# Privacy.cash

Privacy.cash is a ZK-proof privacy pool protocol on Solana that enables cryptographically private deposits and withdrawals. The protocol uses commitment-based deposits where ownership is provably hidden, creating anonymity sets that strengthen with usage. Privacy.cash serves as infrastructure for privacy-preserving DeFi applications.
