Memebook has completed a $1 million seed funding round backed by TOF. Ventures, marking fresh financing for a social media application built in the Solana ecosystem. The product is described as an Instagram-like app on Solana that allows users to register with a Solana wallet and post photos, videos and text updates. It also uses wallet-based identity authentication and includes verification features for Solana Mobile users and other Solana wallet users, highlighting how crypto-native social platforms are trying to tie online identity and user activity to onchain accounts.
