Any proof type
Attestations, approvals, deliveries, model decisions, consent records — you define the type and payload.
Universal Proof & Verifier
Mint portable proofs. Verify them anywhere, deterministically.
Universal Proof turns any statement — a completed KYC check, a signed invoice, a model output, a shipment handover — into a signed, hashed, portable artefact. The Universal Verifier checks any proof deterministically and returns machine-readable evidence you can hand to an auditor or a counterparty without exposing the underlying data.
Built for: Fintech, marketplace, supply-chain and compliance teams that must prove events to third parties.
Capabilities
Deterministic verification
The same proof always yields the same verdict, with the reason recorded rather than inferred.
Portable by design
Proofs travel as self-contained artefacts. Your counterparty verifies without access to your database.
Hash-chained evidence
Every issuance and verification is appended to an evidence chain, so tampering is detectable.
What you get out of it
- Answer 'prove it' requests in seconds instead of weeks
- Give auditors a verifiable trail instead of exported spreadsheets
- Share verification with partners without sharing raw records
Try it right here
This runs the real logic on our servers — no account, no canned responses. Demo runs are not stored and use a published demo signing key; your tenant uses rotating ML-KEM-1024 material.
Mint a proof
Turn a statement into a portable artefact. The payload is canonicalised, hashed with SHA-256 and signed with a real ECDSA P-256 key on the server.
Verify it — or break it
The verifier recomputes the hash and checks the signature. Edit a single character in the artefact, or press “Tamper”, and verification fails with the reason recorded.
How it fits the platform
Universal Proof sits directly on top of Trust Kernel: identities sign, proofs carry the claim, and the verifier gives your counterparties a way to check it without touching your systems.

Universal Proof & Verifier is included from the Starter plan at $49 / month, with every higher plan including it too. Verification is never charged per check — plans differ on volume, retention, autonomy and governance.
