Hera's Ledger is a privacy-preserving payment infrastructure designed to empower vulnerable groups, particularly women facing economic abuse, by enabling unlinkable transactions while maintaining compliance. It combines EIP-5564 (Dual-Key Stealth Addresses) for unlinkable receivership with ZK-SNARKs for privacy-preserving identity verification, allowing users to receive funds without revealing their wallet address while proving authorized status without disclosing identity. This project targets vulnerable populations needing financial autonomy and privacy, especially those in situations where transaction histories could be used for surveillance or control. The technical stack includes Node.js for core logic, Circom & SnarkJS for zero-knowledge proofs, and is actively developing on-chain integration and user-friendly interfaces to make privacy-preserving financial tools accessible to non-technical users.
