Check a receipt.

When a waiver is signed, WaiverDrop records exactly what the signer agreed to — their details, the text of the waiver itself, and the signature they drew — and seals it with an Ed25519 digital signature. The receipt is that sealed record.

The public half of our signing key is published at /.well-known/waiverdrop-keys.json. Anyone can fetch it and check a receipt themselves, with no involvement from us — this page is a convenience, not the authority.

What the signature proves: that the record in the receipt has not been altered since it was signed. On its own it does not prove when the record existed — WaiverDrop holds the signing key, so a dishonest operator could in principle sign a record after the fact.

That is what the timestamp is for. A receipt can also carry a signature from an independent Time-Stamp Authority — a third party who attests that a record existed at a given moment and never sees the data itself. Nobody can obtain a timestamp dated in the past, so a record that carries one could not have been written later. The verdict above says whether this receipt has one and whether it checks out; a receipt without one still proves what was signed.
