It is built for banks, insurers, real estate firms, government agencies and healthcare organisations that need signatures that are both legally binding and defensible.
Every signer passes a biometric and document check plus a liveness test before signing, so the person approving the document is confirmed to be physically present in real time.
Witnesses join through secure video conferencing, watch the signing live, and confirm it in the moment. Recordings and the full audit trail are stored on blockchain.
The platform generates customisable activity reports that track signing progress, bottlenecks and completion across documents and participants.
Documents are encrypted at rest and in transit with access control and integrity checks, and personal data is not retained longer than verification and execution require.
