Case Study: 1WalletWins achieves provably fair onchain raffles with Labrys

1WalletWins launches a fully onchain raffle platform in 8 weeks with Labrys

1WalletWins aimed to build a fully onchain raffle platform where trust and transparency were paramount. The primary challenge was to ensure all raffle mechanics, including provably fair winner selection, were enforced by smart contracts without any backend control, while also providing a simple, mobile-first experience for users unfamiliar with cryptocurrency. Labrys was engaged to address these challenges.

Labrys delivered the complete platform, including smart contracts that used Chainlink VRF for randomness and a mobile web app with integrated wallets. The solution was built end-to-end within an 8-week retainer, resulting in a 100% onchain application where users can participate in raffles with full verifiability. The vendor, Labrys, successfully created a system that aligned user and protocol incentives through a protocol-funded jackpot mechanism.
