Lost coins

When I opened my Harmony Wallet my balance was 0. I checked the transactions history and I could see where my coins were transferred to another address but I didn’t transfer them out of my wallet. Can anyone help me find my coins? Thanks.

Sounds like you were hacked my dude. Seeing a transfer transaction you have no knowledge about is almost undeniable proof, unless you enjoy frequent inebriation ofc.
Be safe and start using a new wallet.
