PANews reported on May 21 that Sui has announced the launch of a gas-free stablecoin transfer feature. Users and businesses can now conduct peer-to-peer stablecoin transfers without paying gas fees or holding SUI tokens, reducing transaction fees to zero. This feature, powered by Fireblocks, is being rolled out gradually on the Sui mainnet. The upgrade supports multiple stablecoins including USDsui, SuiUSDe, AUSD, FDUSD, USDB, USDC, and USDY. This feature is based on Sui's newly launched Address Balances system, which simplifies on-chain fund storage and transfer processes while maintaining high performance and scalability. Sui stated that this upgrade will further propel Sui into becoming a core stablecoin infrastructure for enterprise payments, fintech, and AI agent-automated payment scenarios.
