Let's share a lesson from losing 15000 U in the morning. In the morning, I chased up a coin on Ethereum and then cut it in half after buying it. I wanted to cut my own flesh, so I recharged it back to the Binance exchange. First, I copied the exchange recharge contract from Binance, and then I thought that since I wanted to recharge back to the exchange, I should sell the a0t of this address as well. So I clicked on the redirect from the OK wallet to Uni, only to find that there wasn't much money left, so I didn't sell it. Then I transferred the money. During this process, the OK wallet aggregated it and it automatically copied the contract to Uni, causing the address I copied on Binance to be overwritten by the contract address. I didn't check it (it's all my fault). Then I transferred 8.4 ETH from my wallet to the Ethereum contract address of A0T. Please remember to double check the transfer address, Okay, I also have two suggestions @ star_okx @ Haiteng_okx 1. Can a note be added to the transfer address to save my exchange's recharge address, without having to copy it every time; 2. Converting to a contract address is a better reminder, but it may be a non contract address on the Ethereum main network. anyway， Just a reminder, I'm going to move bricks
