What Is a DEX Aggregator?
A DEX aggregator (or decentralized exchange aggregator) searches multiple liquidity venues to find better execution for token swaps. Instead of picking one pool, swap aggregation compares prices, fees, and depth — the job of a liquidity aggregator — then routes the trade for a better outcome.
The best DEX aggregator experiences feel simple: you choose tokens, and crypto routing does the hard work. On a single chain that means scanning DEXs. Across chains, smart routing also considers bridges and multichain liquidity so blockchain trading is not stuck on one network's books.
How Smart Routing Finds Better Rates
Smart routing evaluates candidate paths in real time. It may split orders, skip thin pools, and prefer venues with deeper multichain liquidity. The goal is low slippage swaps — minimizing the difference between quoted and filled price — while keeping completion reliable.
Relay applies that aggregator mindset to crosschain settlement: sell on one chain, buy on another, with crypto routing that targets payments-grade speed. For users comparing platforms, that combination of DEX aggregator logic and multichain rails is what turns "best rate" into a completed trade.
