NadFlip

When you place a bet using MON, our smart contract requests a secure random number from the Pyth Entropy protocol. The result is used to simulate a coin flip between 1 and 999:

• If you guessed "High" and the roll is 500–999, you win.
• If you guessed "Low" and the roll is 1–499, you win.
• If the roll is exactly 888, you win the entire jackpot pool on top of your payout.

Winnings are instantly transferred to your wallet if you win. All flips are stored on-chain and visible in the flip history.

MON is the native currency on the Monad Testnet. NadFlip is a testnet-only project, meaning all tokens used are free testnet tokens without real-world value.

888 is the jackpot number. If your random roll is exactly 888, you win:

• The regular payout (2x your bet minus fees), plus
• The entire jackpot pool, which grows every time someone flips.

After a jackpot win, the pool resets to zero. Previous jackpot wins are logged on-chain and viewable in the Jackpot History.

Fees are necessary to maintain the game and fund the jackpot:

• 0.2% goes to the developer wallet (to keep NadFlip running).
• 0.8% goes into the jackpot pool, making it grow over time.

These percentages are deducted from the bet amount and are only collected if your flip is valid.

To ensure randomness is secure and tamper-proof, NadFlip uses Pyth Entropy, a decentralized on-chain randomness provider.

This system requires each flip to pay a small gas fee to the Entropy network’s provider, which is separate from NadFlip. This fee is:

• Quoted live from the Entropy contract before each flip.
• Automatically included in your transaction total.
• Forwarded to the provider to fulfill randomness via callback.

The fee is not taken by NadFlip, nor does it affect your payout. However, it is deducted from your total msg.value, so your actual bet amount is msg.value - entropy fee.
