Zero-Knowledge Identity

Verify EverythingStore Nothing

The double-blind identity layer. Verify users via their wallet, get a signed receipt, and keep zero PII on your servers.

Compliance receipts you can actually show auditors

Double-blind: platforms see outcomes, not identity

One credential across web2, web3, and internal tools

Compliance-grade receiptsFit straight into your logs, audits, and partner reviews.

Standards we ship

  • W3C VC 2.0
  • OID4VP 1.0
  • ISO 18013-5 mdoc
  • W3C Digital Credentials API

Posture

  • Double-blind architecture
  • SOC 2 Type I in progress
Complexity goes in, a simple answer comes out.
Zero-Knowledge means you never see the raw data.

The "prove it" era

Regulators want proof. Users want privacy.
Solve for both without the friction.

The Challenge

Can you proveyou checked age & location?

Regulators are demanding evidence, not just checkboxes. The old way of "trust me" is over.

Privacy First

GDPR and new laws demand data minimisation. Don't store what you don't need.

Protection by Design
Zero PII Storage

The "ID Warehouse" Trap

Storing sensitive docs creates a massive breach surface. Hackers don't steal "Pass/Fail" answers; they steal passports.

Breach RiskLegal Exposure

Nexion gives you the proof without the liability.

Why teams build with Nexion

The infrastructure for the next generation of privacy-preserving apps.

Compliance without the cache

Replace "store every document forever" with Pass/Fail outcomes and compact policy receipts you can reuse across audits, investigations, and partner reviews.

Auditors get cryptographic proof of policy enforcement without ever seeing identity data. Receipts contain claims and signatures, not personal records.

  • Compact receipts
  • Audit-ready
  • Reusable across reviews

Zero PII on your servers, across every check.

Compliance Story

Wallet-native credentials

Put KYC-grade proofs into a wallet users control. The same Pass/Fail check can gate exchanges, DeFi frontends, games, and fintech features, while identity stays off your core systems.

Use Cases

Developer first architecture

Standards-based verifier with SDKs, test sandboxes, and JSON receipts that plug into your existing auth, risk, and observability stack, all without rewriting your whole login system.

Developer Docs

Two sides, one protocol

For Platforms

Integrate compliance without the toxic liability of storing PII.

  • Launch age- and region-gated features without building your own KYC pipeline
  • Give risk, legal, and security teams signed records of every policy check
  • Use one wallet-based verifier across web2, web3, and internal tools

For Users

Prove who you are without revealing everything about yourself.

  • Set up identity once in their own wallet, then prove what's needed (and nothing else) on every check
  • Re-use the same credential across exchanges, apps, and games
  • See where credentials were used and revoke a device if it's lost

Three steps to trust

Step 01

Verify Once

The user completes a one-time eKYC flow in the Nexion wallet with government ID and selfie. The wallet holds a verifiable credential that encodes statements like "over 18", "resident of country X", or "eligible under your onboarding policy".

Step 02

Instant Check

Your app asks the wallet to prove a rule, such as age, region, or eligibility. The wallet evaluates it on-device and returns a Pass/Fail decision plus a signed policy receipt for your logs.

Step 03

Zero-Click Reuse

On return visits, a passkey proves it's the same person on the same device. Your latest policies are re-evaluated; your systems keep outcomes and receipts, not raw identity data.
