Wallets Which Support Replace-By-Fee (RBF) Fee Bumping
[Last Updated: 16 August 2023.]
[2023–08–16: Full-RBF effectively has arrived. What this means is that even if you used a wallet that did not support RBF, or did not have it enabled when you created your transaction, …. as long as you have the keys you can still do RBF on that transaction. More on this coming soon.]
Beginning from the year 2020 there have been numerous extended periods of time that bitcoin transaction activity will exceed the supply of space in new blocks on the Bitcoin blockchain.
Transactions compete to be included in the next block solved by a miner based on the amount of the Bitcoin network transaction fee that the transaction offers to pay. Transactions whose transaction fee offer isn’t competitive enough will sit in the mempool, waiting for miners to clear out the transactions that had paid a higher fee.
Being able to bump up the transaction fee on a transaction is useful to help rescue a time-sensitive transaction, or as a strategy to pay less in fees. If your wallet supports replace-by-fee (RBF), and that support is enabled for a transaction, you can feel comfortable choosing the lower-end of the transaction fee range. If the transaction doesn’t confirm soon enough for you, you can simply bump the fee later using RBF.
The wallets with RBF support (that I know of):
- Bitcoin Core has RBF support, including in the GUI (where an unconfirmed transaction offers the option to select “Increase transaction fee”).
- Blockstream Green has RBF support built-in now
- Electrum lets you right click, and then increase the fee, which uses RBF. There’s also a “Cancel” transaction, which uses RBF (as-of Electrum v4.0.4).
- Samourai Wallet (Android) (enabled in Settings > Transactions menu)
- BlueWallet has RBF support implemented as “Bump Fee” and “Cancel Transaction”
- Specter Wallet has RBF support
- Sparrow Wallet has RBF support
- NBD’s OBW has RBF support (as did the abandoned SBW / Simple Bitcoin Wallet from which OBW had forked)
- Peach now has RBF support.
- Coinb.in will let you create a transaction with RBF enabled and separately will let you create a replacement transaction. [Caution: This is a powerful, low-level tool and it lets you make a mistake that could result in you losing your funds.]
- ConIO has RBF support
- Nunchuk (Beta) has RBF support
- Mercury Wallet (for Mercury statechain) has RBF support (since v0.6.5)
- Fully Noded has RBF support
- Armory, reportedly does, per a comment reply to an r/Bitcoin post
- Blixt Wallet RBF Support is planned
- Wasabi Wallet does signal for RBF support but to create a replacement transaction for would require another wallet
- Founder of Hodl Wallet had tweeted that RBF was “on the roadmap”

Further information:
- Blockstream’s Bitcoin Explorer where you can find additional information about your transaction, including the fee offered (sats/vByte)
- Mempool / fee estimation sites: Mempool.space, Johoe’s Bitcoin Mempool Statistics, Bitcoiner.Live Fee, and BitcoinFees.net
- Bitcoin Optech’s RBF in the Wild article
- Chart — Transactions Using RBF. Just because you are using a wallet with RBF support doesn’t mean your transactions are marked as replaceable. Only when the transaction is marked as replaceable when first sent can a replacement transaction be relayed later. As-of March, 2021 only about 17% of Bitcoin transactions are marked as replaceable. [Update: As the New Year 2022 arrived, that metric was closing in on 30%.]
