Sui launched protocol-level gas-free stablecoin transfers on mainnet, allowing users and businesses to send supported stablecoins peer-to-peer without paying gas fees or holding SUI for transaction costs. The network said the feature is intended to reduce payment friction and simplify onboarding for blockchain-based payments. New coverage says gasless transfers could support broader blockchain adoption by lowering user friction, but also notes that sustainability and network economics remain key concerns. Sui has also said processing volume after August 2025 is expected to exceed $1 trillion, and that privacy payments are planned for 2026.
