Jul 1, 2025July 2025 monthly summary focused on delivering gas-pricing infrastructure for Zilliqa/zq2. Implemented RPC APIs for gas data access and dynamic fee calculation to help clients optimize transaction inclusion and cost. The changes are recorded in commit 265ee3b9b0d9b3776276a86fa560692d22c32248 with message: 'Implement `eth_feeHistory` and `eth_maxPriorityFeePerGas` APIs (#2221)'. No major bugs fixed this month; minor stability and quality improvements accompanied the rollout. Overall impact: enhances client ability to plan and optimize transactions through historical gas data and dynamic prioritization, improving user experience and reducing failed/overpaid transactions. Technologies/skills demonstrated: backend API design, Ethereum-compatible RPC development, performance-conscious data exposure, versioned API rollout, Git-based change traceability, and cross-functional collaboration with the zq2 repo.

Mar 1, 2025March 2025 (2025-03) monthly summary for Zilliqa/zq2 focused on API correctness and gas accounting reliability. Delivered two critical fixes with explicit commits, improving contract state retrieval, gas economics, and configurability. Highlights: 1) GetSmartContractSubState API correctness: fixed contract address handling and index behavior; returns empty vector when no indices are provided and ensures correct balance/storage sub-states. Commit 49a68378a0f298d783a4a49fbca3f7624b321967. 2) Gas fee transfer to zero account bug fix and configurability: fixed incorrect transfer value to the zero account; introduced config option transfer_gas_fee_to_zero_account; ensures cumulative gas fees are calculated and transferred; updates to chain specs and consensus logic. Commit ed5df897f9d531cdd278c6f5c8a8850a25c8decd. Overall impact: improved correctness and reliability of contract state queries, more predictable gas accounting, and alignment of chain economics with specifications. Technologies/skills demonstrated: Rust-based API and contract state handling, gas accounting logic, runtime configurability, chain specs and consensus adjustments, and strong commit traceability.
