Fields

operation: Option<TransactionOperation>

note: Option<String>

Custom note, not sent to the blockchain, to describe the transaction at your Fireblocks workspace.

external_tx_id: Option<String>

This parameter will become required for the Create a new transaction endpoint on March 1, 2026. This parameter allows you to add a unique ID of your own to help prevent duplicate transactions. No specific format is required for this parameter. After you submit a transaction with an external ID, Fireblocks will automatically reject all future transactions with the same ID. Using an external ID primarily helps in situations where, even though a submitted transaction responds with an error due to an internet outage, the transaction was still sent to and processed on the blockchain. Use the Get a specific transaction by external transaction ID to validate whether these transactions have been processed.

asset_id: Option<String>

The ID of the asset to transfer; used for TRANSFER, MINT, or BURN operations. See the list of supported assets and their IDs.

source: Option<SourceTransferPeerPath>

destination: Option<DestinationTransferPeerPath>

destinations: Option<Vec<TransactionRequestDestination>>

For UTXO based blockchains, you can send a single transaction to multiple destinations.

amount: Option<TransactionRequestAmount>

treat_as_gross_amount: Option<bool>

"When set to true, the fee will be deducted from the requested amount." Note: This parameter can only be considered if a transaction’s asset is a base asset, such as ETH or MATIC. If the asset can’t be used for transaction fees, like USDC, this parameter is ignored and the fee is deducted from the relevant base asset wallet in the source account.

force_sweep: Option<bool>

For Polkadot, TON, Kusama and Westend transactions only. When set to true, Fireblocks will empty the asset wallet. Note: If set to true when the source account is exactly 1 DOT, the transaction will fail. Any amount more or less than 1 DOT succeeds. This is a Polkadot blockchain limitation.

fee_level: Option<FeeLevel>

For UTXO or EVM-based blockchains only. Defines the blockchain fee level which will be payed for the transaction. Alternatively, specific fee estimation parameters exist below.

fee: Option<TransactionRequestFee>

priority_fee: Option<TransactionRequestPriorityFee>

fail_on_low_fee: Option<bool>

When set to true, in case the current MEDIUM fee level is higher than the one specified in the transaction, the transaction will fail to avoid getting stuck with no confirmations.

max_fee: Option<String>

The maximum fee (gas price or fee per byte) that should be paid for the transaction. In case the current value of the requested feeLevel is higher than this requested maximum fee. Represented by a numeric string for more precision.

gas_limit: Option<TransactionRequestGasLimit>

gas_price: Option<TransactionRequestGasPrice>

network_fee: Option<TransactionRequestNetworkFee>

replace_tx_by_hash: Option<String>

For EVM-based blockchains only. Notes: - To replace a transaction, create another transaction using the stuck transaction’s hash and specify a higher fee. - To drop a transaction, create another transaction using the stuck transaction’s hash and change the amount field to 0.

extra_parameters: Option<ExtraParameters>

customer_ref_id: Option<String>

The ID for AML providers to associate the owner of funds with transactions.

travel_rule_message: Option<TravelRuleCreateTransactionRequest>

auto_staking: Option<bool>

This feature is no longer supported.

network_staking: Option<TransactionRequestNetworkStaking>

cpu_staking: Option<TransactionRequestNetworkStaking>

use_gasless: Option<bool>

• Override the default gasless configuration by sending true\false

Implementations

impl TransactionRequest

pub fn new() -> TransactionRequest

Trait Implementations

impl Clone for TransactionRequest

fn clone(&self) -> TransactionRequest

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TransactionRequest

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for TransactionRequest

fn default() -> TransactionRequest

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TransactionRequest

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TransactionRequest

fn eq(&self, other: &TransactionRequest) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

where __S: Serializer,

Serialize this value into the given Serde serializer.
