Sign a demo contract, get the exact completed copy back with a post-quantum (ML-DSA-65) proof anchored on Algorand, and check it yourself. Free, nothing to install.
Enter a name. DocuSign opens a demo agreement for you to sign. No email or account needed.
When you finish, DocuSign Connect notifies the archive. It downloads the completed PDF, hashes it, and anchors the hash on Algorand mainnet (usually within 30 seconds).
You get a private link to your archived copy, its proof bundle and a one-click verifier. Edit one byte and watch it fail.
Your name appears in the document and its proof, which are reachable only through your private link. Only hashes go on-chain. This is a sandbox envelope with a demo watermark, not a binding contract.
2 · Anchor any file (hash only)
Your browser computes the SHA-256 of the file. Only the hash is sent, and nothing is stored. You get back a signed proof bundle anchored on Algorand.
How it works with DocuSign Connect, what the proof does and does not show, and how to run it against your own sandbox: see the README. Verify any receipt in your browser or with the open-source CLI, without trusting this service.
