The Sui mainnet has launched protocol-level zero-gas transfers as of May 20, enabling free transactions for seven assets, including USDC, without requiring users to hold SUI tokens. This development aims to enhance user accessibility and streamline transactions within the Sui ecosystem. In addition, Premium Exchange, developed by NAVI Protocol, is set to unveil its new system on May 26. These initiatives are designed to optimize the trading experience by reducing barriers at both the protocol and application levels, contributing to the growth and adoption of the Sui network.
