## Summary With the Cardano **Chang hard fork** activated on mainnet (September 1, 2024), we need to track necessary updates on the `develop` branch to ensure our project remains compatible and up-to-date. ## Background The Chang hard fork marks the beginning of Cardano's **Voltaire era**, introducing on-chain governance via **CIP-1694**. Key changes include: - New governance bodies: Constitutional Committee, Delegate Representatives (DReps), and SPOs - Two-phase rollout: Chang #1 (bootstrap governance) and Chang #2 (full governance actions) - Requires Cardano node version 9.0+ - New governance action types (hard fork initiations, parameter changes, treasury withdrawals, etc.) ## Action Items ### 1. `package.json` Dependency Updates - [ ] Audit all Cardano-related dependencies (e.g., `@cardano-sdk/*`, `lucid-cardano`, `@emurgo/cardano-serialization-lib`) for compatibility with node v9.0+ - [ ] Update any CIP-1694 governance-related libraries to their latest versions - [ ] Verify that transaction-building libraries support new governance certificate types - [ ] Run full test suite after dependency bumps on `develop` ### 2. Avalanche C-Chain Compatibility - [ ] Verify cross-chain bridge contracts still function correctly post-Chang - [ ] Ensure EVM compatibility layer handles any new Cardano governance-related transaction types - [ ] Update any C-Chain integration tests that interact with Cardano smart contracts - [ ] Document any breaking changes affecting Avalanche C-Chain interoperability ### 3. General - [ ] Update project documentation to reference the Chang hard fork and Voltaire era - [ ] Add changelog entries for all updates made on `develop` - [ ] Schedule a cross-team review before merging to `main` ## Branch All work should be tracked against the **`develop`** branch. ## References - [CIP-1694 Specification](https://cips.cardano.org/cip/CIP-1694) - [Cardano Chang Hard Fork Announcement](https://cardano.org) - [Voltaire Era Documentation](https://docs.cardano.org/about-cardano/evolution/voltaire) -- This is an automated message from the Apache Git Service.
