Adventure Layer Bridge Backend 🌉

A robust backend system for cross-chain token bridging, featuring:

🚀 Key Features

• Multi-Chain Support: Seamlessly bridge tokens between L1, L2, and multiple shard chains
• Real-time Event Monitoring: Listens for deposit events across different chains
• Dual Query Methods: Supports both Graph Protocol and RPC queries for maximum reliability
• Queue-based Processing: Ensures reliable transaction handling with a queue system
• Persistent Storage: MySQL database integration for transaction tracking and state management
• Automated Recovery: Handles network interruptions and failed transactions gracefully

🏗️ Architecture

The system consists of two main components:

1. API Server: Handles external requests and provides system status
2. Listen Service: Monitors blockchain events and processes cross-chain transactions

💻 Technical Stack

• Node.js runtime environment
• Web3.js for blockchain interaction
• MySQL for data persistence
• The Graph Protocol for efficient event querying
• HTTP server for API endpoints

🔧 Configuration

Supports flexible configuration through environment variables for:

• Chain endpoints (RPC/WSS URLs)
• Contract addresses
• Database credentials
• Network parameters

🛡️ Security Features

• Transaction verification
• Duplicate transaction prevention
• Secure key management
• Error handling and logging

🔄 Supported Networks

• Layer 1 (Ethereum)
• Layer 2
• Multiple shard chains

📊 Monitoring

• Real-time transaction tracking
• Block height synchronization
• Event verification
• System status endpoints

⚡ Performance

• Optimized for high throughput
• Efficient event processing
• Minimal latency in cross-chain operations
• Scalable architecture
