Anyone can run a raffle. The chain picks the winner.
Permissionless on-chain raffles. Deposit a prize, set a ticket price, let buyers enter from any wallet (or none at all). Switchboard VRF picks the winner. No operator. No “trust us.”

HeliusThree steps. Zero trust required.
Every raffle lives entirely on-chain. The contract holds the prize, mints tickets, calls the VRF, and pays the winner. No operator in the middle.

Creator sets prize, ticket price, and end time. Prize escrows into a PDA vault that no one, not even raffl, can drain.

Every draw is a public, verifiable transaction.
Switchboard signs the random number off-chain and writes it on-chain. Anyone can replay the math.
The protocol can't touch your prize.
Funds sit in a PDA vault that's program-locked. Even raffl admins can't drain it mid-raffle. Refunds run trustlessly if a raffle cancels.
