June 2025 monthly summary for Agoric/agoric-sdk: Delivered strong GMP-related work and cross-chain capabilities, with a focus on Axelar GMP integration, test coverage, and reliability improvements that translate to tangible business value and faster delivery of cross-chain features. Key features delivered include Axelar GMP contract implementation, core-eval/bootstrap tests, GMP workflow documentation, and environment-based Axelar chain configuration. We also established a foundational GMP setup (Initial GMP Setup) and EXO groundwork for Aave and Compound, enabling cross-chain asset management and future expansion. Major bugs fixed encompass stability and reliability improvements: contract restart test, mutability fixes via mapStore usage, getAccount test fixes, remote EVM account tweaks (Dont exit seat inside initRemoteEVMAccount, shared accounts for EVM transactions), and address validation safeguards to prevent invalid deployments. Overall impact and accomplishments: notable progress towards a robust cross-chain pipeline, improved test stability, and preparation for production-like scenarios (deploy funds to Aave/Compound, CCTP-based token transfers). Documentation and CI hygiene improvements reduce onboarding time and increase maintainability. Technologies/skills demonstrated: Solidity/TypeScript development, GMP framework, remote EVM and EXO integration, CCTP asset transfers, advanced test patterns (mocking, memo construction tests), state hardening with hardened() calls, keeper interface refactor, and modern CI/CD practices (CI workflow updates, yarn.lock upkeep, removal of esbuild bundling).
