[ SHA-256 IN YOUR BROWSER · NOTHING UPLOADED ]

Every answercomes back sealed

Signet stamps a fingerprint on work an agent did, signs the stamp with a key you can pin, and hands you one line of text. Anyone can check that line without asking us anything.

Those 64 characters are the SHA-256 of the sentence sitting in the field above. Change one letter and every one of them changes. That line, not your text, is what gets signed.

The Signet receipt is built from SHA-256, secp256k1 over EIP-191, a canonical JSON payload and hash-chained heads.
Film 01 · What a receipt is
Content goes in, a digest comes out, the seal lands on the digest and a key signs it. Watch it once instead of reading the next three paragraphs.
[ The artifact ]

One line, andeverything it proves

A receipt records that something existed in this exact shape at this moment, and that one key vouched for it.

No field for your contentThose bytes never reach us, so no schema here has a place to put them.
Readable before you signThe wallet shows the product name, the digest and the time in the clear.
Ten fields, all computableNothing decorative, and nothing the page cannot work out for itself.

What a good checklooks like

The first film shows a signature holding and a tampered one walking away. The second shows why a run breaks the moment somebody edits the middle of it.

Film 02 · Checking a signature
A good signature and a tampered one, side by side. The second changes one character and the recovered address walks away from the named one.
Film 03 · Why a chain holds
Receipts fold into a run. Rewriting the second one leaves every head after it wrong, which you watch happen rather than take on faith.

There is no presale, no whitelist and no allocation round. When an address exists it appears on the token page first, and every other channel repeats it afterwards. Anyone offering you early access before then is selling you something else.

in the next minute

You need a wallet and a sentence. The page does the rest in front of you, and you can close the tab afterwards with a receipt that still checks out.

Any length in, one length outsha-256

Whatever an agent produced goes in on the left. What comes out is always the same sixty-four characters, and that is what gets signed — never the work itself.
