selfxyz/self-sbt

SelfSBTV2 is a smart contract that implements Self's identity verification system using Soulbound Tokens (SBTs), designed for dApps that want to verify user identity while preserving privacy through a one-to-one relationship between each application and its own SBT contract. The contract uses zero-knowledge proofs and nullifier-based anti-replay protection to ensure each user can only have one active token per dApp, with configurable validity periods and owner-controlled burn capabilities for abuse prevention.
