Monad Time Vault

Built an on-chain time capsule on Monad Testnet. Write a secret message, pick a future unlock date, and seal it on the blockchain forever. The message stays hidden until the unlock date arrives — then anyone can read it. Built with React + ethers.js on Replit, smart contract written in Solidity and deployed via Remix IDE. No prior Web3 experience, just vibe coding and figuring things out along the way.
