Project Description

Twenty1 is a Telegram mini app where you can play the classic game of Blackjack with on-chain gameplay and encrypted data. Players can stake money and play against the dealer, earning double their stake when they win. The app ensures fair play through transparent blockchain technology, providing a secure and trustworthy gaming experience.

How it's Made

We built the frontend using the React as well as Node.js framework and styled it with Tailwind CSS. The smart contracts were developed, tested, and deployed using Foundry and Solidity, ensuring a secure and reliable blockchain setup.

Our project is deployed on both Flow and Oasis, and it supports the use of the Dynamic wallet for seamless user interactions.
