January 2026 monthly summary for AurevoirXavier/polkadot-sdk. Focused on maintainability improvements and cross-version compatibility to support broader deployments with reliable builds. Delivered two key updates: code cleanup in pallet-revive and Rust toolchain compatibility enhancements, reinforcing long-term stability and ease of future maintenance.

December 2025 delivered significant stability and testing enhancements for AurevoirXavier/polkadot-sdk. Key outcomes include improved EVM test reliability, removal of unstable host functions, ecosystem-aligned test fixtures, and deterministic CI tooling. These changes reduce production risk, improve developer productivity, and strengthen cross‑chain compatibility across the project.

In 2025-11 for AurevoirXavier/polkadot-sdk, delivered observable, high-confidence changes in pallet-revive focused on correctness, observability, and cross-platform reliability. Implemented EVM selfdestruct tracing with contract address, beneficiary, gas remaining, and value transferred, plus CI updates to execute tests for both PVM and EVM. Fixed critical fund-bias in CREATE2 deploys by charging existential deposit only for new accounts and added a regression test to prevent double funding. Implemented storage zero-byte write removal and refund to fix storage accounting and gas refunds, with tests for simple and delegate-call scenarios. These changes improve security, developer experience, and overall system reliability with better test coverage and cross-platform validation.

Month 2025-10 performance summary for AurevoirXavier/polkadot-sdk: Strengthened testing reliability for EVM instruction verification in pallet-revive, enhanced developer tooling and CI/CD parity with Deno-based test runs, and aligned contract termination semantics with EIP-6780 with delayed destruction.

September 2025: Delivered extended EVM opcode coverage for pallet-revive in clangenb/polkadot-sdk, expanding the EVM backend with a comprehensive set of missing opcodes across arithmetic, bitwise, host, memory, and stack categories. Added Solidity test contracts for each opcode category and updated benchmarking/testing infrastructure to validate the new opcodes. These changes improve contract compatibility, reliability, and performance visibility for pallet-revive deployments.
