About This Project
Meflex Crypto Wallet is a user-friendly, mobile-first Web3 wallet built to make self-custody approachable for everyone. It abstracts key management and fee complexity behind a clean UI, while keeping power features one tap away. Users can manage multiple accounts, swap tokens, connect to DApps, and track activity in real time. The app is fully internationalized (i18n) so UI, dates, and numbers adapt to each user’s locale.
Key features
