Custom Chains

Custom Chains

Create a custom chain

You can use the Chain type to help you create a custom chain. Then, pass that to getDefaultConfig or Wagmi's createConfig.

For example, here's how you can create an Avalanche chain for avax.network.

import { RainbowKitProvider, getDefaultConfig, Chain, } from '@rainbow-me/rainbowkit';
import { WagmiProvider } from 'wagmi';
import { QueryClientProvider, QueryClient, } from "@tanstack/react-query";
const avalanche = {
id: 43_114,
name: 'Avalanche',
iconUrl: 'https://s2.coinmarketcap.com/static/img/coins/64x64/5805.png',
iconBackground: '#fff',
nativeCurrency: { name: 'Avalanche', symbol: 'AVAX', decimals: 18 },
rpcUrls: {
default: { http: ['https://api.avax.network/ext/bc/C/rpc'] },
},
blockExplorers: {
default: { name: 'SnowTrace', url: 'https://snowtrace.io' },
},
contracts: {
multicall3: {
address: '0xca11bde05977b3631167028862be2a173976ca11',
blockCreated: 11_907_934,
},
},
} as const satisfies Chain;
const config = getDefaultConfig({
appName: 'My RainbowKit App',
projectId: 'YOUR_PROJECT_ID',
chains: [avalanche],
});
const queryClient = new QueryClient();
const App = () => {
return (
<WagmiProvider config={config}>
<QueryClientProvider client={queryClient}>
<RainbowKitProvider>
{/* Your App */}
</RainbowKitProvider>
</QueryClientProvider>
</WagmiProvider>
);
};
