What is Replace-by-Fee (RBF), and which wallets support it?
Replace-by-Fee (RBF) is a Bitcoin protocol feature that allows users to modify an unconfirmed transaction by increasing its fee, helping it get prioritised by miners. This is useful when a transaction gets stuck due to low fees or network congestion. With RBF, the sender can essentially "replace" the original transaction with a new version that offers a higher fee, improving the chances of faster confirmation.
How RBF Works
A user broadcasts a transaction with RBF enabled.
If the transaction remains unconfirmed, the sender creates a new version with a higher fee.
Miners prioritise the updated transaction, dropping the original one.
Wallets That Support RBF
Electrum (Desktop) – One of the first to implement RBF.
Wasabi Wallet (Privacy-focused) – Supports RBF for better transaction flexibility.
Samourai Wallet (Mobile) – Offers RBF and other advanced Bitcoin tools.
Bitcoin Core (Full node wallet) – Allows manual RBF through its console.
BlueWallet (Mobile/Lightning) – Supports RBF for on-chain transactions.
Limitations & Risks
Not all wallets support RBF (e.g., many exchange wallets don’t).
Some merchants may reject RBF-enabled transactions due to double-spend risks.
RBF is a powerful tool for optimising Bitcoin transactions, especially during high-fee periods. Always check if your wallet supports it before relying on it.
