Trust Must Not Restart From Zero. We Built The Portable Trust Layer.

Every new agent and interaction starts from zero: unknown, no memory, no limits, no proof. A user proves they are human on one platform, then starts from scratch on the next. A developer wires custom access control for every new project. An AI agent moves value with no verifiable identity, leaving an audit trail no one can inspect, reuse, or enforce. The same layer covers sign-ups, marketplaces, payouts, and partner handoffs. Agents are the most visible symptom, but the problem is universal: trust restarts at every border. NEUS fixes this at the infrastructure layer. Today, NEUS is generally available. NEUS makes trust portable across the internet, so people, apps, and AI agents can prove what is real before access, payout, or execution. ## From Verification to Trust Infrastructure Most products check you once, then forget the result. The next app asks the same questions again. The cost is duplicated engineering, fragmented security, privacy leakage, and user churn. NEUS turns a trust decision into a reusable receipt. Prove once. Check anywhere. Every downstream app, gate, agent, or auditor reads what was already verified instead of rebuilding the check. Every trust decision reduces to three questions. NEUS answers each one with a portable receipt. - **Verification:** Is this real? Prove identity, ownership, humanity, an organization, a domain, or a wallet. The result becomes a trust receipt any app or agent can check. - **Authority:** What may it do? Grant scoped authority to people, agents, or wallets. Enforce limits before action. Revoke when policy changes. - **Ownership:** Whose is it, and what happened? Record every trusted action and every denial. Produce a portable, auditable record that survives the surface that created it. ## What You Can Use Today ### NEUS Verify and Hosted Verify A request hits the verifier catalog and returns a cryptographic outcome as a durable receipt. End users verify without writing code at [neus.network/verify](https://neus.network/verify). Receipts generate instantly and are reusable across the ecosystem. ### Trust Receipts Every verification produces a receipt anchored by a unique qHash. Off-chain by default, with optional on-chain anchoring where immutable settlement is required. Passes get receipts. Denials get receipts. Third parties run eligibility checks against existing receipts; they do not rerun the full proof. ### SDK and React Widgets One command installs the SDK: ```bash npx -y -p @neus/sdk neus setup ``` Two React components cover the UI layer: - **VerifyGate:** gate routes or content by verifier eligibility - **ProofBadge:** surface verified status as a readable, shareable badge ### API A REST API for server-side reads, eligibility checks, verifier catalog discovery, and direct verification. Every response is backed by the same receipt layer as the hosted flow and SDK. ### Agent Infrastructure AI agents that move value or access sensitive data need provenance, not just a system prompt. - **Agent Identity:** portable, self-signed IDs - **Agent Delegation:** scoped authority compatible with ERC-8004 - **Stable URLs:** persistent endpoints that resolve to live trust graphs - **Action Receipts:** cryptographic records of every delegated action ### MCP Integration NEUS exposes a live Model Context Protocol server at [[https://mcp.neus.network/mcp](https://mcp.neus.network/mcp)](https://mcp.neus.network/mcp](https://mcp.neus.network/mcp)). Compatible with Claude Code, Codex, Cursor, VS Code, Cline, and OpenAI agents. Before a sensitive tool runs, the assistant surfaces a verification summary to the user. ### Vault The user-managed profile layer for receipts, agents, secrets, and access controls. You own your trust graph and choose what is public, private, or delegated. ## For Developers, AI Engineers, and End Users For developers, NEUS replaces bespoke auth middleware with reusable trust primitives. Drop VerifyGate into a React app, call the API from your backend, and stop maintaining custom verification pipelines. For AI engineers, NEUS gives agents verifiable identity and scoped authority before action. Register an agent, delegate permissions, and bind every action to a cryptographic record that platforms can audit. For end users, NEUS means verifying once and reusing the receipt across any application that accepts the protocol. Receipts stay private by default; you opt in to on-chain anchoring or broader sharing explicitly. ## Ecosystem and Network Effects Portable trust compounds. As more applications accept NEUS receipts, the cost of verification collapses for everyone. A user who proves ownership once can reuse that proof at a marketplace, a DAO gate, or an AI agent runtime. A developer who integrates VerifyGate inherits the verifier catalog without custom integrations. The network layer is open source. NEUS is trust infrastructure any app, agent, or ecosystem can adopt. ## Live Now The verifier catalog includes 14 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 - **Content and Safety:** ai-content-moderation - **Agent Trust:** agent-identity, agent-delegation Supported chains: EVM and Solana. Authentication: OAuth-first by default, with profile access keys for server and CI environments. ## Start Building Today - **Developers:** Read the docs at [[docs.neus.network](http://docs.neus.network)]([https://docs.neus.network](https://docs.neus.network)) and run `npx -y -p @neus/sdk neus setup`. - **AI engineers:** Point your MCP client to [[https://mcp.neus.network/mcp](https://mcp.neus.network/mcp)](https://mcp.neus.network/mcp](https://mcp.neus.network/mcp)). - **End users:** Claim your profile and generate your first receipt at [[neus.network](http://neus.network)]([https://neus.network](https://neus.network)). - **Platforms:** Integrate the SDK, accept NEUS receipts, and stop rebuilding verification from scratch. Trust that travels.
