# 3 Cross-Chain DEX Aggregator The Cross-Chain DEX Aggregator is one of Astarter’s four core modules, designed to connect liquidity and users across multiple blockchain ecosystems. Built on Cardano and progressively expanding into EVM-compatible and other ecosystems, the aggregator provides a unified and efficient trading experience by consolidating liquidity from various decentralized exchanges and enabling seamless asset swaps across chains. Astarter’s Aggregator goes beyond the limitations of single-chain DEXs by combining liquidity aggregation, cross-chain interoperability, and smart routing into a unified platform. This ensures users benefit from best execution, reduced slippage, and a simplified trading experience, while developers and ecosystem partners gain access to broader liquidity markets. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
