What is Unconfirmed Transaction?

Crypto Glossary Definition

A transaction that has not yet been included on a block, so it is still in a pending state.

Why Unconfirmed Transaction Matters

An unconfirmed transaction has been broadcast to the network but not yet included in a block — it sits in the mempool until a miner/validator picks it up, which can take longer (or require a higher fee) during network congestion.
