Can you complete the dex without trading?

Could you please elaborate on the concept of completing a decentralized exchange (DEX) without engaging in any trading activities? Typically, DEXs facilitate the exchange of cryptocurrencies and other digital assets, which inherently involves trading. Are you perhaps referring to a specific feature or aspect of a DEX that can be experienced or "completed" without actively participating in trades? Clarifying your question may help me provide a more accurate and informative response.
