February 2026: Delivered frontend-level integration enabling local block explorer routing for CoW Protocol services, significantly improving development and testing by pointing links to a local Otterscan instance. The work lays groundwork for Milestone 2 Frontend Integration by centralizing explorer navigation in the local environment.

January 2026 monthly summary: Delivered two high-value features across cowprotocol repos with strong business value: (1) Configurable Block Explorer URL via environment variable to accelerate local development and testing with custom explorers, including a robust override path across common-utils and legacy address utilities; (2) CoW Protocol Playground Otterscan integration with Sourcify contract verification, enabling developers to browse transactions and view verified contracts locally via Dockerized services. Additionally, implemented a reliable env-based config flow, added debugging logs, and prepared groundwork for frontend explorer URL integration. These efforts reduced setup time for developers, improved contract verification workflows, and laid groundwork for enhanced frontend integration. Key bets and preparations: improved developer experience for local testing, strengthened contract verification visibility, and aligned with planned frontend explorer URL modifications.
