There are two primary strategies you can use to try to cancel your unconfirmed Bitcoin transaction:. Some wallets support the RBF protocol allowing you to replace your original transaction with a new one that includes a higher transaction fee. This would effectively unstick your transaction. To do this, make a new transaction equal to the amount of the original one and send it to yourself.
Make sure the transaction fee on this is significantly higher than the original one you paid. You may need to use another wallet or specialized software that allows double spending for the transaction to be broadcast to the network. If all goes well, miners will pick up the new transaction, and your Bitcoin will be back in your wallet. Hopefully, one of these two methods works for you.

Every confirmed bitcoin transaction is irreversible. But is it possible to cancel unconfirmed bitcoin transactions? An unconfirmed bitcoin transaction occurs when a given transaction fails to receive a confirmation on the blockchain within 24 hours. All bitcoin transactions must be confirmed by miners. They need a minimum of three confirmations to be considered fully confirmed.
There are two main reasons your bitcoin transaction may end up remaining unconfirmed. If you choose too minimal a transaction fee, it may not get confirmed by miners. Make absolutely sure that your transaction is unconfirmed before taking action.
To start with, that means waiting for at least 24 hours. Simply enter your transaction ID and track it through the block explorer. Remember that transactions need a minimum of three confirmations before they are fully confirmed. If you see that your transaction has one or two confirmations, you will have no choice but to wait until it is validated by a third miner. The process has already begun. If there are zero confirmations, you can go ahead and cancel the transaction.
There are two ways of going about this:. The RBF Protocol allows you to broadcast your bitcoin transaction to the network a second time with a higher fee to ensure that it gets picked up by miners. It's normally not easy to do this. Network nodes won't accept transactions which double-spend coins used in a transaction they already know about. However, nodes gradually forget about transactions if they don't get into blocks, so a transaction could be cancelled if it doesn't make it into a block after several days and both the sender and recipient stop rebroadcasting it.
Bitcoin used to have a feature called transaction replacement. A transaction could be marked as non-final, which prevented this transaction from getting into a block, but allowed the transaction to be cancelled at any time.
Satoshi disabled this a while ago, though. Transactions can still be marked as non-final, but they can't be replaced. Sign up to join this community.

What's the point of marking a transaction non-final, then?
A lot of what's at en. DanielH It should be possible to communicate non-final transactions privately and only broadcast the final version of the transaction. Currently, though, one of the parties can publicly broadcast a non-final transaction, and this non-final transaction can't be replaced by a later version of the transaction. This causes problems for some contracts. Nodes should probably just reject non-final transactions if they're not going to allow replacements.
At present, for practical purposes, it's impossible to do this. In theory, miners should be happy to replace a transaction with a conflicting transaction with a higher fee. But to my knowledge, nobody implements this.
