Speed up transaction

This operation accelerates a specified transaction.

Speeding up a transaction will trigger a Replace-By-Fee (RBF) transaction which is a new version of the original transaction. It shares the same inputs but must have a higher transaction fee to incentivize miners to prioritize its confirmation over the previous one. A transaction can be accelerated if its status is Broadcasting.

You can use the address or included_utxos properties in the request body to specify the address or UTXOs that will cover the transaction fee. Generally, the transaction fee is paid by the original transaction’s source. If that source’s balance is insufficient, the specified address or UTXOs can be used to cover the fee.

A transaction request for tracking is returned upon successful operation.

This operation only applies to transactions from MPC Wallets and Smart Contract Wallets. It does not apply to transactions on the following chains: VET, TRON, TVET, SOL, and TON.

If you speed up a transaction from a Smart Contract Wallet, two RBF transactions will be triggered, one for the transaction from the Smart Contract Wallet, and the other for the transaction from the Delegate.
