These transaction sequences are specified in the relevant `submit` call and checked and executed by the vault. ### Constraints on vault operations Both the asset registry and the hooks contract are used to limit what operations can be accepted. In particular, the current iteration of the hooks contract: * Restricts any outgoing allowances for vault tokens to be created as a result of an operation * Restricts the vault value from decreasing beyond a pre-specified threshold * Restricts the types of operations and contracts that are called in those operations to a whitelist --- # 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.aera.finance/v2-archive/concepts/vault-operation.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.
