Worked on the matter-labs/zksync-era repository to deliver the Era upgrade path from v29 to v31, focusing on robust, production-ready blockchain upgrades. Leveraged Rust and Solidity to implement on-chain timestamp validation and event-driven upgrade processing, introducing v31-specific transaction data rewriting for accurate chain-specific calldata. Modernized upgrade event handling by integrating ServerNotifier updates and simplifying data lookups, which reduced upgrade risk and latency. Updated governance flows, refreshed ABIs, and ensured compatibility by pinning contract submodules. Comprehensive validation included protocol-ops phases and integration tests, reinforcing upgrade reliability and correctness across networks while removing outdated harnesses and aligning with private test repositories.

May 1, 2026May 2026 monthly summary for matter-labs/zksync-era: Delivered the Era upgrade path from v29 to v31, enabling robust, production-ready upgrades with on-chain timestamp validation and event-driven upgrade processing. Implemented v31-specific upgrade tx data rewriting to populate chain-specific calldata before upgrade execution. Updated upgrade flow to listen to ServerNotifier::UpgradeTimestampUpdated and simplified diamond_cut_for_version lookups, reducing upgrade-risk and latency. Consolidated changes across zkSync-era components, refreshed ABIs and governance paths for v31, and pinned the contracts submodule to matter-labs/era-contracts#2174 to ensure compatibility. Removed outdated local upgrade harnesses and aligned with private upgrade-tests repo. Validation included five protocol-ops phases completed in paired local reth+zkstack flow; 16 non-prividium integration tests passed; 182 tests passed, 4 skipped; L1 protocol version verified at 0.31.0. This work improves upgrade reliability, reduces downtime risk, and reinforces upgrade correctness across networks.
