Legally-Binding Electronic Signatures with Blockchain Proof
The vSign Guarantee™ is our commitment that every electronic signature processed through the Veritize platform meets the highest standards of security, legal validity, and evidentiary integrity.
Unlike basic e-signature services, vSign combines hardware-bound TPM security, RFC 3161 trusted timestamps, and multi-chain blockchain anchoring to create signatures that are not just legally valid — they're cryptographically provable and immutable.
If a signature carries the vSign Guarantee™, it means: The signer's identity was verified, the document was timestamped by a trusted authority, and the signature is permanently recorded on the blockchain.
Signatures are bound to hardware security modules, making them impossible to forge or transfer to another device.
Every signature includes a legally-recognized trusted timestamp proving exactly when the document was signed.
Signature hashes are anchored to multiple blockchains (XRPL, Ethereum, Polygon) for permanent, tamper-proof records.
Multi-factor identity verification ensures the signer is who they claim to be — email, SMS, government ID, or biometric.
Every action is logged: document views, signature events, IP addresses, device fingerprints, and more.
Meets ESIGN, UETA, eIDAS, and international e-signature regulations for cross-border validity.
Upload your document to the Veritize platform. Define signature fields, signers, and the signing order. The document is hashed and a unique identifier (VID) is assigned.
Each signer verifies their identity through the configured method: email link, SMS code, knowledge-based authentication, government ID scan, or biometric verification.
The signer applies their signature. The signing event is bound to their TPM-secured device, creating a hardware attestation that proves the signature came from a specific, verified device.
A trusted timestamp authority issues a cryptographic timestamp proving the exact moment of signing. This timestamp is embedded in the signed document.
The document hash, signature, timestamp, and audit trail are anchored to multiple blockchains. This creates an immutable record that can never be altered or deleted.
All parties receive the signed document with an embedded vSign Guarantee™ certificate containing blockchain transaction IDs, timestamp tokens, and verification QR codes.
Trusted Platform Module creates a hardware root of trust. Keys never leave the secure enclave.
Third-party timestamp authority provides legally-recognized proof of when the signature occurred.
Multi-chain anchoring ensures the record can never be altered, even if the original server is compromised.
Every action is logged with IP, device, geolocation, and timestamp for forensic-grade evidence.
