Sui stablecoin USDsui officially launched: government bond yields will flow back into the ecosystem and support the SUI buyback mechanism
On March 5th, it was announced that the native stablecoin of the Sui blockchain, Sui Dollar (USDsui), officially launched on Wednesday. This stablecoin is issued by Bridge, and one of its core mechanisms is to channel the revenue generated from supporting reserve assets back into the Sui ecosystem, to promote DeFi liquidity and token economic development.
Adeniyi Abiodun, co-founder of Mysten Labs, stated that the reserve assets backing USDsui mainly include U.S. Treasuries and high-liquidity assets. The income generated from these assets is not fully retained by the issuer but can be used to buy back and burn SUI tokens in circulation or invested into decentralized finance protocols and automated market-making systems to enhance token exchange liquidity and incentivize ecosystem activity.
Currently, the global stablecoin market size has reached approximately $310 billion, dominated by mainstream USD stablecoins such as USDT and USDC. In traditional stablecoin models, much of the yield from U.S. Treasuries is typically captured by the issuing institutions and not directly fed back into the blockchain network itself. Abiodun pointed out that USDsui aims to change this model by redistributing real-world asset yields back into the blockchain ecosystem, making stablecoins an important tool for driving network growth.
USDsui is issued by the stablecoin company Bridge, which was acquired by payment technology giant Stripe in 2025. The Sui ecosystem first announced plans to launch a native stablecoin by the end of 2025, and now it has come to fruition, seen as a key step in the network’s infrastructure development for stablecoins and DeFi.
Abiodun mentioned that the Sui ecosystem currently holds a certain amount of USDC and other stable assets, which can be directly converted into USDsui. Additionally, market participants including institutional investors and some hedge funds have shown strong interest in minting USDsui, providing a solid initial liquidity base for the stablecoin.
The Sui blockchain was created by a team of former Meta engineers who previously worked on Meta’s early digital currency projects Libra/Diem. Core founding members of Mysten Labs also include technical leaders such as George Danezis, Sam Blackshear, Evan Cheng, and Kostas Kryptos Chalkias. The team believes that combining real-world financial yields with on-chain financial systems could create a more sustainable value cycle for the DeFi ecosystem.
As stablecoins gradually expand into global payments, on-chain finance, and real-world assets, the launch of USDsui is seen as an important step in strengthening Sui’s stablecoin infrastructure and promoting DeFi liquidity growth.
