What is NEUS at a protocol level?

NEUS is an open verification protocol for portable proofs. Proofs are created via wallet signatures (EIP‑191), identified by a proof ID (qHash), and verified by modular verifiers without requiring a new transaction for every verification.

How does cross-chain storage work?

A proof has one qHash. You can optionally propagate storage to additional chains for redundancy using target chain options. On-chain verifiers still reference the verifier’s asset chain inside verifier data (e.g., NFT/token chainId).

What is public vs private proof visibility?

NEUS is privacy-first. Public proofs are intentionally shareable; private proofs restrict access and require fresh wallet signatures to read details. Apps can still verify requirements without exposing sensitive content by default.

Why does qHash matter?

qHash is the portable handle for a proof. It is what apps and users share, embed, and verify across environments, so proofs stay composable instead of siloed per app.

How do developers integrate without user accounts?

Use the NEUS SDK or API. Wallet signatures serve as authorization, so you can gate access and verify users without managing passwords or storing user auth state.

What verifiers exist today, and can I add my own?

Verifiers are modular. Common verifiers include ownership, NFT/token gating, DNS ownership, social OAuth, wallet risk, contract ownership, wallet linking, and more. Custom verifiers can be built and contributed as the protocol evolves.

Protocol

The Network

One verification, endless reuse.

NEUS standardizes verification into a reusable receipt that apps and agents can check without forcing people to re-verify from scratch.

Start verifying

Build with SDK

// Create a portable proof receipt
const proof = await client.verify({
  verifier: 'ownership-basic',
  content: 'Prove ownership once',
  options: {
    privacyLevel: 'public',
    targetChains: [1, 11155111]
  }
});

console.log('Proof created:', proof.qHash);

Proof without the stack.
