1. Overview Privacy-preserving transfer system on Solana using zero-knowledge proofs, enabling anonymous SOL and SPL token transfers. The client’s goal was to prevent transaction traceability—ensuring that senders, receivers, and transfer amounts cannot be linked on-chain. 2. Challenges & Solution To achieve strong privacy on Solana, I designed a shielded pool architecture where users deposit assets and later withdraw to any address without revealing their private info. Zero-knowledge proofs are used to verify ownership and balances without exposing sensitive data, while maintaining security and efficiency. 3. Result The final solution is a fully audited, production-ready private transfer protocol on Solana that provides secure, unlink transactions while preserving Solana’s performance and low fees.
