Verify a stamp
Paste a transaction hash or a certificate URL/payment ID. We
re-read the Stamped event straight from a public
blockchain node and show you what we found. No account, no app,
no trust in us.
Recently verified
Stored in this browser only — these are stamps you verified yourself.
The contract address and the on-chain ABI are open source. If you
don't trust this page, copy the transaction hash and run the
eth_getTransactionReceipt RPC call yourself, or read
the logs on
BaseScan.
