May 1, 2025

May 2025 monthly summary for axelar-amplifier. Delivered comprehensive backend and observability enhancements across the broadcaster and blockchain services, significantly improving scalability, reliability, and developer productivity. Key features include Broadcaster v2 with MsgQueueClient and gRPC broadcast, Blockchain gRPC Subscribe, Smart Contract State Access with improved error handling, and enhanced observability via structured logging. In addition, gRPC robustness was strengthened with transparent error propagation and properly unimplemented statuses, complemented by a TOFND gRPC client refactor to remove an unnecessary mutex, yielding measurable performance and concurrency benefits. These changes deliver tangible business value: faster transaction broadcasting, robust event subscriptions, clearer error surfaces for developers, and improved operational visibility.
