Bitget CEO Gracy Chen said attackers compromised a backend system in the exchange's wallet infrastructure, spoofed transaction data and triggered its authorization process to move funds out, ruling out a private-key compromise. She said Bitget's user protection fund, which holds over $464 million, covers the loss. Circle's quick action contrasts with its response to April's $285 million Drift hack, when the attacker moved about $232 million in USDC from Solana to Ethereum using Circle's own cross-chain transfer protocol; critics including ZachXBT said Circle could have acted faster to blacklist wallets and freeze funds, and Circle said it freezes assets when legally required.
