# DEX aggregator

## Definition

A DEX aggregator is a service or smart-contract system that compares or routes trades across multiple decentralized exchanges or liquidity sources.

## What it means in practice

An aggregator can split or route a swap to seek better execution, but the final transaction may involve several contracts and tokens.

## How this concept appears in Terenval Wallet

If a compatible aggregator connects through WalletConnect, Terenval remains the wallet that presents the signing request rather than the service that sets the trade route.

**Important:** Read the final transaction request carefully because routing complexity can make the interaction harder to understand.
