How Smart Order Routing (SOR) Minimizes Market Slippage

When executing market transactions, the naive approach is to route the entire trade into the largest recognized pool. However, Constant Product Market Maker (CPMM) formulas dictate that price impact grows exponentially with trade size relative to pool reserves.

Smart Order Routing formulates order routing as a convex optimization problem. Given an order size X, the router calculates the optimal marginal contribution across multiple pools (Pool A, Pool B, Pool C) such that the marginal slippage across all venues is balanced.

Furthermore, the router evaluates multi-hop routing paths—for instance, converting Asset A to Asset B via an intermediate high-liquidity token Asset C when direct pair liquidity is thin.

Through programmatic multi-split routing and continuous gas cost balancing, institutional traders achieve noticeably superior net fill prices.
