Solana wallet integration
This guide will walk you through the process of integrating Solana Wallets into your Para Modal and Para-enabled application, allowing you to onboard new users and connect with existing users who may already have external wallets like Phantom, Backpack and more.

​
Prerequisites

Before integrating wallet connections, ensure you have an existing Para project with the Para Modal set up. If you haven’t set up Para yet, follow one of our Framework Setup guides like this guide.

​
Setting up Solana Wallets

Setup is simple - just wrap your app in a provider and pass the appropriate props and configuration options to the provider. Once configured, the Para modal and wallet options will automatically appear in the modal when opened. Para provides seamless integration with popular Solana wallets including , , , and .

​
Import components

Import the wallet connectors and supporting components you need. Adjust the imports based on which wallets you want to support:
main.tsx
import { WalletAdapterNetwork } from "@solana/wallet-adapter-base";
import { clusterApiUrl } from "@solana/web3.js";
import {
  ParaProvider,
  ExternalWallet,
} from "@getpara/react-sdk";
import { QueryClient, QueryClientProvider } from "@tanstack/react-query";

​
Configure the Solana network

Set up your Solana network configuration. Choose the appropriate network for your deployment environment:
main.tsx
const solanaNetwork = WalletAdapterNetwork.Devnet;
const endpoint = clusterApiUrl(solanaNetwork);

​
Configure the providers

Configure the ParaProvider component by wrapping your application content in the QueryClientProvider and ParaProvider components. Pass in the required configuration props:
main.tsx
export const App = () => {
  return (
    <QueryClientProvider client={queryClient}>
      <ParaProvider
        // ... rest of your provider config
        externalWalletConfig: {
          wallets: [ExternalWallet.Backpack],
          appUrl: `${location.protocol}//${location.host}`,
          solanaConnextor: {
            config: {
              endpoint,
              chain: solanaNetwork
            },
          },
          walletConnect: {
            projectId: 'your_walletconnect_project_id',
          },
        }>
        {/* Your app content */}
      </ParaProvider>
    </QueryClientProvider>
  );
};

​
External Wallet Configuration

​
External Wallets with Linked Embedded Wallets

You can also provision linked embedded wallets for external wallets. In this case, the external wallet would be the Para auth method for the user’s embedded wallet (instead of an email or social login). Embedded wallets would be created according to your API key settings. To enable this, you can include the createLinkedEmbeddedForExternalWallets prop to indicate which external wallets this setting should be applied to.

​
Advanced Provider Pattern

Setting up a dedicated provider component that encapsulates all the necessary providers and modal state management is considered a best practice. This pattern makes it easier to manage the modal state globally and handle session management throughout your application.

​
Server-Side Rendering Considerations

When using Next.js or other SSR frameworks, proper client-side initialization is crucial since web3 functionality relies on browser APIs. There are two main approaches:
  1. Using the 'use client' directive in Next.js 13+:
    • Add the directive at the component level where browser APIs are needed. If using a custom provider, add the directive to the top of the provider file.
    • Ensures the Web3Provider component and its dependencies only run on the client side
  2. Using dynamic imports:
    • In Next.js, use the dynamic function to import the provider component with { ssr: false }.
    • Lazily loads the provider component
    • Automatically handles client-side only code
    • Provides fallback options during loading

​
Configuring the Para Modal

After setting up your providers you need to configure the ParaModal component to display the external wallets and authentication options to your users. You need to pass in the externalWallets and authLayout configuration options to the ParaModal component to control which of the wallets show in the modal that were specified in the provider configuration.

​
Set the modal props

paraModalConfig={{  
  authLayout: ["AUTH_FULL","EXTERNAL_FULL"]
  theme: {
    mode: "light",
    foregroundColor: "#000000",
    backgroundColor: "#FFFFFF",
    accentColor: "#007AFF"
  }
  logo: yourLogoUrl
  // ... other modal config
}}
Modal prop options for customizing the Para Modal are included below. For advanced customization options, refer to .

​
External Wallet Verification

External wallet verification adds a verification step during external connection to ensure the user owns the wallet. Enabling this feature establishes a valid Para session, which you can later use in your app to securely validate wallet ownership. To enable this, set the following option on your externalWalletConfig of your ParaProvider: 
externalWalletConfig={{
  includeWalletVerification: true,
  ...REST_OF_CONFIG
}}

​
Connection Only Wallets

Connection only external wallets bypass all Para functionality (account creation, user tracking, etc.) when connecting an external wallet. To enable this, set the following option on your externalWalletConfig of your ParaProvider: 
externalWalletConfig={{
  connectionOnly: true,
  ...REST_OF_CONFIG
}}
Since connection only wallets bypass Para, most Para functionality will be unavailable. This includes linked embedded wallets, external wallet verification, on & off ramping, etc.
