LML/USDT staking protocol Hack

TOTAL LOST $950K
Low Oracle Manipulation & Price Manipulation bsc

What happened

At the 31 March/1 April 2026 reporting boundary, the LML staking protocol on BNB Chain was exploited for about $950,000 through manipulation of the LML/USDT market and its reward-claim path.

Technical Root Cause

Reward accrual used a stored LML/USDT price protected by a 3600-second cooldown, while redemption depended on the live AMM value; the contract had no deviation check linking those two prices.

Attack Timeline

The attacker used flash liquidity to distort the LML/USDT market, then used EIP-7702 delegation to batch-trigger reward claims from 11 pre-staked EOAs. The resulting LML was sold into the distorted pool after the reward path depleted its reserves.
