Sui network hits $1T stablecoin volume as confidential tx upgrade nears
Sui network has surpassed $1 trillion in cumulative stablecoin transaction volume since August 2025, according to DeFiLlama. The report also shows Sui’s TVL at about $643 million and stablecoin supply near $571 million.
At Consensus 2026, Mysten Labs co-founder Adeniyi Abiodun said Sui will introduce confidential transaction features before year-end. The key change is user-selectable privacy—participants can choose which transaction data stays private, rather than automatically hiding everything. Sui positions this as enabling “private and free payments at scale,” including a push toward zero-fee stablecoin transfers.
The announcement arrives as SUI trades around $1.27, up more than 37% in two weeks (from about $0.91 at the start of May). Price momentum has been supported by the launch of SUI futures on regulated exchanges and anticipation of the privacy upgrade.
The article also notes prior network disruptions: a consensus mismatch among validators in January 2026 caused hours of downtime, and a transaction-scheduler bug halted the network for about three hours in November 2024. Looking forward, Sui is trialing post-quantum cryptographic signatures on its testnet ahead of expected EU quantum-resistance rules by 2030, though no exact launch date for confidential transactions was provided.
Uncertainty remains on scope (whether privacy applies only to stablecoin transactions or to other token types), which could affect how traders price the upgrade.
Bullish
This is likely bullish for traders because it combines (1) measurable traction (Sui network stablecoin volume clearing $1T) with (2) a concrete catalysts narrative (confidential transaction rollout before year-end) and (3) market structure support (SUI futures on regulated venues). Historically, when a high-liquidity L1/L2 network pairs adoption metrics with an upcoming privacy/utility upgrade, the market often reprices risk premia quickly—first via derivatives flows, then via spot momentum.
In the short term, the upgrade headline and the already strong SUI move (+37% in two weeks) can attract momentum traders and trend-following strategies, increasing volatility around any confirmation headlines (testnet progress, partner integrations, regulatory clarity). However, the cited past downtime incidents and the lack of an exact launch date add headline risk; traders may fade rallies if timelines slip.
In the long term, user-selectable privacy could differentiate Sui if it proves technically resilient and if adoption extends beyond stablecoins. If privacy features gain traction without repeated network instability, it could improve sustained demand for the ecosystem and reinforce a higher base valuation for SUI. If the privacy scope is limited or launch execution disappoints, the market may revert to a neutral or corrective stance.
