New Product — ProntoSigned

Contracts sealed
to a
verified identity.

ProntoSigned goes beyond e-signatures. Every agreement is anchored to a real, biometrically-confirmed identity and secured with an immutable SHA-256 cryptographic hash.

The security gap

Why legacy e-signatures
aren't enough

Traditional platforms verify the document. They rarely verify the person. That distinction is everything when a dispute reaches a courtroom.

Identity Spoofing

Anyone can type a name into a signature box. Without real-time ID verification, you have no way to confirm the person behind the screen is who they claim to be.

Repudiation Risk

Without a biometric audit trail, signers can credibly claim "that wasn't me" in legal disputes, leaving you with a worthless digital mark and an expensive case.

Document Tampering

Centralised cloud storage with no cryptographic integrity check means an altered document looks identical to the original — until you look too late.

How it works

The ProntoSigned
Triple-Lock Protocol

01

Identity-Bound Signing

Every signer first passes through the ProntoID biometric engine. We perform real-time liveness detection, match the person to their government-issued ID, and bind the resulting verified identity certificate to the contract. The signature is not a scribble — it is a cryptographic assertion tied to a confirmed human being.

02

SHA-256 Cryptographic Hashing

Once all parties have signed, ProntoSigned computes a SHA-256 hash of the complete document — a unique 64-character fingerprint of every byte. If even a single comma is changed after the hash is generated, the fingerprint will no longer match, providing instant mathematical proof of tampering. You do not have to trust the host. The mathematics proves the document is original.

Immutable Audit Trail

Every event in the signing lifecycle — ID scan initiated, liveness passed, biometric match confirmed, document hashed, signature appended — is written to a tamper-evident, time-stamped audit log. This delivers non-repudiation: the legal and technical impossibility of a signer credibly denying their participation.

The maths never lies

A contract that proves
itself

Every ProntoSigned contract carries its own SHA-256 fingerprint. At any point in the future — whether in a boardroom or a courtroom — any party can recompute the hash from the document and compare it against the original seal. No trust in a third-party host required.

Independently Verifiable
The hash is public and recomputable. Your legal team, auditors, or counterparty can verify integrity without logging into any portal.
Zero-Knowledge Privacy
Verification does not require exposing document contents. The hash proves integrity without revealing the underlying data.
Court-Admissible Evidence
The audit trail, biometric records, and hash certificate together form a legally-structured evidence package designed for dispute resolution.

Use cases

Built for high-stakes
agreements

Insurance & Lending

Policy sign-offs and loan agreements are prime targets for identity fraud. ProntoSigned binds each signatory to a biometrically verified identity before a single clause is accepted, eliminating the two most common fraud vectors: impersonation and post-signature document alteration.

Commercial Contracts

Enterprise NDAs, service agreements, and partnership contracts where both parties need verified-identity assurance and cryptographic proof of integrity.

Real Estate & Finance

High-value property transactions and loan agreements demand certainty of identity. ProntoSigned provides a court-admissible identity event for every signatory.

Healthcare Consent

Patient consent forms and treatment authorisations that must withstand audit — with biometric proof the correct patient signed, not a family member or proxy.

Employment & HR

Offer letters, IP assignment agreements, and contractor onboarding — with verified identities archived alongside every signed document from day one.

Cross-Border Agreements

International contracts where counter-party identity can never be assumed. ProntoSigned verifies 190+ country documents before a single signature is appended.

FAQ

Common questions

ProntoSigned is an identity-verified digital contract platform. Unlike legacy e-signature tools that only confirm email access, ProntoSigned requires every signer to pass real-time KYC — biometric liveness detection matched against a government-issued ID — before they can sign. The signed document is then sealed with a SHA-256 cryptographic hash, making any post-signature tampering instantly detectable.

A SHA-256 hash is a unique 64-character digital fingerprint computed from every byte of your document. If even a single character is altered after signing, the hash will no longer match, providing mathematical proof of tampering. You do not have to trust the host — the cryptography proves the document is original.

Non-repudiation means a signer cannot later deny their involvement in a contract. ProntoSigned achieves this by binding each signature to a verified identity event — biometric match, ID scan, liveness check, and timestamped audit log — creating a legally and technically irrefutable record.

Yes. Insurance policy sign-offs, loan agreements, and credit facility documents are among the highest-value use cases for ProntoSigned. Each signatory is biometrically verified against their government-issued ID before signing, and the completed document is sealed with a SHA-256 hash. This eliminates the two fraud vectors most commonly exploited in financial document disputes: identity impersonation and post-signature alteration.

ProntoSigned uses the ProntoID verification engine, which supports passports, national ID cards, and driving licences from 190+ countries. Full MRZ parsing is available for ICAO 9303-compliant documents including EU national IDs, EU driving licences, and international passports.

ProntoVault handles certified cryptographic document delivery and secure storage. ProntoSigned focuses on the identity-verified signing event itself. Together they form a complete end-to-end pipeline: verified signing → cryptographic sealing → certified delivery and secure archival.
