The Group feature on Lens enables the creation of onchain community with customizable rules and governance. Each group is a smart contract that can be linked to applications, allowing for tight integration between user groups and the platforms they interact with. Groups can set join rules using the modular rule system—for instance, requiring members to own a certain token or NFT, or to pay a fee to join. This flexibility allows groups to tailor their membership criteria to their specific needs.

Members can participate in dedicated group feeds, fostering focused discussions and content sharing. Admins have control over membership, including the ability to ban or remove members, and can set up group-specific usernames and even associate an ERC20 token with the group. Metadata settings allow communities to define their purpose and guidelines clearly, enhancing transparency and cohesion among members.
