Binance has taken swift action against Flow (FLOW) after a serious exploit hit the blockchain late December. The exchange confirmed it will remove several FLOW trading pairs and place the token on its risk “Watchlist,” a designation reserved for assets with heightened volatility and uncertainty.

The move follows a December 27 hack in which attackers exploited a flaw to mint fake FLOW tokens, triggering a sharp market sell-off and wiping roughly 40% off the token’s value. Binance will delist nine spot pairs, including FLOW/BTC, while flagging FLOW alongside other high-risk assets.

Although Binance did not directly reference the hack, Flow later suggested that an exchange’s AML/KYC lapse allowed stolen tokens to be laundered—fueling speculation within the community. Meanwhile, the Flow Foundation says it is close to fully restoring the network after the $3.9 million breach and plans to publish a full post-mortem soon.

Binance also disclosed that it has frozen remaining hacker funds on its platform and urged Flow to avoid any blockchain rollbacks that could disrupt user balances.
