FAQ

Is this on mainnet

Not yet. raffl is on Solana devnet for v0.1, so nothing costs real money. The program has been audited internally, and mainnet ships after the hackathon.

Do I need a wallet

Yes, but you do not need a hardware or browser-extension wallet. Login with email or Google and Privy mints an embedded wallet on your behalf. If you already have Phantom or Solflare, those work too.

What prizes can I give away

In v0.1: SOL only. SPL tokens, NFTs, and physical prizes are reserved in the program but the create form gates them off until v0.2.

How is the winner picked

A Switchboard On-Demand oracle commits to a future slot, then reveals a 32-byte signed random value. The program reads the first 8 bytes as a u64, computes winner_index = entropy % tickets_sold on-chain, and looks up the matching Ticket PDA. None of this is server-side. See Switchboard VRF.

Can the creator rig it

The creator picks when to draw (subject to request_draw only being callable when tickets_sold >= min_tickets). They cannot pick the random value. The Switchboard oracle is signed in an SGX enclave; the chain verifies the signature; the program re-derives the index. The creator's only griefing power is to never draw at all, which leaves the prize stuck but unrecoverable to anyone (including them).

What if no one buys

If the deadline hits with tickets_sold < min_tickets, anyone can run cancel_raffle. The creator reclaims the prize via reclaim_prize. No fee charged.

What if the creator disappears

If the raffle is Active and under min tickets at the deadline, anyone cancels. If the raffle is in Drawing but the creator never reveals, anyone can cancel after one hour past the deadline. Buyers refund.

If the raffle is sold out but the creator never starts the draw, v0.1 has no recovery path. The funds stay in the vault. v0.2 will add a creator-bonded model with timeouts.

Is it open source

Yes. github.com/meowyx/raffl. The Anchor program is under program/; the website is under web/. The IDL is published on-chain; technical documentation lives under docs/ in the repo and is mirrored on this site.
