Hardware products

• status-keycard
  Keycard is an implementation of a BIP-32 HD wallet running on Javacard 3.0.4+.

• keycard-shell
  Keycard Shell transforms any Keycard into a standalone modular hardware wallet with built-in keypad, display, camera, and USB. Fully open-source and EAL6+ certified, it uses ERC-4527 and UR2.0 QR codes for secure signing. Can be used fully airgapped.

Software wallets

• status-desktop
  Status desktop built with nim and Qt

• status-mobile
  Status mobile built with go and Clojure

• walleth
  Android mobile wallet for Ethereum

• keycard-connect
  Keycard Connect's main function is to enable using the Keycard with dApps outside of a web3 browser using WalletConnect. The dApp must of course support WalletConnect for this to work. Additionally, this app is a little toolbox for Keycard, allowing things like changing PIN, initializing cards, changing seed etc.

Other applications

• keycard-exit
  Mobile application on Android and iOS to store operators on Keycard Multipass and login the operators dashboard when accessed through a web browser.

• keycard-desktop
  Keycard Desktop application to manage your Keycards (not a wallet).

• keycard-ticket
  Keycard Ticket is a prototype dApp which can be used as a ticketing system for events. It works properly only with Status browser, because it uses Keycard Cash Applet which is at the moment supported only in that browser.

• keycard-manager-help
  Closed source tool to manage your keycard, load any applets (cap file), FIDO2 applet, and encrypt decrypt files. On apps store: https://apps.apple.com/iq/app/keycard-manager/id1610328465

• GapSign
  An air-gap Android wallet that uses Status Keycard over NFC to sign Ethereum transactions without the private key ever touching an internet-connected device.

SDKs and CLIs

• keycard-go
  Go SDK for Keycard.

• status-keycard-java
  This SDK simplifies integration with Keycard in Android and Desktop applications. In this SDK you find both the classes needed for generic communication with SmartCards as well as classes specifically addressing Keycard.

• Keycard.swift
  Swift SDK to integrate Keycard with iOS13+.

• keycard-sdk
  Typescript SDK for Keycard.

• keycard-py
  Python SDK for Keycard.

• keycard-cli
  Keycard-CLI is a command line tool to manage Keycards.

• react-native-keycard
  React Native library to interact with Keycard

• shelljs
  Javascript API to communicate with Keycard Shell through USB with websites and through nodejs-based native applications.

• nexum-keycard
  Rust toolkit (SDK and CLI) for interacting with Keycards. Also includes an alloy signer for making use of Keycard in `alloy'

• keycard-nim
  Nim SDK to interact with the Status Keycard

Tools

• keycard-certify
  A tool to create certificates for Keycard manufacturing.

• kshell-updater
  A desktop tool to upgrade Keycard Shell. Not complete yet because it can only download files from a server. Will add selecting local files also. Useful because only chrome-based browser support webhid, so firefox user can use this instead to upgrade keycard Shell.

• keycard-certify
  To create certificates you should first fill in the form, specifying lot number, the quantity of cards for which you need to create a certificate, destination path for the certificates file and choose the output encryption PGP key. You also need a Keycard to sign the certificates. Path m/43'/60'/1581'/2'/0 will be used to sign.

• payment-network-apps
  This repository contains the dApps and SmartContract used for the Keycard Payment Network. The goal of the project itself is to provide the means for using the Keycard as a payment method in retail stores or other non-remote scenarios (i.e: both merchant and buyer are in the same place). The aim is to make purchases using cryptocurrencies as easy and familiar as tapping your card to POS. Note that there is no crypto-to-fiat conversion involved so the scenario we are addressing is where all parties want to use crypto. Beside convenience, the network we are building will have several mitigation measures for unauthorized transactions. While some of these measures are already in place, more are in the works

• keycard-redeem
  This repository contains SmartContracts, dApps and tools to enable using the Keycard Cash applet as a asset redeeming tool. Usage scenario include gift cards, prepaid cards and general distribution of assets. Both ERC20 and NFT are supported. Beside redeeming the asset, in the NFT scenario, the way mappings are created between card and asset can also be useful for user authentication scenario in a context with lower security concerns, such as ticketing for events

• keycard-ledger
  Tentative Ledger application to run a emulated Keycard hardware wallet on Ledger, uses Keycard API over Ledger.

• qrkit
  Reusable library for QR-based airgapped wallet connection and signing flows. Built around ERC-4527 / UR / CBOR — same protocol used by Keycard Shell.
