The project implements smart contracts on Sui network and frontend needed for interacting with the Sui contracts that enable integration with 1inch on Ethereum or possibly other networks.

We built a comprehensive cross-chain atomic swap application that enables trustless asset exchanges between Sui and Ethereum blockchains using Hash Time Locked Contracts (HTLCs).

1. Smart Contract Infrastructure Sui Move Contracts: Implemented escrow and hashlock contracts on Sui blockchain HTLC Protocol: Built atomic swap contracts supporting both regular and hashlock-based escrows Multi-asset Support: Handles SUI tokens, NFTs, and custom objects

2. Full-Stack Application Backend API: Node.js server with PostgreSQL database for indexing blockchain events Event Indexer: Real-time monitoring of escrow creation, claims, and timeouts Frontend Application: React-based UI for creating and managing atomic swaps

3. Core Features Create Swaps: Lock assets on Sui with secret hash commitment Claim Interface: Reveal secrets to claim cross-chain assets Swap Management: Track active, completed, and expired swaps Wallet Integration: Seamless connection with Sui wallet ecosystem

4. User Experience Intuitive Interface: Clean, accessible UI with proper form validation Real-time Updates: Live status tracking of swap progression Demo Functionality: Built-in demo features for testing and onboarding Responsive Design: Mobile-friendly interface using Radix UI components

We built a full-stack atomic swap platform with three core layers: smart contracts on Sui, a Node.js indexing backend, and a React frontend, all connected through real-time event monitoring and cryptographic hash commitments. Smart contracts are written in Sui Move, deployed on Sui testnet. Backend API for indexing Sui network events is written in node.js + Prisma ORM database. Frontend written in React and Typescript implementing Radix UI and Tailwind CSS.
