Transaction ordering, particularly through Miner Extractable Value (MEV), significantly impacts decentralized exchange (DEX) arbitrage profitability. Front-running bots exploit pending transactions by submitting higher-fee trades, capturing price discrepancies before legitimate arbitrageurs. This reduces profit margins for honest participants and distorts market efficiency. Back-running and sandwich attacks further exacerbate losses by manipulating transaction sequences. Mitigation strategies like fair ordering protocols and MEV-resistant DEXs aim to level the playing field. By addressing MEV, DEXs can enhance arbitrageur incentives, ensuring tighter spreads and more efficient price discovery across liquidity pools.
