Dewls is a multi-chain arcade platform that allows users to battle with each other across various games like Rock-Paper-Scissors and Connect 4. The game data is handled on-chain and stored immutably to ensure transparency amongst competitors. Once a winner is decided, they are prompted to sign an attestation to mark their victory into the leaderboard and get a chance to win pool prizes distributed each weekend. This enables users to build a Proof-Of-Victory to showcase their skills. Built at ETHOnline 2024, this project won the Sign Protocol Pool Prize. The platform uses Web3Auth for authentication, Socket.io for real-time game logic, smart contracts deployed on Morph L2, Hedera, and Rootstock, and XMTP for user notifications.
