Currently Hush has an Android app on the [Google Play](https://play.google.com/store/apps/details?id=org.myhush.silentdragon) store, but it is a "remote control" and requires a desktop computer to pair a full node. Many people around the world do not own a desktop and only own a mobile device. This has made us rethink our stance on purely mobile wallets, where private keys are stored locally on-device.
This idea would be adding an important feature to https://git.hush.is/hush/SilentDragonAndroid such that the user can create a wallet without connecting/pairing to their full node on a desktop, what is called a "lite wallet". This means generating a "seedphrase" which the user backs up by writing on a peice of paper. That seedphrase is sufficient to recover any private keys of all addresses in the wallet.
This idea would be coding in Kotlin in an established Android App codebase, specifically, to add this Kotlin dependency to the app:
https://git.hush.is/hush/kotlin-bip39 and also a GUI to do the following things:
* Generate a new seedphrase, show to user
* Verify user has written down seedphrase, via choosing words on-screen
* Restore wallet from seedphrase
* Extra credit: Sweep funds from private key in QR code into current wallet
This is an exciting project to port the functionality of [HushChat](https://git.hush.is/hush/hushchat) from our lite wallet into our GUI full node wallet. Currently HushChat Protocol whitepaper is in development and we have a plan for how to migrate code.
HushChat is a decentralized encrypted messaging platform, which is Free Software, and can be "federated" with the public "HUSH mainnet" or people can create their own encrypted messaging platforms on their own servers.
The HUSH [Twitter](https://twitter.com/MyHushTeam) account and [Duke Leto's LinkedIn](https://linkedin.com/in/jaleto) have explanations about HushChat.
Currently we have no mobile wallet on iOS and this project would be to port code from the Zcash project to work with Hush. This would involve changing the code to use the Hush fork of librustzcash and UI/UX changes related to different currency units, documentation, links and disabling transparent address support.
We want our users to have the protections of Tor out-of-the-box, without doing anything extra, like Tor Browser. This task will have students take the latest stable version of Tor at the time, and build a Docker
environment where anybody can easily "spin up" a SD instance which connects to the local Tor middle node running on localhost. At first this project will only target Linux support, but it needs to be written in a way that future support for Mac+Windows is not painful.
Many new improvements related to Tor have been merged into Bitcoin Core recently, which are compatible with
Hush, since we are based on Bitcoin Protocol. These are related to new security and performance improvements,
and relate with, but are independent of, the previous task of SD+Tor.
One is better tracking of Tor nodes, as different from nodes connecting via the local network and another is to prevent Tor nodes from getting banned as easily as other nodes, since they often have much less bandwidth and higher latency.
which is the Hush Full Node, to add support for Tor v3 HS's. This will involve porting code from Bitcoin master branch
at https://github.com/bitcoin/bitcoin , which recently gained support for Tor v3. Currently Hush only supports Tor v2, which is being deprecated by the Tor Network, due to it's susceptibility to attacks.
This task involves coding in C++, and doing network-based tests over Tor to verify things work correctly, which will require running at least two and potentially many nodes to simulate some network conditions. This will be done with various other developers that can help students learn how to setup the environment and run the test suite.
The code would be in SilentDragon at https://git.hush.is/hush/SilentDragon . Specifically, a new tab in the GUI will be created for HushDEX, to allow swapping between HUSH and Monero (XMR). More details can be found here:

This involves coding in C++14 and QT5 GUI framework. QT Creator is an IDE GUI that you can use to create and edit these interfaces: https://doc.qt.io/qtcreator/
Hush uses QT 5.15 currently and does not plan to upgrade to QT6.
