PrivacyUSD is a decentralized privacy protocol developed on the Solana blockchain, engineered to provide robust confidentiality for stablecoin transactions. The project’s primary function is to enable users to transact with leading stablecoins, including USDC, USDT, and DAI, without exposing sensitive financial data on the public ledger. It achieves this through a proprietary 7-layer privacy stack that combines multiple cryptographic techniques, such as zero-knowledge proofs, multi-split fragmentation, and batch processing with delays, to deliver a high degree of anonymity and a claimed 0.0001% traceability probability.
