BridgeWidget

A combined widget for swapping or buying tokens with cross-chain support.

This component renders two tabs – "Swap" and "Buy" – and orchestrates the appropriate flow by composing SwapWidget and BuyWidget under the hood.

The Swap tab enables token-to-token swaps (including cross-chain).
The Buy tab enables purchasing a specific token; by default, it uses card onramp in this widget.

Example

Basic usage


<BridgeWidget
  client={client}
  currency="USD"
  theme="dark"
  showThirdwebBranding
  buy={{
    // Buy 0.1 native tokens on Base
    amount: "0.1",
    chainId: 8453,
  }}
/>;

Prefill swap tokens and configure buy


<BridgeWidget
  client={client}
  swap={{
    prefill: {
      buyToken: {
        // Base USDC
        chainId: 8453,
        tokenAddress: "0x833589fcd6edb6e08f4c7c32d4f71b54bda02913",
      },
      sellToken: {
        // Polygon native token (MATIC)
        chainId: 137,
      },
    },
  }}
  buy={{
    amount: "100",
    chainId: 8453,
    tokenAddress: "0x833589fcd6edb6e08f4c7c32d4f71b54bda02913",
    buttonLabel: "Buy USDC",
  }}
/>;
