Crypto Payments

Crypto is the best way to support the project. It’s fast, global, and (when sent correctly) very reliable. We currently support:
  • Bitcoin (BTC)
  • USDC (ETH / BSC / Polygon)
  • USDT (ETH / BSC / Polygon)

​
1. Get An Exchange App (Binance First)

If you don’t already have crypto, start here: Bitcoin is so big now that there are always ways to buy it. If you get stuck in your country, search: “how to buy bitcoin in [country]“.

​
2. Buy Crypto

In Binance or Coinbase:
  1. Buy BTC, USDC, or USDT.
  2. Wait for the purchase to complete and show in your balance.
Tip: If you’re buying USDC/USDT, you’ll choose the network later when you withdraw/send it. Don’t worry about that yet.

​
3. Create A New Invoice

Go to https://dopaminegirl.com/top-up and create a new invoice:
  • Pick Crypto
  • Choose BTC, USDC, or USDT
  • If you chose USDC/USDT, select the network: ETH, BSC, or Polygon
You’ll see a deposit address (and sometimes a QR code) plus the exact amount.

​
4. Send From Binance/Coinbase

In your exchange app, use Withdraw / Send:
  1. Paste the invoice address from the top-up page.
  2. Choose the same network shown on the invoice.
    • For USDC/USDT we support ETH, BSC, and Polygon only.
  3. Enter the amount and confirm.
Important: When sending crypto, make sure the address and network are correct. If you send on the wrong network, it may be lost and can be impossible to recover.

​
After Sending

  • Keep the transaction hash / TXID handy.
  • The invoice updates after confirmations (timing depends on the network).
  • If it hasn’t updated after ~1 hour, contact support with the TXID.

​
Troubleshooting

  • Binance/Coinbase says “wrong address format”? Make sure you picked the same coin as the invoice (BTC vs USDC vs USDT).
  • Network not available? Create a new invoice and choose a network your exchange supports (ETH/BSC/Polygon for USDC/USDT).
  • Sent but not credited yet? Confirm the TXID shows as confirmed on a block explorer, then refresh the invoice page.

​
Security Best Practices

  • Create a fresh invoice for each top-up (don’t reuse old addresses).
  • Verify the first/last characters of the address before you send.
  • Never take “support” DMs on social media—use the email below.
