Why is the draw verifiable?
You do not need to understand smart contracts to play. They matter because they let you—or anyone else—check what happened instead of relying only on Windfall's word.
Entries are recorded on-chain instead of only inside a private operator database.
The draw state and resulting winning numbers can be checked publicly.
The jackpot and draw state are visible from the deployed contracts.
Claims and prize transfers can be independently inspected on-chain.
Your five numbers matter in order.
Windfall evaluates the longest consecutive matching streak in the correct positions. The active winning tier and payout are determined by the deployed contract rules for that draw.
For the exact tier mechanics and protocol details, the technical documentation remains available separately.
Each entry also becomes a ticket NFT.
You do not need to manage the NFT mechanics to play. The NFT simply gives your entry a permanent on-chain identity and supports the protocol's transfer and claim rules.
Advanced NFT, royalty and shareholder mechanics are intentionally kept out of the basic player flow.
