What is a DEX aggregator?
A DEX aggregatoris software that scans dozens of decentralized exchanges (Uniswap, Curve, Balancer, PancakeSwap, etc.) in real time, then routes your trade — often splitting it across multiple pools — to give you the best possible price. Without one, you'd have to manually compare prices on every venue and pay multiple gas fees to execute.
How ParaSwap aggregates liquidity
ParaSwap uses the ParaSwap (Velora) aggregator API, one of the most established routing engines in DeFi, with billions of dollars in lifetime trading volume. Every quote you see in the swap card has already been compared across 100+ on-chain liquidity sources, with optimal split ratios computed on the fly.
Why use an aggregator instead of swapping on Uniswap directly?
- Better prices — for any trade above a few hundred dollars, splitting across multiple pools almost always beats a single-pool swap.
- Token coverage— long-tail tokens that aren't on Uniswap may have liquidity on Curve, Balancer or a smaller AMM, and an aggregator finds it for you.
- One transaction — even when your trade is routed across 4 different DEXs, you sign one transaction and pay gas once.
- MEV protection — ParaSwap actively works to minimize sandwiching by tightening price impact checks and routing efficiently.
Aggregators we benchmarked against
ParaSwap, 1inch, 0x / Matcha, CoW Swap, OpenOcean, KyberSwap. All are excellent products. ParaSwap settled on ParaSwap as the underlying engine because of its deep integration count, partner-fee program, and consistent routing quality across all 7 chains we support.
