This document outlines the steps to migrate from the old @web3modal packages to the new multichain @reown/appkit packages in your React Native project.

​
Overview of Changes

The new AppKit architecture introduces a core library with pluggable chain adapters, providing better support for multiple blockchains (EVM, Solana, Bitcoin) in a single integration. Key Changes:
  • Core Library: Use @reown/appkit-react-native as the main package
  • Chain Adapters: Install specific adapters for each blockchain you want to support
  • Unified API: All hooks and components are imported from the core package
  • Multichain Support: Native support for EVM, Solana, and Bitcoin chains
  • Wagmi
  • Ethers
Step 1. Replace the dependencies using package manager commandsFor Yarn users:Remove the old Web3Modal packages:
yarn remove @web3modal/wagmi-react-native @web3modal/email-wagmi-react-native @web3modal/coinbase-wagmi-react-native @web3modal/siwe-react-native
Add the new Reown AppKit packages:
# Core AppKit library and dependencies
yarn add @reown/appkit-react-native @react-native-async-storage/async-storage react-native-get-random-values react-native-svg @react-native-community/netinfo @walletconnect/react-native-compat

# Wagmi adapter and its dependencies
yarn add @reown/appkit-wagmi-react-native wagmi viem@2.x @tanstack/react-query

# Optional: Additional adapters for other chains
yarn add @reown/appkit-solana-react-native @reown/appkit-bitcoin-react-native
Step 2. Update your AppKit configurationCreate a new AppKitConfig.ts file with the multichain setup:
// src/AppKitConfig.ts
import "@walletconnect/react-native-compat"; // MUST BE THE FIRST IMPORT

import { createAppKit } from "@reown/appkit-react-native";
import { WagmiAdapter } from "@reown/appkit-wagmi-react-native";
import { mainnet, sepolia } from "wagmi/chains";

const projectId = "YOUR_PROJECT_ID"; // Obtain from https://dashboard.reown.com/

const metadata = {
  name: "My Awesome dApp",
  description: "My dApp description",
  url: "https://myapp.com",
  icons: ["https://myapp.com/icon.png"],
  redirect: {
    native: "YOUR_APP_SCHEME://",
    universal: "YOUR_APP_UNIVERSAL_LINK.com",
  },
};

// Initialize Wagmi adapter
const wagmiAdapter = new WagmiAdapter({
  projectId,
  networks: [mainnet, sepolia], // Add all chains you want to support
});

export const appKit = createAppKit({
  projectId,
  metadata,
  networks: [mainnet, sepolia], // Must match the networks in wagmiAdapter
  adapters: [wagmiAdapter],
  // ... other AppKit options
});

// Export the wagmi config for provider setup
export const wagmiConfig = wagmiAdapter.wagmiConfig;
Step 3. Update your App.tsx with providers
// App.tsx
import React from 'react';
import { SafeAreaProvider } from 'react-native-safe-area-context';
import { AppKitProvider } from '@reown/appkit-react-native';
import { WagmiProvider } from 'wagmi';
import { QueryClient, QueryClientProvider } from '@tanstack/react-query';
import { appKit, wagmiConfig } from './AppKitConfig';
import YourAppRootComponent from './YourAppRootComponent';

const queryClient = new QueryClient();

function App() {
  return (
    <SafeAreaProvider>
      <AppKitProvider instance={appKit}>
        <WagmiProvider config={wagmiConfig}>
          <QueryClientProvider client={queryClient}>
            <YourAppRootComponent />
          </QueryClientProvider>
        </WagmiProvider>
      </AppKitProvider>
    </SafeAreaProvider>
  );
}

export default App;
Step 4. Update your component with AppKit UI
// YourAppRootComponent.tsx
import React from 'react';
import { AppKit } from '@reown/appkit-react-native';
// ... other imports

function YourAppRootComponent() {
  return (
    <>
      {/* Your application's content */}
      <AppKit /> {/* This renders the modal and other AppKit UI */}
    </>
  );
}

export default YourAppRootComponent;
Step 5. Update your Hooks usageUpdate your hook imports as follows:
// Remove the following code lines
import {
  useWeb3Modal,
  useWeb3ModalState,
  useWeb3ModalEvents,
  useWalletInfo,
} from "@web3modal/wagmi-react-native";

// Add the following code lines
import {
  useAppKit,
  useAppKitState,
  useAppKitEventSubscription,
  useWalletInfo,
} from "@reown/appkit-react-native";
Step 6. Update your Components usageUpdate your component imports as follows:
// Remove the following code lines
import {
  W3mAccountButton,
  W3mButton,
  W3mConnectButton,
  W3mNetworkButton,
  Web3Modal,
} from "@web3modal/wagmi-react-native";

// Add the following code lines
import {
  AccountButton,
  AppKitButton,
  ConnectButton,
  NetworkButton,
  AppKit,
} from "@reown/appkit-react-native";
Step 7. Update your config for Universal WalletsRemove email wallet specific imports as follows:
// Remove the following code lines
import { emailConnector } from "@web3modal/email-wagmi-react-native";
Step 8. Update your import to support Coinbase WalletUpdate coinbase connector import as follows:
// Remove the following code lines
import { coinbaseConnector } from "@web3modal/coinbase-wagmi-react-native";

// Add the following code lines
import { MMKV } from 'react-native-mmkv';
import { CoinbaseConnector } from '@reown/appkit-coinbase-react-native';

export const appKit = createAppKit({
  // ...
  extraConnectors: [
    new CoinbaseConnector({ storage: new MMKV() })
  ],
  // ...
});

Key Migration Notes

​
New Hook Structure

  • useWeb3Modal → useAppKit (includes open, close, disconnect, switchNetwork)
  • useWeb3ModalState → useAppKitState
  • useWeb3ModalEvents → useAppKitEventSubscription
  • useWeb3ModalAccount → useAccount
  • useWeb3ModalProvider → useProvider
  • useDisconnect → useAppKit

​
New Component Structure

  • Web3Modal → AppKit
  • W3mButton → AppKitButton
  • W3mConnectButton → ConnectButton
  • W3mAccountButton → AccountButton
  • W3mNetworkButton → NetworkButton

​
Multichain Support

The new AppKit supports multiple blockchains natively. You can add support for Solana and Bitcoin by installing their respective adapters: 
# For Solana support
yarn add @reown/appkit-solana-react-native

# For Bitcoin support
yarn add @reown/appkit-bitcoin-react-native
Then add them to your AppKitConfig.ts: 
import { SolanaAdapter } from "@reown/appkit-solana-react-native";
import { BitcoinAdapter } from "@reown/appkit-bitcoin-react-native";
import { solana, bitcoin } from "@reown/appkit-react-native";

const solanaAdapter = new SolanaAdapter();
const bitcoinAdapter = new BitcoinAdapter();

export const appKit = createAppKit({
  // ...
  networks: [mainnet, polygon, solana, bitcoin],
  adapters: [ethersAdapter, solanaAdapter, bitcoinAdapter],
  // ...
});

Final notes

  • Ensure that you have updated all relevant configurations and imports in your project to reflect the changes from Web3Modal to the new multichain AppKit.
  • Test your application thoroughly to ensure that the migration has been successful and that all functionality is working as expected.
  • Check our AppKit examples for React Native to compare with your implementation in case you are having issues
  • For detailed information about the new architecture, see the Migration to Multichain guide
