The $285M Drift Protocol Exploit sparked fresh debate after on-chain investigator ZachXBT criticized Circle over its response during the incident.
Drift, a Solana-based perpetuals exchange, paused deposits and withdrawals after attackers drained more than $220 million, with some estimates pushing losses closer to $285 million. On-chain data showed tens of millions in assets leaving the protocol, including SOL, stablecoins, and other tokens, which were quickly split across multiple wallets.
Security analysts later suggested the Exploit wasn’t tied to a smart contract bug but to compromised administrative private keys, giving the attacker deep access to protocol funds. The event also hit market sentiment, with DRIFT’s price dropping sharply while trading volume surged amid panic.
ZachXBT drew attention to large USDC transfers moving from Solana to Ethereum during the Exploit, arguing that the response came too slowly.
“Millions in USDC moved cross-chain for hours during the exploit with no intervention.”
The criticism focused on how quickly stablecoin flows could be tracked and potentially frozen, especially during active attacks. The situation also unfolded amid a broader rise in crypto security incidents, with multiple hacks in recent weeks adding pressure across DeFi and raising concerns about spillover risks between platforms.
