Greg Jeanmart contributed to the safe-global/safe-client-gateway and safe-wallet-web repositories, focusing on backend and frontend improvements using TypeScript, NestJS, and React. He streamlined module architecture, consolidated APIs, and introduced per-request HTTP timeouts to enhance maintainability and reliability. Greg integrated Gelato relay for sponsored transactions on Unichain mainnet and implemented a circuit breaker to prevent cascading failures. He improved security analysis accuracy in safe-wallet-web by refining transaction simulation logic and addressed UI accuracy for beneficiary information. His work included refactoring, logging enhancements, and licensing compliance, demonstrating depth in API development, security analysis, and robust testing practices across complex distributed systems.
Month: 2026-03 – In March 2026, delivered observability and licensing compliance improvements for safe-client-gateway. Downgraded external request and hook event logs from info to debug to enhance debugging granularity. Added SPDX license identifiers to relevant files to improve licensing clarity and compliance. Updated tests to align with the new logging behavior and licensing changes, preserving regression coverage. These changes reduce debugging time, improve license transparency, and strengthen overall observability for external request flows.

February 2026 monthly summary for safe-global/safe-client-gateway. Delivered two high-impact capabilities that strengthen transaction support and system resilience: Gelato relay integration for Unichain mainnet enabling sponsored transactions, and a circuit breaker for getSafesByOwner with a centralized key utility. The changes enhance user experience for sponsored transactions, reduce risk of cascading failures in critical endpoints, and improve maintainability through centralized key management and targeted tests. Technologies showcased include Gelato relay, Unichain (chainId 130), circuit breaker pattern, and centralized key management with updated configuration validator tests.

December 2025 monthly summary for safe-client-gateway: Delivered a major architectural simplification, API surface cleanup, and reliability improvements that drive maintainability and business value. Key outcomes include a root-level module consolidation (affecting repository, API, and routes modules) with preserved backward compatibility; deprecation/removal of the old /v1/owners/:ownerAddress/safes endpoint with migration guidance to v1/v2 endpoints; and per-request HTTP timeouts added to NetworkRequest (default timeout, configurable per call) with tests and documentation. These changes reduce maintenance burden, accelerate onboarding for new contributors, and improve resilience for latency-prone endpoints.

November 2025 monthly summary: Delivered a targeted fix in safe-wallet-web to ensure correct beneficiary information is shown for spending limit transactions, improving UI accuracy and reducing user confusion. Implemented the COR-605 fix to resolve beneficiary name/logo using the decoded beneficiary address rather than the transaction's to address. Performed targeted code cleanup (removed redundant addressbook hook) and adopted a safer ZERO_ADDRESS constant. Completed lint improvements to raise code quality and consistency. Overall, these changes enhance trust in spending limit flows and simplify maintenance for the wallet UI integration with the beneficiary data model.

October 2025 monthly summary for safe-wallet-web: Implemented Blockaid analysis accuracy improvement by temporarily disabling Safe Guards during transaction simulation to ensure accurate security analysis results. Introduced a state_override mechanism to bypass Safe Guard configurations during simulation, addressing guard-induced interference and improving the reliability of security assessments and audit feedback.
