# Speed up transaction

> This operation accelerates a broadcasting transaction by submitting a Replace-By-Fee (RBF) transaction with higher fees.

The transaction must be in `broadcasting` status. You must supply the `fee` field with higher fee parameters than the original transaction.

Provide `cobo_transaction_id` in the request body to identify the transaction by its provider-assigned ID instead of the local UUID in the path.

<Note>RBF speedup is not supported on VET, TRON, TVET, SOL, TON chains or gasless (paymaster) transactions.</Note>
