MetaChess

A Play2Earn + Donate DApp.
This was submitted for ETH Shangai Hackhathon.

MetaChess is a DApp built with TypeScript, React and Solidity.
It enables users to enjoy a chess game whilst promoting a positive social impact project on the blockchain.

• The MetaChess DApp spins up an instance where 2 players must pay a challenge fee (contribute to a pot) to play.
• A smart contract acts as an escrow/proctor and monitors the game.
• When the game ends, the smart contract awards the winner 90% of the total pot amount.
• It also sends a donation fee (10% of the total pot amount) to the charity's address.
