPayProfileView.swift:39-44: Verify the identity index before selecting its tip spending account
Rust's optional index getter returns recorded metadata, not a verified identity-to-account association. The mobile restore path constructs ManagedIdentity::new(identity, spec.identity_index), so a persisted placeholder zero becomes Some(0). The existing should_refuse_tip_account_for_a_placeholder_index_until_it_is_verified regression demonstrates an identity belonging at index 5 restored at index 0 while index 0's tip account is bound.
Preparation rejects this association by checking the seed, but this balance/spending selector and Kotlin's corresponding selectors bypass that check. They can display index 0's funds as belonging to the restored identity and pass that account to the send API, which validates account keys but receives no source identity to verify. Resolve identity-specific tip accounts through a verified wallet operation, or disable these selectors until the association is verified. Extend the placeholder regression to cover balance lookup and spending-account selection, not only address preparation.
In `packages/rs-platform-wallet/src/wallet/shielded/tips.rs`:
- [SUGGESTION] packages/rs-platform-wallet/src/wallet/shielded/tips.rs:142-147: Make tip preparation an atomic augmentation of the bound account set
The account snapshot and replacement bind are separate operations. Preparation can snapshot ordinary account 0, another task can finish binding accounts 0 and 1, and preparation can then bind its stale snapshot plus the tip account. bind_shielded automatically retains discovered and persisted tip accounts, but not omitted ordinary accounts. Consequently, register_locked removes account 1 from registration and purges its live subwallet state, contradicting preparation's ordinary-account preservation guarantee.
The shield guard and coordinator install transaction serialize individual installations, not the preceding read-modify-write sequence. Serialize configuration changes across the snapshot and bind, or provide an augmentation operation that merges with the current registration inside the installation transaction. Add a deterministic interleaving regression proving that an ordinary account added during preparation remains bound.
Out-of-scope follow-up suggestions (1)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
Seed verification runs while holding the wallet-manager read guard — The guard covers bounded synchronous derivation and verification with no network call or await inside the guarded block. Writers are briefly excluded, but the finding supplies no demonstrated hot-path or material contention problem; moving this work outside the lock is an optional optimization rather than a confirmed review defect.
Follow-up: Consider creating a separate issue or author/maintainer-requested PR for this.

Not addressed in this PR; it needs a maintainer call on scope. The description has listed this thread as open since the PR was recreated. The finding holds: ShieldedTipSubmission (ShieldedTipSubmission.swift:25-32) and Kotlin's ShieldedTipSubmissions keep their guard in memory, so a relaunch after an uncertain broadcast starts in .ready. Because the native send reserves notes rather than a payment intent, a retry can pay the recipient again.
Closing that needs a durable outstanding-intent record in both example apps and a reconciliation against native activity on relaunch. That's new persistence plus recovery UI, which I'd rather keep out of this already large change and land as a follow-up with the process-recreation test you describe.

Fixed in #5709, stacked on this PR: the wallet now owns restart safety, so a relaunch can't repeat an unsettled tip.
Recorded before broadcast.send_shielded_tip flushes the pending activity row to the host, then arms a parked recovery record in the shielded store (Rust's own SQLite), and only then broadcasts. The record is parked, meaning its re-drive budget is already spent, so the sync re-drive can't re-broadcast it alongside the original broadcast.
How it settles. The send's own outcome drops the record (sent, or definitively rejected) or re-arms it for re-drive (unconfirmed). After a crash, the scan settles it when it sees the notes spent, or the anchor-prune pass does.
What is refused. While a payment to an address is unresolved, a tip to it is refused (ShieldedTipPending). That includes the address last confirmed for the name, in case the recipient rotated it. A second tip while one is being sent is also refused rather than queued.
Tests. The parked guard is armed with its budget spent and fails closed without an activity row; an ambiguous result reactivates only a guard that is still armed; and the unresolved check covers a rotated address, a missing activity row, other spend kinds and other wallets.

Re-review — Final validation — Phase 1 + Phase 2
Static verification confirms the original concurrent-bind race and buffered identity-index merge defect are fixed, and the reported occupied-placeholder spending case is now rejected before recipient resolution. Six client-side suggestions remain concerning restart recovery, stale source-account selection, identity replay, account preservation, and test isolation; no consensus-blocking defect was confirmed. No builds or tests were run, and the supplied exact-head CI snapshot still had most validation queued or pending.

🟡 Suggestion: Serialize shielded_add_account with the new shielded config lock packages/rs-platform-wallet/src/wallet/platform_wallet.rs:1154-1160
Tip preparation now holds shielded_config_lock across its account snapshot and replacement bind, but shielded_add_account writes the same shielded_keys map without participating in that lock. Preparation can snapshot [0], an addition can persist and insert ordinary account 1, and preparation can then install its stale snapshot plus the tip account, overwriting the completed insertion while leaving its viewing-key row persisted. This breaks the new preparation helper's ordinary-account preservation guarantee even though the concurrent-bind case is fixed. Acquire the same configuration lock for the complete add operation, preserving the existing rule that host callbacks run outside the key-slot guard. The add API intentionally does not register accounts with the coordinator itself, so this finding concerns loss of its in-memory insertion, not a claim that it creates a coordinator registration. Extend the interleaving coverage to race preparation with this writer.

- [SUGGESTION] packages/kotlin-sdk/KotlinExampleApp/app/src/main/java/org/dashfoundation/example/ui/dashpay/DashPayTabScreen.kt:336-345: Invalidate and reverify the source account when an identity is re-slotted
The lookup keys include the wallet wrapper, manager, and identity ID, but not the identity's placement. This PR allows discovery to move that same identity from placeholder index 0 to verified index 5 without replacing those objects. If discovery completes while this composition is alive, the cached result remains `0x40000000` and is still offered as that identity's dedicated source account. A blocking discovery can continue natively after its search screen is dismissed, so returning to DashPay before it finishes can expose this interleaving. The new Rust check does not reject the stale source: `verify_tip_account_owner` succeeds when slot 0 has become empty, and also succeeds if the rightful identity 0 later occupies it. A confirmed send can thus spend the retained account-0 funds rather than the selected identity's account-5 funds. Invalidate the lookup when verified placement changes and recheck the selected source identity/account association at submission; checking only the account's current occupant is insufficient. Add a regression resolving at placeholder 0, adopting into 5, and attempting a send with the old selection. The profile-screen lookup also needs placement-change invalidation.
In `packages/rs-platform-wallet/src/wallet/identity/state/manager/lifecycle.rs`:
- [SUGGESTION] packages/rs-platform-wallet/src/wallet/identity/state/manager/lifecycle.rs:195-207: Carry identity relocation through changeset replay
Adoption now changes bucket placement and identity coordinates, but `IdentityManager::apply_identity_entry` still updates an existing identity in place and returns without applying `wallet_id`, `identity_index`, or `location_index`. Replaying valid snapshots A@0, then adopted A@5, then newly admitted B@0 through the public `PlatformWallet::apply` or `PlatformWalletInfo::apply_changeset` API leaves A at slot 0 until B's fresh insertion overwrites it. A's state is lost and its reverse-index entry still points to slot 0, so `identity(A)` returns B. Promotion from the observed bucket likewise fails to reproduce the adoption. Normal startup reconstruction uses a different path, which limits the current impact, but the public replay API no longer reproduces the mutations introduced here. Apply relocation while preserving managed state and reverse-index consistency, reject unrelated occupied targets, and handle merged batches independently of identity-ID ordering when one entry frees another's slot. Add round-trip coverage for observed-identity promotion and A@0 → A@5 followed by B@0.

For a wallet already bound to ordinary accounts `[0, 1]`, Rust adds discovered and persisted tip accounts but does not retain omitted ordinary account 1. `NetworkShieldedCoordinator::register_locked` consequently removes account 1's registration and purges its live notes and watermark, so discovering identities unexpectedly stops an existing ordinary account from scanning. Swift preserves a snapshot of ordinary accounts, but its snapshot and replacement call are also outside the native configuration lock. Provide a refresh operation that reads the current configuration and adds discovered tip accounts atomically under `shielded_config_lock`, and use it from discovery rather than treating `[0]` as a complete replacement configuration. Keep full bind available for intentional replacement. Cover discovery refresh starting from `[0, 1]` and verify that both ordinary registrations survive.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/platform_wallet.rs:1154-1160: Serialize shielded_add_account with the new shielded config lock
Tip preparation now holds `shielded_config_lock` across its account snapshot and replacement bind, but `shielded_add_account` writes the same `shielded_keys` map without participating in that lock. Preparation can snapshot `[0]`, an addition can persist and insert ordinary account 1, and preparation can then install its stale snapshot plus the tip account, overwriting the completed insertion while leaving its viewing-key row persisted. This breaks the new preparation helper's ordinary-account preservation guarantee even though the concurrent-bind case is fixed. Acquire the same configuration lock for the complete add operation, preserving the existing rule that host callbacks run outside the key-slot guard. The add API intentionally does not register accounts with the coordinator itself, so this finding concerns loss of its in-memory insertion, not a claim that it creates a coordinator registration. Extend the interleaving coverage to race preparation with this writer.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/shielded/tips.rs:258-263: Isolate the preparation pause hook by wallet instance
The global pause hook is consumed using only the deterministic wallet ID. The concurrency regression, placeholder-index regression, and discovery/restoration regression all create independent testnet wallet instances from `MESSAGE_SIGNING_TEST_MNEMONIC`, so they share that ID. Under parallel execution, another test's preparation can remove the concurrency test's hook and signal `reached` while holding its own configuration lock. The intended preparation then runs without pausing, allowing the competing bind to complete inside the timeout and failing the regression despite correct production locking. Attach the hook to shared state belonging to the actual wallet instance, use an instance-specific token, or give the concurrency fixture a distinct deterministic mnemonic. The current wallet-ID key does not provide the parallel-test isolation claimed by the comment.

(existing thread: https://github.com/dashpay/platform/pull/5288#discussion_r4185823786)
The shared owner preserves the submission guard across sheet dismissal, but a new process reconstructs an empty wallet map and a `.ready` submission. Kotlin has the same lifecycle. After termination during an accepted-but-unconfirmed send, reopening therefore removes the uncertainty warning and permits the user to confirm the same payment again. Native pending activity and redrive records do not prevent this: note reservations exclude particular inputs, while `reserve_unspent_notes` can select other funded notes for a fresh transfer. The redrive transaction itself is armed only after an ambiguous broadcast result returns, so process loss during the call also cannot be treated as a recovered safe retry. Persist a network/wallet-scoped unresolved intent before entering native spending, restore its warning before enabling confirmation, and reconcile native activity or require explicit acknowledgment that another submission is a separate payment. Add process-recreation tests using newly constructed owners and sufficient independent notes to fund both attempts. The PR's pending maintainer decision is not an implemented recovery boundary.
Re: the review's non-inline finding "Serialize shielded_add_account with the new shielded config lock" (platform_wallet.rs:1154-1160).
Confirmed and fixed in 93d4d3b. shielded_add_account now takes shielded_config_lock after its attachment check, before its key-slot read. Host callbacks still run outside the key-slot guard, and the lock order (config lock, then shield_guard / shielded_keys) is unchanged.
The new regression should_keep_an_added_account_during_tip_preparation pauses preparation after its snapshot, races shielded_add_account(1) against it, and checks that account 1 is still bound afterwards. The test fails without the lock.

Re-review — Final validation — Phase 1 + Phase 2
At head 6c88c31, the configuration-locking, pause-hook isolation, and identity-index merge fixes are present, but three client-side suggestions remain around merged replay, queued source-account selection, and restart-safe submission state; no consensus blocker was confirmed. All nine prior findings were independently reconciled, with the acknowledged balance-provenance follow-up kept deferred. Validation was static only: the supplied CI snapshot shows Rust workspace and Kotlin checks passing, the dedicated wallet job skipped, and PR Hygiene pending; the Swift failure log confirms “database is locked” in testCaptureHistoricalV2Fixture.

- [SUGGESTION] packages/rs-platform-wallet/src/wallet/apply.rs:162-170: Carry identity relocation through changeset replay
The new ordering handles sequential relocation, but it still evaluates occupancy against transient state rather than the merged batch's final survivors. Starting with A@0, merge the changesets from moving A to 5, removing A, and inserting B@5. IdentityChangeSet::merge retains both A's snapshot and tombstone, so this partition postpones A's removal. Replay moves A to 5, skips fresh B because A occupies 5, then removes A and returns success with B missing. B's subsequent key/contact entries cannot route, and applying the batch again can produce a different result.
The relocation loop in identity/state/manager/apply.rs has another instance of the same final-state problem: A@0/B@1 ending at A@1/B@0 remains blocked and falls back to in-place updates. The public adoption API can produce those final snapshots through free slot 2, and SQLite's check_index_conflicts explicitly accepts a two-way swap, so replay can disagree with persistence even for a conflict-free final batch.
Remove all tombstoned identities before placement and exclude their snapshots. Stage surviving relocations so valid cycles can be installed while preserving managed state and reverse-index consistency. Add regressions using actual merged mutation changesets, checking replay against the final persisted placement and checking repeated application.

The placement keys now refresh the account offered by the open sheet, but confirmation copies it into sendAccount before history.confirm suspends on Dispatchers.IO. Discovery can move the selected identity A from placeholder 0 to verified 5 during that suspension. Subsequent recomposition cannot change the account captured by the application-owned submission, so the native call still receives 0x40000000.
Rust's verify_tip_account_owner accepts that account if slot 0 is empty, or verifies its rightful replacement B if B now occupies slot 0.

(existing thread: https://github.com/dashpay/platform/pull/5288#discussion_r4185823786)
The application-owned guard survives navigation, but its status and registry are memory-only. After process termination, forWallet creates a submission in ready without consulting persisted outgoing activity or recovery state. Kotlin's registry has the same lifetime boundary, and recipient confirmation history records the destination rather than the payment outcome.
If the process exits after broadcast but before the result reaches the host, relaunch permits a fresh attempt while the first payment may already have executed or remain eligible for redrive. Native reservations protect the first payment's nullifiers, not the logical payment: operations::transfer selects other available notes without an unresolved-intent check. With another sufficient note set, both transfers can execute and pay the recipient twice. This is duplicate payment, not a consensus double-spend.
Persist an unresolved intent before entering the native send, restore a conservative reconciliation state before enabling another attempt, and clear it only after a definitive outcome. Add process-recreation coverage with an unresolved first payment and enough other notes to fund another transfer; the current tests reuse the same submission owner.

Leaving this one for the maintainer review rather than fixing it in this PR. The race is real: ShieldedTipSheet.kt:95 captures sendAccount before history.confirm suspends at line 98. A re-slot of the selected identity inside that one preferences write would send from the old slot's tip account. verify_tip_account_owner (tips.rs:169) only proves that the account is wallet-owned, not that it belongs to the identity the user picked.
The fix you describe is the right shape, but it changes the native send in every layer (Rust, C FFI, JNI, Swift, Kotlin) so that it carries the expected identity. That's a sizeable ABI change on top of an already large PR, for a window the user can only hit by running discovery during that write. No funds leave the wallet either way; the wrong pool can pay. I'd take it as a follow-up with the regression you outline.

Still applies (re-reviewed at 4d92dc45): The sheet still captures the account before the suspending confirmation write, and the native API still receives no expected source identity, so a re-slot during that write can select the old identity-specific pool.

Still applies (re-reviewed at 7a242efd): Placement-keyed lookup refreshes do not protect the account captured by the open sheet or the native send's pre-await owner check. A re-slot can still leave the send using an empty retired slot or another identity's now-current slot, so the selected identity must be carried through and revalidated before spending.

Fixed in c5daa28. The native tip send no longer takes an account number: send_shielded_tip takes a ShieldedTipSource (packages/rs-platform-wallet/src/wallet/shielded/tips.rs), and the same shape goes through C (ShieldedTipSourceFFI), JNI, Swift and Kotlin.
Identity(id) pays from the tip account of the slot the seed proves the identity holds. The check runs at send time, under the per-wallet identity_placement read lock, and the lock is held through note selection. Discovery, loading and changeset apply take it for writing before they move an identity, so a re-slot waits for the send rather than redirecting it.
Account(n) is the explicit route: an ordinary account, or the tip account of an empty (retired) slot. It refuses a tip account whose slot holds an identity.
The Kotlin sheet that captured the account has moved out of this PR. The screens come back in the stacked follow-up, built on the identity source.
should_refuse_tip_account_for_a_placeholder_index_until_it_is_verified covers both sources before and after a re-slot, including that Identity(id) maps to the proved slot's account.

Resolved (re-reviewed at c5daa28d): Your c5daa28 source type carries the selected identity through C, JNI, Swift, and Kotlin, and Rust proves its current slot under the placement guard held through spending.

The client-only diff preserves proof-verified recipient resolution and addresses the reported identity-replay, account-configuration locking, and changeset-merging defects.

The source account is copied into sendAccount before history.confirm suspends on Dispatchers.IO. Discovery can move the selected identity from placeholder slot 0 to verified slot 5 during that suspension. A subsequent Room update cannot change the captured argument, and the JNI/C send signatures carry the recipient identity but no expected source identity. Rust's verify_tip_account_owner accepts the emptied slot-0 account, so with sufficient retained notes the payment can spend account 0x40000000 instead of the selected identity's account-5 pool. This is a source-selection error, not an unauthorized-spending bypass: both pools remain wallet-owned. Carry the selected source identity and confirmed account through the identity-specific submission path, reject a changed association before spending, and require renewed review. Preserve explicitly selected retired-account spending separately. Add an interleaving regression that relocates the source while confirmation-history persistence is suspended.

The placement key fixes eventual cache invalidation, but there is also a window before Room delivers the changed placement. Native discovery updates the identity manager first; until the corresponding row reaches composition, tipAccountKey still matches the old result and the sheet can confirm that account as the selected identity's dedicated source. Reading the current prop at confirmation does not close this window. The native ownership check validates the account's current occupant, not the selected source identity, and deliberately permits an empty retired slot. Retaining that policy is reasonable, but this identity-selected flow should not silently substitute the retired pool. Keep the Room-key fix and validate the expected source identity/account association natively at submission. Cover relocation before the corresponding Room emission, separately from relocation after the sheet captures its argument.

Every reconstructed submission starts ready, and both apps retain their per-wallet guards only in memory. Restarting after a broadcast with an unresolved outcome therefore enables another confirmation without restoring the previous sending/uncertain state. Native recovery does not make this payment-intent-safe: PendingRedrive is armed after an ambiguous result returns, and even a surviving record reserves only the original transaction's notes. reserve_unspent_notes can select other available notes for a fresh transfer, allowing both payments to execute if the user repeats the apparently unfinished tip. Persist an unresolved submission marker by network and wallet before invoking native send, restore it before enabling payment, and reconcile it with shielded activity/recovery state. Add reconstruction tests with a new submissions owner over the same durable state; the current reopening tests exercise only the existing owner. The description identifies a pending maintainer decision, but the current implementation still has this limitation.
Out-of-scope follow-up suggestions (1)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
Track verified identity placement for tip-balance attribution — The restore path constructs ManagedIdentity::new(identity, spec.identity_index), so a historical placeholder zero becomes Some(0). Swift and Kotlin balance selectors consequently can attribute retained account-0 notes to an identity actually derived at index 5. Native seed checks reject preparation and spending while that incorrect identity occupies the slot, but do not verify the displayed balance. This is the concrete balance-display remainder explicitly separated into a follow-up in the author's response, not a new finding to reopen here.
Follow-up: Track derivation-verification provenance and expose an identity-aware tip-account resolver through the native bindings, with an unverified presentation state and placeholder-restore coverage.

Confirmation copies tipAccount into sendAccount before history.confirm suspends on Dispatchers.IO to commit preferences.

Native send_shielded_tip receives only the numeric source account, and verify_tip_account_owner accepts the old account when slot 0 is empty or contains its correctly derived owner.

Application ownership preserves the guard across navigation, but the wallet dictionary and submission status are entirely process-local. After termination during broadcasting or following an uncertain result, relaunch constructs a new submission in ready state without restoring the outstanding payment. Kotlin's application-owned submissions have the same boundary. Native recovery can reconcile or redrive the original transition, but reserve_unspent_notes selects available notes without deduplicating the recipient/amount intent; a fresh submission can use other notes and pay the recipient again. Persist an outstanding intent before invoking native send, restore it into an unresolved state before enabling another submission, and reconcile it against native activity before clearing the guard. The existing reopen tests retain the same submission owner; add a reconstruction regression using a new owner after an accepted-but-unconfirmed attempt.

The placement-keyed lookup refreshes subsequent compositions, but this submission captures only a numeric source account before `history.confirm` suspends on Dispatchers.IO. Discovery can move identity A from restored placeholder index 0 to verified index 5 during that suspension, and the resumed submission still passes account 0x40000000. Native `verify_tip_account_owner` accepts that account when slot 0 is empty, or when its correctly derived identity subsequently occupies it; the send boundary receives no selected source identity to detect that the account no longer matches A. Allowing explicitly selected retired accounts is valid, but it does not preserve this UI's promise to spend from the selected identity's dedicated account. Carry the selected source identity and expected account association into the native identity-specific send operation and reject a changed association before selecting funds, while preserving explicit retired-account spending separately.

Both example apps keep submission guards exclusively in memory, so a new process creates an empty registry and initializes each wallet to ready. Termination after broadcast but before observing its outcome, or after an unconfirmed result, therefore removes the warning and permits an apparent retry as a new payment. Native activity/redrive records protect the original transaction, and note reservations exclude its selected inputs, but `operations::transfer` independently selects other available notes for a new call; neither mechanism deduplicates the user's payment intent. With sufficient additional notes, both transfers can execute. Persist an unresolved submission marker before entering native spending, restore it before enabling another send, and reconcile it against durable activity/recovery information or require explicit acknowledgement of the unresolved payment. Add a cold-recreation regression: the existing reopen tests retain the same application-owned guard and do not exercise process restart. The PR description's open maintainer decision does not establish an implemented recovery path or an agreed exclusion.

Propagate contact-profile fetch failures on the absent-profile path.
If this fetch throws, try? returns nil. The branch then skips deleting the old profile row. The preceding PersistentDashpayPaymentAddresses.replace call has already staged deletion of the address sidecar. The round can then commit that state and report success, which leaves a stale contact profile without its addresses. Using try makes the error reach the do block in persistIdentities. That block returns false, so the round fails and its staged changes roll back. The identity-removal path in the same function already uses try for this kind of fetch.
Suggested fix
- if let existing = try? backgroundContext.fetch(descriptor).first {+ if let existing = try backgroundContext.fetch(descriptor).first {
backgroundContext.delete(existing)

Re-review — Final validation — Phase 1 + Phase 2
Static verification at c5daa28 confirms the identity-aware spending, placement synchronization, persistence, and FFI lifetime fixes. Two blocking issues remain: ordinary-send balances include dedicated tip funds they cannot spend, and non-shielded builds discard valid shielded-address metadata; one lock-scope improvement is also actionable. Current CI passes Kotlin build/tests, JS builds, Swift frozen-schema validation, and storage-explorer coverage; Rust workspace and JS package tests remain pending, and no local builds or tests were run.
Triage: critical by gpt-6.1-sol (effort low) — The large, intricate diff directly changes funds-source selection and seed-proved account binding in packages/rs-platform-wallet/src/wallet/shielded/tips.rs and introduces persistent storage migrations, including V020__profile_address_encoding.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-platform-wallet/src/wallet/platform_wallet.rs`:
- [BLOCKING] packages/rs-platform-wallet/src/wallet/platform_wallet.rs:873-874: Exclude dedicated tip funds from ordinary-send source balances
Automatically adding discovered tip accounts to an ordinary account-0 bind now puts their notes into existing wallet-wide balance queries. Kotlin's SendTransactionScreen.kt:200-201 sums every unspent note for the wallet, and Swift's SendTransactionView.swift:495-496 sums a query whose predicate filters only wallet ID and spent status. Those screens nevertheless spend exclusively from account 0: Kotlin uses the default account argument, and Swift's SendViewModel explicitly passes account: 0 for transfer, unshield, and withdrawal. A wallet funded only through a dedicated tip account therefore offers a funded shielded source that cannot complete the displayed send; mixed ordinary/tip funds overstate that source's spendable balance. The account filter added to Kotlin ShieldedService does not affect these independent screen queries.
Keep automatic tip-account recovery, but make ordinary spending and funding consumers obtain a balance scoped to the account their native operation spends, preferably using the Rust per-account balance API. Cover both an empty account 0 with funded tip accounts and mixed ordinary/tip balances in both hosts. Removing the dedicated tip screens does not remove these existing consumers.
In `packages/rs-platform-wallet/src/wallet/identity/types/dashpay/profile.rs`:
- [BLOCKING] packages/rs-platform-wallet/src/wallet/identity/types/dashpay/profile.rs:120-123: Preserve stored shielded addresses when shielded support is disabled
Without the shielded feature, this helper returns None even for a valid Orchard address. Both platform-wallet and platform-wallet-ffi default to builds without that feature, and this helper is used for canonical metadata ingestion, not only payment eligibility: profile_from_restore_row hydrates owned and contact profiles through it, while profile_from_properties uses it for network synchronization. Restoring a valid stored address therefore removes it from ManagedIdentity state, and a subsequent identity snapshot persists that absence back to the host. During sync_profiles, a profile containing only a shielded address also becomes the default empty profile, which cacheable_profile converts into authoritative whole-profile absence.
Separate retaining profile metadata from deciding whether this build can pay an address. Preserve valid address metadata independently of spending capability, or return an explicit unsupported-validation error without replacing existing state. Add non-shielded coverage for restoring a valid stored address followed by an unrelated identity snapshot, and for synchronizing an address-only profile.
In `packages/rs-platform-wallet/src/wallet/shielded/tips.rs`:
- [SUGGESTION] packages/rs-platform-wallet/src/wallet/shielded/tips.rs:306-317: Narrow identity_placement hold to source check and spend in send_shielded_tip
The placement read guard remains held while resolve_shielded_tip performs DPNS resolution and a proof-verified profile fetch. That resolution uses the SDK rather than wallet placement, so its network latency unnecessarily delays discovery, identity loading, and changeset application waiting for the placement write lock, in addition to the time required for proving and broadcasting.
Resolve and compare the recipient before acquiring the guard that pins the source through spending. If rejecting invalid sources before network access is intentional, retain a short initial source preflight, release its guard for recipient resolution, then reacquire the guard and revalidate the source immediately before spending. Keep the final source check and transfer under one uninterrupted placement guard.

Re-review — Final validation — Phase 1 + Phase 2
Verified the combined findings and all 36 prior findings against e8e518f. Two blockers remain: feature-disabled profile restoration loses stored shielded addresses, and ordinary-send selectors include dedicated-account funds they cannot spend; two suggestions cover placement-lock duration and suppressed contact-profile fetch failures. This was static verification only: current Rust workspace, Swift, Kotlin, and JS code checks pass, while PR Hygiene remains pending.

🟡 Suggestion: Propagate contact-profile absent-path fetch failures instead of committing a half-cleared round packages/swift-sdk/Sources/SwiftDashSDK/PlatformWallet/PlatformWalletPersistenceHandler.swift:4049-4050
The confirmed-absent branch first stages payment-address sidecar deletion, then suppresses errors while fetching the contact-profile row. If that fetch fails, the stale profile remains while the sidecar deletion can commit and persistIdentities reports success. This PR adds the sidecar mutation and makes the helper throwing, so the existing suppressed fetch now permits a partial application of the new profile state. Use try so the error reaches persistIdentities' catch, returns failure through the callback, and causes endChangeset to roll back the staged changes.

(existing thread: https://github.com/dashpay/platform/pull/5288#discussion_r4436951939)
This branch controls canonical profile reconstruction, not only payment capability. Both profile_from_properties and the FFI's profile_from_restore_row use validated_shielded_address, so a build without shielded support restores a present address as None. Both crates support this configuration by default. An unrelated identity snapshot then carries that absence into Swift's sidecar replacement or Kotlin's profile upsert, clearing the persisted address without an explicit removal. Keep semantics prevent an unrelated edit from removing the on-chain field, but do not prevent this local persistence loss. Separate metadata preservation from payment validation: retain stored address data when shielded support is unavailable, and refuse unsupported resolution or spending independently. Add a feature-disabled restore, unrelated snapshot, and repersist round-trip regression.
In `packages/rs-platform-wallet/src/wallet/platform_wallet.rs`:
- [BLOCKING] packages/rs-platform-wallet/src/wallet/platform_wallet.rs:873-874: Exclude dedicated tip funds from ordinary-send source balances
(existing thread: https://github.com/dashpay/platform/pull/5288#discussion_r4436951935)
Binding ordinary account 0 now also binds discovered identities' dedicated accounts and retains persisted tip accounts, so their scanned notes enter the existing wallet-wide persistence queries. Swift SendTransactionView.shieldedBalance sums every unspent note for the wallet, but SendViewModel's transfer, unshield, and withdrawal paths explicitly spend account 0. Kotlin SendTransactionScreen independently sums observeUnspentNotesByWallet and submits the same operations with their account-zero defaults. Swift CreateIdentityView also offers funding denominations from a wallet-wide sum while creating the identity from account 0. A tip-only wallet therefore advertises an available ordinary source that cannot fund a submission, and mixed balances overstate the selected source's funds. Filtering Kotlin ShieldedService does not cover these direct database consumers, and removing the tip screens does not remove automatic binding. Preserve wallet-wide totals, but expose and consume the balance of the actual spending source in ordinary-send and identity-funding selectors. Cover tip-only and mixed-account balances in both hosts. Note selection remains account-scoped; this is a balance-reporting and source-availability defect, not evidence that ordinary sends automatically consume dedicated notes.
In `packages/rs-platform-wallet/src/wallet/shielded/tips.rs`:
- [SUGGESTION] packages/rs-platform-wallet/src/wallet/shielded/tips.rs:306-312: Narrow identity_placement hold to source check and spend in send_shielded_tip
(existing thread: https://github.com/dashpay/platform/pull/5288#discussion_r4436951943)
The placement read guard is acquired before resolve_shielded_tip performs its DPNS and profile network requests. Discovery, identity loading, and identity changeset application need the write side, so a slow recipient lookup delays unrelated placement operations for its full retry/timeout duration, even for an ordinary Account source. Recipient lookup and comparison do not depend on source placement. Resolve and compare the recipient before acquiring the final placement guard, then select and validate the source under that guard and retain the guard through the source-dependent spend. If rejecting an invalid source before network access is intentional, perform a preliminary check and repeat the authoritative check after resolution. The existing check-through-spend synchronization should remain intact.

- review_shielded_tip supplies the recipient, the changed-recipient warning
and the unresolved-payment block; the host-side recipient history is gone.
- A failed send is shown by its ShieldedTipFailure disposition; the
error-category allow-lists are gone, and an unresolved send no longer
locks the wallet's other tips (the wallet refuses that recipient itself).
- Amounts are parsed by parse_shielded_tip_amount and the confirmation shows
the parsed amount.
- The tip sheet pays from an identity source, and the profile shows a tip
balance only when identity_tip_account reports the slot verified.

The Swift and Kotlin apps regain the tip screens that #5288 moved out: the
username tip sheet, the profile's tip address and balance, the post-discovery
rebind, and the tip-account balance filters. They now render the wallet's
decisions instead of making them:
- review_shielded_tip supplies the recipient, the changed-recipient warning
and the unresolved-payment block; the host-side recipient history is gone.
- A failed send is shown by its ShieldedTipFailure disposition; the
error-category allow-lists are gone, and an unresolved send no longer
locks the wallet's other tips (the wallet refuses that recipient itself).
- Amounts are parsed by parse_shielded_tip_amount and the confirmation shows
the parsed amount.
- The tip sheet pays from an identity source, and the profile shows a tip
balance only when identity_tip_account reports the slot verified.

Issue being fixed or feature implemented
DashPay users have no way to receive private payments by username. This PR lets an identity publish a reusable shielded (Orchard) tip address on its DashPay profile and lets a wallet pay a username's tip address. Each wallet identity's tips land in a dedicated ZIP-32 account, so tip viewing keys stay separate from ordinary wallet activity. An externally generated Orchard address can be published instead.
The contract field shipped in #4768 and the DPNS resolver fix in #4769. This follows #4380 and dashpay/dips#188.
This PR is now the first of a stack of three. Until 2026-10-30 it also carried the Swift and Kotlin tip screens (120 files). Review found that those screens made decisions that belong in Rust: which account pays, when a failed tip may be retried, and when a recipient counts as changed. The work is now split, and the order matters, because the safety logic lands in Rust before the screens that rely on it:
rs-platform-wallet: an in-flight tip survives a relaunch, failures are classed as definite or uncertain so hosts know whether a retry is safe, recipient changes are detected, and each restored identity's slot is tracked as verified or not (Shielded tips in the example apps: restart-safe submission and identity-scoped source account #5674).What was done?
iuses account0x40000000 + i.prepare_shielded_tip_addressproves with the seed that the identity holds that slot, binds the account and flushes persistence before returning the address. Identity discovery rebuilds tip accounts without the profile, and retired accounts keep scanning.PlatformWallet::write_dashpay_profilecarries the core, platform and shielded payment addresses as explicit keep/set/remove updates, so unrelated profile edits keep them, and checks that the connected chain's contract has the field. It refuses one of this wallet's tip addresses unless that address was prepared in this session for the identity at the slot it holds now.identity_placementlock orders identity moves against the tip operations that depend on the moving identity's slot. Discovery, loading and changeset apply take it to move an identity. Preparation, publication and tip sends hold it, so an identity cannot change slot between the check and the bind or spend.resolve_shielded_tipreturns the verified identity and address for the user to confirm.send_shielded_tipre-resolves, refuses if either changed, and takes aShieldedTipSource.Identity(id)pays from that identity's tip account after the seed proves the slot it holds.Account(n)pays from an ordinary account, or from the tip account of an empty (retired) slot. The source has the same shape in C (ShieldedTipSourceFFI), JNI, Swift (ShieldedTipSource) and Kotlin.16.json), and a SwiftDataPersistentDashpayPaymentAddressesmodel in the live V4 schema. Payment addresses restored from a host are validated again.How Has This Been Tested?
cargo fmt, the wallet CI clippy command (-D warnings, all targets and features, wallet crates plusrs-unified-sdk-ffi/-jni),platform-walletclippy without the shielded feature, and every test of the three wallet crates (1728 wallet lib, 567 storage integration, 505 FFI).should_order_an_identity_move_after_tip_preparation_and_refuse_its_stale_addresscovers an identity whose keys derive at two indices. An identity move waits for preparation, and publishing the address prepared for the old slot is refused. The test fails if preparation does not take the lock.should_refuse_tip_account_for_a_placeholder_index_until_it_is_verifiednow covers both sources and the publication refusal.should_decode_each_tip_source_kind_and_reject_otherscovers the C source struct.Breaking Changes
