Understanding the FVM
summary
FVM already runs on the Falcon testnet (launched July 2022) and targets mainnet in ~40 days; it exposes a FEVM runtime as an on‑chain actor that maps EVM storage into IPLD using a new state CID-backed storage structure and adds Filecoin-specific precompiles (resolve_address, lookup_delegated, contract_id). It accepts EIP-1559 type‑2 transactions and translates them to Filecoin messages, offers ethereum JSON‑RPC compatibility so MetaMask/Hardhat/Remix/Foundry work, and meters gas via Filecoin’s model charging per Wasm instruction, so gas costs can change across upgrades.
