Screen.Recording.2025-10-30.at.10.00.28.1.mov

Acceptance Criteria

• The start() method on the wallet-service facade now accepts an optional waitReady parameter that will return early if false (defaults to true). It will return as soon as the wallet is created in the wallet-service and is
• Added a startReadOnly method that will start a wallet facade using the xpubkey new auth mechanism.
• The startReadOnly method will wait until the wallet is ready and fail if it wasn't previously initialized

Checklist

• If you are requesting a merge into master, confirm this code is production-ready and can be included in future releases as soon as it gets merged
• Make sure either the unit tests and/or the QA tests are capable of testing the new features
• Make sure you do not include new dependencies in the project unless strictly necessary and do not include dev-dependencies as production ones. More dependencies increase the possibility of one of them being hijacked and affecting us.
