Concise monthly summary for informalsystems/malachite (2025-10): Implemented ECDSA signing capabilities via a dedicated signing-ecdsa crate, enabling multi-curve support (k256, p256, p384) and wiring necessary dependencies and serialization logic for cryptographic operations within the consensus engine. This work establishes a flexible cryptographic foundation for secure signing workflows and interoperability with multiple curve families.

Month: 2025-08 — Monthly summary for informalsystems/ibc-starknet. Focused on delivering upgradeability, security, and cross-chain interoperability features with robust CI improvements. Key achievements this month include the following feature deliveries and improvements across StarkNet IBC integration:

July 2025 performance summary for informalsystems/ibc-starknet: Delivered Starknet light client integration with block header verification for IBC, including encoding/validation refactor, dependency updates, and ADR documentation. No major bugs fixed this month; focus on feature delivery and documentation to strengthen cross-chain security and reliability.

June 2025 performance summary for informalsystems/ibc-starknet: Focused on architectural improvements, cryptography modernization, and observability to drive maintainability, deployment efficiency, and security. Delivered core utilities consolidation via ibc_utils and standardization of Array<u8>, modularized IBC contracts using library contracts to shrink CASM size and simplify deployments, modernized cryptography with Poseidon hashing from starknet-crypto and garaga-based Ed25519 verifier, and enhanced observability through gas-usage logging and dependency updates across crates. These changes yield reduced contract size, faster deployments, stronger cryptography, and improved runtime telemetry for cost-aware operations.

May 2025 monthly summary for informalsystems/ibc-starknet: Delivered three major features focused on tooling, verification, and CI visibility. Key achievements include upgrading internal tooling and dependencies, introducing a Starknet Block Verifier crate with CI/test integration, and enabling CI visibility for Cairo contract sizes. These efforts improve development velocity, reliability of block validation, and transparency into contract footprint, directly supporting product reliability and cost planning.

April 2025: Implemented key cross-chain interoperability improvements for informalsystems/ibc-starknet, including StarkNet v0.13.5 compatibility, enhanced IBC transfer reliability, cross-chain readiness with CometBFT, and CI/templating improvements. These efforts improved reliability, security, and speed-to-delivery for multi-chain deployments, enabling more robust cross-chain assets transfers and smoother developer workflows.

During 2025-03, the informalsystems/ibc-starknet project delivered key cross‑chain interoperability enhancements, security hardening, and tooling improvements that collectively increase data reliability, testnet readiness, and developer productivity. Key achievements focused on Starknet integration, testnet onboarding, and secure configuration management, underpinned by CI/ tooling upgrades that improve build and test performance.

February 2025: Focused on hardening cross-chain security and reliability in informalsystems/ibc-starknet. Delivered verification of Starknet signed commitment proofs to strengthen light-client validation; fixed critical height tracking and consensus state handling, and expanded CI coverage. Improved Starknet configuration and address handling to support Cairo contracts and clearer address/URL presentation. Added ERC20Metadata support to ICS20, standardizing decimals. Updated build tooling and dependencies to align with Osmosis and Scarb releases, and invested in code quality with linting and TOML maintenance. These changes collectively improve security, reliability, developer experience, and business value of cross-chain interoperability.

Concise monthly summary for 2025-01 focusing on business value and technical achievements for informalsystems/ibc-starknet. This month centered on delivering robust cross-chain capabilities between IBC and StarkNet, strengthening reliability, testing, and maintainability through targeted feature work and essential fixes.
