# Haveno & Atomic Swap Multi-Platform Native App for Android, iOS, Windows, MacOS and Linux
**Author**: Kewbit
**Date**: 19/08/2024
## Overview
The Haveno & Atomic Swap Multi-Platform Native App will be an interface for decentralized applications that can connect to the Haveno Daemon, allowing users to conduct transactions in Monero (XMR) using the Haveno decentralized network. The app will be written in Dart/Flutter and will support connections to Trezor and Ledger hardware wallets via secure Bluetooth (for Ledger) and USB (for Trezor) for deposits. Users will be able to buy and sell multiple fiat currencies with their XMR through Haveno. The app will be able through all app stores and installers, or you can build from source.
## Security Considerations
- **Open Source**: All software created will be open-source, and only auditable, open-source libraries will be used. The project will be released under the AGPL 3.0 license upon completion.
- **Tor Integration**: The app will enforce Tor usage, requiring users to connect via a Tor VPN relay (such as Orbot or InviZible). Without a Tor connection, the app will not proceed past the splash screen.
- **gRPC Protocol**: The app will connect to Haveno Daemon using the native gRPC HTTP/2 over Tor (not translated from HTTP/1.2 or HTTP/1)
- **Haveno Integration**: The app seamlessly connect to any Haveno Daemon hosted anywhere (using .onion via Tor)
- **Censorship Resistance**: By abstracting the VPN relay away from the app itself and requiring Orbot or InviZible, we avoid potential censorship issues. The app will not require VPN-enabled entitlements that need signing, thus preserving its censorship-resistant nature. The app will be available on [F-Droid](https://f-droid.org/en/).
- **Secure Device Linking**: The app will support secure linking to a running desktop or server instance via a QR code containing a hashed password in the URI of the Onion Link. [Onion Client Authentication](https://support.torproject.org/onionservices/client-auth/) will be available fro advanced users.
- **Hardware Wallet Support**: The app will allow deposits directly from hardware wallets including Trezor and Ledger.
- **Native Libraries**: The app with use native library per OS directly from trusted sources.
- **Service Segregation**: Each component of the software will run under it's own service on Dekstop versions, you'll be able to manage the services via a System Tray on Windows, Linux and Mac operating systems.
## Features
- Ability to connect to any Haveno network that you want
- Customize based on your locale
- Atomic Swaps seamlessly integrated into offers (BTC -> XMR only, dependant on project status for XMR -> BTC)
- Ability to see Haveno network trade offers
- Start trades, open your own trades
- Chat with the peer trader
- Open disputes if a transaction isn't working out and chat with an arbitrator
- Manage your payment accounts for both crypto & fiat
- Get notifications when your have new trades or chat messages (local notifications that don't depend on Google's push notification system)
- Deposit and withdraw from your wallet
- Beautiful candlestick trading view for Haveno network activity
- System Tray to manage your Tor & Haveno Daemon services, keep your daemon online without the client open for mobile users.
- Docker image will be available for advanced users contingent on colaberative efforts between the Haveno DEX team.
## Possible Future Plans
- Matrix integration for server-side notifications to the mobile device (this might be nessesary for iOS users to get notifications reliably and timely.)
- Design the P2P protcol from Haveno in Dart, so that you may not depend on the Haveno Daemon for the app to work (Standalone Mobile App)
## Purpose
### What the Proposal is About
This proposal aims to bring the Monero ecosystem together through Haveno and Atomic Swaps with a user-friendly, multi-platform app that considers security, censorship resistance, and hardware wallet support.
### Who Will Complete the Proposal
Kewbit (kewbitxmr@protonmail.com)
### Why It Is Important for Monero and the Community
This app is crucial for the Monero community because it promotes a censorship-resistant and decentralised ecosystem. There is great difficulty in finding places to trade XMR due to certain website closures and crackdowns. By making the app available on multiple OS and platforms, including on F-Droid, Play Store, and App Store, we ensure that it reaches a wide audience, including those who prefer non-traditional Android phones using Play Store.

## Expiration Date
I do not intend for there to be an expiration date. I plan to release the app quickly as I am working on it full-time, even before producing a CCS. I see this as an ongoing project but expect to have it done absolute latest by 31st December 2024.
## Alpha Builds
You can check out the alpha builds, source is not currently available to being a bountied project.
