Why LexProof
Audit logs live inside a vendor's database. LexProof's evidence can be checked outside it.
Proof of process
AI findings, the human decision, the published version and its fingerprint are sealed together and timestamped on chain.
Verify without trusting us
Anyone's browser recomputes the fingerprint and reads the public chain directly. No login, no LexProof backend.
Enforced, audited approval
Nothing changes until a different person approves, admins included. Overrides need a written reason and are logged.
Privacy-preserving anchoring
Only 32-byte fingerprints go on chain. Never contract text, never personal data.
Capabilities
One evidence system, from first read to board report
AI contract review
Risk and compliance scoring, plain-English briefs and clause-level findings with recommended fixes.
Human-approved redlines
AI proposes, people decide. Separation of duties and a full decision history on every change.
Legal Passport
One record per contract: risk, findings, decisions, evidence and the on-chain anchor. Exports as an evidence pack; verifies by QR.
Continuous proof monitoring
A Chainlink CRE workflow re-checks stored evidence against the chain on a schedule and flags any mismatch.
