Getting Started

Simplicity is a cross-platform cryptocurrency wallet application that provides secure and intuitive management of your digital assets. This guide will walk you through the setup process and core functionality.

Installation

Prerequisites

Before installing Simplicity, ensure you have:

  • Flutter (latest stable version)
  • Platform-specific development tools:
    • Android: Android Studio and Android SDK
    • iOS: Xcode and CocoaPods
    • Desktop: Windows, macOS, or Linux development tools

Installation Steps

  1. Clone the repository:

    git clone https://github.com/yourusername/simplicity.git
cd simplicity

  2. Install dependencies:

    flutter pub get

  3. Run the app:

    flutter run

First Launch & Onboarding

  1. When you first launch Simplicity, you'll be presented with an onboarding screen that introduces key features:

    • Secure wallet management
    • Send & receive functionality
    • QR code integration
    • Balance tracking

  2. Follow the onboarding screens by pressing "Next" or skip directly to the setup process by tapping "Skip".

Creating Your Wallet

Setting a Password

  1. After onboarding, you'll be directed to the password creation screen.
  2. Create a secure password (minimum 6 characters).
  3. Agree to the terms of service by checking the box.
  4. The app securely stores your password using SharedPreferences.

Wallet Creation

  1. Once your password is set, the app will:

    • Show a loading indicator
    • Connect to the wallet service
    • Create a new wallet account using the WalletClient().createAccount() method
    • Generate and store your private and public keys

  2. Your wallet credentials will be:

    • Backed up locally in the accounts.json file

Backup Your Recovery Phrase

  1. The app will convert your private key to a mnemonic phrase using convertToMnemonic().
  2. Important: Write down this recovery phrase and store it in a secure location. It's the only way to recover your wallet if you lose access to your device.
