✨ Features

• 🔐 Secure Key Management – Generate and manage cryptographic keys securely.
• 📤 Transaction Signing – Sign transactions using native cryptographic libraries.
• 🌐 Blockchain Integration – Interact with blockchain networks directly from Dart.
• 🚀 High Performance – Utilizes Rust for optimized performance and security.
• 🛠️ Cross-Platform – Works on Windows, macOS, Linux, Android, and iOS.

📦 Installation

Add the package to your pubspec.yaml:

dependencies:
  monero_wallet: ^1.0.0

Then run:

dart pub get

---

🛠️ Setup

1. Rust Environment

Ensure you have Rust installed:

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

2. Build Native Library

Navigate to the Rust directory and build the shared library:

cd rust_backend
cargo build --release

This will generate the shared library (.so, .dylib, or .dll depending on your OS).

3. Configure Dart FFI

Place the compiled library where your Dart app can load it. Typically:

• macOS/Linux: rust_backend/target/release/libmonero_wallet.so
• Windows: rust_backend/target/release/monero_wallet.dll

---

🚀 Usage

Initialize the Wallet

import 'package:monero_wallet/monero_wallet.dart';

void main() {
  final wallet = NativeWallet();

  wallet.initialize();

  print('Wallet initialized!');
}

Generate a New Key Pair

final keyPair = wallet.generateKeyPair();
print('Public Key: ${keyPair.publicKey}');
print('Private Key: ${keyPair.privateKey}');

Sign a Transaction

final transaction = "sample transaction data";
final signature = wallet.signTransaction(transaction);
print('Transaction Signature: $signature');
