Sui Network Prepares Major Privacy Upgrade

Confidential Transfers Coming to Sui

Mysten Labs co-founder Adeniyi Abiodun has confirmed that Sui Network will introduce a Confidential Transfers feature to its Layer-1 blockchain. The upgrade is designed to shield transaction amounts from public view while ensuring that no hidden token supply can be secretly created, addressing one of the core risks associated with privacy-enabled assets.

Abiodun has framed privacy as a prerequisite for scaling on-chain payments to mainstream users, arguing that "it's impossible to get mass global consumer adoption for anything payments related without privacy." The feature is expected to launch in 2026 alongside zero-fee stablecoin transfers.

Protocol-Level Design Sets Sui Apart

A key distinction in Sui's approach is where the privacy sits. Rather than relying on optional add-ons, mixers, or separate privacy layers, the Confidential Transfers feature will be embedded directly into the protocol. Abiodun has described the vision as making Sui a default network for moving money, with private payments available across wallets, exchanges, and on- and off-ramp providers without users needing to opt in.

Supply conservation will be enforced at the protocol level, meaning the cryptographic design prevents any party from secretly inflating token balances under the cover of confidentiality. This directly addresses a longstanding concern with privacy-enabled blockchains, where hidden supply could theoretically be created without detection.

A Mysten Labs research paper laid out a formal framework for privacy on account-based blockchains like Sui, exploring techniques such as homomorphic encryption and zero-knowledge proofs to implement confidential balances without fully adopting the design of legacy privacy coins.

The announcement comes as $SUI has seen renewed institutional interest. CME Group launched regulated SUI futures on 29 May 2026, and the network has processed more than $1 trillion in stablecoin volume since August 2025, according to remarks made by Abiodun at Consensus 2026.
