# Join Tribe

OpenSocial users can surf around and join different Tribes. A Join NFT (ERC-721) will be minted every time the user joins a Tribe, which will be recorded in the user’s social graph. Due to account abstraction (ERC-4337), the minting and gas fee can be paid by third parties on the user’s behalf.
