Sign confidential documents the server never sees — mutual selfie attestation, Bitcoin-anchored, verifiable offline. During Private Alpha, starting ceremonies is reserved for members we onboard a few at a time — the waitlist is how you raise your hand.
Open to everyone, right now — no account, no waitlist: sign any ceremony you're invited to, and verify any COSigna proof, online or offline.
During Private Alpha, starting your own ceremonies additionally needs an invitation — join the waitlist below and we'll reach out as spots open.
