EIP-8065는 영지식 증명을 활용하여 ERC-20 토큰을 프라이버시 보호 래퍼로 감싸는 Zero Knowledge Token Wrapper 표준을 제안하는 Draft ERC입니다. 사용자가 잔액과 거래를 비공개로 유지하면서 기존 DeFi 생태계와 호환성을 유지할 수 있게 합니다.
Privacy Motivation
Standard ERC-20 tokens are fully transparent — all balances and transfers are visible on-chain. For many use cases, this lack of privacy is a barrier to adoption, particularly in enterprise and regulated contexts. EIP-8065 proposes a standard wrapper that uses zero-knowledge proofs to shield token balances and transactions.
ZK Wrapper Mechanism
Users deposit tokens into the ZK wrapper contract, which issues shielded notes representing their token balance. Transfers within the shielded pool are executed using zero-knowledge proofs that prove validity without revealing sender, recipient, or amount. Withdrawals convert shielded notes back to standard ERC-20 tokens.
Standardization Benefits
Without a standard interface, ZK token wrappers are implemented differently by each project, creating fragmentation. EIP-8065 aims to define a common interface for wrapping, shielded transfer, and unwrapping operations. This would allow wallets and applications to support privacy tokens from any compliant wrapper without custom integration.
Draft Considerations
Key design questions include which ZK proving systems to support, how to handle compliance and regulatory requirements, and how to handle edge cases like failed proof submissions. The standard must be flexible enough to accommodate different ZK backends while providing a consistent user experience. Regulatory compliance hooks are under discussion.
