# Lens Protocol

**APIs profiled:** 6

Lens Protocol is an onchain social graph and a developer platform for building social applications where users own their profile, content, and relationships. Originally launched on Polygon PoS, Lens has since evolved into Lens Chain — an L2 zkEVM rollup purpose-built for social — with the Lens v3 contracts redesigned around primitives like Accounts, Apps, Feeds, Groups, Graphs, and Actions. Developers integrate Lens through the Lens API (a GraphQL gateway over the indexed chain state), the Lens TypeScript SDK and React SDK, the underlying smart contracts, and an authentication layer that issues short-lived auth tokens after a SIWE-style signature. Lens powers social clients (Hey, Orb, Tape, Buttrfly), creator tools, and composable mini-apps that share the same onchain social graph.
