What is RBF (Replace-By-Fee)?

Replace-By-Fee (RBF) is a Bitcoin feature typically utilized during periods of high network congestion and fluctuating fee rates. It allows users to increase the probability of their transaction being confirmed on the blockchain by replacing a stuck, unconfirmed transaction with a new one that includes a higher fee. This rebroadcasting ensures miners are more likely to pick up the transaction.

What are the risks?

BitPay Invoices are protected against double-spending or the transaction being replaced. One blockchain confirmation is required before the invoice is marked as paid. RBF can be used on BitPay Invoices transaction if they get stuck.

When receiving a peer-to-peer (P2P) Bitcoin transaction, it is essential to wait for blockchain confirmation to guarantee the funds are successfully deposited into your wallet. After confirmation, the transaction is irreversible. You can check the status of your transaction using any blockchain explorer or BitPay Insight.

How can I use RBF with the BitPay Wallet?

To speed up an unconfirmed Bitcoin transaction, select the transaction in your wallet to access the Replace-by-Fee (RBF) option. Note that using the RBF feature requires you to have additional confirmed Bitcoin in your wallet.
