June 2026 — Delivered Network Support Deprecation in smartcontractkit/chain-selectors by deprecating polygon zkEVM and Botanix mainnet selectors in configuration, preparing for future removal of deprecated networks. This reduces configuration surface area and maintenance overhead while aligning with the roadmap. Commit: 7379cdd69bb7d45be27444a842b0b6db7b29b64b (decom polygon zkEVM and botanix mainnet).

March 2026 summary: Implemented configurable RPC health check timeout in the chainlink deployments framework to improve reliability under high concurrency and large-scale deployments. Fixed issues caused by a hardcoded 2s timeout, preventing failures during health checks for 80+ chains in state generate. Updated the EVM chain loader to use HealthCheckTimeout of 15s, reducing context deadlines exceeded. This enhances stability for testnet/mainnet deployments and increases scalability.

January 2026 (2026-01) Monthly Summary for smartcontractkit/chain-selectors. This month focused on expanding multi-network support by adding Pharos mainnet and ADI networks (testnet/mainnet) to the chain selectors, enabling broader network coverage and faster onboarding for new ecosystems. Commits updated chain IDs, selectors, and generated chains with clear traceability to specific changes.

2025-12 Monthly Summary: Expanded multi-chain support by delivering Jovay blockchain log processing for the RPC client in smartcontractkit/chainlink-evm. Implemented Jovay updates to makeLogsValid and chain type definitions, added Jovay log processing tests, and linked to commit 36a18321243c712e05630fd0d353b6ac39d77dcb. Business impact includes enabling Jovay deployments with reliable log handling, reducing integration risk, and broadening client coverage. Technologies demonstrated include Go-based RPC client changes, type-definition updates, and test-driven development.

Concise monthly summary for 2025-11 focusing on delivered features, improvements, and business impact across two repositories. Emphasis on user experience, testing flexibility, and reliable automation.

October 2025 monthly summary for smartcontractkit/chain-selectors: Delivered AB Network support by adding AB Mainnet and AB Testnet configurations to the generated Go file and selectors YAML, expanding network compatibility and enabling faster integration for AB ecosystem deployments. The changes were implemented as a config-layer enhancement with isolated impact on network selectors.

September 2025: Delivered expanded multi-network support and stabilized dependencies to strengthen multi-chain capabilities and reduce maintenance risk. Key progress includes Jovay mainnet support in chain selectors and a critical dependency upgrade that improves compatibility across repos.

April 2025 focused on dependency hygiene and stability for smartcontractkit/chainlink. Upgraded the chain-selectors library to v1.0.48, aligning with latest fixes and features, improving compatibility and enabling future performance gains from the updated library. Delivered via a targeted patch (bump chain-selectors) with commit 3991bcb0a498fb9d3bf6b6793efd970d652daf20. This work reduces maintenance risk and positions the project to leverage upstream improvements.
