Sui Dollar ($USDsui), the fiat-backed native stablecoin of the Sui blockchain issued by Stripe-owned Bridge, has begun trading on crypto exchange Bullish in eligible jurisdictions in the weeks after its March 4, 2026 launch.

The listing puts the token on a centralized order book ahead of most stablecoins of comparable age. USDsui trades under the ticker $USDsui and has held its $1.00 peg since launch.

Who issues USDsui?

Bridge, a stablecoin issuance company owned by payments company Stripe, issues USDsui on a 1:1 basis through its Open Issuance platform. Each token is backed by dollar reserves weighted toward short-dated US Treasuries, supplemented by repurchase agreements, money-market funds and cash.

The Stripe affiliation distinguishes USDsui from stablecoins managed by crypto-native issuers. Bridge has positioned Open Issuance as a turnkey issuance stack that lets corporate or chain-native partners deploy dollar tokens without standing up their own reserve and compliance operations.

What changes about the yield model?

Most fiat-backed stablecoins operate on a single revenue stream: the issuer retains interest earned on reserve assets. USDsui diverges from that arrangement by directing reserve yield toward two uses: open-market buybacks of the Sui network's native SUI token and liquidity incentives for DeFi pools on Sui.

The structure ties the stablecoin's economics to activity on one specific chain. It also creates recurring buyback demand for SUI as long as reserve interest accrues at prevailing rates.

How large is USDsui today?

Circulating supply sits between roughly 78.5 million and 78.85 million tokens, placing market capitalization near $78–79 million. USDC, issued by Circle, remains the dominant stablecoin on Sui by volume; USDsui ranks second in several network-activity snapshots.

Stablecoin transfer volume on Sui crossed $100 billion in early 2026, alongside growing institutional demand for stablecoin settlement, per the network's reporting.

Where does USDsui already operate on-chain?

Before the Bullish listing, the token had been deployed across several Sui-based DeFi venues. Integrations span:

• Cetus, a concentrated-liquidity automated market maker
• Bluefin, a derivatives exchange
• Turbos Finance, another AMM

These integrations mean USDsui can already be swapped, lent and posted as collateral on Sui without routing through Bullish.

What does the Bullish listing change?

The exchange venue gives traders a fiat-adjacent entry point into USDsui without bridging from another chain or maintaining a Sui-native wallet. That lowers the operational hurdle for participants that run books on centralized venues and want exposure to a Sui-denominated dollar.

Bullish operates as a spot and derivatives venue built around a central limit order book. Availability for USDsui will depend on each user's jurisdiction under the listing's eligibility rules.

What risks frame the next six to twelve months?

Three structural concerns frame the outlook:

• USDsui is weeks old and its float is a fraction of USDC's
• Its success depends on continued activity within a single blockchain
• The buyback mechanism exposes SUI holders to interest-rate movements that compress or expand reserve income

The Bullish listing is the first major centralized venue for the token. Further geographic expansion, additional DeFi integrations and periodic disclosure on reserve composition will determine whether USDsui converts its current second-place standing on Sui into durable market share.
