# Yield Aggregator ## **What is Yield Aggregator?** We aggregate data on borrowing and lending deals from the Smart Contracts of various Lending Protocols. Our platform organizes and sorts this information to display the best available interest rates, helping you make informed decisions easily and efficiently. ## **Is it safe to perform transactions on Yield Aggregator?** Transactions on Yield Aggregator are safe. All transactions are built and interact directly with the Smart Contract of the protocol you choose. The transactions you perform on the Yield Aggregator platform can be viewed on the Smart Contract of the corresponding protocol, and vice versa. ## **What can I do with Yield Aggregator?** With Yield Aggregator, you can supply assets to earn interest or borrow funds against your collateral. You can withdraw your supplied assets anytime or modify/repay your loan. Any actions you take on the protocol’s DApp are also synced back to Yield Aggregator, ensuring seamless integration. ## **Do the Supply APY and Borrow APR change when I supply or borrow?** It depends on the protocol you choose. In some lending protocols (such as Liqwid, Lenfi), the Supply APY and Borrow APR change based on the balance between the amount of assets supplied and the amount borrowed, known as the utilization rate: * This rate is dynamic and can adjust over time based on the overall supply and borrow within the lending protocol. As more people supply or borrow assets, the rates are updated to reflect the current market conditions. For other protocols (such as Danogo, Optim, etc.), the supply APY and borrow APR will be fixed after you supply/borrow. ## **What is the health factor?** The health factor is a measure of how safe your loan is compared to the collateral you have provided. * High health factor: Your loan is safe, with a low risk of being liquidated. * Low health factor: Your loan is at higher risk; if the value of your collateral decreases or your loan amount increases, you could be liquidated. * Most lending protocols start liquidation when the health factor reaches 1. Simply put, keeping a high health factor helps you avoid losing your collateral when the market fluctuates. --- # 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.
