Configuration

WIP

React

Configure the Wormhole Connect React component by passing a WormholeConnectConfig object as the config attribute

import WormholeConnect, { WormholeConnectConfig } from '@wormhole-foundation/wormhole-connect';

const config: WormholeConnectConfig = {
  networks: ["ethereum", "polygon", "solana"],
  tokens: ["ETH", "WETH", "MATIC", "WMATIC"],
  rpcs: {
    ethereum: "https://rpc.ankr.com/eth",
    solana: "https://rpc.ankr.com/solana",
  }
}

// ...

<WormholeConnect config={config} />

HTML Tags

If using the hosted version, provide config and theme as JSON-serialized strings on the mount point:

<div
  id="wormhole-connect"
  data-config='{"tokens":["ETH","WETH","WBTC","USDCeth"]}'
  data-theme='{"background":{"default": "#81c784"}}'
/>

Examples

Below are some examples of different ways you can configure Connect.

See WormholeConnectConfig in src/config/index.ts for a full view of the supported config parameters.

Custom networks and RPC endpoints

Specify supported networks/tokens and custom RPC endpoints. Your users may encounter rate limits using public RPC endpoints if you do not provide your own

import WormholeConnect, {
  WormholeConnectConfig,
} from "@wormhole-foundation/wormhole-connect";

const config: WormholeConnectConfig = {
  env: "mainnet",
  networks: ["ethereum", "polygon", "solana"],
  tokens: ["ETH", "WETH", "MATIC", "WMATIC"],
  rpcs: {
    ethereum: "https://rpc.ankr.com/eth",
    solana: "https://rpc.ankr.com/solana",
  },
};

function App() {
  return <WormholeConnect config={config} />;
}

Fully customized theme

import WormholeConnect, {
  WormholeConnectTheme,
} from "@wormhole-foundation/wormhole-connect";
import red from "@mui/material/colors/red";
import lightblue from "@mui/material/colors/lightBlue";
import grey from "@mui/material/colors/grey";
import green from "@mui/material/colors/green";
import orange from "@mui/material/colors/orange";

const customTheme: WormholeConnectTheme = {
  mode: 'dark',
  primary: grey,
  secondary: grey,
  divider: 'rgba(255, 255, 255, 0.2)',
  background: {
    default: "#232323",
  },
  text: {
    primary: "#ffffff",
    secondary: grey[500],
  },
  error: red,
  info: lightblue,
  success: green,
  warning: orange,
  button: {
    primary: 'rgba(255, 255, 255, 0.2)',
    primaryText: "#ffffff",
    disabled: 'rgba(255, 255, 255, 0.1)',
    disabledText: 'rgba(255, 255, 255, 0.4)',
    action: orange[300],
    actionText: "#000000",
    hover: 'rgba(255, 255, 255, 0.7)',
  },
  options: {
    hover: "#474747",
    select: "#5b5b5b",
  },
  card: {
    background: "#333333",
    secondary: "#474747",
    elevation: "none",
  },
  popover: {
    background: "#1b2033",
    secondary: 'rgba(255, 255, 255, 0.5)',
    elevation: "none",
  },
  modal: {
    background: "#474747",
  },
  font: {
    primary: 'Impact',
    header: 'Impact',
  }
};

export default function App() {
  return <WormholeConnect theme={customTheme} />;
}

Environment

This shows how to run Connect on testnet.

const config: WormholeConnectConfig = {
  "env": "testnet"
}

Custom RPC Endpoint

This shows how to change which RPC provider Connect uses for a particular network.

const config: WormholeConnectConfig = {
  "rpcs": {
    "solana": "https://rpc.ankr.com/solana/ee827255553bb0fa9e0aaeab27e988707e60ea06ae36be0658b778072e94979e"
  }
}

Arbitrary Token

This shows how to add an arbitrary token to your deployment of Connect. Please note you will need to register your token with the Token Bridge to get the contract addresses necessary for it to work with Connect.

These example config limits Connect to the Solana and Ethereum networks, and a handful of tokens including BSKT which is not built in by default and provided under the tokensConfig key.

See src/config/types.ts for the type definition of TokensConfig.

const config: WormholeConnectConfig = {
  "networks": ["solana", "ethereum"],
  "tokens": ["ETH", "WETH", "MATIC", "WMATIC", "BSKT"],
  "tokensConfig": {
    "BSKT": {
      "key": "BSKT",
      "symbol": "BSKT",
      "nativeChain": "solana",
      "tokenId": {
        "chain": "solana",
        "address": "6gnCPhXtLnUD76HjQuSYPENLSZdG8RvDB1pTLM5aLSJA"
      },
      "coinGeckoId": "basket",
      "icon": "https://assets.coingecko.com/coins/images/34661/standard/BSKT_Logo.png?1705636891",
      "color": "#2894EE",
      "decimals": {
        "default": 5
      },
    }
  }
}
