During a two-month period, Gutonosa enhanced reliability and compatibility across the matter-labs/foundry-zksync and foundry-rs/foundry repositories. They upgraded transaction encoding to EIP-2718 for Optimism support and improved error handling in Rust, preserving original error messages for better debugging. In foundry-rs/foundry, Gutonosa addressed trace accuracy by resetting contract decoders to prevent stale data and enforced per-transaction blob count validation to strengthen data integrity. Their work included serialization improvements using serde for backward compatibility and TOML support. Gutonosa’s contributions demonstrated depth in backend development, data structures, and serialization, resulting in more robust, maintainable, and interoperable systems.
