Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.aspidanet.com/aspida/how-it-works/duo-token-model.md). # Duo Token Model Aspida's LSD operates on a dual-token model consisting of the wrapped token, aETH (a deposit certificate of native ETH tokens wrapped 1:1 with ETH), and saETH (ERC4626), the staking token representation minted upon aETH staking. Primarily, aETH serves as a means for protocol-controlled liquidity provision, significantly enhancing liquidity efficiency. The amount of saETH staking yield increases as users hold more aETH (with no yield). This dual-token model allows users the freedom to choose the yields they wish to capture, whether from liquidity provision or staking. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.aspidanet.com/aspida/how-it-works/duo-token-model.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
