![]() ![]() This will also allow transactions to be replaced even if they are not explicitly marked as replaceable, deemed full RBF. The wallet allows users to set their node forward, even conflicting transactions with higher charges. The discussion is technical, but it is manageably complicated. It was about the planned release of Bitcoin Core 24.0 and the “Full RBF” introduced by it. Here are some wallets that support RBF: Bitcoin CoreĪn exciting discussion ran through the Bitcoin mailing list throughout October of last year. Knowing the wallets that support RBF can be of utmost importance. With an increasing number of transactions in the wait, fee bumping will become a bigger deal. ![]() Wallets that Support Replace-by-Fee for Bitcoin So an occasional discussion topic is proposals to allow RBF to operate solely on a feerate basis. This can make multiparty transactions that want to use RBF vulnerable to transaction pinning attacks. Another alternative RBF variant is full RBF, which permits the replacement of any transaction, regardless of whether it signals BIP125 replaceability.īIP125 requires a replacement transaction to pay a higher feerate (BTC/vbyte) and a higher absolute fee (total BTC). The current RBF is the BIP125 opt-in RBF, which enables the transaction originator to indicate their willingness to permit it to be substituted with a higher-paying version. Various node software implementations employ diverse RBF rules, resulting in multiple variations. Replace-By-Fee (RBF) is a node policy that allows an unconfirmed transaction in a mempool to be replaced with a different transaction that spends at least one of the same inputs and pays a higher transaction fee. As such, replace-by-fee (RBF) wallets come into play. The ability to bump up the transaction fee on a specific transaction helps in rescuing a time-sensitive transaction or as a strategy to pay less in fees. ![]() Transactions with inadequate fees wait in the mempool for higher-paying ones to clear. Transaction inclusion in the next block is determined by offered transaction fees. Since 2020, Bitcoin transactions have often exceeded available block space. ![]()
