Accelerate Transaction - UTXO RBF

Accelerate a stuck UTXO transaction using Replace-By-Fee (RBF). See the Guide.

Accelerate a stuck UTXO transaction using Replace-By-Fee (RBF). RBF transactions include a higher fee and replace the lower-fee stuck transaction in the mempool. BitGo recommends accelerating using RBF and by default enables RBF for all transactions created in the BitGo web application.

You must ensure your initial transaction was built with isReplaceableByFee set to true. Provide the stuck transaction ID in rbfTxIds and set feeMultiplier to increase the fee.

Prerequisites: Complete Get Started and ensure the original transaction was built with RBF enabled (see Withdraw Overview).
