Why NEUS

People and products repeat the same identity, ownership, risk, and permission work in every new system. NEUS saves supported results as Portable Proofs so a connected product can evaluate them under its own rules.

Use one proof model for profiles, product gates, paid access, and AI agents. A proof is reusable only when the receiving product accepts its source and the proof still meets its policy.

NEUS does not replace authentication, specialist verification providers, application policy, payment processing, agent runtimes, or complete audit logs. The integration must call the check and enforce the result on the protected path.

Need	What you get with NEUS
Reuse a completed check	A proof with source, status, scope, and expiry
Keep proofs in one profile	Private-by-default proof management and selective sharing
Add verification to an app	Hosted sign-in, API, SDK, and React widgets
Sell protected access	Published checks, price, hosted checkout, and a server confirmation
Set limits on an AI agent	Owner, optional spend account, allowed and denied actions, expiry, and revocation

Choose a path

Add the hosted MCP remote, then click Connect.

Then ask:

Reuse what I already have. Before a sensitive action, check my current proofs.

NEUS answers Passed, Action needed, or Blocked. Full steps: MCP setup.

Capability snapshot

The live verifier catalog is documented at docs.neus.network/verification/verifiers. JSON Schemas live in docs/verifiers/schemas/; the machine index is spec/VERIFIERS.json.

Capability	Verifiers
Ownership and identity	ownership-basic, ownership-social, ownership-dns-txt, ownership-org-oauth, ownership-pseudonym
Human and wallet trust	proof-of-human, wallet-risk, wallet-link
Assets and contracts	token-holding, nft-ownership, contract-ownership

Open standard

NEUS is a reference implementation of CAIP-380 (Portable Proof) (PR), a ChainAgnostic standard at Draft status. Wallet-signed request envelopes use a deterministic SHAKE-256 hash (qHash), CAIP-2 chain context, and CAIP-10 / did:pkh identities. The hash, DID binding, and signature can be checked without NEUS. Verifier outcomes remain part of the NEUS portable proof. The envelope works with any CAIP-2 namespace and that chain’s native signing scheme. See Standards & interoperability, the offline examples, the CAIP-380 docs, and the Technical Whitepaper.
