Interactive prototype. This is an illustrative Wire Proof interface with sample data — the compliance verdicts and receipts demonstrate the flow, not a live cryptographic engine. It produces the portable H33-74 evidence you can verify independently.

▾ Why withheld?

These fields are not required by the receiving bank for settlement under current EU Transfer of Funds Regulation (TFR) or FATF Travel Rule guidelines. Wire Proof validates each field locally and transmits only a cryptographic proof that the field meets compliance requirements — the actual data never leaves the originator's environment. The receiving bank can independently verify each proof without accessing the underlying value.

Traditional Wire (SWIFT MT103)

✕ 47 data fields transmitted in plaintext

✕ Full account numbers exposed to intermediaries

✕ Beneficiary details visible at every hop

✕ Manual compliance review (4-8 hours)

✕ No cryptographic proof of validation

✕ Compliance evidence = screenshots + emails

Wire Proof (H33)

✓ 5 fields disclosed, remainder proven

✓ Accounts validated without exposure

✓ Beneficiary proven, not transmitted

✓ Automated validation, timed on the run you perform

✓ Triple-signed cryptographic receipt

✓ Machine-verifiable compliance proof

47 → 5 fields

89% data reduction. Same compliance outcome.

Try to break it

Alter one disclosed value after the proof was built. Its commitment no longer reproduces, so its path stops reaching the root — which is the whole point of sending a proof instead of the payload.

Salts are fresh on every run, so the root changes each time even for an identical wire. Without them, an observer could confirm a guessed account number by hashing it. No post-quantum signature is produced here: this page demonstrates selective disclosure, and signing needs a key it has no business holding.

Verify Receipt Illustrative UX — this panel demonstrates the receiving-party flow.

Illustrative demonstration. This prototype shows the Wire Proof compliance UX with sample data; the verdict below illustrates the flow and does not run a real cryptographic check. To actually verify an H33 receipt against real ML-DSA-65 + H33-74, in your browser with no server, use the offline verifier or the public verifier. Wire Proof produces the same portable H33-74 evidence those tools check.

VALID illustrative

In production this is where receipt integrity, all three signatures, and the policy hash are confirmed. This panel illustrates that result; run the real check in the offline verifier.

Verification Details (illustrative)

Dilithium signature: Valid
FALCON signature: Valid

INVALID

Receipt could not be verified. Signature mismatch or receipt not found in registry.

Active Policies

Sanctions Screening

All originator and beneficiary entities are screened against OFAC SDN, EU Consolidated, UN Security Council, and HMT sanctions lists. Screening is performed on protected data — names and identifiers are validated without being transmitted in plaintext.

Show policy hash

—

Beneficiary Verification

Beneficiary identity is validated against the receiving institution's records. For EU transfers, LEI or national identifier is required per Article 14 of Regulation (EU) 2023/1113. Verification result is proven without disclosing the identifier.

Show policy hash

—

Jurisdiction Controls

Originator and beneficiary jurisdictions are validated against the institution's permitted corridor list. Sanctioned jurisdictions (DPRK, Iran, Syria, Crimea) are blocked. High-risk jurisdictions trigger enhanced conditions.

—

Travel Rule Compliance

Validates that originator and beneficiary information is present as described in FATF Recommendation 16. For transfers over $3,000 / EUR 1,000, full originator details must be available. Wire Proof confirms completeness without transmitting all fields.

Risk Scoring

Composite risk score calculated from transaction amount, corridor risk, counterparty history, and pattern analysis. Score range 0.00 (lowest) to 1.00 (highest). Threshold: ≤0.30 auto-clear, 0.31-0.70 conditions, >0.70 blocked for review.

Wire Initiated

2026-04-24T14:32:14.102Z

▸ Originating bank submitted MT103 payload with 47 fields

Meridian Capital Partners LLC initiated a USD 2,450,000.00 wire to Nextera Industrial GmbH (Germany). Standard MT103 format with full field set. Payment reference: INV-2026-04881.

✓

Protected Validation Started

2026-04-24T14:32:14.108Z

▸ 47 fields encoded for protected validation

All 47 MT103 fields were encoded in protected form within the originator's environment. No plaintext data left the originator boundary. Protected encoding completed in 0.4ms.

✓

Compliance Signals Evaluated

2026-04-24T14:32:17.312Z

▸ 5/5 signals passed: sanctions, beneficiary, jurisdiction, travel rule, risk

Sanctions screening: Clear (OFAC, EU, UN, HMT). Beneficiary verification: Confirmed against NXTRDEFFXXX records. Jurisdiction: US-DE corridor permitted. Travel Rule: All required originator/beneficiary fields present. Risk score: 0.12 (low).

✓

Disclosure Policy Applied

2026-04-24T14:32:17.318Z

▸ 5 fields disclosed, 42 fields proven without disclosure

Active policy (sha3-256:e4b2c9...) applied. Disclosed: originator name, originator BIC, beneficiary name, amount, payment reference. Withheld with proof: account numbers, addresses, risk assessments, source of funds, and 37 additional MT103 fields.

✓

Receipt Signed

2026-04-24T14:32:17.841Z

▸ Triple-signed with Dilithium, FALCON, and SLH-DSA

A wire commitment is produced: a Merkle root over 47 salted SHA3-256 field commitments. The five policy-required fields travel with inclusion paths; the other 42 stay behind. No signature is produced on this page — it demonstrates selective disclosure, and signing would need a key it has no business holding. The elapsed time shown is the run you performed.

▸ Wire queued for SWIFT settlement with compressed payload

Wire submitted to SWIFT network with 5 disclosed fields plus cryptographic receipt. Receiving bank (NXTRDEFFXXX) can verify compliance proof independently. Expected settlement: T+0 (same day).
