🗳️ Pokémon Voting Dapp

A decentralized application (DApp) built on the Sepolia Ethereum testnet that allows users to vote for their favorite Pokémon! Users register with their wallet, name, and a profile image (IPFS hash), and can cast one vote for any Pokémon in the list. The DApp includes admin features for the contract owner to add new Pokémon with their image and name.
