Primarily used to keep track of positions, as well as acting as the interface between users and markets. ### Accountant A contract that lives alongside a Market contract and is used to do the math necessary to run value transfer events; as well as other math heavy operations. ### Value Providers Each Value Provider contract tells the market what the latest value of an asset is. The value provider is used by the market to determine how the value of an asset moved, and to calculate how to transfer funds between the long and short positions. ### Position Token The ERC721 contract that creates and burns position tokens when positions are opened and closed. ## Off-Chain Reporting Oracle ### Open Markets Oracle This contract is a catch-all data repository for Mimicry Market data feeds. Our community can use this contract to write new data feeds on chain from secure sources, such as Gelato's web3 functions. --- # 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.mimicry.org/for-devs/contracts-and-wallets/contracts-overview.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.
