## Preamble
Idea: 291-hardware-wallet-light
Title: Hardware Wallet Light
Status: In Progress
Created: 2018-08-24
## Summary
We have a Javacard based wallet implementation ready, see https://github.com/status-im/hardware-wallet
This swarm is about making the hardwallet available (uxr, ux, client integration, sourcing) to our Android users.
## Swarm Participants
- Lead Contributor: @guylouis
- javacard: @bitgamma
- Go: @pilu
- Clojure: @gorandjovic @dmitryn
- UXR: @patrick
- UX: @denis-sharpyn

## Product Overview
The product is a HD hardware wallet in the form of a credit card size javacard with contactless capability (nfc), and is natively usable with our android clent.
It will provide extended security and convenience to our users, providing:
- ability to create or import an existing Status account or any BIP-32 wallet onto the javacard
- physically separate the mobile client from its secrets, and allow on-card signature of transactions
- facilitate and secure login onto Status account
### Product Description
Our two priorities for a successfull launch of this product are:
- make no compromise on security
- provide a clear and smooth product experience from setup to the everyday usage of the hardwallet
UXR & UX
- Status hardwallet will be delivered without any software loaded. At first use, the user will be guided through an initialization of his card where the applet will be loaded and two secrets (pairing code of the card, and PUk to recover the card is PIn gets blocked after 3 wrong PINS) will be communicated to him during the initialization process. This initialization happens only once in the life of the card.
- Status user can use their mobile client with hardwallet or no hardwallet. We will guide them through to understand of waht are the implications of using the hardwallet, explaining them where their secrets are stored and how to recover them.
- There are several secrets involved in the full process : pairing code (specific to the card), PUK (specific to the code), PIN code, Wallet key pair, Whisper key pair, and there is a specific uxr @ ux work to make sure the user is not lost in the different informations provided to him
- The user experience is inter-twinned with client integration, since each time a command is set to the card, this one needs to be close to the nfc reader
- the usages to cover are : initialization of the card, setup of an account, signing of transactions, login to status account, javacard life management (change account, unpair card, unblock card)
Client integration
- the usages to cover are : initialization of the card, setup of an account, signing of transactions, login to status account, javacard life management (change account, unpair card, unblock card)
- the intended user experience is that the user will not use his password anymore but a PIN instead. Implications of this have to be studied both on the clients side and javacard side.
- whisper key decouplig dependency. The following swarm is a dependency for the project : https://github.com/status-im/ideas/pull/292
Sourcing
- we are sourcing a credit size javacard with the following characteristics:
- compatible with our applet, supporting 3.0.4 SDK
- (if possible, not fully mandatory) supporting EC end point mutliplication
- contactless (nfc)
- compatible with our app implementation
- we are selecting a supplier or a set of suppliers able to provide to us:
- printing of the card
- realization of a custom packaging + tamper proof seal
- printing of our quick start guide
Security:
- a security audit of the javacard code has been delegated to an external security audit company, this security audit will run through end of october. Since applet software is loaded by our client, the dependency to complete security audit is the actual availability of the beta hardwallet units for beta test.
## Dependency
https://github.com/status-im/ideas/pull/292 is a dependency (whisper key decoupling) for launch
### Phases
Each phase should last 2-3 weeks approx.
PHASE 1
Goal: product outlook defined
UX/UXR/CONTENT Get a ui.v1 screen flows taking into account feedback from uxr,ux, content, dev,security, pm
PACKAGING Get a pack.v1 definition (outlook at this stage) including materials to be used, size, selling technology, type of printing, rough content.
DEV Go-eth work step 1 : define strategy with Nick Johnson regarding PR submitted. Progress on integration.
DEV Installer work step 1 : implementation working in java
SOURCING evaluate other sources the ACS
PHASE 2
Goal: full product specification defined
UX/UXR/CONTENT Get a ui.v2 screen flows taking into account user testing done on ui.v1
PACKAGING/SOURCING Get a pack.v2 definition, by refining our definition and content, and taking into account answers and samples provided by factory to our pack.v1 submission
DEV Go-eth : iteration
DEV Installer : iteration
PHASE 3
Goal: prototype with set-up user experience implemented
DEV UI : get a functional prototype with all set-up user experience
DEV Go-eth : iteration
DEV Installer : done and integrated
UXR/UX/CONTENT/SOURCING: if necessary iterations on user testing and ux/packs definitions
PHASE 4
Goal: alpha release, first feature complete version of the product available
UX/UXR : user testing of phase 3 prototype for the set-up part, provide feedback to reach alpha level
DEV UI : full ux implemented, and take into account feedback from user testing of phase 3 result
DEV Go-eth new step (to be precised)
QA activity starting
SOURCING : user set-up validated + packaging defined, we can pass a purchase order to the factory from here. Lead time to get product : 6 weeks.
UXR/UX/SOURCING: if necessary iterations on user testing and ux/packs definitions
PHASE 5
Goal: beta release, first product ready for deployment to beta users/testers outside status
DEV UI finalization
QA effort
DEV Debugging
SOURCING : validation of final samples
## Exit criteria and Success metrics
This swarm will be deemed successful and be closed after reaching Phase 5 if more than 90% of beta test users score the user experience to more than 4 out of 5
