Social Data Proofs
Frequently Asked Questions
Get clear answers on how we deliver verifiable social data infrastructure for StarkNet and zkSync.
Social Data Proofs are verifiable, on-chain attestations derived from social platforms (like Twitter, Discord, GitHub). We build the infrastructure to generate and verify these proofs, enabling you to create applications like token-gated communities based on follower count, sybil-resistant airdrops using engagement history, or reputation-based DeFi lending. Our service delivers the custom smart contracts and backend oracles to make this possible on StarkNet and zkSync.
