Only transactions with the status 401, 402, and 403 are eligible to be replaced.
Once a transaction (the original transaction or the new transaction) on the chain reaches the required number of confirmations (transaction status changes to 900), other RBF-related transactions will be marked as replaced (transaction status changes to 901).

Request

String

required

Unique transaction ID

String

required

RBF transaction request ID (unique identifier of a transaction request, which must correspond to a client’s transaction; UUID should be used and the length should be equal to or less than 120 characters)

Float

Transaction fees per byte; must be higher than the original transaction fees; applicable to the UTXO model

Int

Gas price; must be higher than the original gas price

Int

Gas limit

Int

transaction fee; applicable to UTXO model; use either fee or fee_amount for UTXO model

Int

How the transaction utilizes the gas station, 0: no refueling(default); 1: passive use of the gas station; 2: active use of the gas station.
This parameter is used when you’ve activated the gas station service and use the gas station to support the transaction fee for MPC transactions.

The gas station will definitely refuel for the transaction when in active use, while for passive use, refueling by the gas station occurs only when the address balance is insufficient for transaction fees.

String

UTXO Model:

utxo_from_address: Given that the new transaction fee is higher, if the new transaction requires additional inputs, then the new inputs will be selected from utxo_from_address. Please note that the new inputs will be selected from the current wallet if this parameter is not provided.

Sample

extra_parameters: '{"utxo_from_address": "tb1qpllcnnpt3z9nkxtj3a0jmhdj5xvxaerhv5xs5n"}'
