If the Bitcoin transaction is confirmed, then the cancellation is not possible. However, they are enough for your transaction to be confirmed in the next blocks. Not all miners support CPFP at the moment. If the wallet does not allow the use of unconfirmed change, you can send yourself all the funds that are in the wallet. Thus, for these two transactions, the total commission will be taken into account, on the value of which the speed of inclusion of a bundle of transactions into a block will depend. Some wallets allow you to do this even before the transaction is confirmed. The CPFP function can be used by both the sender and the recipient of funds.Ī new transaction (for example, between your addresses) with a high fee is attached to the expected transaction with a low fee. This change can be spent on the next transaction.
Most transactions not only send BTC to the recipient but also return "change". Speeding up a transaction with Child Pays for Parent Bitcoin wallets Bitcoin core, Electrum and Green Address have such a function. Select a stuck transaction in the wallet history and set a new additional fee.īy activating the RBF option, you inform the networks that you are ready to pay more in the event of a delay, and the new transfer is automatically accepted instead of the old one. If the transaction is not confirmed for a long time, you can increase the payment transfer. For this, for example, the Electrum wallet has an add-on "edit fees manually" and also "replace by fee".īefore sending coins, you need to make sure that the "replaceable" option is enabled in the wallet. During the creation of a transaction, the wallet adds a comment, which indicates the right to change the commission after the transfer is queued for processing. Replace by fee adds a new fee to an existing transaction.
For a transaction to be potentially replaceable, the nSequence must be less than (0xffffffff - 1).īy default, most modern wallets nSequence immediately set the maximum, and the ability to replace transactions must be enabled in the settings. For replacement, a special nSequence field is provided in the transaction data, which signals which transaction is older. It was then modified to RBF and included in Bitcoin Core 0.12 and older. The replacement of transactions was envisaged by the creator of the system, Satoshi Nakamoto, but turned off at a certain moment. Accelerating transactions by increasing fees In the blockchains Bitcoin, Ethereum and others, there is a mechanism that allows you to replace an unconfirmed transaction with another transaction with a higher fee. Such transactions still have the ability to become processed. Unconfirmed transactions most often happen precisely because of the low fees. All operations that were not added to the block after launch are considered unconfirmed. This may be due to the fact that transactions do not enter the block for a long time.
The original transaction can be replaced only if it was made using Electrum with the "Replace by fee" option on (Tools - Preferences - Replace by fee).A situation arises when you want to cancel or replace a transaction. It is possible to use Replace-by-fee with Trezor device in Electrum. The additional fee will then be reallocated from the transaction output.

To speed up confirmation times when sending the full balance of an account, click Bump fee on the pending transaction.Using RBF output reduction can be done in the same way as bumping the fee, as long as RBF was enabled when the transaction was sent. RBF by output reduction takes the additional fee from the amount being transferred, instead of the account balance. When sending the maximum amount of bitcoin stored on a single account, there will be no leftover balance to increase the fee from. Clicking on Finalize transaction in the pending transaction pop-up dialog will send a replacement transaction that is identical but has the RBF flag turned off.
