Filecoin Message

filecoinrpc/message

One Filecoin message (transaction) by its CID: sender, recipient, nonce, value in attoFIL and FIL (exact strings, 1 FIL = 10^18 attoFIL), gas limit, fee cap and premium, the actor method and its parameters. A CID the node does not know is found false. Only recent history is held. Read from public Filecoin Lotus nodes that offer no SLA and can be slow or throttled; they keep only about two weeks of mainnet history (one day on Calibration) and are run by one operator. Served by Eden Engine; not an official product of Filecoin, Protocol Labs or any node operator.
