    paper blockchain-based poker game

    I built a blockchain-based poker game with a hybrid on-chain/off-chain architecture. The game logic runs off-chain for performance, while settlement and NFT assets are handled on-chain to ensure trust and transparency.

    I’d like to invite you to experience all the features of my blockchain game by visiting the testnet:
    http://43.163.114.175:3001/
    Technically, I’m experienced with Solidity, EVM, and tools like Foundry and Hardhat, and I’ve worked with multiple chains including TRON and Ethereum testnets.
    I see myself as a full-stack architect who can take a product from 0 to 1, and I’m particularly interested in applying my system design experience to Web3 products.
