An unconfirmed transaction refers to a blockchain transaction, such as buying, selling, or transferring a cryptocurrency, that has not been permanently recorded on the blockchain.
An unconfirmed transaction status means that the network of miners or validators has not fully examined the entire transaction to determine that there are no pending transactions involving the same cryptocurrency that is being used.
In the event that a cryptocurrency sender removes or reduces transaction fees or does not increase fees on a congested network, miners and validators can simply ignore the transaction.
Once a transaction has remained unconfirmed for a long time, the transaction is not added to a block and may simply be discarded entirely by the network.
