Sui Stablecoin Goes Live, Treasury Yield Returns to Network

What to Know

USDsui, Sui's native stablecoin issued by Bridge, officially launched on Wednesday with a unique yield-sharing model
Revenue from U.S. Treasury bonds and liquid assets backing the token will be funneled back into the Sui ecosystem
The stablecoin market has swelled to a $310 billion market cap led by Tether and Circle, which keep all backing yield for themselves
Sui's network has already processed over $1 trillion in stablecoin volume, easing the bootstrapping challenge for USDsui

Sui's native stablecoin, dubbed the Sui Dollar or USDsui, went live on Wednesday with a distinctive twist: income generated by the Treasury bonds and liquid assets underpinning the token will flow back into the blockchain ecosystem rather than be retained by the issuer. The launch positions USDsui as a direct challenge to dominant stablecoins like USDT and USDC, whose operators pocket all reserve yield.

How Does USDsui Return Treasury Yield to the Network?

USDsui channels yield from its reserve assets into two main paths: repurchasing and removing Sui tokens from circulation, and deploying capital into decentralized finance protocols and automated market-making pools to incentivize swaps. Adeniyi Abiodun, co-founder at Mysten Labs, outlined the approach on Wednesday.

"I think we are starting to see a dislocation of the business model of stablecoin issuers, whereby the yield is largely kept to external agencies that don't really pour value back to the ecosystem," Abiodun said. He added that yield "effectively can get funneled back from the foundation straight to the Sui ecosystem."

We are all about closing that loop. So it's real yield from real world finance that is going back into DeFi that creates a flywheel.

Stablecoin Industry Backdrop and the Bridge Connection

The stablecoin sector has ballooned to a $310 billion market capitalization, dominated by Tether and Circle Internet (CRCL). Both firms retain all revenue from the massive pools of U.S. Treasury bonds backing their dollar-pegged tokens. USDsui is issued by Bridge, the stablecoin infrastructure firm that payments giant Stripe acquired last year. Plans for the coin were first disclosed toward the end of 2025.

The Sui blockchain was built by a team of former Meta engineers who previously worked on the social media company's abandoned Libra and Diem digital dollar project. Abiodun's co-founders at Mysten Labs include George Danezis (chief scientist), Sam Blackshear (CTO), Evan Cheng (CEO), and Kostas Kryptos Chalkias (chief cryptographer).

Bootstrapping USDsui With Existing Stablecoin Volume

Launching a new stablecoin becomes far simpler when the underlying network has already facilitated over $1 trillion in stablecoin transfers, according to Abiodun. The Sui Foundation currently holds USDC and other stablecoins that can be transitioned directly into Sui Dollar reserves, and Mysten Labs plans to do the same.

"We actually have a lot of investors and hedge funds who are interested in minting Sui USD. So bootstrapping this is actually very easy," Abiodun told reporters. The Bridge stablecoin infrastructure, now backed by Stripe's global payments reach, provides the issuance rails that could accelerate adoption across institutional and retail participants.

What This Means Going Forward

The arrival of USDsui signals a shift in how stablecoin economics may evolve. By returning Treasury yield to its native ecosystem through token buybacks and DeFi incentives, Sui is betting that shared revenue will attract more liquidity than the traditional model where issuers capture all reserve income. Whether this flywheel gains enough momentum to challenge Tether and Circle will depend on adoption speed and DeFi integration depth across the Sui network.
