Default Chains and Tokens

Squid Widget v2.0: Default Chains and Tokens Configuration Guide

This guide explains how to configure default chains and tokens for the Squid Widget v2.0. Note that there have been significant changes from previous versions.

Finding Chain IDs and Token Addresses

Before configuring, you'll need to know the correct chain IDs and token addresses:

• Chain IDs:

  • Use Squid's API playground

  • Or access the chains endpoint directly

• Token Addresses:

  • Use the tokens endpoint

  • Or filter by chain in the API playground (input the chain ID in the /tokens reference)

Configuring Initial Assets (Chains and Tokens)

In Squid v2.0, initialFromChainId and initialToChainId have been replaced by the initialAssets object:

<SquidWidget
  config={{
    initialAssets: {
      from: {
        address: "0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee", // Token address
        chainId: "1", // Ethereum
      },
      to: {
        address: "0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee", // Token address
        chainId: "42161", // Arbitrum
      },
    },
    // ... other configuration options
  }}
/>

Configuring Default Tokens Per Chain

The defaultTokens property has been renamed to defaultTokensPerChain:

<SquidWidget
  config={{
    defaultTokensPerChain: [
      {
        address: "0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee", // ETH on Ethereum
        chainId: "1",
      },
      {
        address: "0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee", // ETH on Arbitrum
        chainId: "42161",
      },
    ],
    // ... other configuration options
  }}
/>

Removed Features

Please note that the following features have been removed in Squid v2.0:

• favTokens: Favorite tokens are no longer supported.

• Several other properties including companyName, titles, enableExpress, mainLogoUrl, and others. Refer to the migration guide for a full list.

Full Example

Here's a complete example combining these configurations:

import { SquidWidget } from '@0xsquid/widget';

function App() {
  return (
    <SquidWidget
      config={{
        integratorId: "<your-integrator-id>",
        apiUrl: "https://apiplus.squidrouter.com",
        initialAssets: {
          from: {
            address: "0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee",
            chainId: "1",
          },
          to: {
            address: "0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee",
            chainId: "42161",
          },
        },
        defaultTokensPerChain: [
          {
            address: "0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee",
            chainId: "1",
          },
          {
            address: "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE",
            chainId: "42161",
          },
        ],
        // ... other configuration options
      }}
    />
  );
}

export default App;
