- TypeScript throughout

## 🚦 Quick Start

### Prerequisites
- Node.js 20+
- Docker and Docker Compose
- Foundry (for smart contracts)
- PostgreSQL 15+

### Installation

1. **Clone the repository with submodules**
```bash
# Clone with submodules (recommended)
git clone --recurse-submodules <repository-url>
cd asle

# Or if already cloned, initialize submodules
git submodule update --init --recursive
```

2. **Set up environment variables**
```bash
cp backend/.env.example backend/.env
cp frontend/.env.example frontend/.env.local
# Edit .env files with your configuration
```

3. **Start infrastructure**
```bash
docker-compose up -d postgres redis
```

4. **Set up database**
```bash
cd backend
npm install
npx prisma migrate deploy
npx prisma generate
```

5. **Deploy contracts** (see [DEPLOYMENT.md](./DEPLOYMENT.md))

6. **Start backend**
```bash
cd backend
npm install
npm run dev
```

7. **Start frontend**
```bash
cd frontend
npm install
npm run dev
```
