    CoinStack Wallet — internal cryptocurrency wallet on FlutterFlow

    Hybrid Mobile Apps
    CoinStack Wallet — internal cryptocurrency wallet on FlutterFlow — example of freelancer's portfolio work in category Hybrid Mobile Apps
    CoinStack — a mobile crypto wallet on USDT (TRC-20), made on FlutterFlow with a backend on Supabase/PostgreSQL. The user can deposit and withdraw funds, make P2P transfers within the app, view the balance, and detailed transaction history. The ledger is built on "mirror" transactions (in/out), ensuring transparent accounting and reconciliation.
    The wallet implements staking: freezing of funds, reward accrual on a schedule, automatic status transitions (pending/active/complete) through SQL triggers and background functions. Notifications for important events, staking management screens, and a flexible fee system (fee grid + network) are provided. Stack: FlutterFlow, Supabase Auth, Storage, SQL views, and triggers.
