Filecoin — State, Wallet (3/3)

API reference for Filecoin. All methods ->

Part 3 of 3: 1 · 2 · 3

Filecoin.StateSearchMsg​

Searches for a message in the chain, and returns its receipt and the tipset where it was executed.

NOTE: If a replacing message is found on chain, this method will return a MsgLookup for the replacing message — the MsgLookup.Message will be a different CID than the one provided in the ‘cid’ param, MsgLookup.Receipt will contain the result of the execution of the replacing message.

If the caller wants to ensure that exactly the requested message was executed, they MUST check that MsgLookup.Message is equal to the provided ‘cid’. Without this check both the requested and original message may appear as successfully executed on-chain, which may look like a double-spend.

A replacing message is a message with a different CID, any of Gas values, and different signature, but with all other parameters matching (source/destination, nonce, params, etc.)

Filecoin.StateWaitMsg​
