It stores signing keys locally on the phone, handles backup and recovery, and generates signing results after user confirmation. ## Product Role The responsibilities of `Offline Signer` are deliberately narrow: * Store signer private keys * Generate or import signer addresses * Scan or paste signing requests * Complete signing locally on the device * Output signing results for import into the browser extension or web workspace ## Current Entry Points Based on the current repository README, the main sections are: * Home: view device status, a quick signing entry, and recent signing summaries * Keys: manage the local signer list and import or delete private keys * Sign: scan or paste offline requests, validate them, and generate signing-result QR codes * History: inspect details of local signing records --- # 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://wallet-docs.catfee.io/offline-signer.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.
