ConfidentialToken Association

OpenZeppelin co-founded the Confidential Token Association with Zama and Inco to establish industry-wide standards for confidential smart contracts. We're developing the Confidential Token Standard—a framework that brings encryption-based privacy to ERC-20 and beyond while maintaining composability and regulatory compliance. Why it matters: confidential tokens enable mainstream adoption of blockchain technology across payments, DeFi, and real-world assets by protecting sensitive financial data without sacrificing transparency or auditability.

Who's building with us: Stellar, Fhenix, Predicate, and other leading blockchain protocols are collaborating to make privacy the default standard for onchain applications, not an afterthought. Join developers, protocols, and institutions defining how privacy works onchain.
