Sui is expected to introduce private transactions this year, according to a May 11 post on X by Mysten Labs co-founder and chief product officer Adeniyi Abiodun. He said the feature is aimed at enabling scalable, free, privacy-preserving payments on Sui, a blockchain network developed by Mysten Labs. Private transactions generally refer to transfers designed to obscure some transaction details onchain, a feature often pursued to improve payment confidentiality while maintaining blockchain-based settlement.
