Overview
- Sui rolled out protocol-level gasless stablecoin transfers on Mainnet on May 20, setting fees to $0 for eligible peer-to-peer stablecoin sends.
- The network processes zero-fee transactions by letting eligible Move balance operations set gas price to zero so the protocol absorbs the cost while paid transactions get priority during congestion.
- Seven stablecoins are allowlisted at launch: USDC, USDsui, suiUSDe, AUSD, FDUSD, USDB and USDY.
- Fireblocks integrated support at launch to speed distribution to custodians, exchanges and enterprise clients, simplifying treasury and payment flows for businesses.
- Sui’s object-centric design and the new Address Balances system enable per-asset fee rules without third-party relayers, and the change follows the network’s report of over $1 trillion in stablecoin transfers since August 2025 while raising questions about fee sustainability and SUI demand.
