A full-stack, peer-to-peer coinflip betting game on Solana

A full-stack, peer-to-peer coinflip betting game on Solana. Players connect a wallet, create or join on-chain game rooms, and compete head-to-head for 2× the stake. The UI updates in real time over WebSockets, outcomes are resolved on-chain with Orao VRF, and the backend tracks rooms, chat, and match history in MongoDB.

I open-sourced coinflip-casino for developers in Solana / Anchor smart contract development. This post walks through what it does, how the pieces fit together, and how to run it locally.
