# Bump Fee

> Speed up a pending transaction on Finrock by resubmitting it with a higher network fee rate. Pass the txn_id and a new fee_rate in chain-specific units.

**[MCP scope](https://apidocs.finrock.io/api-reference/mcp-scopes.md):** `dac.funds` (not available to AI connectors yet)

The Bump Fee endpoint raises the network fee of a transaction that is still pending, so it confirms faster. Pass the transaction's `txn_id` and a new, higher `fee_rate`. To pick a rate, check current conditions with [Network Fee Rates](https://apidocs.finrock.io/api-reference/gas/network-fee-rates.md).

## Body Parameters

**txn\_id** `string` *required*

The Finrock ID of the pending transaction to speed up, as returned by [Create Transaction](https://apidocs.finrock.io/api-reference/transactions/create-transaction.md) or [List Transactions](https://apidocs.finrock.io/api-reference/transactions/list-transactions.md).

**fee\_rate** `float` *required*

The new fee rate, in the unit for the transaction's blockchain (for example, Sat/Byte for BTC or GWei for ETH). See [Gas Fees](https://apidocs.finrock.io/reference/gas-fees.md) for the unit of each blockchain.
