Foresight News reports that the DEX aggregation protocol 0x has released a report stating that some propAMMs on the Base network are engaging in systematic quote fraud. Research found that these operators exploit Base's Flashblock architecture, publishing highly attractive prices in the last approximately 200 milliseconds of a block (i.e., the last Flashblock) to lure aggregator routing, but immediately adjust the prices at the start of the next block. Such behavior typically results in traders facing an additional loss of 5 to 10 basis points. Based on a monthly trading volume of 1.1 billions USD, a single liquidity source may cause users to lose up to 500,000 USD per month.Additionally, the report points out that some operators maliciously widen spreads by exploiting the delay between quoting and settlement, or manipulate LP rewards through "phantom liquidity," i.e., depositing large amounts of liquidity before the end of a block and quickly withdrawing it at the start of the next block. This causes aggregators to guide users into higher slippage paths due to incorrect depth data. 0x stated that it currently integrates 5 propAMMs on the Base network, but will continue to monitor execution quality and cut off non-compliant liquidity sources to protect users.
