# Crypto Payment Guide

# 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:

* Download **Binance** (recommended): [Download](https://accounts.binance.com/register?ref=IHHMIR74)
* If Binance isn’t available in your region, try **Coinbase**: [https://www.coinbase.com/](https://www.coinbase.com/)

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](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.

## Other Ways To Pay

* [Telegram Payment Guide](./telegram) — pay with Google Pay or Apple Pay inside Telegram.
