When your trade is sufficiently large, making it on any one exchange might not get you the best possible trade. Slippage can eat away at your return value, and it might be cheaper to make a few trades across a few DEXs. This sounds pretty tedious though...
Using an exchange aggregator, of course! These protocols check everything for you to get you the best exchange rate:
- Spot price
- Trade routing
- It might be cheaper to go from A->B->C than A->C
Different aggregators use different strategies for finding you the best price, so it's worth exploring your options. In some cases, 3rd party aggregators can be even more efficient than order routers provided by the primary trading protocols.
