# Introduction of rUSD rUSD is a **stablecoin** that uses the same mechanism as fxUSD, but with its reserve comprised of only ETH Liquid Restaking Tokens (LRT), starting with Ether.fi’s eETH and Renzo Protocol's ezETH. Even though the risk profile of LRTs are different enough to LSTs that they should not be included in fxUSD, restaked ETH is an excellent use-case for the powerful f(x) mechanism. Stability Pool depositors can earn very high restaking rewards, including points, all without taking ETH price exposure. In fact, since 100% of reserve points flow to the rUSD Stability Pool, along with 50% of LST yields, points accrual in the rUSD Stability Pool is much higher, dollar for dollar, than holding the LST itself! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
