Sign agreements, verify identities, and collect payments — in one place.

E-signature platform with built-in KYC and payments. eIDAS-compliant. Blockchain audit trail on every signature.


What is Chaindoc?

An agreement management platform — not just an e-signature tool.

Chaindoc combines e-signature, built-in KYC identity verification, and contract payments in one workflow. You sign a contract, your client verifies who they are, then pays — without bouncing between three tools.

Signatures are eIDAS- and ESIGN-compliant, ISO 27001 and CSA STAR certified. Every signed document gets a SHA-256 hash on the blockchain. Anyone can verify — including the courts.
