Your collateral keeps earning the market's lending yield plus boosted rewards in the form of CRV & CVX. #### crvUSD crvUSD deposited into a CDP on Resupply will be supplied to a lending position of the user's choice on Curve Lend and deposited on Convex Finance. Each lending position will earn the underlying lending fees as well as boosted CRV & CVX rewards. #### frxUSD frxUSD deposited into a CDP on Resupply will be supplied to a lending position of the user's choice on FraxLend. Each lending position will earn the underlying lending fees. ## Minting reUSD Minting **reUSD** against each collateral type will have a maximum Loan-To-Value (LTV) set per lending position as set by governance. In addition, governance will also define a possible maximum borrow limit per lending position as deemed necessary. The minimum amount of **reUSD** that can be minted against a CDP is 1000 **reUSD**. A mint fee for minting **reUSD** is possible but is currently set to zero. This can be turned on later if deemed necessary. ## Borrow Fee Rate The borrow rate for **reUSD** will be set at half the underlying lending fee rate, half the "risk-free rate," or two percent, whichever is greater. **sfrxUSD's** current APY will be used as the oracle to define the "risk-free rate." The borrow rate is then dynamically adjusted up to 60% of the "risk-free rate" or sfrxUSD's APY based on the peg of **reUSD**. This Dynamic off-peg fee goes fully to [Savings reUSD](/resupply-protocol/savings-reusd.md). --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.resupply.finance/resupply-protocol/collateralized-debt-positions.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
