Hi air, we traced this. The bridge worked and the ETH was not lost.
Dec 16, 2023: you bridged 0.5 ETH with MetaMask Bridge (routed through Across). 0.4953 ETH arrived on ZKsync Era after fees: ZKsync Era Block Explorer
Jun 30, 2026, 13:02 UTC: your wallet sent 0.4940042 ETH to 0x4FbAC3B14984a0141b1b071DeBE622F29958E232: ZKsync Era Block Explorer
Four minutes later, that address forwarded it to 0x91DB5305946446922FfD913bca64F470e590d480: ZKsync Era Block Explorer
The address in step 2 looks like an exchange deposit address. The one in step 3 looks like that exchange’s hot wallet. Your wallet’s key signed the transaction in step 2.
If you sent it: check your exchange accounts for a ZKsync ETH deposit on June 30, 2026. ( we believe it may be OKX based on Nansen tagging.)
Your Ethereum address still holds 0.493 ETH. If you think your wallet is compromised, move it to a new wallet.
Be careful with anyone who DMs you offering to recover funds. That is a common scam.
