Getting Started

ConnectKit is the simplest way to integrate a connect wallet experience into your React.js web application. It comes with sensible defaults out of the box so you can focus on building.

Install ConnectKit and its peer dependencies (wagmi and viem).

npm install connectkit wagmi viem

Start by importing wagmi and ConnectKit, then create a config using either wagmi's createConfig method or the pre-configured getDefaultConfig ConnectKit provides.

Below is a simple example app using getDefaultConfig() to help you get started:

import { WagmiConfig, createConfig } from "wagmi";
import { ConnectKitProvider, ConnectKitButton, getDefaultConfig } from "connectkit";

const config = createConfig(
  getDefaultConfig({
    // Required API Keys
    alchemyId: process.env.ALCHEMY_ID, // or infuraId
    walletConnectProjectId: process.env.WALLETCONNECT_PROJECT_ID,

    // Required
    appName: "Your App Name",

    // Optional
    appDescription: "Your App Description",
    appUrl: "https://family.co", // your app's url
    appIcon: "https://family.co/logo.png", // your app's icon, no bigger than 1024x1024px (max. 1MB)
  }),
);

const App = () => {
  return (
    <WagmiConfig config={config}>
      <ConnectKitProvider>
        /* Your App */
        <ConnectKitButton />
      </ConnectKitProvider>
    </WagmiConfig>
  );
};

And voilà, you've successfully set up ConnectKit.

In a lot of use cases, you will want to access the connected wallet from ConnectKit in order to be able to interact with it further. You can do so by using the different hooks, such as useAccount, from wagmi (a ConnectKit dependency).

In the previous example above we wrapped our app with a <ConnectKitProvider> top-level. Before utilizing any wagmi hook, make sure the components you build are mounted under this provider.

Below is a simple example component that utilizes the useAccount hook to access connection state and the connected wallet address:

import { useAccount } from "wagmi";

// Make sure that this component is wrapped with ConnectKitProvider
const MyComponent = () => {
  const { address, isConnecting, isDisconnected } = useAccount();
  if (isConnecting) return <div>Connecting...</div>;
  if (isDisconnected) return <div>Disconnected</div>;
  return <div>Connected Wallet: {address}</div>;
};

That's it—you now have a simple component that displays the connected wallet's address.

Some build tools require additional setup to work with ConnectKit.

ConnectKit uses WalletConnect's SDK to help with connecting wallets. WalletConnect 2.0 pulls in Node.js dependencies that Next.js does not support by default.

You can mitigate this by adding the following to your next.config.js file:

module.exports = {
  webpack: (config) => {
    config.resolve.fallback = { fs: false, net: false, tls: false };
    return config;
  },
};

Below is a list of React.js components we provide as part of the library:
