Haveno App (Cross Platform)

Norrin Radd requested to merge NorrinRadd/ccs-proposals:norrin-haveno-ios-android into master

What

A cross-platform Haveno application that supports Windows, macOS, Linux, iOS, Android, and web browsers, all within the same codebase. As the milestones mention, all basic functionality of Haveno will be supported through the app. Market statistics are not mentioned in the milestones but can be added in a later proposal. In accordance with CCS rules, all software will be MIT licensed. All payouts are value for value; no payouts without the delivery of the agreed-upon software.

Technology

The Flutter SDK is used to support the 6 different platforms uniformly. Flutter SDK is supported on all major operating systems, enabling other developers to download, build, run, and contribute from their system of choice.

The proposed Haveno app leverages Haveno daemon as a node into the Haveno network of your choice. This proposal includes changes to Haveno daemon that enable easy setup and background execution for compatibility with this app. Once running, the app UX is mobile and responsive.

Connectivity

Secure connectivity to the daemon is key, as it hosts money and trade actions. TLS is currently implemented. Tor implementation is in progress. Password authorization is present. Daemon certificates are completed, but validation depends on client platform support (validation may vary by platform). Client certificate work is in progress.

For those wishing to host a web interface, scripts will be provided that automate the process as much as possible (cert generation, server setup and teardown, etc.).

Testing

As people know, testing involves running as many permutations of user input as possible. To give an idea, there are 6 supported platforms, 2 connection types, 2 primary offer types, 2 sides to a trade, and tons of options available on each trade (different types of exchange rate settings, triggers, security deposit options), 56 different supported payment methods, etc.

Code coverage will be as extensive as possible. All permutations do not need to be touched, but the ones where there can be obvious problems will be addressed (e.g., Fiat trades are rounded to the nearest whole fiat number, whereas cryptocurrencies are not).

Why

We all know about the Monero delistings. We all see the question constantly: "Where can I buy Monero?"

Haveno is the best exchange that we have that is censorship-resistant, supports on and off ramps, and is relatively private. The better Haveno gets, the easier it will be for everyone to acquire Monero in a private manner that cannot be turned off.

Currently, Haveno is desktop-only. One of the top most-requested features of Haveno is mobile device support. The work in this proposal will decouple Haveno users from desktop computers and allow trading on the go. The increase in ease of use should increase liquidity greatly and satisfy the desire people have to use their mobile devices. Lastly, an alternative UI will be provided for desktop and web interfaces.
