- Sui adds confidential transfers on Devnet to hide amounts while keeping users visible.
- Asset issuers can enable private token transfers with auditability and compliance access.
- Bridge, TRM Labs, and Merkle Science are reviewing payment and monitoring use cases.
Sui has activated confidential transfers on Devnet in public beta today. The feature hides token balances and transfer amounts while keeping senders and receivers visible. The layer-1 blockchain said the design supports auditability for regulated payment and asset use cases.
The update targets a privacy gap on public blockchains. Standard on-chain transfers expose balances, payment sizes, and commercial links to anyone tracking a ledger. Sui said this visibility can limit adoption by asset issuers, enterprises, payment firms, and other financial users.
Sui Uses Controlled Visibility for Token Transfers
Asset issuers can now enable confidential mode for selected tokens. In that setting, public viewers cannot see account balances or transfer values. Participant identities remain visible, and the system keeps compliance controls available for authorized review when rules or investigations require access.
The model does not create fully anonymous transactions. Sui described it as a controlled-visibility framework for tokens that need privacy without removing oversight. Issuers can decide how and when sensitive information may be accessed, while keeping enforcement options tied to the token design.
Public and confidential transfers can run together on the network. That structure lets applications apply different disclosure levels based on the type of transaction. The protocol also separates roles at the base layer, with no automatic privileged access given to one platform or outside service.

Bridge, a stablecoin infrastructure provider and issuer, is among the early collaborators. The company is exploring how confidential transfers could support payments and enterprise activity. Sui also named TRM Labs and Merkle Science as firms assessing monitoring, risk scoring, and investigation tools.
Developers Get Access to Sui Devnet Privacy Tools
Those analytics firms are reviewing how compliance work can function without constant public disclosure of amounts. Their role points to the oversight focus behind the beta and the announced partner review. The structure aims to let investigators and service providers operate while limiting unnecessary exposure of financial data.
Sui plans to launch the feature on testnet later in 2026. Broader availability is expected after that step, according to the announcement. Developers can already access open-source tools and documentation linked to the Devnet beta, and the project has asked builders to submit feedback, especially in payments, stablecoins, and compliance-focused applications.
The first public details came on June 5 through posts on X. Sui co-founder Adeniyi Abiodun said the main challenge was not only hiding amounts but also preventing hidden supply manipulation. He said the team used range proofs on transfer amounts while keeping supply conservation inside the protocol.
The rollout comes as blockchains compete for stablecoin and institutional payment use. Public ledgers often offer transparency but limited privacy for business activity. Sui is positioning confidential transfers as a middle path between open settlement and controlled financial confidentiality, while adoption will depend on future developer, market, and issuer response.
