Custom networks allow you to connect to blockchain networks that are not included by default in AppKit.

​
Adding Custom Networks

You can add custom networks to your AppKit configuration: 
import { createAppKit } from '@reown/appkit'
import { WagmiAdapter } from '@reown/appkit-adapter-wagmi'
import { mainnet } from '@reown/appkit/networks'

// Define your custom network
const customNetwork = {
  id: 1234,
  name: 'Custom Network',
  nativeCurrency: {
    decimals: 18,
    name: 'Custom Token',
    symbol: 'CTK',
  },
  rpcUrls: {
    default: {
      http: ['https://rpc.custom-network.com'],
    },
    public: {
      http: ['https://rpc.custom-network.com'],
    },
  },
  blockExplorers: {
    default: { name: 'Custom Explorer', url: 'https://explorer.custom-network.com' },
  },
}

const wagmiAdapter = new WagmiAdapter({
  networks: [mainnet, customNetwork],
  projectId
})

const appKit = createAppKit({
  adapters: [wagmiAdapter],
  networks: [mainnet, customNetwork],
  projectId
})
Make sure your custom network follows the proper network configuration format for your chosen adapter.
