Storefront-scoped JWT API keys

Programmatic B2B access

OpenAPI specification

Automated client generation

Demo application

Versioned releases

Semver-tagged releases of the SDK and server components. Pin a version, upgrade on your timeline.

02/ SDK

Drop-in checkout.

Our consumer-facing SDK is a React component. TypeScript-first, MIT-licensed, and designed to work across all five networks out of the box.

Open-source payment SDK

Handles wallet connection, network switching, transaction signing, and confirmation tracking. Style it with your own tokens, self-host it, or use our hosted widget.

quick-integration.tsx
import { Web3SettleCheckout } from '@web3settle/sdk'

<Web3SettleCheckout
  merchantId="your-merchant-id"
  amount={29.99}
  currency="USDT"
  networks={['ethereum', 'polygon', 'base']}
  onSuccess={(tx) => console.log('Payment confirmed:', tx.hash)}
  onError={(err) => console.error('Payment failed:', err)}
/>
03/ REST API

Full programmatic control.

Deploy contracts, read deposits, configure webhooks, pull analytics. JWT-authenticated, scoped per storefront, IP-allowlisted if you want.

Your infrastructure, your rules.

Deploy the payment SDK on your own infrastructure. Strict data residency, bespoke compliance, full control.

Docker-first

Pull the image, set your merchant ID, run. That’s the whole setup. Alongside this site, pair it with our backend OpenAPI spec for automated client generation.

docker run -p 3000:3000 -e MERCHANT_ID=your-id web3settle/payment-sdk
