BIT.SIGN
Blockchain-verified document signing for multi-party agreements, company registers, and treasury governance — every signature inscribed on Bitcoin SV.
Multi-Party Signing
Send documents to multiple signers with ordered workflows and email invitations. Every signature is inscribed on Bitcoin SV as tamper-proof evidence of intent.
Treasury Governance
Multi-signature treasuries (m-of-n) with spend policies, on-chain proposals and voting, statutory members registers (cap tables), and role-encrypted board records.
Identity & KYC
HandCash sign-in plus optional social attestations, Veriff biometric KYC (Level 4 “Sovereign” certificate), and portable $401 on-chain identity certificates.
Public Verification
Anyone can verify a signed document, look up a deed by transaction ID, or inspect a company's cap table — no account required.
