Yoka

Real-time Asset Duel Trading Platform

Built at Amega

Yoka was a real-time asset dueling platform where users selected financial assets such as Tesla, Microsoft, or Google and competed against other assets based on market price movement. Users placed stakes using USDT or Yokens (an in-app virtual currency) and selected duel durations of 5, 10, 15, or 30 minutes. Outcomes were determined by market profit or loss during the selected timeframe. The platform was delivered as both a Telegram Mini App built with Next.js and a mobile application built with React Native, enabling users to deposit funds via multiple wallets and participate in live duels.

The company was dissolved due to unknown reasons but work that was done is mentioned below along with screenshots.
