Adapters are upgradable, as they enable interaction with external applications. The Rigoblock protocols requires adapters that communicate with external applications to be explicitly approved. Once an adapter is approved, the adapter methods can be added to the protocol by adding a mapping of selector to adapter. This way, the protocol correctly routes external calls by making the preemptive checks within said adapters. Once an adapter has been added, the governance can remove it by voting. Certain wallets hold governance permit to add-remove methods. Adding and removing methods of preemptively approved adapters does not require governance voting. Things are subject to change as a governance or protocol upgrade could modify these requirements. --- # 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.rigoblock.com/governance/supported-methods.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.
