Sui is testing confidential transactions on devnet, moving one of its privacy-focused upgrades from concept to the live development environment.
This feature is designed to keep transaction amounts and balances private while leaving sender and recipient addresses visible for auditing. This balance is important. Sui does not present this as complete anonymity. It aims for selective confidentiality which can be beneficial for financial institutions and applications.
Devnet testing began on June 8, 2026, according to Sui’s update.
The main caveat is that the secret transactions have not been published on the mainnet yet. This is still a feature in the testing phase, and final mainnet implementation may depend on performance, security review, developer feedback, and ecosystem readiness.
TL;DR
- Sui is testing confidential transactions on devnet.
- The feature hides amounts and balances while keeping addresses visible.
- It has not yet aired on the main network.
Why are confidential transactions important?
Public blockchains are transparent by default.
This transparency is beneficial for auditing, verification and trust processes. Anyone can examine balances, transactions, contracts and flows. But it also creates problems for certain types of users.
Businesses may not want competitors to see balances or payment amounts. Organizations may need privacy for business. Users may not want to see every transaction detail forever. Financial applications may require confidentiality without becoming completely opaque.
Secret transactions attempt to solve part of this problem.
By hiding amounts and balances while keeping addresses visible, Sui explores a middle ground. The network can support more privacy without making auditing of activity impossible.
This may be particularly relevant for enterprise use cases, payments, Premium assetsAnd applications where transaction-level confidentiality is important.
Privacy without complete anonymity
Distinguish between issues of confidentiality and anonymity.
A completely anonymous system can hide participants and values. This may appeal to some users, but it can create compliance and regulatory concerns. The selective confidentiality model keeps certain information visible while protecting sensitive financial details.
Sui’s approach seems closer to this second model.
Sender and recipient addresses remain visible, while amounts and balances can be protected. This design may make the feature more acceptable to companies or regulated entities that need audit trails but do not want to reveal all business details.
It also fits the broader market trend.
Cryptographic privacy has become more precise. The question is no longer simply whether transactions are public or private. It is the information that should be visible to whom and under what circumstances.
Networks that can provide flexible privacy may have an advantage as blockchain applications move beyond speculative trading.
Devnet testing is the appropriate stage for auditing
Privacy upgrades need careful testing.
Any encryption feature that changes what users can see or prove carries risks. Developers need to perform performance testing, wallet Compatibility, edge states, transaction costs, and security assumptions. Auditors need time to review implementation.
This is why devnet is important.
It gives developers a place to experiment before users adopt the feature with real value on the mainnet. Feedback from the testing phase can determine how the final implementation will work and whether changes are needed before wider deployment.
For Sui, the devnet phase also gives ecosystem builders a chance to think about applications.
Confidential transactions are the infrastructure. Their value depends on what developers build with them.
Sui Foundation’s offer is getting stronger
Sui has often positioned itself around high-performance applications, object-based architecture, and developer-friendly tools.
Privacy features can enhance this offer.
Enterprise users may be more willing to explore public chain applications if they can protect sensitive financial data. This doesn’t mean every organization will adopt Sui, but it does give the network another technical advantage to point to.
The same applies to Decentralized finance And payments.
If users can transfer assets without revealing the exact amounts to the entire market, it becomes possible to design new products. Treasury tools, payroll systems, special payments, and corporate settlement workflows can benefit from selective secrecy.
The challenge is adoption.
The devnet feature only makes sense if it reaches the mainnet safely and is then used by real applications.
For now, making Sui confidential transactions is a promising infrastructure step. It shows that the network takes privacy seriously while avoiding the claim that everything should be completely hidden.
This middle ground may become increasingly important as blockchain moves closer to mainstream financial use.
