Sui Launches USDsui Stablecoin With Treasury Yield Loop to Network

TLDR

• USDsui stablecoin launched on the Sui blockchain on Wednesday.
• Reserve assets include bonds and other liquid financial instruments.
• Yield from reserves will fund SUI token buybacks and DeFi liquidity.
• Bridge issued the stablecoin after Stripe acquired the firm in 2025.
• Mysten Labs founders previously worked on Meta’s Libra digital currency project.

Sui blockchain introduced its native stablecoin USDsui on Wednesday, linking token reserves to ecosystem funding. The project directs yield from reserve assets toward SUI token buybacks and DeFi liquidity programs. Mysten Labs co-founder Adeniyi Abiodun said the design returns financial value to the network.

USDsui Launch Ties Reserve Yield to the Sui Ecosystem

USDsui launched as Sui’s native dollar-pegged token backed by bonds and liquid assets. Bridge issues the token after Stripe acquired the stablecoin firm last year.

Reserve income will fund SUI token repurchases that remove supply from circulation. The foundation may also route the yield into DeFi pools and market-making.

Abiodun said traditional stablecoin issuers usually retain revenue generated by treasury reserves. He said USDsui instead cycles that income directly back toward Sui ecosystem activity.

“That yield can return from the foundation straight into the Sui ecosystem,” Abiodun said. He added that the structure connects real-world finance revenue with decentralized finance incentives.

The stablecoin sector already exceeds $300 billion, led by Tether and Circle. Those issuers keep the treasury income produced by reserves backing USDT and USDC tokens.

Abiodun said that model channels revenue outside blockchain ecosystems using the assets. He explained USDsui aims to close that loop through ecosystem-focused capital distribution.

Network Liquidity and Institutional Interest Support Early Supply

Sui developers say network liquidity may help the stablecoin gain early adoption. The chain has processed over one trillion dollars in stablecoin transactions.

Existing holdings of USDC and other tokens may convert into USDsui supply. The Sui Foundation already holds stablecoins that could shift into the new token.

Mysten Labs may also mint the stablecoin using reserves it currently manages. Abiodun said investors and hedge funds have shown interest in minting USDsui.

“Bootstrapping this is actually very easy,” Abiodun said while discussing early participation. He stated several partners already plan to mint the token after launch.

Mysten Labs created Sui after former Meta engineers left the Libra project. The earlier digital dollar effort was later rebranded as Diem before Meta abandoned development.

Abiodun co-founded Mysten Labs alongside George Danezis, Sam Blackshear, Evan Cheng, and Kostas Chalkias. The group previously worked together on Meta’s blockchain research and Libra engineering team.

Sui developers released the stablecoin as part of broader decentralized finance infrastructure plans. The launch follows earlier announcements about the project in late 2025.

Bridge developed issuance infrastructure for USDsui after Stripe acquired the company in 2025 last year globally. The stablecoin began operating on Wednesday as teams started integrating liquidity pools across the Sui network today.
