Universal Market Access (UMA) is a protocol for the development, issuance, and settlement of derivatives for any underlying asset built on the Ethereum blockchain. A user can generate and create smart-contract governed meta-tokens based off of a derivative, and then take a position long or short of that asset without needing to hold the underlying asset. 您可以在 MEXC 博客中找到有關Universal Market Access的歷史、系統功能以及如何使用它的更多信息。
