⚠️ Vulnerable to Financial Message Fraud?
A European private bank lost €14.7M when hackers spoofed payment instructions via compromised telex lines. Our KTT Guarantee Solution provides:
- Biometric Authentication — voice/fingerprint verified test keys
- Chain-of-Custody Tracking — DLT (quantum-resistant ledger)
- Legal Non-Repudiation — ICC-admissible evidence packages
"NNRV's KTT system intercepted a $22M attempted heist by detecting manipulated test keys in 37 seconds. Their AI validation is now our first line of defense."
— CISO, Private Bank, Luxembourg

Frequently Asked Questions (15)
1) What is the core benefit of KTT over legacy telex?
Pre-transaction, real-time authentication and non-repudiation with biometric keys and DLT evidence, instead of manual, post-fact checks.
2) Which SWIFT messages are covered?
MT199/299 advisory flows and MT799 pre-advice; custom flows considered case-by-case.
3) Do we need new hardware?
We support HSMs (e.g., Thales nShield). Where not available, we offer managed HSM enclaves.
4) How are keys exchanged?
Initial bilateral, in-person key ceremony with multi-factor identity checks; subsequent rotations are automated.
5) What data is stored on DLT?
Hashes and metadata only—never full message content—preserving confidentiality while enabling integrity proofs.
6) Can KTT integrate with our SWIFT interface?
Yes—via API/connector pattern with your SWIFT gateway or service bureau.
7) How fast is verification?
Typically under 2 minutes end-to-end; sub-90-second paths are common.
8) What legal frameworks back non-repudiation?
ICC documentary standards, local e-signature/records laws, and our evidence pack procedures.
9) What training is required?
A 60–90 minute session for ops/treasury/IT, plus a key-ceremony runbook.
10) Is this “quantum-safe”?
We apply lattice-based primitives for key exchange layers and maintain crypto-agility for future PQC standards.
11) How are false positives handled?
Alerts include confidence scoring and a dual-approval workflow to avoid disruption.
12) What if a counterparty refuses KTT?
We can operate in “bridge mode” alongside their legacy checks while maintaining our audit trail.
13) What are typical fees?
From 0.08% of transaction (min $500), plus optional setup/retainer where bespoke integrations are needed.
14) Do you support biometric privacy?
Yes—templates are stored as salted hashes; we never store raw biometrics.
15) Can we trial before full rollout?
Yes—sandbox and limited corridor pilots are available following KYC/AML checks.
