ChainToss is a simple demo smart contract built in Solidity that simulates a coin flip game directly on-chain. Players send a fixed bet amount (0.01 ETH) and guess Heads or Tails. The contract then generates a pseudo-random result — if the player guesses correctly, they instantly win double their bet!
This project serves as an educational example, ideal for beginners learning:
Payable functions
Events
Randomness (and its limitations on-chain)
ETH transfers and balance handling

We aim to make blockchain development more accessible by creating simple, transparent, and educational smart contract examples. ChainToss helps beginners understand key Solidity concepts through real interaction, hands-on testing, and clear code structure.
ChainToss — Simple On-Chain Coin Flip
ChainToss solves this learning gap by providing a clean, minimal, fully on-chain coin flip game. It demonstrates:
How to accept and handle ETH inside a contract
How to emit events for transparency
How pseudo-randomness works (and why it’s unsafe for production)
How to automate payouts
How state variables track results and player interactions
It acts as a practical, interactive tutorial that new developers can deploy, modify, and experiment with.
