For example, to trade $500 worth of ETH for DAI, the order is routed across four pools: UniswapV2(50%) Kyber (22%) Sushiswap (18%) 0x (10%)Best routing Smart order routing algorithms scan for all possible execution opportunities. For example, if you want to trade sUSD for ETH, a direct sUSD > ETH swap might not be the best option. In this case, it requires an sUSD > USDT/DAI swap and then a USDT/DAI > ETH swap to get the best rates.
