Attestra is your contracts, approvals, and signature layer. Drag fields onto any PDF, send to as many signers as the deal needs, capture identity proofs where the law requires, and store the signed document with a tamper-evident audit trail you can hand to any auditor or court.
Legally compliant signatures
Aadhaar e-sign, DSC, OTP, click-wrap, and qualified signatures — recognised across major jurisdictions.
Tamper-evident audit trail
Every signed document is hashed, timestamped, and verifiable by any third party — including the signers themselves.
Workflows, not just signatures
Multi-party, sequential, parallel, and conditional approval flows — with comments, redlines, and version history.
