We also offer a generalized formalization encompassing other potential scenarios in Appendix B. In addition to the standardized scenario discussed above, real-world applications of leverage staking can vary significantly among users. For instance, a user might choose not to reinvest all of their received stETH on Aave. For a more detailed exploration of this variability, please see the generalized formalization in Appendix B.
