Sui has crossed $1 trillion in cumulative stablecoin transfer volume. DeFiLlama data cited in the report shows the blockchain has moved past that mark since August 2025, with $643 million in total value locked across its DeFi protocols and nearly $571 million in stablecoin supply.
Mysten Labs ties Sui’s next phase to free stablecoin payments
At Consensus 2026, Mysten Labs co-founder Adeniyi Abiodun said Sui wants to become “the sole platform enabling private and free payments at scale for the entire internet.” He described the network’s direction as a new financial infrastructure built around zero-fee stablecoin transfers.
Abiodun also pointed to the cost of cross-border money movement. His example was simple: sending $100 to Nigeria can result in a $35 commission. That gap, in his view, leaves room for blockchain-based payment rails to compete on settlement costs.
Confidential transfers are being designed as an optional setting
Sui’s privacy model is not being framed as blanket obscurity for all network activity. According to sources close to the company, the system under development would let users choose which transactions stay confidential, instead of hiding every transfer by default. That would place selective privacy at the center of the product design.
The timing matches broader market interest in privacy-focused crypto projects. The article notes that Zcash has risen more than 78% over the past month, as concern around quantum threats to public blockchains has grown and the supply of shielded coins has expanded. It also says Digital Asset Holdings, the developer behind Canton Network, is seeking to raise $300 million at a $2 billion valuation in a round led by a16z Crypto.
Growth metrics arrive alongside a record of network interruptions
Technical questions have not disappeared as Sui prepares its privacy upgrade. In January 2026, a consensus mismatch among validators caused several hours of downtime. Earlier, in November 2024, a software bug in the transaction scheduler stopped the network for three hours.
Even with those incidents, the SUI token has climbed sharply in recent weeks. Data from CryptoAppsy places SUI at around $1.27, up more than 37% over two weeks after starting May at $0.91. The report links that move to the launch of SUI futures on regulated exchanges and expectations tied to the coming privacy update.
Post-quantum signatures are on testnet, but no launch date is set
Abiodun said Sui’s growth has been helped by advanced on-chain market making and atomic multi-transaction capabilities, which he described as unique to the network. He also said post-quantum cryptographic signatures are now being tested on Sui’s testnet as the ecosystem gets ready for planned European Union quantum-resistance rules expected by 2030.
There is still no exact launch date for confidential transactions. The report also says it remains unclear whether privacy support will cover all token types or stay limited to stablecoin transfers.
