Solana Updates

​
Update Peer Dependencies

If your app uses Privy’s Solana wallets, the required peer dependencies have changed in v3.0: Remove these peer dependencies:
  • @solana/web3.js
  • @solana/spl-token
Install these new peer dependencies:
  • @solana/kit
  • @solana-program/memo
  • @solana-program/system
  • @solana-program/token

​
Solana RPC configuration

  • For Privy embedded wallet flows only (UI signTransaction and signAndSendTransaction), set RPCs in config.solana.rpcs. This replaces solanaClusters.
import {createSolanaRpc, createSolanaRpcSubscriptions} from '@solana/kit'; 

<PrivyProvider
  appId="your-privy-app-id"
  config={{
    ...theRestOfYourConfig,
    solanaClusters: [{name: 'mainnet-beta', rpcUrl: 'https://api.mainnet-beta.solana.com'}] 
    solana: {  
      rpcs: { 
        'solana:mainnet': { 
          rpc: createSolanaRpc('https://api.mainnet-beta.solana.com'), 
          rpcSubscriptions: createSolanaRpcSubscriptions('wss://api.mainnet-beta.solana.com') 
        }, 
      }
    }
  }}
>
  {/* your app's content */}
</PrivyProvider>;

​
Replace useSolanaWallets

  • Replace useSolanaWallets with useWallets, useCreateWallet, and useExportWallet from the Solana entrypoint. The new useWallets hook returns ConnectedStandardSolanaWallet[].
import {useSolanaWallets} from '@privy-io/react-auth/solana'; 
import {useWallets, useCreateWallet, useExportWallet} from '@privy-io/react-auth/solana'; 

const {ready, wallets, createWallet, exportWallet} = useSolanaWallets(); 
const {ready, wallets} = useWallets(); 
const {createWallet} = useCreateWallet(); 
const {exportWallet} = useExportWallet();
Key differences between ConnectedSolanaWallet and ConnectedStandardSolanaWallet:
  • Each wallet represents a single connected account
  • Methods are available directly on the wallet instance:
    • wallet.signMessage({message})
    • wallet.signTransaction({transaction, chain})
    • wallet.signAndSendTransaction({transaction, chain})
    • wallet.signAndSendAllTransaction({transaction, chain}[])
    • wallet.disconnect()
  • The Solana standard wallet is available at wallet.standardWallet (for icon/name/etc.)
  • Removed wallet.loginOrLink() method - Use useLoginWithSiws and useLinkWithSiws instead:
import {useLoginWithSiws, useLinkWithSiws} from '@privy-io/react-auth'; 

const {generateSiwsMessage, loginWithSiws} = useLoginWithSiws(); 
const {generateSiwsMessage, linkWithSiws} = useLinkWithSiws(); 

// Login flow
await wallets[0].loginOrLink(); 
const message = await generateSiwsMessage({address: wallets[0].address}); 
const encodedMessage = new TextEncoder().encode(message); 
const results = await wallets[0].signMessage({message: encodedMessage}); 
await loginWithSiws({message: encodedMessage, signature: results.signature}); 

// Link flow (similar pattern with linkWithSiws)
const results = await wallets[0].signMessage({message: encodedMessage}); 
await linkWithSiws({message: encodedMessage, signature: results.signature});

​
Rename useSendTransaction

  • Update useSendTransaction from @privy-io/react-auth/solana to useSignAndSendTransaction from @privy-io/react-auth/solana
import {useSendTransaction} from '@privy-io/react-auth/solana'; 
import {useSignAndSendTransaction} from '@privy-io/react-auth/solana'; 

...

const {sendTransaction} = useSendTransaction(); 
const {signAndSendTransaction} = useSignAndSendTransaction();

​
Usage Examples

  • All Solana RPCs now expect buffer inputs.

​
New solana wallet usage

import {useWallets, type ConnectedStandardSolanaWallet} from '@privy-io/react-auth/solana';
import {TextEncoder} from '@solana/kit';

export function SolanaWallets() {
  const {ready, wallets} = useWallets();
  if (!ready) return <p>Loading...</p>;

  return (
    <div>
      {wallets.map((wallet: ConnectedStandardSolanaWallet) => (
        <div key={wallet.address}>
          <img src={wallet.standardWallet.icon} width={16} height={16} />
          <span>{wallet.standardWallet.name}</span>
          <code>{wallet.address}</code>
          <button
            onClick={async () => {
              const message = new TextEncoder().encode('Hello, world!');
              const {signature} = await wallet.signMessage({message});
              console.log('signature', signature);
            }}
          >
            Sign message
          </button>
        </div>
      ))}
    </div>
  );
}

​
Sign and send via hooks (with optional UI configuration)

import {
  useWallets,
  useSignMessage,
  useSignTransaction,
  useSignAndSendTransaction
} from '@privy-io/react-auth/solana';

export function Actions() {
  const {wallets} = useWallets();
  const {signMessage} = useSignMessage();
  const {signTransaction} = useSignTransaction();
  const {signAndSendTransaction} = useSignAndSendTransaction();

  const wallet = wallets[0];
  if (!wallet) return null;

  return (
    <div>
      <button
        onClick={async () => {
          const message = new TextEncoder().encode('Hello from Privy');
          const {signature} = await signMessage({
            wallet,
            message,
            options: {uiOptions: {showWalletUIs: true}}
          });
          console.log(signature);
        }}
      >
        Sign message (hook)
      </button>

      <button
        onClick={async () => {
          // Create an encoded transaction using @solana/kit or @web3.js
          const transaction = tx; // type Uint8Array
          const {signedTransaction} = await signTransaction({
            wallet,
            transaction,
            chain: 'solana:devnet'
          });
          console.log(signedTransaction);
        }}
      >
        Sign transaction (hook)
      </button>

      <button
        onClick={async () => {
          // Create an encoded transaction using @solana/kit or @web3.js
          const transaction = tx; // type Uint8Array
          const {signature} = await signAndSendTransaction({
            wallet,
            transaction,
            chain: 'solana:devnet'
          });
          console.log(signature);
        }}
      >
        Sign & send (hook)
      </button>
    </div>
  );
}
