Web3Modal v5 to Reown AppKit - Web | Wagmi

This guide will help you upgrade from Web3Modal v5 using Wagmi to the latest Reown AppKit. Find here all the upgrades guides:

​
Installation

To upgrade from Web3Modal v5 to Reown AppKit start by removing Web3Modal v5 dependencies @web3modal/ethereum and @web3modal/react. Now you can install AppKit library and update Wagmi and Viem.
npm install @reown/appkit @reown/appkit-adapter-wagmi @tanstack/react-query

​
Implementation

You can start the AppKit configuration by using either the default or advanced mode.Default mode will implement WalletConnect, Browser Wallets (injected) and Coinbase options in addition to Wagmi’s public clients and WalletConnect’s provider.
Make sure to set your configuration outside React components to avoid unwanted rerenders.
Start by importing createAppKit from @reown/appkit and the necessary chains from @reown/appkit/networks
// Remove the following imports
- import { createWeb3Modal } from '@web3modal/wagmi/react'
- import { defaultWagmiConfig } from '@web3modal/wagmi/react/config'
- import { arbitrum, mainnet } from 'viem/chains'

// Add the following imports
+ import { createAppKit } from '@reown/appkit/react'
+ import { arbitrum, mainnet } from '@reown/appkit/networks'
+ import { WagmiAdapter } from '@reown/appkit-adapter-wagmi'

import { QueryClient, QueryClientProvider } from '@tanstack/react-query'
Then create wagmiAdapter using WagmiAdapter function as shown below
const projectId = 'YOUR_PROJECT_ID'
const queryClient = new QueryClient()

const metadata = { //optional
    name: 'AppKit',
    description: 'AppKit Example',
    url: 'https://example.com',
    icons: ['https://avatars.githubusercontent.com/u/179229932']
}

// Remove the existing Wagmi Config
+ const wagmiConfig = defaultWagmiConfig({ chains, projectId, metadata })

// Create the Wagmi adapter
+ const wagmiAdapter = new WagmiAdapter({
  networks: [mainnet, arbitrum],
  projectId
})
Finally, pass wagmiAdapter and other parameters to createAppKit
// Remove the following line
- createWeb3Modal({ wagmiConfig, projectId, chains })

// Add the following line
+ createAppKit({
 adapters: [wagmiAdapter],
 networks: [mainnet, arbitrum],
 metadata: metadata,
 projectId,
 features: {
   analytics: true,
 }
})

export default function App() {
  return (
    <>
    // Remove the following line
-   <WagmiProvider config={wagmiConfig}>

    // Add the following line
+   <WagmiProvider config={wagmiAdapter.wagmiConfig}>
      <QueryClientProvider client={queryClient}>
        <HomePage />
      </QueryClientProvider>
    </WagmiProvider>
    </>
  )
}

​
Trigger the modal

// Remove the following import
- import { useWeb3Modal } from '@web3modal/wagmi/react'

// Add the following import
+ import { useAppKit } from '@reown/appkit/react'

function HomePage() {
  const { open } = useAppKit()

  return <button onClick={open}>Connect</button>
}
You can also use a web component to trigger the modal. You can simply use <appkit-button />.Learn more about Reown AppKit here.

​
Properties

As you may have noticed, some of the properties of Web3Modal have changed as a consequence of the migration to Reown AppKit.

​
adapters

The adapters property is a new property that is an array of adapters that can be initialized.

​
networks

The chains property is now networks in Reown AppKit. You should import them from @reown/appkit/networks package instead of importing these networks from viem or other packages.

​
defaultNetwork

The defaultChain property is now defaultNetwork in Reown AppKit. This is a network object that specifies the default network for your Web3 app.

​
Utility Functions

The following methods are still available with the same nomenclature as before: This returns the connected address.
It returns the active namespace’s address.Example: You’ve initialized both the Wagmi and Solana adapters and connected to a dApp with an EVM-only wallet (e.g., Rainbow). In this case, the Solana adapter is still not connected. When your active network is one of the EVM chains, the address will return your wallet address. However, if you manually switch to the Solana network, the address will return undefined (unless you connect to a Solana wallet).
This returns the error values. Returns the active network’s chainId
In versions prior to v5, which were single-chain, getChainId() returned a single type rather than multiple types:
  • @web3modal/wagmi (along with ethers and ethers5) returned number | undefined.
  • @web3modal/solana returned string | undefined.
Now, in Reown AppKit, since both chains can be connected simultaneously, the type definition is number | string | undefined.
This switches the active network to the different network being passed.
Unlike in v5, modal.switchNetwork takes the chain object as parameter rather than the chain id.
  • (v5) - switchNetwork(137) -> switches the chain to Polygon as we are passing Polygon’s chain id.
  • (Reown AppKit v1) - switchNetwork(polygon) -> polygon is imported from @reown/appkit/networks.
// Remove the following code line
- modal.switchNetwork(137);

// Add the following code lines
+ import { polygon } from "@reown/appkit/networks";
+ modal.switchNetwork(polygon);
This returns if the selected network adapter is connected or not.
It returns the active namespace’s connection status as a boolean.Example: You’ve initialized both the Wagmi and Solana adapters and connected to the dApp with an EVM-only wallet (e.g., Rainbow). In this case, the Solana adapter is still not connected. When you manually switch to the Solana network from the network selection list, you will see a disconnected state because the Solana adapter cannot use Rainbow’s connection. As a result, it will prompt you to connect with a Solana wallet.
This returns the active connection provider. This returns the active connection provider type. This is a listener that detects changes to the AppKit state, such as address, chainId, isConnected, provider, and providerType.
  • address - It returns the connected wallet address. The value returned is the same as modal.getAddress()
  • chainId - It returns the active network’s chainId . The value returned is the same as modal.getChainId()
  • isConnected - It returns if the selected network adapter is connected. The value returned is the same as modal.getIsConnected()
  • provider - It returns the active connection provider. The value returned is the same as modal.getWalletProvider()
  • providerType - It returns the active connection provider type. The value returned is the same as modal.getWalletProviderType()
The following methods and listeners are exactly the same and do not have any specific details related to the multiple chains feature.
  • modal.getState - it returns the modal state
    • open - it returns boolean that indicates if the modal is open or not
    • selectedNetworkId - it returns active network’s id
  • modal.subscribeState
  • modal.setThemeMode
  • modal.getThemeMode
  • modal.setThemeVariables
  • modal.getThemeVariables
  • modal.subscribeTheme
  • modal.getEvent
  • modal.subscribeEvents
