What did my transaction pay?

Paste a signature. The page splits the fee into base and priority fee, compares the compute units used with the limit, and shows the part of the priority fee paid for units the transaction never used.

Transaction signature

Read from a public Solana node through the site’s data service. Nothing is stored.

FAQ

Where do I find the transaction signature?

In your wallet's activity view (often called transaction ID or hash) or in any block explorer. It is a base58 string of about 88 characters.

Why did I pay for compute units I did not use?

The priority fee is charged on the compute-unit limit, not on the units consumed. A transaction that sets a 1,400,000 limit and uses 200,000 pays the price on all 1,400,000.

My transaction failed. Did it cost anything?

If it is found here, it landed: the full fee was charged even though its instructions failed. A transaction that never landed cannot be found and cost nothing.
