Aug 1, 2025August 2025 monthly summary for kaiachain/kaia focused on stabilizing RPC block-number semantics and improving developer experience. Delivered a feature that standardizes block interpretation by recognizing 'safe' and 'finalized' as aliases for 'latest' in the RPC layer, with accompanying tests to validate the behavior. This work reduces edge-case bugs for clients and lays groundwork for broader client tooling compatibility.

Jul 1, 2025July 2025 monthly summary for kaiachain/kaia. Focus: gas estimation alignment with Ethereum semantics to ensure reliable on-chain calls. No new user-facing features; one critical bug fix implemented to align kaia_estimateGas with eth_estimateGas, including correct handling of gas=0 for DoCall. This change reduces failed transactions and developer friction by ensuring default estimation behavior mirrors Ethereum's. Impact: improved reliability in gas estimation, consistency across RPC interfaces, and safer default behavior for DoCall and contract interactions. Technologies/skills: API design and RPC surface alignment, bug fix discipline, back-end gas estimation logic, and code hygiene; commit 6a62312b51321dc8882fe73910afc717b62e7100.
