Flip or Flop

Flip or Flop is a blockchain-based card battle game where cryptocurrency market data directly influences gameplay. Players fight 1v1 using crypto-themed cards (ETH Warrior, BTC Butcher, SOL Assassin, ADA Paladin, AVAX Ranger) whose stats update dynamically with real-time Pyth Network price feeds.

Provably fair randomness is ensured by Pyth Entropy, and players stake ETH to battle, with smart contracts settling outcomes transparently.

Key Features: Live Price Integration: Card stats change with real crypto prices Fair Randomness: Pyth Entropy ensures verifiable fairness Animated Arena: Retro pixel-style battle visuals

This project showcases how decentralized data oracles can create dynamic, transparent, and engaging Web3 gaming experiences.

The game’s frontend is built with Next.js and React for real-time interactivity, styled with Tailwind CSS for a pixel-art aesthetic, and powered by Socket.io for live multiplayer battles. Ethers.js enables seamless wallet and blockchain interactions. On the blockchain side, it integrates Pyth Price Feeds for dynamic market-driven stats and Pyth Entropy for provably fair randomness, with Solidity smart contracts managed via Hardhat handling staking and battle settlements. Technically, it features a dynamic stat system, entropy-based randomness, a hybrid off-chain/on-chain architecture, and real-time multiplayer battles with validated price data using staleness checks and TWAP. Additional systems include automated price updates, a fallback demo mode, sprite-based character animations, and gas-optimized contracts. The project leverages Pyth Network for real-world data and randomness, forming the backbone of its decentralized gameplay mechanics.
