Sui announced on X platform that the confidential transfer function has been released in a public beta version on Sui Devnet. This feature can hide the transfer amount and account balance, while providing controllable visibility for compliance and auditing. Sui compares it to sealing the amount in an envelope, where the sender and receiver addresses are still visible but the amount is not. The issuer, exchange, or regulatory agency may access information based on authorization. The launch partners include Stablecoin, TRM Labs, and Merkle Science.
