    return para.getDisplayAddress(wallet.id, {
      truncate: true,
      addressType: wallet.type
    });
  };

  const checkSessionStatus = async () => {
    if (!para) return;
    
    const isActive = await para.isSessionActive();
    console.log("Session active:", isActive);
  };

  return (
    <div>
      <p>Address: {getFormattedAddress()}</p>

Available Methods

When you have the Para client instance, you can access all SDK methods including:
  • getDisplayAddress() - Format wallet addresses
  • isSessionActive() - Check session status
  • exportSession() - Export session for server-side use
  • findWallet() - Find a specific wallet
  • getUserId() - Get the current user ID
  • And many more…

​
Example: Advanced Usage

function AdvancedClientUsage() {
  const para = useClient();
  const [sessionInfo, setSessionInfo] = useState<string>("");

  const exportCurrentSession = () => {
    if (!para) return;
    
    // Export session without signers for security
    const session = para.exportSession({ excludeSigners: true });
    setSessionInfo(session);
  };

  const checkUserDetails = async () => {
    if (!para) return;
    
    const userId = para.getUserId();
    const authInfo = para.authInfo;
    
    console.log("User ID:", userId);
    console.log("Auth Info:", authInfo);
  };

  return (
    <div>
      <button onClick={exportCurrentSession}>Export Session</button>
      <button onClick={checkUserDetails}>Check User Details</button>
      {sessionInfo && <p>Session: {sessionInfo.substring(0, 50)}...</p>}
    </div>
  );
}

Notes

  • The client is undefined until the ParaProvider is fully initialized
  • Always check if the client exists before using it
  • The client instance is the same one passed to the ParaProvider
