How to Donate: Understanding MetaMask Popups

Making your first donation on our platform? This guide explains exactly what to expect during the donation process, including the important two-popup system.

Before You Start

Make sure you have:

  • MetaMask installed and set up on Polygon network

  • POL tokens (for gas fees)

  • USDC tokens (for donating)

The Two-Popup Donation Process

⚠️ CRITICAL: You will see TWO MetaMask popups when donating

This is normal and required for all donations. Here's what happens:

Popup 1: Token Approval

  • What it says: "Approve" or "Allow [website] to spend your USDC"

  • What it does: Gives our website permission to access your USDC tokens

  • Gas fee: Small fee (usually under $0.50)

  • You must: Click "Confirm" to proceed

Popup 2: Donation Transaction

  • What it says: "Confirm" transaction

  • What it does: Actually sends your donation

  • Gas fee: Small fee (usually under $0.50)

  • You must: Click "Confirm" to complete donation

Step-by-Step Donation Process

  1. Enter donation amount on the campaign page

  2. Click "Donate" button

  3. First popup appears - Click "Confirm" to approve token access

  4. Wait a few seconds for the approval to process

  5. Second popup appears - Click "Confirm" to send your donation

  6. Wait for confirmation - You'll see a success message

Total time: Usually 5 to 10 seconds

Gas Fee Settings

When each popup appears:

  1. Look for gas fee options (usually shows "Market" by default)

  2. Click "Market" to see other options

  3. Select "Aggressive" for fastest processing

  4. This ensures your transaction goes through quickly

Common Issues & Solutions

"Transaction Failed" Error

  • Cause: Insufficient POL for gas fees

  • Solution: Buy more POL tokens or try again with lower gas fees

"Only One Popup Appeared"

  • Cause: You may have already approved this website before

  • Solution: This is normal - just confirm the second popup

"Donation Not Showing Up"

  • Cause: Network congestion or you only approved the first popup

  • Solution: Wait 30 seconds or check if second popup is still pending

"MetaMask Not Connecting"

  • Cause: Wrong network or wallet issues

  • Solution: Make sure you're on Polygon network and refresh the page

Important Reminders

✅ Always approve BOTH popups - your donation won't work with just one

✅ Use "Aggressive" gas fees - prevents failed transactions

✅ Keep some POL tokens - you need them for gas fees on every transaction

✅ Double-check the amount - transactions can't be reversed
