Manan Tank

The BridgeWidget Script makes it easy to embed cross-chain swaps and fiat onramp UI into your app. Just add a script tag to your HTML and get a fully customizable widget — no build setup required.

BridgeWidget UI

Key Features

  • Cross-chain token swaps across 80+ blockchains
  • Fiat onramp support to buy tokens with credit/debit cards
  • Customizable UI — use prebuilt themes or override with your brand colors
  • Prefill token selections for a smoother user experience
  • Display fiat values in multiple currencies
  • Event callbacks to track user actions (success, error, cancel, disconnect)

<script src="https://unpkg.com/thirdweb/dist/scripts/bridge-widget.js"></script>
<!-- Add a container element where you want to render the UI -->
<div id="bridge-widget-container"></div>
<!-- Initialize the widget at the end of <body> -->
<script>
  const container = document.querySelector('#bridge-widget-container');
