Last updated 9 months ago

To add a tracking address, you must specify the address itself and the URL for sending notifications about transactions. The address will be monitored on all available networks.

To update the notification URL, you must re-add the address with the new URL.

Notifications are sent once without being sent again.

  "currency": "USDT",
  "network": "ethereum",
  "address": "0x000....",
