Unconfirmed Transaction Meaning

An unconfirmed transaction refers to a payment or transfer on a blockchain that has been transmitted to the network but has not yet been processed and recorded in a block. Once created, the transaction enters the mempool, where it awaits validation by miners or validators.

Transactions remain unconfirmed until they are included in a block, at which point they receive a confirmation. The time a transaction spends unconfirmed depends on network congestion and the fee attached; higher fees incentivise faster inclusion.

Unconfirmed transactions can be replaced or cancelled by broadcasting a conflicting transaction with a higher fee (Replace-by-Fee), though this is discouraged in many contexts.

Users should wait for sufficient confirmations before assuming that an unconfirmed transaction is final.
