v1.5.0 - Bridge Cleanup & Unified Token Architecture

Changes

Bridge Cleanup

• Removed 5 non-bridging choices from WayfinderBridgeConfig:
  • RegisterUser - registration now happens via direct FingerprintMapping creation
  • GetMetadata - metadata available via TokenConfig
  • AddAuditObserver / RemoveAuditObserver - observer management via TokenConfig
  • DirectMint - minting via TokenConfig.IssuerMint
• Bridge contract now only handles: CreatePendingDeposit, ProcessDepositAndMint, InitiateWithdrawal

Version Bump

• All 9 DAML packages bumped to v1.5.0 for consistency

v1.4.0 - Unified Token Architecture

What's Changed

Unified Token Architecture

• TokenConfig (CIP56.Config): Single entry point for all mint/burn operations, replacing split NativeTokenConfig/bridge-specific logic
• Unified Events (CIP56.Events): MintEvent/BurnEvent with optional bridge metadata (evmTxHash, evmDestination)
• Thin Bridge Layer: WayfinderBridgeConfig delegates all mint/burn to TokenConfig -- adding a new bridged token means creating another bridge config pointing at a different TokenConfig instance

Anti-fragmentation

• CIP56Holding.Transfer now accepts existingRecipientHolding to merge into existing holdings, preventing UTXO-style fragmentation

Cleanup

• Removed deprecated packages: native-token, bridge-usdc, bridge-cbtc, bridge-generic, dvp
• Removed deprecated modules: Bridge.Events, Bridge.Types, Native.Events, Native.Token, CIP56.Transfer
• Updated build/test/clean/deploy scripts for active packages only
• Updated documentation and README with unified architecture diagrams

Active Packages (all at v1.4.0)

• common - Shared types, fingerprint mapping
• cip56-token - CIP56Holding, TokenConfig, Events
• bridge-core - MintCommand, WithdrawalRequest
• bridge-wayfinder - Wayfinder PROMPT token bridge
• common-tests, cip56-token-tests, bridge-core-tests, bridge-wayfinder-tests
• integration-tests

v1.1.0 - Issuer-Centric Model

Breaking Changes

• Removed legacy user-driven templates:
  • MintProposal
  • MintAuthorization
  • RedeemRequest
  • BurnEvent
• Removed CreateMintProposal choice from WayfinderBridgeConfig

Migration Guide

The issuer-centric model is now the only supported flow:

Deposits (EVM → Canton)

Use MintCommand + ExecuteMint:

mintCmdCid <- submit issuer $ createCmd MintCommand with ...
holdingCid <- submit issuer $ exerciseCmd mintCmdCid ExecuteMint

Withdrawals (Canton → EVM)

Use WithdrawalRequest + ProcessWithdrawal:

withdrawalReqCid <- submit issuer $ createCmd WithdrawalRequest with ...
withdrawalEventCid <- submit issuer $ exerciseCmd withdrawalReqCid ProcessWithdrawal

Other Changes

• Updated bridge-core-tests to use issuer-centric flow
• Updated TESTING.md documentation
• All 13 packages bumped to v1.1.0
