Welcome to the NID Integration Portal. This hub provides all the technical resources needed to build decentralized identity features into your third-party applications.

NID (Native Identity) is a multi-chain identity layer on Base that allows users to protect sensitive data while letting authorized providers "reveal" it on-demand.

Authentication (SIWE)

NID uses Lit Protocol and SIWE (Sign-In with Ethereum) to authorize data access. As a Provider, your app must sign a session signature to request decryption keys.

const authSig = await signer.signMessage({
    statement: "I am signing in as an Authorized Provider for NID.",
    nonce: await litNodeClient.getLatestBlockhash()
});

Installation

To start using NID in your project, include the NID Resolver SDK. You can copy the raw SDK file from our GitHub or use the snippet below.

import { nidResolver } from './sdk/nidResolver.js';

const uid = await nidResolver.reveal('user1.nid', 'App1:UID', signer, 'GAME');

Live Demo Playground

Test the "Magic Reveal" flow here. If your wallet is an authorized provider for the target NID role, the data will be revealed below.

Security Best Practices

Always perform the reveal() signature on your **Server-Side** (Node.js/Go) to ensure your App's Private Key is never exposed to the browser. Scoped roles ensure you only have access to data the user has specifically permitted.
