Zengo is a self-custodial crypto wallet that differentiates itself through MPC technology, removing the need for seed phrases. It targets users who prioritize security and ease of use, offering a freemium model with advanced features like Web3 firewalls and inheritance planning. Despite a strong market position and high ratings, the app is currently suffering from a significant trust deficit. Users are reporting critical issues with fund withdrawals and unresponsive support, leading to a declining sentiment trend that threatens the app's long-term viability.
