Hi @frznfrg ,
I’m so sorry to hear that. Could you give more information?
- Which wallet did you use? Is it an official one (Daedalus or Yoroi)?
- Do you use hardware wallet to add more protection (Ledger Nano S or Trezor)?
- Did you install Daedalus Android app (scam app) in your mobile?
- Did your computer get hacked?
- Did somebody else know your seed phrase?

If you know the Transaction ID, you could check the detail transaction in Cardano Explorer
