Blender Wallet Adds One-Click Replace-By-Fee Transaction Cancellation

The Bitcoin wallet Blender Wallet has added the Replace-By-Fee (RBF) feature. It allows users to speed up or cancel an unconfirmed transaction in a single click, according to representatives of the wallet.

Replace-By-Fee operates on the basis of a transaction-priority mechanism:

1. The user sent 1 BTC and set a fee of 0.00001 BTC.
2. Miners did not include the transaction in the next block because they prioritised transfers with higher fees.
3. The user used RBF to accelerate the transaction: another 1 BTC was sent to the same address, this time with a fee of 0.00002 BTC.
4. Miners included the second transaction in the block.
5. The Bitcoin network removed the first transaction from the mempool.

Using RBF, users can also cancel a Bitcoin transfer: Blender Wallet will duplicate the transaction with a higher fee and route it to the sender’s wallet.

Blender Wallet is a non-custodial Bitcoin wallet from the developers of the mixer Blender.io. The wallet supports SegWit addresses, hierarchical-deterministic wallets, and freezing of accounts.

Blender Wallet is suited to crypto investors who value anonymity: they can mix transactions using the mixer and receive bitcoins at clean hierarchical addresses.

Earlier, ForkLog published Blender Wallet review and concluded that cracking the wallet would take 2.9×10^50 years.
