Sui is preparing to introduce native private transactions for stablecoins on its mainnet, a move aimed at improving user confidentiality and attracting more institutional activity to the blockchain network.
Key Takeaways
- Sui plans to make stablecoin transactions private by default on its mainnet.
- The privacy feature will be built directly into the protocol instead of relying on third party tools.
- SUI token surged more than 20% following the announcement.
- Mysten Labs says the upgrade could help institutions issue tokenized assets on chain with controlled visibility.
What Happened?
Sui Network announced that it is preparing to launch native private transactions focused on stablecoin transfers. The feature will be implemented directly at the protocol level and is expected to become a default setting for users on the network.
The update was revealed by Mysten Labs co-founder Adeniyi Abiodun, who said the new system is designed to give users greater privacy while still allowing regulators and token issuers to maintain appropriate oversight. The announcement triggered a strong market reaction, with the SUI token rising more than 20% shortly after the news surfaced.

Sui Pushes Privacy Into the Mainstream
Privacy has long been one of the biggest debates in the blockchain industry. Most public blockchains allow anyone to view wallet balances and transaction histories, creating transparency but also exposing sensitive financial activity.
Sui is now attempting to change that model by introducing confidential stablecoin transactions directly into its network architecture.
According to Abiodun, traditional financial systems naturally protect transactional data because banks and payment processors do not publicly expose user activity. Blockchain networks, however, were built around public verification, making privacy much harder to achieve without specialized tools.
Sui’s upcoming upgrade aims to solve that issue by ensuring that only the sender and receiver can see transaction details by default. The company said outside observers will not be able to access payment histories or balances linked to stablecoin transfers.
Importantly, Mysten Labs emphasized that the system will still support regulatory visibility where required. The company said issuers and regulators could receive controlled access to relevant transaction information, a feature designed to make the network more attractive for institutions and regulated financial products.
Abiodun previously explained the importance of this capability in comments made earlier this year.
He stated:
Stablecoins Become the First Focus
The first rollout of private transactions will center around stablecoins, which have become one of the most widely used products in crypto for payments and transfers.
The privacy upgrade comes shortly after Sui introduced gasless stablecoin transactions on the network. That feature allows users to send stablecoins without needing to hold SUI tokens to pay transaction fees, removing a major friction point for mainstream adoption.
By combining gasless transfers with default privacy, Sui is positioning itself as a payment focused blockchain that could compete more aggressively for enterprise and institutional use cases.
The company also revealed that the privacy framework is already being tested and could later expand to additional asset classes including stocks, bonds, and crypto assets.
Sui Seeks Institutional Edge
Sui’s approach stands out because most major Layer 1 blockchain networks, including Ethereum, Solana, and Avalanche, do not offer native privacy at the protocol level.
Privacy focused cryptocurrencies like Monero and Zcash have historically handled confidential transactions, but those networks have faced regulatory scrutiny and exchange delistings over the years.
Sui appears to be taking a different route by building a privacy system that still includes compliance controls and issuer visibility. Analysts believe this approach could help the network appeal to institutions looking to tokenize traditional financial products without exposing sensitive transaction data publicly.
The network, developed by Mysten Labs, officially launched its mainnet in May 2023. Built using the Move programming language, Sui focuses on scalability and high throughput transaction processing.
According to project data referenced in recent reports, Sui had already processed more than $1 trillion in stablecoin transaction volume as of August 2025.
CoinLaw’s Takeaway
In my experience, privacy has always been one of the missing pieces preventing blockchain payments from feeling practical for institutions and mainstream users. Most companies simply do not want their transaction history exposed to the public forever.
I found Sui’s approach interesting because it tries to balance privacy with compliance instead of treating them as opposites. If the network can actually deliver smooth private payments while keeping regulators comfortable, this could become a major competitive advantage in the Layer 1 race.
