A TXID is a transaction identifier (hash) that uniquely references a Bitcoin transaction on the blockchain.

What do confirmations mean?

Each new block added after your transaction confirms it further. More confirmations generally mean higher finality.

Why does a transaction show as unconfirmed?

It may still be in the mempool waiting for miners, often due to low fees or network congestion.

For typical transactions, the TXID is fixed once broadcast. Some unconfirmed transactions can be replaced (RBF) before confirmation, creating a new TXID.

What this tool is for

Look up a Bitcoin transaction by TXID and see its status, confirmations, inputs/outputs, and fee details. Useful when verifying a payment, debugging “where’s my BTC?”, or checking whether a transaction was replaced.

Examples

Confirm a payment: check confirmations and output address
Spot low-fee delays: compare fee rate to current mempool conditions
Check RBF: if a transaction was replaced, the replacement will have a different TXID
