Failed tasks
When a task fails, cannot be solved or is not solved within 5 minutes, its full charge returns to your balance automatically. You do not need to ask.
Refused requests
Requests refused with an error, such as a wrong key, a low balance or no solver capacity, are never charged.
Wrong answers
Reports of wrong answers are accepted by the API but do not change the charge, because the task was solved and returned.
Top-ups
Top-ups cannot be withdrawn or refunded to a wallet. The balance does not expire and can be used for any task.
Wrong amount or network
Top-ups are matched by their own address and exact amount on TRON (TRC20). A different amount is held for review. Funds sent on another network cannot be detected.
Lost token
The account token is the only way to sign in and cannot be recovered. A balance on an account whose token is lost cannot be returned.
