I have already done this and I received the following email, which seems to be a worthless template answer: All deposits and withdrawals on Hotbit are processed by our system automatically. After our verification, there is an error parameters occurs on the chain when your withdrawal sends out by our system automatically, which results in the withdrawal is not completed. Our relevant colleagues have been detecting this problem, we have been following up on this issue, if there is any progress, we will inform you immediately. We apologize for any inconvenience caused. Thank you for your understanding and waiting! Just out of my curiosity, how long does a tx take in Solana Chain? Was the chain congested today?
