Migration Guide

Migrating RainbowKit

2.x.x Breaking changes

The wagmi and viem peer dependencies have reached 2.x.x with breaking changes.

Follow the steps below to migrate.

1. Upgrade RainbowKit, wagmi, and viem to their latest versions

npm i @rainbow-me/rainbowkit@2 wagmi@2 viem@2.x

2. Install @tanstack/react-query peer dependency

With Wagmi v2, TanStack Query is now a required peer dependency.

Install it with the following command:

npm i @tanstack/react-query

3. Upgrade your RainbowKit and Wagmi configurations

  import '@rainbow-me/rainbowkit/styles.css'


+ import { QueryClient, QueryClientProvider } from '@tanstack/react-query'
- import { createPublicClient, http } from 'viem'
- import { WagmiConfig } from 'wagmi'
+ import { WagmiProvider, http } from 'wagmi'
- import { configureChains, createConfig } from 'wagmi'
  import { mainnet } from 'wagmi/chains'
  import { RainbowKitProvider } from '@rainbow-me/rainbowkit'
- import { getDefaultWallets, connectorsForWallets } from '@rainbow-me/rainbowkit'
+ import { getDefaultConfig } from '@rainbow-me/rainbowkit'


  /* getDefaultWallets is now optional */
- const { wallets } = getDefaultWallets({
-   appName: 'RainbowKit demo',
-   projectId: 'YOUR_PROJECT_ID',
-   chains,
- })


  /* connectorsForWallets is now optional */
- const connectors = connectorsForWallets([...wallets])


- const { chains, publicClient } = configureChains( 
-   [mainnet, sepolia], 
-   [publicProvider(), publicProvider()],
- )


- const config = createConfig({
-   autoConnect: true,
-   publicClient,
- })


  /* New API that includes Wagmi's createConfig and replaces getDefaultWallets and connectorsForWallets */
+ const config = getDefaultConfig({
+   appName: 'RainbowKit demo',
+   projectId: 'YOUR_PROJECT_ID',
+   chains: [mainnet],
+   transports: {
+     [mainnet.id]: http(),
+   },
+ })


+ const queryClient = new QueryClient()


  const App = () => {
    return (
-     <WagmiConfig config={config}>
+     <WagmiProvider config={config}>
+       <QueryClientProvider client={queryClient}>
-         <RainbowKitProvider chains={chains}>
+         <RainbowKitProvider>
            {/* Your App */}
          </RainbowKitProvider>
+       </QueryClientProvider>
-     </WagmiConfig>
+     </WagmiProvider>
    )
  }

4. Check for breaking changes in wagmi and viem

If you use wagmi hooks and viem actions in your dApp, you will need to follow the migration guides for v2:

RainbowKit Changes

1. Improved behavior for EIP-6963 wallets

Wallets that support the new EIP-6963 connection standard (including Rainbow, MetaMask, and more) will now automatically appear in an Installed section during the Connect Wallet experience. This ensures that users can always find their favorite wallets and connect to dApps without conflicts or fallback buttons.

Developers continue to have full control over the Custom Wallet List to emphasize preferred wallets for end users. It is encouraged that you continue to include the injectedWallet and walletConnectWallet in your list to supports all platforms.

2. Wagmi configuration with getDefaultConfig

This new API simplifies the configuration experience and replaces the need to use Wagmi's createConfig directly. Chain configuration is simplified, including inferred public providers for transports.

The default wallet list will be automatically included, deprecating the need to use getDefaultWallets and connectorsForWallets.

You can create a Custom Wallet List by passing imported or Custom Wallet connectors to wallets. Instantiating wallet connectors and passing projectId and chains is no longer required.

const config = getDefaultConfig({

  appName: 'RainbowKit demo',

  projectId: 'YOUR_PROJECT_ID',

  chains: [mainnet],

  wallets: [rainbowWallet], /* optional custom wallet list */

  /* Wagmi createConfig options including `transports` are also accepted */

})

3. RainbowKitProvider

You no longer need to pass chains to <RainbowKitProvider>.

- <RainbowKitProvider chains={chains}>
+ <RainbowKitProvider>

4. Custom Chains

The Chain type has changed in accordance with Wagmi v2, and continues to support RainbowKit's iconUrl and iconBackground metadata.

+ import { Chain } from '@rainbow-me/rainbowkit'


  const avalanche = {
    id: 43_114,
    name: 'Avalanche',
    iconUrl: 'https://s2.coinmarketcap.com/static/img/coins/64x64/5805.png',
    iconBackground: '#fff',
    nativeCurrency: { name: 'Avalanche', symbol: 'AVAX', decimals: 18 },
    rpcUrls: {
      default: { http: ['https://api.avax.network/ext/bc/C/rpc'] },
    },
    blockExplorers: {
      default: { name: 'SnowTrace', url: 'https://snowtrace.io' },
    },
    contracts: {
      multicall3: {
        address: '0xca11bde05977b3631167028862be2a173976ca11',
        blockCreated: 11_907_934,
      },
    },
  } as const satisfies Chain

Example with getDefaultConfig:

const config = getDefaultConfig({

+ chains: [
+   avalanche, /* custom chain */
+   {
+     ...mainnet,
+     iconBackground: '#000',
+     iconUrl: 'https://example.com/icons/ethereum.png',
+   }, /* metadata overides */
+ ],
});

Example with createConfig:

+ import { Chain } from '@rainbow-me/rainbowkit'
+ const chains: readonly [Chain, ...Chain[]] = [
+   {
+     ...mainnet,
+     iconBackground: '#000',
+     iconUrl: 'https://example.com/icons/ethereum.png',
+   },
+ ];
  const config = createConfig({
    chains,
    transports: {
      [mainnet.id]: http(),
    },
  })

5. Custom Wallets

RainbowKit wallet connectors have undergone substantial changes to support Wagmi v2. Reference the updated docs and an example connector to upgrade any Custom Wallet Connectors in your dApp.

Wallet connectors also now support the EIP-6963 standard with the rdns prop. Ensure that this is populated to prevent duplicate references to EIP-6963 supporting wallets in your wallet list.

1.x.x Breaking changes

Updated to wagmi v1

The wagmi peer dependency has been updated to 1.x.x.

Follow the steps below to migrate.

1. Upgrade RainbowKit and wagmi to their latest version

npm i @rainbow-me/rainbowkit@^1 wagmi@^1

2. Install viem peer dependency

wagmi v1 requires the viem peer dependency. Install it with the following command:

npm i viem

Note: wagmi no longer uses the ethers package internally. But if you rely on the Authentication API, siwe will still require ethers as a peer dependency.

3. Ensure bundler and polyfill compatibility

In previous versions of wagmi that relied on ethers, the fs, net, and tls modules required by WalletConnect were automatically polyfilled. This is no longer the case with RainbowKit v1 + wagmi v1, which are built on viem.

Reference our Next.js Webpack Config and Create React App polyfills samples for configuration guidance for your project.

Additional framework guides for Vite and Remix are available here.

4. Check for breaking changes in wagmi

If you use wagmi hooks in your application, you will need to follow wagmi's migration guide to v1.

You can see their migration guide here.

0.12.x Breaking changes

The wagmi peer dependency has been updated to 0.12.x.

RainbowKit has adopted the WalletConnectLegacyConnector connector in wagmi for continued WalletConnect v1 support. Support for WalletConnect v2 and WalletConnectConnector will soon be available as a patch release, without breaking changes.

Wallets will be transitioned automatically in future releases.

Every dApp must now provide a WalletConnect Cloud projectId to enable WalletConnect v2. This must be completed before WalletConnect v1 bridge servers are shutdown on June 28, 2023. RainbowKit will quietly prefer v1 for all wallets if projectId is unspecified.

Follow the steps below to migrate.

1. Upgrade RainbowKit and wagmi to their latest version

npm i @rainbow-me/rainbowkit@^0.12.0 wagmi@^0.12.0

2. Supply a WalletConnect Cloud projectId

Every dApp that relies on WalletConnect now needs to obtain a projectId from WalletConnect Cloud. This is absolutely free and only takes a few minutes.

Provide the projectId to getDefaultWallets and individual RainbowKit wallet connectors like the following:

const projectId = 'YOUR_PROJECT_ID';



const { wallets } = getDefaultWallets({

  appName: 'My RainbowKit App',

  projectId,

  chains,

});



const connectors = connectorsForWallets([

  ...wallets,

  {

    groupName: 'Other',

    wallets: [

      argentWallet({ projectId, chains }),

      trustWallet({ projectId, chains }),

      ledgerWallet({ projectId, chains }),

    ],

  },

]);

0.11.x Breaking changes

You can see their migration guide here.

0.7.x Breaking changes

If you're creating a custom wallet list, you must now import each wallet individually in order to reduce bundle size. Note that since wallets are no longer namespaced via the wallet object, all wallets now have a Wallet suffix.

-import { connectorsForWallets, wallet } from '@rainbow-me/rainbowkit';
+import { connectorsForWallets } from '@rainbow-me/rainbowkit';
+import {
+  injectedWallet,
+  rainbowWallet,
+  metaMaskWallet,
+  coinbaseWallet,
+  walletConnectWallet,
+} from '@rainbow-me/rainbowkit/wallets';


const wallets = [

-  wallet.injected({ chains }),
-  wallet.rainbow({ chains }),
-  wallet.metaMask({ chains }),
-  wallet.coinbase({ chains, appName: 'My App' }),
-  wallet.walletConnect({ chains }),
+  injectedWallet({ chains }),
+  rainbowWallet({ chains }),
+  metaMaskWallet({ chains }),
+  coinbaseWallet({ chains, appName: 'My App' }),
+  walletConnectWallet({ chains }),
];

Also note that the Steakwallet backwards compatibility layer has been removed. Omni should be used instead.

-import { wallet } from '@rainbow-me/rainbowkit';
+import { omniWallet } from '@rainbow-me/rainbowkit/wallets';


const wallets = [

-  wallet.steak({ chains }),
+  omniWallet({ chains }),
];

0.4.x Breaking changes

RainbowKit has updated the wagmi peer dependency to 0.5.x.

Follow the steps below to migrate.

1. Upgrade dependencies

Upgrade RainbowKit and wagmi to their latest version

npm i @rainbow-me/rainbowkit@^0.4.0 wagmi@^0.5.0

2. Check for breaking changes in wagmi

You can see their migration guide here.

0.3.x Breaking changes

Removed the chainId parameter from createConnector on the Wallet type.

Note that all built-in wallets are using the new API. Most consumers will be unaffected. This change only affects consumers that have created/consumed custom wallets.

If you previously derived RPC URLs from the chainId on createConnector, you can now remove that logic as wagmi now handles RPC URLs internally when used with configureChains.

import { connectorsForWallets, wallet, Chain, Wallet } from '@rainbow-me/rainbowkit';

import { chain, configureChains } from 'wagmi';

import { alchemyProvider } from 'wagmi/providers/alchemy';

import { publicProvider } from 'wagmi/providers/public';

import { WalletConnectConnector } from 'wagmi/connectors/walletConnect';



export interface MyWalletOptions {

  chains: Chain[];
}



-const chains = [chain.mainnet]
+const { chains } = configureChains(
+  [chain.mainnet],
+  [
+    alchemyProvider({ alchemyId: process.env.ALCHEMY_ID }),
+    publicProvider(),
+  ]
+);


export const rainbow = ({ chains }: MyWalletOptions): Wallet => ({

  ...
- createConnector: ({ chainId }) => {
+ createConnector: () => {
-   const rpc = chains.reduce(
-     (rpcUrlMap, chain) => ({
-       ...rpcUrlMap,
-       [chainId]: chain.rpcUrls.default,
-     }),
-     {}
-   );
    const connector = new WalletConnectConnector({
      chains,
      options: {
        qrcode: false,
-       rpc,
      },
    });
  }
  ...
}



const connectors = connectorsForWallets([

  {
    groupName: 'Recommended',
    wallets: [
      rainbow({ chains }),
    ],
  },
]);

0.2.x Breaking changes

RainbowKit has updated the wagmi peer dependency to ^0.4.

Follow the steps below to migrate.

1. Upgrade dependencies

Upgrade RainbowKit and wagmi to their latest version

npm i @rainbow-me/rainbowkit@^0.2.0 wagmi@^0.4.2

2. Replace configureChains import

Import configureChains from wagmi instead of RainbowKit:

- import { configureChains } from '@rainbow-me/rainbowkit';
+ import { configureChains } from 'wagmi';

3. Migrate providers

RainbowKit no longer exports an apiProvider API. Replace it with your desired provider from wagmi.

- import { apiProvider } from '@rainbow-me/rainbowkit';

Alchemy

Import alchemyProvider from wagmi/providers/alchemy.

+ import { alchemyProvider } from 'wagmi/providers/alchemy';


const { chains, provider } = configureChains(

  [chain.mainnet, chain.polygon, chain.optimism, chain.arbitrum],
- [apiProvider.alchemy(process.env.ALCHEMY_ID)]
+ [alchemyProvider({ alchemyId: process.env.ALCHEMY_ID })]
);

Infura

Import infuraProvider from wagmi/providers/infura.

+import { infuraProvider } from 'wagmi/providers/infura';


const { chains, provider } = configureChains(

  [chain.mainnet, chain.polygon, chain.optimism, chain.arbitrum],
- [apiProvider.infura(process.env.INFURA_ID)]
+ [infuraProvider({ infuraId: process.env.INFURA_ID })]
);

JSON RPC

Import jsonRpcProvider from wagmi/providers/jsonRpc.

+ import { jsonRpcProvider } from 'wagmi/providers/jsonRpc';


const { chains, provider } = configureChains(

  [chain.mainnet, chain.polygon],
  [
-   apiProvider.jsonRpc(chain => ({
-     rpcUrl: `https://${chain.id}.example.com`,
-   })),
+   jsonRpcProvider({
+     rpc: chain => ({
+       http: `https://${chain.id}.example.com`,
+     }),
+   }),
  ]
);

Public provider

Import publicProvider from wagmi/providers/public.

+ import { publicProvider } from 'wagmi/providers/public';


const { chains, provider } = configureChains(

  [chain.mainnet, chain.polygon],
- [apiProvider.fallback()]
+ [publicProvider()]
);

4. Rename wagmi's provider

Rename WagmiProvider to WagmiConfig.

import {

- WagmiProvider
+ WagmiConfig
} from 'wagmi'



const App = () => {

  return (
-   <WagmiProvider client={wagmiClient}>...</WagmiProvider>
+   <WagmiConfig client={wagmiClient}>...</WagmiConfig>
  );
};

And you're done! 🌈
