    World Cup NFT Fantasy

    World Cup NFT Fantasy

    World Cup NFT Fantasy is a prediction-based game

    ...Extending the idea of CryptoFishx we have built an application that anyone can participate and win with the confidence that no one is going to tamper or cheat in the system. Having it on the on chain (on the blockchain) enables us to use smart contracts which are public (anyone can see and read) immutable (once deployed it cannot be changed) code that governs everyone's interactions with the game. Which means, no third party including us can tamper with the data once set. Anyone can confirm that game works as intended by reading the code and the final prize pool is handed over to the winner by code itself so anyone can confirm that is correct.
