Revolutionary Features

Enterprise-grade identity infrastructure that works across every blockchain

Universal Onboarding

Any blockchain address instantly becomes a universal did:authrix identity. No complex setup, no new wallets — just instant universal access.

Instant Any Chain Zero Setup

Cross-Chain Sync

Real-time identity synchronization across all supported blockchains. Update once, verified everywhere.

Real-time 50+ Chains Auto-sync

Privacy-First

Selective disclosure with BBS+ signatures and zero-knowledge proofs. Share only what's needed, keep everything else private.

BBS+ ZK-Proofs GDPR Ready

Lightning Fast

Sub-50ms DID resolution with multi-layer caching. 100x–1000x cheaper than native blockchain operations.

<50ms 100x Cheaper L1/L2/L3 Cache

Enterprise Ready

HSM integration, threat detection, and comprehensive compliance. SOC 2, GDPR, HIPAA ready with automated governance.

HSM SOC 2 Compliance

No Smart Contract Risk

VDK bridge architecture eliminates smart contract vulnerabilities. Monitor-only approach with Accumulate L0 as single source of truth.

Only degree and graduation year revealed — identity verified via BBS+ proof

Selective Disclosure

Share only what's needed. Prove you're over 21 without revealing your exact age or any other personal data.

Zero-Knowledge Proofs

Prove statements are true without revealing the underlying data. Cryptographic guarantees with no information leakage.

BBS+ Signatures

Cryptographic signatures that enable unlinkable selective disclosure. Multi-message signing with efficient proof generation.
