Sui is preparing to bring private transactions to its mainnet, with stablecoin transfers slated as the first use case. Adeniyi Abiodun, co-founder and Chief Product Officer of Mysten Labs, said in a May 22 video posted on X that the feature is designed to reduce the amount of transaction history exposed when users send funds on-chain, while preserving auditability for regulated participants.
Sui Plans Private Stablecoin Transfers on Mainnet
Mysten Labs, the Web3 infrastructure company that developed the Sui layer-1 blockchain, is positioning privacy as a core requirement for mainstream payments. In the video, Abiodun framed the issue by comparing blockchain payments with traditional bank transfers, where a recipient does not gain visibility into a sender’s entire financial history simply because a payment was made.
“Very excited we announced that private transactions are coming on chain to SUI very soon. Why does privacy really matter? When you go to your bank today and you make a wire transfer to a friend or family, your bank does not continue by basically submitting your entire life’s history or your banking records to the recipient,” Abiodun said. He added that public blockchains create a different default by exposing historical activity to counterparties and observers.
The initial rollout is expected to focus on stablecoin transfers before expanding to other asset categories. Abiodun said the feature has already been tested on testnet and is planned for mainnet “very, very soon,” with Mysten aiming to extend the same privacy model over time to stocks, bonds and crypto assets. The stated goal is to allow users to send smaller or larger payments without revealing balances or prior transaction history to the broader internet.

Mysten Says Auditors Can Still Verify Payments
A central part of Mysten’s approach is that the privacy design is intended to remain compatible with regulatory and compliance needs. Abiodun argued that existing privacy systems often create problems for exchanges, custodians and fiat off-ramps because they do not provide the transparency or analytics required by regulated intermediaries.
“The most important thing about privacy is also it’s privacy that works from a regulatory point of view. Traditional privacy schemes that exist on the internet today do not allow you to own an off-ramp, do not allow you to make payments, and certainly do not allow you to go into exchanges because there are just rules around transparency and analytics that need to be met,” Abiodun said. He said Mysten has built cryptographic schemes intended to let issuers retain assurances about user behavior while limiting public visibility into transfers.
Under the model described by Abiodun, the sender and recipient would be able to see the amount sent or received, while the public would not receive visibility into the transaction details or the user’s broader account history. At the same time, he said auditors could still obtain a cryptographic assertion that a transaction occurred if needed. “Sender and recipient get privacy of their account balances. The public do not get any visibility into the transactions that’s being done, but of course an auditor, if needed upon request, will still be able to get some element of cryptographic assertion that transactions happened,” he said.
The planned Sui privacy feature reflects a broader effort among blockchain infrastructure teams to reconcile user confidentiality with the compliance expectations of issuers, custodians and exchanges. For Mysten Labs, the first test will be stablecoin payments on mainnet, where the project says users should be able to transact without exposing their full on-chain history while still leaving room for appropriate verification.
