Privy Popup Blocking

Browser popup blocking can affect users using social login (Privy) when operations delay the signing popup.

Problem

When using Privy for social login (cross-app connection), browsers may block the confirmation popup if there's a delay between user action and popup trigger.

What Causes This

• Fetching data after button click

• API calls before signing

• Any async operations between click and popup

Solution

Pre-fetch Data Before Transaction

Ensure all required data is loaded before the user clicks the button:

// ✅ Good: Pre-fetch data
const { data } = useQuery(['someData'], fetchSomeData);
const sendTx = () => sendTransaction(data);

// ❌ Bad: Fetching data during the transaction
const sendTx = async () => {
  const data = await fetchSomeData();  // This delay causes popup blocking
  return sendTransaction(data);
};

Best Practices

1. Load Data Early

// Load data when component mounts or when form changes
const { data: gasPrice } = useQuery(['gasPrice'], fetchGasPrice, {
    staleTime: 30000 // Cache for 30 seconds
});
// Transaction handler is instant
const handleTransaction = () => {
    sendTransaction({
        gasPrice,
        // ... other pre-loaded data
    });
};

1. Show Loading States

const MyComponent = () => {
    const { data, isLoading } = useQuery(['requiredData'], fetchData);

    return (
      <button 
        onClick={() => sendTransaction(data)}
        disabled={isLoading}
      >
        {isLoading ? 'Preparing...' : 'Send Transaction'}
      </button>
    );
  };

1. Avoid Async in Click Handlers

// ❌ Avoid
onClick={async () => {
  const result = await someAsyncOperation();
  sendTransaction(result);
}}

// ✅ Better
onClick={() => {
  sendTransaction(preLoadedData);
}}

Testing

To test if your implementation avoids popup blocking:

1. Use social login (Privy)

2. Click transaction buttons

3. Popup should appear immediately

4. No browser blocking warnings

Common Scenarios

• Form submissions: Validate and prepare data before submit button is enabled

• Token approvals: Pre-fetch allowance amounts

• Multi-step transactions: Load all data for subsequent steps upfront
