Bitcoin developers want to fix the 'replace this transaction with a higher fee' button. Here's why
CoinDesk 2026-06-22 06:19:13
Context: Bitcoin developers are seeking to remove a feature called explicit replace-by-fee (RBF) signaling from wallet software, as it has become redundant and a potential privacy issue. This feature, which allows users to signal that they might want to replace a transaction with a higher fee, was once useful for speeding up transactions but is now unnecessary since the network handles transaction replacements automatically. Developers are coordinating on a common default input sequence number to make transactions from different wallets look similar and harder to track.
Key Facts
- Bitcoin developers want to remove explicit replace-by-fee (RBF) signaling from wallet software because full-RBF is now standard policy, making the old opt-in flag redundant.
- The explicit "replace later" signaling in Bitcoin wallets has become redundant and leaves unnecessary digital fingerprints of the wallet involved in the transaction, potentially revealing which wallet software was used.
- Developer rkrux posted to the developer-mailing list that the primary reason for removing RBF signaling is that it has become redundant since full-RBF became a standard policy.
- Removing the signal requires careful planning, as different wallets deleting this replace function in different ways would make transactions processed through these wallets look distinct on-chain and easy to track.
- Community participant Murch noted that since about 75% of transactions are already using one specific code, mostly MAX-2, the best way to hide is to join them rather than trying differently and stand out.
