The Sui blockchain launched its native stablecoin, USDsui, on Wednesday, March 4, 2026, introducing a novel economic model where yield generated from the token's reserve assets is funneled back into the Sui ecosystem. The stablecoin is issued by Bridge, a stablecoin firm acquired by payments giant Stripe in 2025.
USDsui is backed by bonds and other liquid financial instruments. Unlike major stablecoin issuers like Tether (USDT) and Circle (USDC), which retain all yield from their U.S. Treasury-backed reserves, the income from USDsui's reserves will be directed toward repurchasing and burning SUI tokens from circulation or deployed into decentralized finance (DeFi) protocols for liquidity provisioning and incentivizing swaps.
Adeniyi Abiodun, co-founder of Mysten Labs—the original contributor to Sui—explained the rationale: "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. That yield effectively can get funneled back from the foundation straight to the Sui ecosystem." He emphasized the goal is to "close that loop" and create a "flywheel" where real-world finance yield powers DeFi activity on Sui.
The project benefits from significant existing network liquidity. Abiodun noted that the Sui network has processed over $1 trillion in stablecoin transactions. Both the Sui Foundation and Mysten Labs hold substantial amounts of stablecoins like USDC, which can be transitioned to USDsui. Furthermore, Abiodun stated that investors and hedge funds have expressed interest in minting the new stablecoin, making the bootstrapping process "actually very easy."
The development team behind Sui and Mysten Labs consists of former Meta engineers who worked on the abandoned Libra/Diem digital dollar project. The plans for USDsui were first announced in late 2025.
