Sui co-founder Adeniyi Abiodun announced on June 5 that confidential transfers are coming to the Sui network, revealing the plans in a thread. The feature will use range proofs to hide transaction amounts, while supply conservation is enforced by the protocol itself — not by the privacy proof. That split is intentional.
A Design Built to Avoid the Zcash Orchard Bug
By separating privacy from supply integrity, Sui's designers aim to sidestep a vulnerability that plagued Zcash's Orchard protocol. In that case, combining both functions allowed unauthorized minting — a counterfeiting bug. Sui's approach keeps the privacy proof focused only on hiding amounts, while the network's core rules guarantee no coins are created out of thin air. The result, Abiodun said, is a system that's both more private and more robust against exploits.
More Than Just Private Transactions
Confidential transfers are only one piece of a broader push. Sui has already launched free tier payments and is working on native payment intents that would let AI agents transact autonomously on-chain. Walrus, Sui's decentralized storage network, is being positioned as the memory layer for those AI agents. Abiodun described that combination as a 'heads down' building strategy, noting that 'bear markets separate builders from those who only tweet.'
A Track Record of Outages and the Stakes for Delivery
Sui's past hasn't been smooth. The network suffered three mainnet outages caused by upgrade bugs, plus a separate network stall that sent the token price sliding. Delivering confidential transfers on schedule would send a clear signal: Sui's infrastructure-first approach can actually ship working products. The timeline for release hasn't been disclosed, but the announcement sets expectations that the feature is actively being built.
