# Profile

Each user creates a non-transferrable Profile Soulbound Token (ERC-721) on the OpenSocial protocol. Individual wallet addresses own Profile SBTs. The Probile SBT records the number of on-chain social actions. 

Users own their social graph and on-chain content and reactions through ownership of the Profile SBT.
