I present how MEV bots exploit fast-finality L2s by flooding them with reverted swap transactions. After Dencun, cheap gas made it optimal to split arbitrage across many small, redundant trades. 80% of reverts are Uniswap swaps—mostly USDC-WETH—and rarely use PFAs. Instead, bots race for top-of-block inclusion, revealing the fragility of fee-based ordering under sub-second block times.
