TronSwap

A demo of cross-chain atomic swaps: an HTLC smart contract on Tron that interacts with Ethereum, a single config that drives both chains, and a live dashboard that shows each swap step in real time. It includes deploy/test scripts, a small Node backend that streams progress over WebSockets, and a Next.js UI with explorer links—so you can see locks, withdrawals, and refunds as they happen. Built to be simple, reproducible, and easy to adapt to other tokens or networks.

The swap/ project implements cross-chain atomic swaps using matching HTLC contracts on Ethereum Sepolia (ERC-20 with OpenZeppelin SafeERC20/ReentrancyGuard) and Tron Nile (TRC-20 shim with identical function signatures/events), with the EVM swap logic derrived from the 1inch cross-chain logic example and adapted for our HTLC flow. Hardhat + Ignition handle EVM deploys; TronWeb scripts handle Tron. A single config.json (plus env vars) drives RPCs, keys, addresses, confirmations, timelocks, and Tron feeLimit. A Node/Express backend runs the same test runner used in CI and streams WebSocket events (approval→ lock→ withdraw/refund), while a Next.js + Tailwind dashboard renders live progress, logs, and Etherscan/TronScan links.
