Your risk score is used for coin compliance analysis and to reveal and track malicious behavior. Available for deposits and deposits with exchange in BTC, BCH, ETH.

Additional deposit callbacks

You can optionally enable callbacks for these cases:

deposits below the minimum allowed amount
deposits received in a currency different from the currency assigned to the crypto address

These callbacks include the received currency and the deposit address.

In the merchant dashboard, go to Settings and switch to the Callbacks tab.
Under Additional callbacks, click Manage.
Enable one or both of the following options, then click Save changes:
- Deposits less than minimum amount
- Deposits in a currency different from the original address currency

Cross-currency deposits

When a user makes a deposit in a currency different from the currency assigned to the original address, CryptoProcessing sends a callback to your configured callback URL. Example callback:

    "type": "deposit",
    "crypto_address": {
