What is the biggest dex on Cardano?

Could you please elaborate on what you mean by the "biggest dex on Cardano"? Are you referring to the decentralized exchange (DEX) with the highest trading volume, user base, or some other metric? Cardano, as a blockchain platform, supports multiple DEXs, each with its unique features and offerings. Without a specific metric in mind, it's difficult to definitively state which DEX is the "biggest" on Cardano. However, some popular DEXs on Cardano include SundaeSwap, MuesliSwap, and Cardax, among others. It's worth noting that the landscape of DEXs on Cardano is constantly evolving, and new players may emerge or existing ones may gain prominence over time.
