This project upgrades the Filfox Filecoin explorer to improve observability and verification of Filecoin Onchain Cloud activity, with first-class support for PDP and Filecoin Pay. It adds accurate FEVM subcall execution tracing, structured runtime and relationship views for datasets and payment flows, and a discoverable registry of core FOC service contracts, enabling developers, storage providers, exchanges, and integrators to more reliably interpret on-chain behavior and reduce integration and troubleshooting costs.
