Base App, developed by Coinbase, has officially launched globally on December 18, following the conclusion of its beta phase. Now accessible in over 140 countries, the app integrates social, transactional, and payment functionalities into a single platform. Users can monetize their posts using the Farcaster and Zora protocols, and the app features mini apps for DeFi, prediction markets, and games. The onboarding process is streamlined, eliminating the need for mnemonic phrases, and includes a privacy-focused chat feature. Despite its innovative offerings, Base App faces challenges such as low user engagement and content quality issues.
