I'll join this initiative
Great to see this initiative getting off the ground, really exciting stuff!
Would you mind issuing a pull request with this template filled in https://github.com/status-im/ideas/blob/master/TEMPLATE.md? This way we can track progress of the idea and it will show up here: https://ideas.status.im/all
@oskarth Yes, I was preparing the pull request. Now it is ready as PR #235
Closing to reflect current issue state.
Summary
We currently have a Javacard based hardware wallet implementation. This is a simple and inexpensive hardware wallet with good security. The main limitations of this solution are
The proposal is to create a Pro version of the hardware wallet not based on the JavaCard platform and removing these limitations. This Pro version will have a significantly higher cost that then JavaCard one, since it will be a more complex device.
Swarm Participants
Product Overview
The product will be a HD hardware wallet with its own screen and input buttons used to display and confirm transactions. The seed will be generated on card and mnemonics will be displayed on the card screen as to never reach the mobile device. Communication with mobile/desktop clients will happen through BLE. The device will be powered by its own rechargeable battery (inductive charger). Ideally, the physical size will match that of a standard smart card.
Security and Privacy Implications
As with any hardware wallet security is a prime concern. The device must be engineered to cope at least with the following threats
Phase 1
Goal Date: Start of Q4 2018 Description: A prototype should be built using an STM32 Nucleo development board with a Bluetooth shield. This will allow writing most of the firmware. During this phase the UI must be designed. This means the design of a custom segment-based LCD and the design of how the user will interact with the device.
Phase 2
Goal Date: End Q4 2018
Description: At the beginning of Q4, the new STM32WB chip will be available. This component integrates a bluetooth stack and a STM32L4 core in a single chip while also providing hw-accelerated encryption and key management. The firmware must be ported to this platform, which will be the platform used by the actual product
Phase 3
Goal Date: TBD
Description: In this phase the final product design, PCB design and BOM must be finalized and a manufacturer must be chosen
Phase 4
Goal Date: TBD
Description: Stock and distribution
