In August 2025, Turkish CEX BtcTurk suffered a second major hack, with $48M drained from hot wallets across 7 blockchains (Ethereum, Avalanche, Arbitrum, Base, Optimism, Mantle, Polygon) after private keys were compromised.

The Turkish cryptocurrency exchange BtcTurk has reportedly suffered another hack. BtcTurk acknowledged “unusual activity” in its hot wallets and has suspended deposits and withdrawals. However, the exchange did not disclose further details regarding the scale of the attack.
