SocialFi (Social Finance) is a category that combines social media with decentralized finance, allowing users to monetize their social interactions, content, and influence through blockchain and token-based incentives. SocialFi platforms enable features like tokenized social profiles, pay-to-access content, tipping in cryptocurrency, and on-chain reputation systems. The concept aims to shift value from centralized platforms (which profit from user data) back to the content creators and community members who generate it.
