Bitcoin transactions are handled by the blockchain. When you send bitcoin, your transaction is added to a “block,” which is then added to the blockchain. The blockchain is a public ledger that contains all confirmed bitcoin transactions. When you send bitcoin, your transaction is broadcast to the network and added to a block by miners. Once your transaction has been verified and included in a block, it will be considered “confirmed.” However, sometimes transactions can get stuck in an unconfirmed state.

What does unconfirmed transaction mean?
An unconfirmed transaction is a bitcoin transaction that has not been verified and included in a block. When a transaction is stuck in an unconfirmed state, it means that the bitcoins have been sent but the network has not yet verified the transaction.
Why do transactions get stuck in an unconfirmed state?
There are a few reasons why a bitcoin transaction might get stuck in an unconfirmed state. Sometimes, transactions can get stuck because they are low priority and there is not enough space in the next block to include them. In other cases, a transaction might be stuck because it has been flagged as suspicious or contains invalid data.
How do I fix unconfirmed Bitcoin transactions?
The best way to fix unconfirmed bitcoin transactions is by using a RBF or CPFP transaction. Replace-By-Fee (RBF) allows you to alter the fee that was attached to your original transaction so it can be included in the next block mined. Child Pays For Parent (CPFP) involves paying a higher fee for a parent transaction so that its children transactions can be confirmed. If you are unable to use RBF or CPFP, then you might have to wait until the next block is mined before your transaction will be verified and included.
What happens to an unconfirmed transaction?
Unconfirmed transactions will remain in the mempool until it is either confirmed or expired. If a transaction remains unconfirmed for too long, it might be automatically cancelled by the network.
How can I avoid an unconfirmed transaction?
