For example, a user may want to borrow APT on Aptos using only ETH on Ethereum as collateral to secure the loan. In this example, they retain their exposure to native ETH (that is, they do not “bridge” it to Aptos). And they gain leveraged exposure to APT on Aptos. They may then spend this APT anyway they please. The cross-chain money market application makes it very easy for users to permissionlessly enter into new blockchain networks, and interact with their applications, without needing to go through a centralized exchange to acquire the native tokens. --- # 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.concordia.systems/use-cases/cross-chain-money-market.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.
