Event Objects

id

string

The ID of the transaction.

externalTxId

string

Unique transaction ID provided by the user. Fireblocks highly recommends setting an externalTxId for every transaction created, to avoid submitting the same transaction twice.

status

TransactionStatus

The current primary status of the transaction. See Primary Transaction Statuses for a detailed list.

subStatus

txHash

string

The hash of this transaction on the blockchain. txHash is only returned for crypto assets (not fiat) when the operation type is not RAW or TYPED_MESSAGE.

This parameter exists if at least one of the following conditions is met:

1. The transaction’s source type is UNKNOWN, WHITELISTED_ADDRESS, ONE_TIME_ADDRESS, FIAT or GAS_STATION.

2. The transaction’s source type is VAULT and the status is: CONFIRMING, COMPLETED, or was either status prior to changing to FAILED or REJECTED. In some instances, transactions with the status BROADCASTING will include the txHash as well.

3. The transaction’s source type is EXCHANGE and the transaction’s destination type is VAULT, and the status is: CONFIRMING, COMPLETED, or was either status prior to changing to FAILED.

Notes:

For Multi-destination transactions, this parameter will be empty and you should refer to the destinations field instead.

feeCurrency

string

The asset type used to pay the fee (ETH for ERC-20 tokens, BTC for Omni, XLM for Stellar tokens, etc.)

networkRecords

Array of NetworkRecord objects

A transaction in Fireblocks can aggregate several blockchain transactions, typically as part of a contract call. Network records specify all intermediate transactions that took place on the blockchain. For single transactions, this parameter is empty.

createdAt

replacedTxHash

string

The hash of the replaced transaction, only If this is an RBF transaction on an EVM blockchain. Learn more about RBF transactions.

extraParameters

JSON object

Additional protocol / operation specific key-value parameters.

For UTXO-based blockchain input selection, use the inputsSelection field with values set to the input selection structure. The inputs can be retrieved using the Retrieve Unspent Inputs endpoint.

For RAW operations, use the rawMessageData field with the values set to the raw message data structure.

For CONTRACT_CALL operations, use the contractCallData field with the value set to the Ethereum smart contract Application Binary Interface (ABI) payload. The Fireblocks development libraries are recommended for building contract call transactions.

signedMessages

| Parameter | Type | Description
Not all operations are available in all workspaces. Contact your account manager to enable additional features.

TRANSFER - Default. Transfers funds from one account to another. UTXO blockchains allow multi-input and multi-output transfers. All other blockchains allow transfers with one source address and one destination address.

MINT - Mints new tokens. Supported for Stellar, Ripple, and EVM-based blockchains. Learn more about tokenization on Fireblocks.

BURN - Burns tokens. Supported for Stellar, Ripple, and EVM-based blockchains. Learn more about tokenization on Fireblocks.

CONTRACT_CALL - Calls a smart contract method for web3 operations on any EVM blockchain. The Fireblocks development libraries are recommended for building contract call transactions.

TYPED_MESSAGE - An off-chain message in either Ethereum Personal Message or EIP712 format. Use it to sign specific readable messages that are not actual transactions. Learn more about typed messages.

RAW - An off-chain message with no predefined format. Use it to sign any message with your private key, including protocols such as blockchains and custom transaction types that are not natively supported by Fireblocks. Learn more about raw signing transactions.

ENABLE_ASSET - Algorand, DigitalBits, Solana, and Stellar require an on-chain transaction to create an asset wallet and enable the deposit address. This transaction is automatically created when adding assets on these blockchains to a vault account.

STAKE - Assign assets to a staking pool managed by a staking validator. Learn more about staking transactions and supported blockchains. This transaction is automatically created when performing staking operations.

UNSTAKE - Remove assets from a staking pool managed by a staking validator. Learn more about staking transactions and supported blockchains.This transaction is automatically created when performing staking operations.

WITHDRAW - Transfer assets from a dedicated staking vault account to another address. Learn more about staking transactions and supported blockchains.This transaction is automatically created when performing staking operations.

• *Note:** Fireblocks may rename this type from WITHDRAW to a different name soon. There will be at minimum a 7-day notice regarding the new type name.
