Sign contracts with AI-powered intelligence. Every document is cryptographically sealed with permanent, tamper-proof verification — creating an immutable, independently verifiable proof of signing.
Draft or upload a document. Add signers. Each signs with draw, type, or biometric authentication.
The signed document is hashed using SHA-256 — a one-way cryptographic fingerprint unique to that exact file.
The hash is permanently anchored on a public, decentralized ledger — immutable and independently accessible by anyone.
Anyone can verify the document hasn't been altered by comparing its hash against the permanent public record.
Full Tiptap-powered editor with headings, lists, tables, highlights, and template variables. Or upload any PDF and place signature fields with a drag-and-drop editor.
Route documents through multiple signers in order, or let everyone sign simultaneously. Each signer gets a unique, secure signing link via email or WhatsApp.
Signers can authenticate using Face ID, Touch ID, or Windows Hello — the same passkey technology used by banks. No passwords, no friction.
Optional 10-second video recording during signing captures the signer on camera. The video is hashed and included in the audit trail for disputes.
Record the exact signing location with GPS coordinates. Reverse-geocoded to city/country for human-readable audit records. Optional per agreement.
Smart escalation: gentle reminder at 24 hours, follow-up at 3 days, firm notice at 7 days. Tone adapts automatically. Cap at 3 reminders per signer.
Auto-generated PDF certificate with all signer details, timestamps, IP addresses, signature hashes, verification transaction ID, and QR code linking to public verification.
Anyone can verify a document at nijam.co/verify — enter the agreement ID or document hash. Three-layer check: hash match, permanent anchor, signer verification.
Traditional e-signatures rely on the platform's database as proof. If the company shuts down or data is compromised, your proof disappears. Independent verification changes that.
Once sealed, the hash can never be altered or deleted. Even if Nijam ceases to exist, the cryptographic proof persists forever on a public ledger.
Anyone can verify a document independently — no dependency on Nijam's servers. True zero-trust verification using public blockchain explorers.
Change a single pixel in the PDF, and the SHA-256 hash changes completely. Instant detection of any modification, no matter how small.
