# Payment Guide

> Step-by-step guide for paying with cryptocurrency on KoalaVault

This guide shows you how to complete payments for KoalaVault orders using cryptocurrency exchanges like Binance.

# Prerequisites

Before making a payment, ensure you have:

* ✅ Created an order on KoalaVault (see [Deploy Models](/getting-started/deploy-models#buy-model))
* ✅ A Binance account with USDT balance ([Sign up for Binance](https://www.binance.com))
* ✅ Your order's payment address from the order detail page

<Note>
  **First-time purchase?** We recommend using **anonymous payment**, which allows you to pay directly from exchanges like Binance without transferring to your registered wallet first.
</Note>

# Payment Methods

# Confirm Your Payment

After completing the payment, you need to confirm it on KoalaVault:

    </Tip>
  </Step>

  <Step title="Wait for Verification">
    KoalaVault will automatically verify your payment on the blockchain:

    * ⏱️ **Verification time**: Usually 1-5 minutes
    * ✅ **Automatic**: No manual approval needed
    * 🔍 **Transparent**: Track on [BscScan](https://bscscan.com/)

    Once verified, your order status will change to **Paid** and the model will be available for deployment.
  </Step>
</Steps>

# Troubleshooting

### Payment Not Confirmed

**Issue**: Payment sent but order still shows as unpaid.

**Solutions**:

1. Wait 5-10 minutes for blockchain confirmation
2. Verify you sent to the correct address
3. Check you used BSC network (not other networks)
4. Ensure you sent the exact amount
5. Contact support if issue persists

### Wrong Network Used

**Issue**: Sent USDT on wrong network (e.g., Ethereum instead of BSC).

**Solution**: Unfortunately, funds sent to wrong network cannot be recovered. Always double-check the network before sending.

### Insufficient Amount

**Issue**: Sent less than the order amount.

**Solution**: Send an additional transaction for the remaining amount, then submit both transaction IDs to support.

### Transaction Stuck

**Issue**: Transaction pending for a long time.

**Solutions**:

1. Check blockchain explorer (BscScan) for transaction status
2. If pending, wait for network confirmation (can take up to 30 minutes during high congestion)
3. If failed, try sending again
4. Contact your exchange support if funds were deducted but transaction failed

# Payment Security

### Best Practices

* ✅ Always verify the payment address before sending
* ✅ Send a small test transaction first for large amounts
* ✅ Use two-factor authentication (2FA) on your exchange
* ✅ Keep transaction IDs for your records
* ✅ Only use official KoalaVault website

### What KoalaVault Does NOT Do

* ❌ Never asks for your private keys
* ❌ Never asks for your exchange passwords
* ❌ Never initiates withdrawals from your wallet
* ❌ Never requests payment to personal accounts

<Warning>
  **Beware of Scams**: Only use payment addresses shown on the official KoalaVault website. Never send funds to addresses received via email, social media, or messaging apps.
</Warning>
