COIN.CZ Wallet First-Time Setup Guide

This guide provides the minimal necessary steps to compile and run the COIN.CZ Wallet application on Android.

---

Prerequisites

• Flutter SDK installed
• Dart available in your PATH
• Android SDK & emulator or a physical device connected
• make installed (for running dependency commands)
• Also change Flutter path in the MakeFile with the local installed required flutter version path.

---

1. Set Up Environment Variables

First, create a .env file to store the necessary environment variables.
You can do this by copying the example file:

cp .env.example .env

---

2. Fetch Native Dependencies

The project relies on native Rust libraries (boltz_rust) that must be compiled locally.
To install Rust and Cargo, run the following command:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

---

The project relies on native libraries that are not included in the repository.
Fetch them by running the following commands from the project root:

make get-gdk && make get-boltz-rust && make generate-bindings

---

3. Generate Code with Build Runner

The project uses code generation to create necessary files.
Run the following command to generate them:

/path/to/your/flutter pub run build_runner build --delete-conflicting-outputs

💡 Replace /path/to/your/flutter with the path to your Flutter binary if not already in your PATH.

---

4. Run the Application

After completing the above steps, you can run the application on Android:

flutter run

---

Notes

• Make sure your emulator or physical device is running before executing flutter run.
• If you run into build issues, try cleaning the project:

flutter clean

---

✨ You’re now ready to use COIN.CZ Wallet on Android!
