Wormhole Connect is a customizable React widget that can perform cross-chain bridging with Wormhole.
Wormhole Connect is deployed live in several production apps. Here are a few:
If you're using React, you can import the <WormholeConnect /> component directly into your JSX:
npm i @wormhole-foundation/wormhole-connect
import WormholeConnect from '@wormhole-foundation/wormhole-connect';
function App() {
return (
<WormholeConnect />
);
}
If you're not using React, you can still embed Connect on your website by using the hosted version. Simply copy and paste the following code into your HTML body:
<!-- Mounting point. Include in <body> -->
<div id="wormhole-connect"></div>
<!-- Dependencies -->
<script type="module" src="https://www.unpkg.com/@wormhole-foundation/wormhole-connect@0.3.0/dist/main.js" defer></script>
<link rel="https://www.unpkg.com/@wormhole-foundation/wormhole-connect@0.3.0/dist/main.css" />
Note that the #wormhole-connect element has to be present before the scripts are loaded.
You can customize and integrate Connect via our no-code solution: https://connect-in-style.wormhole.com/
Wormhole Connect is highly customizable via two props: config and theme. Here is an example which
limits it to two chains and customizes the background color:
import WormholeConnect, {
WormholeConnectConfig, WormholeConnectPartialTheme
} from '@wormhole-foundation/wormhole-connect';
const config: WormholeConnectConfig = {
networks: ['ethereum', 'solana']
};
const theme: WormholeConnectPartialTheme = {
background: {
default: '#212b4a'
}
};
function App() {
return (
<WormholeConnect config={config} theme={theme} />
)
}
If using the hosted version, provide config and theme as JSON-serialized strings on the mount point:
<div id="wormhole-connect" data-config="{...}" data-theme="{...}"></div>
Below are some of the more commonly used config options. See the full Connect docs for more complete documentation and examples of the different config options.
env):Connect renders in mainnet mode by default, but you can switch it to testnet by setting env to testnet.
const config: WormholeConnectConfig = {
env: 'testnet'
}
rpcs):We strongly recommend that you configure your own custom RPC endpoints for each network your application needs. The default public RPCs may be throttled or rate limited.
const config: WormholeConnectConfig = {
rpcs: {
solana: 'https://mainnet.helius-rpc.com/?api-key=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx',
ethereum: 'https://rpc.ankr.com/eth/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
}
}
tokensConfig)You can add arbitrary tokens to the Connect tokens menu by providing a tokensConfig key.
const config: WormholeConnectConfig = {
tokensConfig: {
...
}
}
See the "Arbitrary Token" example in the config docs.
Please note you have to register a token with the token bridge before you can use it in Connect.
You can also customize Connect's color scheme by providing a WormholeConnectTheme as the theme prop.
By default, Connect renders using the dark theme.
import WormholeConnect, {
dark,
WormholeConnectTheme,
} from "@wormhole-foundation/wormhole-connect";
// alters the `dark` theme
const customized: WormholeConnectTheme = dark;
customized.success = '#212b4a';
customized.background.default = "navy";
customized.button.action = "#81c784";
customized.button.actionText = "#000000";
export default function App() {
return <WormholeConnect theme={customized} />;
}
You can change the theme prop to dynamically change Connect's colors, for example when your application
switches from light to dark mode.
See the definitions of WormholeConnectTheme and dark in theme.ts for type definitions.
networks):You can provide a whitelist of networks to limit which ones Connect offers.
const config: WormholeConnectConfig = {
networks: ['ethereum', 'solana']
}
By default, it offers its full built-in list for both mainnet and testnet:
mainnet | testnet |
|---|---|
| ethereum | goerli, sepolia |
| polygon | mumbai |
| bsc | bsc |
| avalanche | fuji |
| celo | avalanche |
| moonbeam | moonbasealpha |
| solana | solana |
| sui | sui |
| aptos | aptos |
| base | basegoerli, base_sepolia |
| osmosis | osmosis |
| evmos | evmos |
| kujira | kujira |
| injective | injective |
| klaytn | klaytn |
| arbitrum | arbitrumgoerli, arbitrum_sepolia |
| optimism | optimismgoerli, optimism_sepolia |
Osmosis support is in beta, reach out to a Wormhole contributor for early access.
