Mar 1, 2025March 2025 — chainwayxyz/clementine: Delivered Citrea integration for cross-chain deposits/withdrawals with light client proofs, including modules and client types for Citrea's EVM contracts, withdrawal UTXO fetching, contract interactions, light client proofs, and an end-to-end test setup. Implemented watchtower capability with environment-based configuration via .env, updated documentation, and removed obsolete config. Streamlined tests and tuned cryptographic parameters by reducing verifiers and dynamically calculating BRIDGE_PARAMS from the default BridgeConfig. Fixed env config bug by removing the watchtower_challenge_message_length field. Business impact: enables reliable cross-chain settlements, faster deployments, and more maintainable tests; technical impact: robust EVM integration, cleaner configuration, and optimized crypto parameters.
