Luis Urrutia engineered core enhancements for the OpenZeppelin/openzeppelin-relayer repository, focusing on scalable multi-network support, robust transaction management, and secure cross-network signing. He implemented hierarchical network configuration using Rust and JSON, enabling flexible deployments and reducing duplication. Luis integrated advanced gas price estimation for networks like Optimism and Polygon zkEVM, introduced Google Cloud KMS and Turnkey signers for Stellar, and improved EIP-712 signing across EVM chains. His work included Docker and CI/CD optimizations, dependency upgrades, and rigorous error handling, resulting in more reliable, secure, and maintainable relayer infrastructure. The solutions addressed operational risk, onboarding friction, and cross-chain reliability.

October 2025 was a consolidated sprint toward cross-network signing capabilities, improved build reliability, and strengthened security posture. Major accomplishments include expanded Stellar signer support with Google Cloud KMS and Turnkey, cross-platform Docker build stability, and enhanced signer experience with EIP-712 signing and cross-network signer improvements. Additionally, we introduced MSRV checks in the update-lock workflow to improve Rust toolchain compatibility, and added a dedicated gas price estimation path for Polygon zkEVM to improve cost predictability and UX. These changes collectively reduce signing friction, improve CI reliability, increase security, and deliver more predictable gas economics for multi-network deployments.
