Arbitrum DeFi platform Futureswap suffers third exploit as $74,000 reentrancy attack follows $395,000 loss

Arbitrum-based leverage trading protocol Futureswap has suffered another exploit within four days, with attackers draining about $74,000 through a newly exposed reentrancy vulnerability in an existing contract. The latest breach follows a separate $395,000 attack on the same contract and a December 2025 governance exploit of at least $830,000, bringing total losses on the platform to over $1 million across three incidents.
