Structs

Config

Configuration options for instantiating a FireblocksSigner

FireblocksMiddleware

The FireblocksMiddleware is an ethers-compatible middleware which sends transactions and signs messages using Fireblocks’ API. Sending transactions utilizes the CONTRACT_CALL mode and signing messages utilizes the RAW mode.

FireblocksSigner

FireblocksSigner is a Signer which utilizes Fireblocks’ MPC signing over its API instead of a local private key.
