Mobile Application
Kairot - Mobile Trading & Investment Platform
A comprehensive cross-platform mobile trading application built with React Native that enables users to trade currency pairs, manage investment portfolios, and earn through referrals with secure KYC verification.
Project Overview
Kairot is a comprehensive cross-platform mobile application built with React Native that enables users to trade currency pairs (USD/CHF, EUR/USD, etc.), manage their investment portfolio, and earn through referrals. The app provides a complete financial ecosystem with features for deposits, withdrawals, trading, and KYC verification.
The application offers a complete financial ecosystem with real-time currency pair trading, investment calculators, and potential earnings displays. Users can securely deposit and withdraw funds with multiple preset amounts ranging from CFA 50,000 to 1,000,000.
Built with modern React Native architecture, Kairot features a modular navigation system with separated stack navigators for each feature module (HomeStack, TradeStack, PairsStack, HistoryStack, ReferralStack). The app implements a sophisticated multi-step KYC verification process with document upload capabilities and personal information collection.
The platform includes comprehensive transaction history tracking for all trades, deposits, and withdrawals with clear status indicators. A built-in referral system allows users to share codes and build teams while earning rewards. The responsive design ensures consistent styling across all screens with custom UI components and smooth animations powered by React Native Reanimated.
