Extended contract data model with renewedFrom/renewedTo and added navigation buttons to visualize contract lineage, improving traceability of renewals. Expanded event types and dynamic formatting for payouts to reflect miners, foundations, and siafundClaims, improving accuracy and clarity of displays. Refactored internal API typings and structure to improve type safety, align routes with new endpoints, and reorganize explorer components for maintainability. Fixed a bug in contract ID handling by ensuring v2ContractByID receives an object with an id field, reducing API errors. These changes improved business value by delivering more complete activity signals, reducing API errors, and improving developer productivity through safer typings and cleaner component structure.

Feb 1, 2025In February 2025, completed a major migration of the data source from siaCentral to the explored API, updating host data structures and UI to consume explored data, adding hostsList support, and removing external dependencies. Implemented UI/UX and design-system improvements, enhanced end-to-end tests, and introduced client-side timestamp rendering. Fixed critical correctness issues, including transaction confirmations now counting the current block, and strengthened top-host data handling with improved caching and error reporting. This work reduces external risk, improves data freshness and UI reliability, and demonstrates strong API, caching, and frontend engineering capabilities.
