Better Rates. Smarter Routes.

DEX Aggregators and Smart Routing

How aggregators scan liquidity and route swaps for better rates � on Relay.

What Is a DEX Aggregator?

How DEX aggregators find the best token swap rates

A DEX aggregator looks across many pools to find a better swap. It checks prices, fees, and depth. Then it picks a path and sends the trade.

You choose the tokens. The router does the hard part. On one chain, that means scanning DEXs. Across chains, smart routing also weighs bridges and cash on other networks.

The win for users is simple: less guesswork and a fill closer to the quote. The win for apps is fewer failed trades and less need to hard-code a single venue.

How Smart Routing Finds Better Rates

Smart routing checks paths as markets move. It may split an order. It may skip thin pools. The aim is low slippage � a fill close to the quote � with a trade that still completes.

Relay uses that idea for cross-chain swaps. Sell on one chain. Buy on another. You get aggregator-style routing with fast settlement across 85+ chains.

If you only use one DEX UI, you only see that venue�s books. An aggregator widens the search so �best rate� is more than a marketing line.

Liquidity Aggregator Edge

One DEX only sees its own pools. An aggregator scans many sources � better prices when markets move.

Multichain Liquidity

Modern aggregators also tap liquidity across chains. Relay routes across 85+ networks so rates are not stuck on one chain.

What to Look for in a DEX Aggregator

Judge the fill, not the ads. Look for clear quotes. Look for routing that can change when markets swing. Look for trades that finish. Look for the chains you actually use.

Relay pairs that routing style with large settlement volume. That helps when you need swaps that work beyond a single DEX screen.
