Permissionless on-chain raffles on Solana. Try one in 30 seconds.
Every raffle on the internet asks you to trust someone. Trust the streamer to actually pull a name. Trust the platform's "random" backend. Trust that the prize even exists.
raffl deletes that whole stack. A creator escrows a prize, opens it up at a ticket price, and walks away. People buy in with email or a wallet. When the timer hits zero, Switchboard's verifiable random function picks the winner on-chain. The vault pays out in the same transaction. Nobody can rig it. Including the creator.
A monetized giveaway. A creator wants to give one fan something real, say $1,000 in SOL. They put up the prize from their own funds and open the raffle at $5 tickets. Five hundred fans buy in. One walks away with $1,000. The creator collects $2,375 in ticket revenue (after the 5% protocol fee). The creator spent nothing net, and turned an audience moment into a real win for one fan.
A self-fundraiser without a payment processor. Someone in your community is in a bad spot. They put up a small prize (say $200 they already own) and run a raffle for themselves. Tickets are $10. Five hundred people pitch in to help. The winner gets the $200. The person fundraising walks away with $4,750 to cover what they actually need. No GoFundMe taking 8%, no PayPal freezing the account, no platform owning the relationship.
The fastest path from "what is this" to "I'm in":
- Visit raffl.fun.
- Sign in with email, Google, or a Solana wallet.
- Grab some devnet SOL from the faucet. A quarter of a SOL is plenty.
- Browse open raffles and buy a five-dollar ticket, or click "Start a raffle" and run a small one yourself.
Five minutes from cold start to "I just won (or lost) a real on-chain raffle."
- Nobody can rig it. Switchboard VRF picks every winner on-chain. The prize sits in a per-raffle vault that even the creator can't drain early. Anyone can verify the math after the fact.
- No crypto wallet required. Email, Google, or your own wallet. raffl mints embedded Solana wallets for users who don't have one.
- Refunds if it doesn't fill. Buyers pull their own money back from the vault. No support ticket, no chargeback, no waiting.
- Internally audited (May 2026). Three findings, all fixed before deploy. Mitigations in the program docs.
A real raffle that ran on the live system: 0.50 SOL prize, 0.05 SOL tickets, recent buyers visible on-chain.
raffl is v0.1, devnet-only. What that means:
- Prizes are SOL only. SPL tokens, NFTs, and USDC arrive in v0.2.
- The protocol fee is 5%, capped at 20% by the program itself.
- Mainnet ships post-hackathon. Soon, not "tomorrow."
- A few edge cases lack automated recovery today. v0.2 adds force-settle, claim timeouts, and SPL token prizes.
Architecture and v0.1 deep-dives in docs/architecture.md.
Program: Anchor 1.0.1 (Rust 1.89), Switchboard On-Demand for verifiable randomness, LiteSVM for in-process tests (sub-second, no validator).
Frontend: Next.js 16 with React 19 and Tailwind v4, @solana/kit with a Codama-generated typed client.
Partners: Switchboard provides the on-demand VRF that picks every winner. Helius provides the RPC. Privy handles auth and the embedded wallets that let non-crypto users in.
