Custom chains

Create a custom chain

You can use the Chain type to help you create a custom chain. Then, pass that to the configureChains function.

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

import {
  apiProvider,
  configureChains,
  getDefaultWallets,
} from '@rainbow-me/rainbowkit';
import { chain, createClient } from 'wagmi';

const avalancheChain: Chain = {
  id: 43_114,
  name: 'Avalanche',
  nativeCurrency: {
    decimals: 18,
    name: 'Avalanche',
    symbol: 'AVAX',
  },
  rpcUrls: {
    default: 'https://api.avax.network/ext/bc/C/rpc',
  },
  blockExplorers: {
    default: { name: 'SnowTrace', url: 'https://snowtrace.io' },
    snowtrace: { name: 'SnowTrace', url: 'https://snowtrace.io' },
  },
  testnet: false,
};

const { provider, chains } = configureChains(
  [avalancheChain],
  [apiProvider.jsonRpc(chain => ({ rpcUrl: chain.rpcUrls.default }))]
);

const { connectors } = getDefaultWallets({
  appName: 'My RainbowKit App',
  chains,
});

const wagmiClient = createClient({
  autoConnect: true,
  connectors,
  provider,
});

const App = () => {
  return (
    <WagmiProvider client={wagmiClient}>
      <RainbowKitProvider chains={chains}>
        <YourApp />
      </RainbowKitProvider>
    </WagmiProvider>
  );
};
