Description

Privy-Lips is a privacy-preserving liquidity protocol on Mantle Network that addresses DeFi privacy and compliance. It uses zero-knowledge proofs and cryptographic commitments to hide deposit amounts, enable unlinkable withdrawals via nullifiers, and support selective disclosure for tax reporting without revealing exact amounts. The protocol includes a three-tier ZK-KYC system (Anonymous, Pseudonymous, Institutional) for compliance without exposing identity. By combining ZK proofs, Pedersen commitments, and selective disclosure, Privy-Lips enables private liquidity provision while meeting regulatory requirements protecting users from on-chain surveillance and targeted attacks while maintaining full compliance capabilities.
