Lens Protocol is a decentralized social graph protocol launched by the Aave team on Polygon in May 2022, designed to solve social media’s platform lock-in problem by making users’ social identities, content, and follower relationships ownable as NFTs rather than locked in centralized platform databases. On traditional social media (Twitter/X, Instagram, TikTok), if a platform bans you, changes its algorithm, or shuts down, you lose your entire social infrastructure — your followers, content archive, and engagement history. Lens Protocol inverts this: a user’s profile NFT is their social identity (stored on Polygon as an ERC-721), their publications (posts) are recorded on-chain, their follows create “Follow NFTs”, and any application can build on this shared open data layer. hay.xyz (formerly Lenster), Orb, Phaver, and dozens of other apps all display the same Lens social graph — if you switch from one Lens app to another, you bring all your followers and content. Lens is an experiment in composable social primitives on blockchain, exploring whether decentralized infrastructure can support sustainable social communities at scale without centralized data extraction.
Core Primitives
Profile NFT (ERC-721)
- Minted once per user; held in wallet
- Represents the user’s on-chain identity
- Used to post, follow, collect, and interact
- Transferable — can sell/transfer your social identity
Publication Types
- Post: Original content (text, image, video hash stored on IPFS)
- Comment: Reply attached to another publication
- Mirror: Equivalent to retweet — amplifies another publication
Follow NFT
- Minted when someone follows you
- Can be made transferable (tradeable followers) or non-transferable
- Follow modules allow custom logic: gated follows (must hold NFT), paid follows, etc.
Collect NFT
- Each publication can have a “collect module” — allows followers to mint the post as an NFT
- Enables creator monetization: charge to collect a specific post
- Collect NFTs are standard ERC-721s — tradeable on secondary markets
