Sui just got its own stablecoin. USDsui launched on Sui mainnet on March 4, 2026, issued by Bridge, a Stripe subsidiary, using its Open Issuance platform. The Sui Foundation and Bridge worked together on the mainnet deployment. It’s designed to be a fully interoperable stablecoin built specifically for the Sui ecosystem.
The backing model is straightforward. USDsui is backed by bonds and liquid assets managed by Galaxy Digital. At launch, $10M was deployed into a yield-generating vault. The reserve model is transparent and deliberately structured to sidestep DeFi exploit risks. It’s also built to comply with the GENIUS Act upon effectiveness.
Here’s where it gets interesting. Instead of keeping the yield from backing assets, the project reinvests it back into the Sui ecosystem. That means SUI token buybacks and burns, liquidity incentives for DeFi protocols and AMMs, and deeper on-chain activity. Unlike USDT and USDC, which pocket that treasury yield, USDsui redirects it. The compounding effect between real-world income and on-chain activity is kind of the whole point.
Sui’s network performance actually makes this viable. The chain processed over $111B in stablecoin transfers in January 2026 alone. Between August and September 2025, it handled $412B in stablecoin volume. Sub-second finality, parallel execution, low fees. The infrastructure isn’t the problem here.
USDsui launched with live integrations across major Sui DeFi protocols for lending, trading, and liquidity. It connects with DeepBook’s margin system, yield vaults, and synthetic stablecoins like suiUSDe. Incentive programs are already running to pull users in and build liquidity depth. This programmable money capability enables automated transaction execution directly within Sui’s smart contract environment.
Institutional interest is real too. Bitwise, Franklin Templeton, Grayscale, and VanEck are already involved in Sui. U.S.-listed Sui staking ETFs started trading in February 2026. Hedge funds and investors are eyeing USDsui minting. TenX Protocols is planning staking after a $24M raise.
On the payments side, USDsui targets digital payments, cross-border transfers, and remittances. It settles quickly with low, predictable fees, making it practical for high-volume payment use cases at scale. The team behind it includes co-founders with deep roots in Meta’s Libra project, bringing prior experience building large-scale stablecoin infrastructure before it was shelved. It’s positioned as the foundational stablecoin for Sui’s entire onchain economy. Whether it delivers is another story.
