The release aims to help projects meet regulatory requirements such as MiCA, BSA, AML/KYC, and GDPR, which are difficult to satisfy when user transaction data is published on a public blockchain. Privacy Boost combines zero-knowledge proofs with trusted execution environments, where ZK proofs ensure privacy and cryptographic integrity, while TEEs improve performance and simplify integration. Built on a UTXO-based model, the solution can generate proofs in under 500 milliseconds and includes a forced withdrawal feature. Privacy Boost is now live on OP Mainnet.Sponsored by EarnUSD is a stablecoin vault by Lido for earning transparent, onchain USD-denominated rewards.
