Quick start
Authenticate users and access wallets in a few lines of code.
import { KIDAuth } from '@kid-oauth/sdk';
const auth = new KIDAuth({
clientId: 'YOUR_CLIENT_ID',
redirectUri: 'https://yourapp.com/callback'
});
// Generate login URL with PKCE
const loginUrl = auth.createLoginUrl({
scope: 'profile.basic wallet.read'
});
// Exchange code for tokens
const tokens = await auth.exchangeCode(code);
// Get user info with wallet
const user = await auth.getUserInfo(tokens.access_token);
console.log(user.wallet_address);Everything you need

Read https://dash.kid.koompi.org/llms.txt and implement KID OAuth in my Next.js app: 1. Create login button with PKCE flow 2. API route for token exchange (/api/auth/callback) 3. Token refresh endpoint (/api/auth/refresh) 4. Get user profile with wallet address 5. Store tokens in httpOnly cookies 6. Support wallet.read and wallet.transfer scopes
Three steps to production
Create a project
Register your app in the dashboard. Get your client_id and client_secret.
client_id: 'abc123.kid.koompi.org'Install the SDK
Add @kid-oauth/sdk to your project and configure the login flow.
npm install @kid-oauth/sdkShip it
Users authenticate and automatically receive a blockchain wallet.
