What happened
On August 8, 2026, Atomic Green on Arbitrum was exploited for approximately 29,984 USDC through a signature-replay flaw affecting its leveraged-trading liquidity positions.
Technical root cause
The affected signature design allowed a manager signature to be reused across different Uniswap V3 LP position IDs, enabling unauthorized full LP burns when paired with price manipulation.
How it happened
SlowMist reported that one manager signature could be replayed across 21 Uniswap V3 LP position IDs. The attacker combined those unauthorized LP burns with flash-loan price manipulation.
