Puzzle Chain

Puzzle Chain is a decentralized jigsaw puzzle platform built on the Monad blockchain where players solve beautiful puzzles and mint their achievements as NFTs. Every completed puzzle generates on-chain metadata containing puzzle details, solve time, difficulty, piece count, solver wallet, and mint timestamp, creating a permanent and verifiable achievement on the blockchain. Being new to vibe coding and Web3 development, every step of building this project was a learning experience. From writing and deploying Solidity smart contracts to integrating IPFS with Pinata, implementing the ERC-721 NFT standard, connecting MetaMask, handling blockchain transactions, and building a full-stack dApp with React, Vite, and Supabase, I learned something new at every stage.
