One proof receipt. Reusable across every app, API, and agent.

​
What NEUS Does

Every product needs to verify users for login, access control, and trust. But each verification is typically:
  • Fragmented — Built separately for each feature
  • Non-portable — Can’t reuse proofs across apps
  • Expensive — Custom infrastructure per use case
NEUS replaces fragmented verification with one reusable proof receipt. Verify once. Use that proof everywhere — login, gating, policy, and agent workflows.

​
How It Works

┌─────────────┐     ┌─────────────┐     ┌─────────────────┐
│   Verify    │────▶│  Proof ID   │────▶│  Reuse Anywhere │
│   (once)    │     │  (receipt)  │     │  (apps, agents) │
└─────────────┘     └─────────────┘     └─────────────────┘
  1. Verify — User completes verification (wallet, social, human check)
  2. Receive — Get back a portable proof receipt ID
  3. Reuse — Same proof works across all your products
