anchored·2jAajS…N8hYSummary
BurgerSwap is a decentralized exchange (DEX) and automated market maker (AMM) protocol launched in September 2020 on Binance Smart Chain (BSC), built around the native BURGER governance token. On May 28, 2021, the protocol suffered a flash loan and reentrancy exploit that drained approximately $7.2 million in user funds across 14 transactions. Uniswap founder Hayden Adams publicly noted that a critical line of code enforcing the constant-product formula had been deliberately removed from BurgerSwap's fork of Uniswap v2, raising allegations of an intentional vulnerability or insider involvement by the anonymous development team.
