Chaindoc

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

Chaindoc is an agreement management platform that combines e-signature, built-in KYC identity verification, and contract-based payments in a single workflow. Every signed document is sealed with a SHA-256 hash on the blockchain, creating a tamper-evident audit trail. It offers templates, multi-party signing, role-based permissions, and REST API/webhook integration for embedding into existing systems.
