How to check a Kaspa transaction

Paste a transaction ID to see whether it is in the mempool or in a block, which chain block accepted it, how many confirmations it has, and its inputs and outputs.

Quick answer

Paste the 64-character transaction ID into the search box. "In the mempool" means it was sent and waits for a block, usually under a second. "In a block" shows the block, the chain block that accepted it and the live confirmation count.

Pruned node

Looking up an older transaction

Our node is pruned: it keeps about the last 36 hours of blocks and transactions, then drops the oldest. That is how a Kaspa node works by default; keeping everything takes a separate archival setting. For a transaction older than that the page says so, instead of pretending it doesn't exist. Balances and unspent outputs of every address are always current, because the node keeps the full set of unspent outputs.

Never paste a seed phrase or private key into any website, including an explorer. Nobody needs it to look anything up.
Addresses

Kaspa address lookup

Search a kaspa: address to see its current balance, how many unspent outputs it has and the newest of them, plus any payments to or from it still waiting in the mempool. GhostSwap sends KAS payouts to the kaspa: address you enter, so a payout shows on that address's page as a new unspent output, and its transaction page shows the confirmations.

FAQ

Kaspa transaction FAQ

How long does a Kaspa transaction take?

Kaspa makes about 10 blocks a second, so a transaction is usually in a block within a second or two of being sent, and accepted by the chain right after. Exchanges and wallets may wait for more confirmations before they credit it.

What are confirmations on Kaspa?

The number of blocks (counted by blue score) added on top of the chain block that accepted your transaction. At about 10 a second, confirmations climb quickly.

Why does it say our node doesn't hold my transaction?

Our node is pruned: it keeps about the last 36 hours of blocks and transactions, so an older transaction can't be looked up here, and the ID may be mistyped. After a restart the explorer re-reads earlier blocks into its search, which can take up to two hours. If you sent it just now, wait a few seconds and search again. The receiving address's balance and unspent outputs are always current.

Can I see the history of a Kaspa address?

Not on this explorer: our node keeps each address's current balance and unspent outputs (its UTXO index), not a list of past payments. Your wallet keeps your own history.

Where do I find my transaction ID?

In your wallet history, open the transaction: the ID is a 64-character string. When you swap on GhostSwap, the order page shows the payout transaction ID.
