Have I been scammed? Hello dear community, I need a bit of help. I was checking my balance after I bought some ETH on Arbiturm and then I realized that all my USDT disapperaed. I checked my Transactionhistory and found something that I did not do. I apperantly interacted with this contract: [https://arbiscan.io/address/0xfd086bc7cd5c481dcc9c85ebe478a1c0b69fcbb9#code](https://arbiscan.io/address/0xfd086bc7cd5c481dcc9c85ebe478a1c0b69fcbb9#code) and i am not sure if I approved something in the past that can drain my Wallet in the future. I tried looking for approvals but other than buying some ETH and OHM and I dont use a lot of DApps, so thats why I was wondering. Is anyone familiar with the issue. I am certain that the money is gone, but i would like to check my wallet for vulnerabilities and help others not to do the same mistake I did. P.S. I know it seems suspicous posting a Link so if you need more explanation feel free to ask. I will try my best. Thank you in advance.
