While many existing arbitrage frameworks depend on antiquated algorithms that fail to navigate the non-linear complexities of current AMMs, particularly those featuring concentrated or asymmetric liquidity, the Arb Fast Lane takes a different approach. Through a process known as Marginal Price Optimization, it successfully detects the most advantageous trade situated at the marginal price frontier. This method ensures complete scalability across every type of AMM or pricing curve. Furthermore, it achieves execution speeds that are 200x faster than legacy counterparts, all while maintaining strict 15-decimal precision for every transaction.
