ZkSync’s airdrop, launched in June 2024, didn’t mandate explicit KYC requirements for token claims, relying instead on activity-based eligibility and Sybil detection. This preserved user privacy by avoiding personal data collection, aligning with crypto’s decentralized ethos. However, it raised compliance concerns, as regulators increasingly demand KYC to curb fraud and money laundering. The absence of KYC enabled broader participation—695,232 wallets claimed $630 million in ZK tokens—but risked exploitation by airdrop farmers, with one user creating 21,877 wallets. Balancing privacy and compliance, ZkSync prioritized accessibility over strict regulatory adherence, potentially inviting future scrutiny.
