If you see any transactions sending your coins to another wallet it is likely that you have been hacked or scammed. The three main ways this occurs are being scammed into giving away keys, approving a malicious or faulty contract and having your computer compromised through downloading a malicious file. Being a decentralised exchange, we do not have the power to freeze funds or recover these in any way. We are sorry if this occurs to you and suggest that in the future you use a hardware wallet and a hot wallet, never give out keys and be very careful about what contracts you approve (and revoke doubtful contracts after).
