PolyJackpot.fun is a centralized global Jackpot platoform built on Base Sepolia Tesnet
It leverages **Pyth Entropy** to generate secure, on-chain randomness for both its weekly mega-jackpots and its guaranteed weekly raffle winner.
By utilizing Pyth’s high-fidelity entropy, we’ve eliminated the need for “black box” off-chain random number generation, providing a truly “Live Authority” gaming experience that any user can verify on-chain.
What It Does
PolyJackpot.fun addresses the centralized trust deficit in traditional lotteries by automating entry, draw execution, and payout logic entirely on-chain.
It features a $2.00 entry ticket where
- 80% of the pool goes to the Jackpot
- 10% to a guaranteed weekly raffle winner
- 10% to development
All orchestrated via a :
- NextJs frontend using Privy creating a embedded wallet for Social (x) and wallet connection
- Robust NestJS backend : async module that sync database and blockchain
- Base Sepolia smart contracts : stores every tickets bought, logs entropy numbers for every draw
- For now : manual execution of the draw. It can be only made by 0xF2a1407dc74F8adECC93c3a46b619a871D782d41 (only this addres can add more admins)
- There is a faucet : every user can request 2 testnet usdc and eth that will be transfered automaticaly
