# Configure external connector chains

> Configure which chain types (EVM, Solana) external wallet connectors support in your app

Privy supports connecting wallets on both EVM networks and Solana to your application. To configure your app for the wallet types you need, follow the steps below.

## Configuring EVM/Solana external connectors

<Tabs>
  <Tab title="EVM and Solana">
    <Tip>
      If you are connecting to Solana wallets, you must also initialize Solana connectors using Privy's `toSolanaWalletConnectors` method and pass them to the `config.externalWallets.solana.connectors` field.
    </Tip>

    In your `PrivyProvider`, set the `config.appearance.walletChainType` to `'ethereum-and-solana'`.

    ```tsx theme={"system"}
    import {PrivyProvider} from '@privy-io/react-auth';
    import {toSolanaWalletConnectors} from "@privy-io/react-auth/solana";

    <PrivyProvider
      config={{
        appearance: {walletChainType: 'ethereum-and-solana'},
        externalWallets: {solana: {connectors: toSolanaWalletConnectors()}}
      }}
    >
      {children}
    </PrivyProvider>
    ```

    `toSolanaWalletConnectors` accepts an optional `shouldAutoConnect` parameter (defaults to `true`) that silently reconnects previously-authorized Solana wallets on page load. Set it to `false` if connecting a wallet on page load triggers an unwanted connection prompt.
  </Tab>

  <Tab title="EVM">
    In your `PrivyProvider`, set the `config.appearance.walletChainType` to `'ethereum-only'`.

    ```tsx theme={"system"}
    import {PrivyProvider} from '@privy-io/react-auth';

    <PrivyProvider
      config={{
        appearance: {walletChainType: 'ethereum-only'}
      }}
    >
      {children}
    </PrivyProvider>
    ```
  </Tab>

  <Tab title="Solana">
    <Tip>
      If you are connecting to Solana wallets, you must also initialize Solana connectors using Privy's `toSolanaWalletConnectors` method and pass them to the `config.externalWallets.solana.connectors` field.
    </Tip>

    In your `PrivyProvider`, set the `config.appearance.walletChainType` to `'solana-only'`.

    ```tsx theme={"system"}
    import {PrivyProvider} from '@privy-io/react-auth';
    import {toSolanaWalletConnectors} from "@privy-io/react-auth/solana";

    <PrivyProvider
      config={{
        appearance: {walletChainType: 'solana-only'},
        externalWallets: {
          solana: {connectors: toSolanaWalletConnectors()}
        }
      }}
    >
      {children}
    </PrivyProvider>
    ```

    `toSolanaWalletConnectors` accepts an optional `shouldAutoConnect` parameter (defaults to `true`) that silently reconnects previously-authorized Solana wallets on page load. Set it to `false` if connecting a wallet on page load triggers an unwanted connection prompt.
