MagicGame — SOL Price Prediction Bot on Ephemeral Rollup

A Telegram bot where users predict if SOL price goes UP or DOWN in 30 seconds. Built on MagicBlock's Ephemeral Rollup for real-time, zero-fee onchain game state.

Live Demo

How It Works

1. User sends /start → bot generates a Solana wallet for them
2. User taps Predict → picks UP or DOWN → picks bet amount
3. Bot delegates game state to Ephemeral Rollup
4. 30 seconds later → bot fetches live SOL price via Binance API
5. Bot resolves prediction onchain → winner receives 1.9x payout
