Feb 1, 2026February 2026 Sei-chain monthly summary: Implemented performance forecasting and robustness enhancements with clear business value. Introduced a theoretical TPS calculation based on instant block arrivals to forecast system performance under optimal conditions; added unit tests and benchmark script logging to validate the new metric. Strengthened Demo Chain initialization robustness by adding --overwrite flag support in the benchmark script to satisfy a new check, reducing setup friction for demos and testing. Overall impact: improved capacity planning, faster QA/demo cycles, and more reliable deployments. Technologies demonstrated: benchmarking, automated testing, script instrumentation, and flag handling in automation workflows.

Dec 1, 2025Month: 2025-12 — In Sei-chain, focused on reliability of price data and strengthening governance-testing coverage. Delivered two primary efforts: 1) Price Feeder Concurrency Safety with a locking mechanism around SetPrices to prevent race conditions on concurrent reads/writes, accompanied by a new unit test to guard against data races. 2) WASM Governance Enabling/Disabling Tests, a comprehensive test suite to verify governance controls over WASM instantiation, upload-code, and related flows, ensuring stability during state changes. These work items were delivered with strong commit-level traceability. Result: reduced race risk, improved stability under high load, and safer governance transitions. Impact on business value: more trustworthy price data feeds, safer protocol upgrades, and higher confidence for operators during deployments. Technologies/skills demonstrated: mutex locking/concurrency control, unit and integration testing, governance flow testing, WASM lifecycle validation, and test-driven development.

Nov 1, 2025November 2025 – Sei-Chain performance benchmarking enhancement and validation. Delivered EVM TPS Benchmarking Mode, enabling automated benchmarking by generating 1000 EVM transfer blocks and measuring transactions per second (TPS). Implemented supporting scripts and validated via local testing and unit tests. No major bug fixes were documented for this period in the provided data; stability improvements ongoing. Collaboration with team members (co-authored by Jeremy Wei) contributed to code quality and review coverage. This work establishes a foundation for formal performance benchmarking, observability, and capacity planning across the repo sei-protocol/sei-chain.

Oct 1, 2025October 2025 monthly summary for sei-chain. Delivered a central, unified EVM sender resolution in RPC and fixed critical issues that improved reliability and CI/CD resilience. Key work focused on consolidating EVM sender recovery through a new rpcutils tool and migrating to rpcutils.RecoverEVMSenderWithContext, improving sender data accuracy across RPC paths and for older transactions with chain ID 0. Also addressed CI/CD workflow authentication and bloom filter robustness to ensure stable builds and uninterrupted block processing.

Jul 1, 2025July 2025 performance summary for sei-protocol/sei-chain: Delivered targeted test coverage for CW20-to-EVM assets precompile and implemented a state-clearing optimization. The new test (ERC20toCWAssets) validates registering existing CW20 tokens as EVM pointers, integrated into TestParallelTransactions, with the test context updated to deploy CW20 tokens. Implemented account state clearing optimization to purge state only when a code hash exists; deleteIfExists now returns a boolean to signal deletion, enabling conditional clearing of related state data. These changes improve cross-chain asset reliability, reduce state churn, and accelerate CI feedback. Technologies/skills demonstrated include test automation, integration testing across components, and code refactoring for conditional logic to improve performance and maintainability.

Mar 1, 2025March 2025 monthly summary for sei-chain: Implemented centralized EVM contract address management via a new Config struct to standardize address handling across ERC20/ERC721 deployments and related protocols. Refactored load testing scripts for ERC20 and ERC721 and streamlined deployment/testing workflows. Added --broadcast flag to forge create deployments to support deterministic, reproducible builds. Fixed remapping for OpenZeppelin with a trailing slash and updated Uniswap V2 deployment logic to align with the new address management system. This work reduces operational overhead, increases test reliability, and improves deployment consistency across the ecosystem.
