Full Definition

A DEX aggregator is a protocol that sources liquidity from multiple decentralised exchanges to find the optimal swap route and best execution price for a token trade. Examples include 1inch, Paraswap, and 0x. In payment processing, DEX aggregators ensure merchants receive the best exchange rate when customer payments in various tokens are converted to the settlement currency, minimising slippage and maximising value.
