Decentralized Identity for Verified Fan Access
Frequently Asked Questions
Get clear answers on how we build secure, scalable identity solutions for exclusive fan experiences.
We build a custom, on-chain identity layer that links real-world verification (like KYC) to a non-transferable Soulbound Token (SBT) or Verifiable Credential. This token acts as a persistent, privacy-preserving pass. Your platform's smart contracts then gate access to tickets, NFTs, or content based on token ownership. We handle the full stack: integration with verification providers, smart contract development for minting and gating, and a user-friendly wallet interface for claim and proof.
