With less than $0.1 in gas fees, you can instantly wipe out market-making orders worth tens of thousands of dollars on Polymarket? Just learned something new—mind blown! A recently exposed new type of attack is severely damaging the liquidity of prediction markets. Attackers exploit the time gap between the platform's 'off-chain matching + on-chain settlement' to initiate doomed-to-fail trades, forcing the counterparty's orders to be cleared. Then, they profit risk-free through 'wide spread monopolization' and 'sniping hedging bots.' With a daily cost of less than $10, they can rake in over $16,000 in profits. Since this is a vulnerability in the underlying architecture, there’s currently no official fix, and market makers are facing the serious challenge of being 'blown up with one click.'
