by Mostro Mobile app

Take, chat and settle Mostro disputes from your phone.

The mobile app for Mostro dispute solvers. When a trade on the Mostro peer-to-peer exchange goes wrong, a dispute solver steps in. Bosstro brings the admin side of Mostrix to the phone: see the disputes open on your node, take one, talk to the buyer and the seller, and settle it. Built with Flutter and a Rust core, like the Mostro app. Bosstro is for solvers: the operator of a Mostro node has to add your key as a dispute solver first. To buy or sell Bitcoin, use the Mostro app. Key Features: - Pending disputes: every open dispute on your node, live over Nostr - My disputes: take one and follow it until it closes - Private chat with the buyer and the seller, end-to-end encrypted (NIP-44), with images and PDFs - Read the trade chat between the parties when one of them shares its key with you - Resolve: pay the buyer or refund the seller (Read-Write solvers) - Choose your node: Mostro, a trusted community, or your own - Your solver key stays on your device, in Android Keystore-backed storage - Multi-Language: English, Spanish, Italian, French, German, Dutch, and Brazilian Portuguese - Open source: AGPLv3 licensed and fully auditable

Every release is signed with the same key, so it installs over the previous version and keeps your data. <details> <summary><b>Which APK is mine?</b></summary> - **`arm64-v8a` (v8)** targets the 64-bit ARMv8-A instruction set. Practically every phone released since 2016–2017 runs a 64-bit Android, Google Play has required 64-bit builds since August 2019, and recent devices — the Pixel 7 and later, and any phone built on 2023-or-newer Arm cores — are **64-bit only**: they cannot run the v7 APK at all. 64-bit code is also noticeably faster at the elliptic-curve and encryption work the app does. - **`armeabi-v7a` (v7)** targets 32-bit ARMv7-A with hardware floating point. It is for phones with a 32-bit CPU (Cortex-A7/A9/A15 class, roughly 2015 and earlier) **and** for phones whose 64-bit-capable CPU ships with a 32-bit Android — common in budget and Android Go models with 2 GB of RAM or less. - **To be sure:** try v8 first. If Android answers *"App not installed"* or *"package is not compatible with your phone"*, install v7. With a computer, `adb shell getprop ro.product.cpu.abilist` prints the supported ABIs — if `arm64-v8a` is in the list, use v8. - x86 devices (emulators, some Chromebooks) are not covered by these builds. </details> [`bosstro-v0.1.1.aab`](https://github.com/MostroP2P/bosstro/releases/download/v0.1.1/bosstro-v0.1.1.aab) is the **Android App Bundle** for the Google Play Console — the store builds the per-device APKs from it.
