Verifiable prize competitions
The draw happens in public.
Entries are recorded on a public ledger. When sales close the list is sealed, the winning number comes from the blockchain itself, and the result is there for anyone to check — including you.
Reading competitions from chain…
The ProjectX guarantee
The draw cannot be influenced, repeated, or quietly edited.
- Retrying is impossible. Sui rejects any transaction that places another command after one using randomness, so a “draw, and cancel it if I lose” attempt never executes.
- The draw happens once. A second attempt is rejected by the contract.
- A free entry weighs exactly what a paid ticket weighs. Enforced by the contract, not promised by the promoter.
- Below its minimum, every entrant is refunded in full. The contract holds the money until then, and the organiser cannot take it early.
- The draw does not need the organiser. After the draw time, anyone can trigger it — absence delays a result, it cannot withhold one.
