Multichain

AppKit is now multichain. The architecture is designed to support both EVM and non-EVM blockchains. This will allow developers and projects to choose and configure multiple blockchain networks within their instance of AppKit, extending beyond just Ethereum-based (EVM) networks.

Currently, AppKit supports one non-EVM, Solana. Soon, AppKit will support Bitcoin, Polkadot, and Cosmos, allowing projects to tap into users from these different blockchain ecosystems. This will enable developers and projects to reach a broader audience and interact with multiple blockchain networks, all through a single wallet provider.

Installation​

npm install @reown/appkit-adapter-wagmi @reown/appkit-adapter-solana @solana/wallet-adapter-wallets

Integration​

The AppKit instance allows you to support multiple chains by importing the respective chains, creating the respective network adapters and passing these within the createAppKit() function.

Depending on the network adapter of your preference (Wagmi, Ethers, Ethers5), the integration may vary. Let's look at what the integration will look like.

import { createAppKit } from '@reown/appkit'
import { SolanaAdapter } from '@reown/appkit-adapter-solana'
import { WagmiAdapter } from '@reown/appkit-adapter-wagmi'

import { solana, solanaTestnet, solanaDevnet } from '@reown/appkit/networks'
import { mainnet, arbitrum, sepolia } from '@reown/appkit/networks'

import { SolflareWalletAdapter, PhantomWalletAdapter } from '@solana/wallet-adapter-wallets'

export const networks = [solana, solanaTestnet, solanaDevnet]

// 0. Get projectId from https://cloud.reown.com
const projectId = 'YOUR_PROJECT_ID'

// 1. Create the Wagmi adapter
export const wagmiAdapter = new WagmiAdapter({
  ssr: true,
  projectId, 
  networks
})

// 2. Create Solana adapter
const solanaWeb3JsAdapter = new SolanaAdapter({
  wallets: [new PhantomWalletAdapter(), new SolflareWalletAdapter()]
})

// 3. Set up the metadata - Optional
const metadata = {
  name: 'AppKit',
  description: 'AppKit Example',
  url: 'https://web3modal.com', // origin must match your domain & subdomain
  icons: ['https://avatars.githubusercontent.com/u/179229932']
}

// 4. Create the AppKit instance
const modal = createAppKit({
  adapters: [wagmiAdapter, solanaWeb3JsAdapter],
  networks: [mainnet, arbitrum, sepolia, solana, solanaTestnet, solanaDevnet],
  metadata: metadata,
  projectId,
  features: {
    analytics: true,
  }
})
