ENTERPRISE-READY ARCHITECTURE
Core Components of Our DID for KYC/AML Solution
A modular, secure-by-design identity stack that replaces legacy KYC/AML processes with verifiable credentials and selective disclosure, reducing compliance costs and onboarding friction.
01
W3C Verifiable Credential Engine
Issue and verify tamper-proof credentials using W3C standards. We implement selective disclosure and zero-knowledge proofs, allowing users to prove compliance (e.g., age, residency) without exposing raw PII.

Decentralized Identity for KYC/AML
Frequently Asked Questions
Answers to common technical and commercial questions about implementing self-sovereign identity for compliant payments.
We implement a verifiable credential model using the W3C DID and VC standards. Users create a self-sovereign wallet (DID) and receive attested credentials (e.g., proof of identity, accredited investor status) from trusted issuers like financial institutions. These credentials are stored locally and presented via zero-knowledge proofs for specific transaction checks, eliminating the need to share raw PII. Our system integrates with your payment flow to verify credentials against AML lists and jurisdictional rules in real-time, ensuring compliance without centralized data silos.
