Blockenthu

Blockenthu is a cross-chain DEX aggregator that solves the fragmentation problem in DeFi by enabling seamless token swaps across multiple blockchains through a single interface. Built extensively using 1inch APIs, our platform aggregates liquidity from various DEXs and finds optimal swap routes across chains.

Key Features:

• Multi-chain swap support (Ethereum, Polygon, Arbitrum, Optimism, BSC, Avalanche, and more)
• Extensive 1inch API integration for swap execution, price feeds, and market data
• AI-powered route optimization for best rates and lowest fees
• One-click cross-chain swaps with automatic bridging
• Real-time price comparison across multiple liquidity sources
• Gas optimization and slippage protection

The platform addresses critical pain points in cross-chain trading:

• Eliminates need to manually bridge tokens before swapping
• Reduces transaction fees through intelligent routing
• Provides unified access to fragmented liquidity across chains
• Simplifies complex cross-chain operations into single transactions

Built for the Unite DeFi hackathon, Blockenthu demonstrates the power of 1inch's infrastructure in creating next-generation DeFi applications that make blockchain interoperability accessible to everyone.

Blockenthu is built as a comprehensive DeFi application that extensively leverages the 1inch ecosystem:

1inch API Integrations:

• 1inch Aggregation API: Powers our core swap functionality across all supported chains
• Price API: Provides real-time token prices and market data for route optimization
• Balance API: Fetches user wallet balances across multiple chains
• Token API: Accesses token metadata and contract information
• Limit Orders API: Enables advanced trading features
• Cross-chain Swap (Fusion+): Facilitates seamless cross-chain transactions

Technical Stack:

• Frontend: React/Next.js with Web3 wallet integration (MetaMask, WalletConnect)
• Backend: Node.js/Express API server for route optimization
• Smart Contracts: Solidity contracts for cross-chain messaging and token handling
• Cross-chain Infrastructure: Integration with LayerZero, Axelar, and Wormhole protocols
• Database: Redis for caching swap routes and prices

Architecture:

1. SwapManager orchestrates all swap operations
2. RouteOptimizer uses 1inch APIs to find best paths across chains and DEXs
3. CrossChainBridge handles token bridging when needed
4. TransactionMonitor tracks swap progress across multiple chains

Key Technical Achievements:

• Implemented intelligent routing that compares direct swaps vs. bridge+swap paths
• Built real-time price aggregation from 1inch APIs across 10+ chains
• Created unified UX that abstracts blockchain complexity from users
• Developed gas optimization algorithms using 1inch price data
• Integrated with multiple bridge protocols for maximum cross-chain coverage

The project showcases how 1inch's robust API infrastructure can power sophisticated DeFi applications that push the boundaries of blockchain interoperability.
