Rafffle

Rafffle is the first permissionless NFT raffle marketplace on Solana. It empowers collectors to win blue‑chip NFTs for a fraction of the floor price while giving creators an instant liquidity option without over‑discounting their assets. Every raffle is enforced by a non‑custodial smart contract so that listed NFTs never leave the owner's wallet until the draw concludes.

The platform is optimised for speed (average draw finalisation in < 400 ms), low fees (0.00001 SOL ticket mint cost), and complete transparency. A progressive‑web‑app shell enables offline browsing and home‑screen install, and viewport‑aware image streaming ensures screenshots look crisp even on 4× retina displays.

Innovative Technologies

• Anchor Framework — type‑safe Rust tooling that accelerates program development and minimises attack surface.
• Next.js 14 App Router — React Server Components and streaming for sub‑second page loads and edge‑cached data fetching.
• Tailwind CSS + shadcn/ui — utility‑first styling and accessible component primitives with automatic dark‑mode support.
• Vercel Edge Functions — server‑side rendering and rate‑limited API endpoints deployed at the network edge for global TTFB < 100 ms.
