ERC20 Call Back

The ERC20 Callback is specifically designed for handling ERC20 token transactions, such as USDT. Notifications are sent only when the address times out or when a transaction reaches 12 confirmations. If the received USDT amount differs from the required amount, it will be recalculated. The address will time out after 1 hour.
