Sui (SUI) opened its confidential transfers feature to public testing on June 8, hiding token balances and transfer amounts onchain while leaving senders, receivers, and auditor access visible.
The design splits sharply from privacy coins like Monero (XMR). Sui conceals the numbers but preserves the controls that exchanges, analytics firms, and regulators depend on, aiming the feature at institutions rather than full anonymity.
A Privacy Model Built for Compliance
Confidential transfers let token issuers switch on a private mode where balances and transfer amounts stay encrypted on the Sui blockchain network. Sender and receiver addresses, the token type, and transaction timing all remain public.
“Confidential transfers is now available in public beta on Devnet, with a Testnet launch targeted later this year,” read an excerpt in the announcement.
The encryption uses Twisted ElGamal cryptography over Ristretto255, paired with zero-knowledge proofs.
Those proofs let the network confirm a transfer is valid without exposing the amount, which blocks overdrafts and unauthorized minting at the protocol level.
Mysten Labs published the open-source code on GitHub, where it remains unaudited and flagged as a work in progress. The release builds on the co-founder’s earlier preview of the system.

Where Sui Parts Ways with Monero
Monero hides all three layers of a transaction. Ring signatures obscure the sender, stealth addresses mask the receiver, and Ring Confidential Transactions conceal the amount. No outside party can decrypt that data.
That opacity has carried a cost. Dozens of exchanges have pulled Monero over compliance worries, a pattern that has fueled privacy coin delistings and intermittent privacy coin rotation across the market.
Sui takes the opposite route. Issuers can attach auditor keys so authorized parties decrypt balances when needed, and they keep freeze and seize powers.
Users can also prove a balance or a transfer amount without revealing their keys.
Why Issuers and Institutions Care
The approach targets payment firms, stablecoin issuers, and treasury teams that cannot broadcast their flows. Balances can reveal strategy, and transaction sizes can expose commercial relationships.
Bridge is exploring the system as a stablecoin and payments platform. TRM Labs and Merkle Science are testing how risk scoring, monitoring, and investigations function within the confidential model.
Notwithstanding, Sui has weathered a rough stretch, including three mainnet outages in late May.
Confidential transfers attracting the institutional users the chain wants will hinge on how partners and regulators respond to its model of controlled privacy.
Following the confidential transfers debut, the SUI token price is up by almost 5%, and was trading for $0.76 as of this writing, broadly aligning with broader altcoin market rip.
