The latest release of Jade, version 1.0.31, brings a range of upgrades designed to enhance security, functionality, and user experience. Whether you’re new to Bitcoin or a seasoned cypherpunk, this update represents a significant leap forward in self-custody technology.
Key Features and Improvements
One of the most notable additions in Jade 1.0.31 is the automatic validation of change outputs when signing PSBTs for the ‘Multisig Shield’ feature in Blockstream Green Wallet. This feature ensures that your Bitcoin transactions are precisely executed, giving you confidence that your funds are going where they should. This is particularly beneficial for those managing their Bitcoin holdings or consolidating UTXOs. Jade now clearly highlights when a transaction output is verified as being sent back to the originating wallet.
Another valuable update is the alert system that notifies users if a PSBT or transaction doesn’t require a signature from your Jade device. This feature simplifies the signing process, eliminating unnecessary steps and keeping you in control.
Enhanced User Experience
Jade 1.0.31 introduces several refinements to the user interface. One of the more user-friendly changes is the ability to abandon a PIN entry from the first digit, streamlining the process and enhancing usability. For those who prefer customized setups, Jade now supports 180-degree screen rotation, providing more flexibility in hardware configurations.
For developers and enthusiasts, the update brings a new command-line interface tool, making interaction and testing easier than ever. Additionally, experimental support for esp32s3 devices like the ttgo-tdisplayS3 has been added, broadening the device’s versatility.
Visual and Security Enhancements
The Home and Camera/QRScan screens have been redesigned to improve navigation and readability, ensuring that operations are both intuitive and efficient. On the security front, Jade now locks only when an active serial or BLE connection is lost, rather than when it’s unplugged for charging. This change keeps your device secure without interrupting your routine.
Under the hood, updates to the ESP-IDF base firmware and a shift to the esp_lcd graphics library enhance performance and stability, further solidifying Jade’s reputation as a reliable self-custody tool.
Bug Fixes and Final Touches
Jade 1.0.31 also addresses several bugs, including improved UI scaling on larger DIY displays and better handling of change outputs in registered descriptor policies. Additionally, the correct display of confidential Liquid BTC Taproot addresses during signing ensures top-tier security without sacrificing functionality.
This latest update continues Jade’s commitment to securing your Bitcoin while providing a seamless user experience. With Jade 1.0.31, your tools remain at the forefront of Bitcoin self-custody technology, ensuring that you’re always in control of your financial future.
