Description
Strings Brasil is an innovative mobile application that connects fans and artists through digital coins. Users can buy and sell coins from their favorite artists, use them to purchase exclusive products in our marketplace, and participate in raffles for unique prizes, including autographed items and concert tickets.
The app was initially developed in Angular and later rebuilt in Flutter to enhance performance and user experience. In its first hour of launch, Strings Brasil generated over R$ 20,000 in revenue and supported more than 4,000 simultaneous users. The platform gained national attention when one of Brazil's biggest singers, Gusttavo Lima, promoted it during a live stream, resulting in nearly 40,000 accesses.
