Sui Launches "Fee-Free Stablecoin Transfer" Feature

May 21. Official sources confirm Sui has launched its "Gas-Free Stablecoin Transfer" feature. Users and businesses can now send stablecoins peer-to-peer on the network with zero gas fees, no requirement to hold extra SUI token balances—meaning stablecoin transfers on the Sui network are officially $0. The feature is backed by Fireblocks and is rolling out gradually on the Sui mainnet. This upgrade supports a range of stablecoins including USDsui, SuiUSDe, AUSD, FDUSD, USDB, USDC, and USDY. Adeniyi Abiodun, Sui’s co-founder and Mysten Labs CPO, noted that stablecoins are emerging as critical global financial infrastructure, but users still face added complexity from having to manage gas tokens separately. The Gas-Free Transfer feature eliminates that barrier, making on-chain payments simpler, more predictable, and easier to adopt. Built on Address Balances—Sui’s new synchronized account balance system—the feature streamlines on-chain fund storage and transfer processes while maintaining the network’s high performance and scalability. Since August 2025, total stablecoin transfer volume on Sui has topped $1 trillion. Officials say this upgrade will further cement Sui’s position as a core stablecoin infrastructure for enterprise payments, fintech, and AI Agent automated payment use cases.
