Raw Signing Objects

content

string/object

The content that was sent to be signed.

For RAW signing - the message for signing (hex-formatted).

For EIP712 Typed Message signing - the object (payload) for signing.

algorithm

string

The algorithm that was used for signing, one of the SigningAlgorithms

derivationPath

Array of numbers

BIP32 derivation path of the signing key. E.g.

signature

dictionary

The message signature

publicKey

string

The signature's public key is used for verification.

content

string

The message to be signed in hex format encoding

bip44AddressIndex

number

RawMess BIP44 address_index path level

bip44change

number

RawMess BIP44 change path level

The 2 fields above complement the derivation path given the source id and asset were provided in the transaction body request.

In case none of the above was provided, please specify the derivation path.

derivationPath

array of numbers

RawMess Should be passed only if asset and source were not specified.

• *Note:** for Testnet assets, coin_type is always '1'.

type

string

RawMess Should be passed only if operation is TYPED_MESSAGE. Possible values are:

• EIP191: for ETH/EVM personal messages
• EIP712: For ETH/EVM typed messages
• TIP191: For TRX personal messages
• BTC_MESSAGE: For BTC personal messages

preHash

PreHash object

An object to send (described below) when creating ECDSA Raw signing requests in cold wallet workspaces.

Required in Cold Wallet workspaces only. Regular Fireblocks workspaces do not require this object to be sent.

content

string

The pre-hashed content in hexadecimal representation.

hashAlgorithm

string

The hashing algorithm to apply to the provided content.
Possible values:

• SHA256
• KECCAK256
• BLAKE2
• SHA3
• DOUBLE_SHA256
