Sui’s protocol-level gasless stablecoin transfers are now part of its production payment stack, allowing eligible peer-to-peer transfers to execute without users holding SUI or paying a network fee. According to the Sui Foundation’s official launch announcement, the feature went live on May 20 and initially supported USDsui, SuiUSDe, AUSD, FDUSD, USDB, USDC and USDY. For qualifying transfers, the network sets the gas cost to $0 rather than shifting the fee to a sponsor.
That distinction separates the mechanism from conventional sponsored transactions. Sui’s documentation says an eligible transaction must use only allowlisted coin or balance operations, primarily balance::send_funds, while setting an empty gas payment and a gas price of zero. It also cannot write objects. The zero-fee treatment therefore applies to a deliberately constrained class of stablecoin transfers, not to arbitrary smart-contract execution across Sui.
Address Balances Remove the Separate Gas Requirement
The feature is built around Address Balances, an account-style system that lets users maintain fungible balances without manually selecting individual coin objects. For ordinary transactions, Address Balances can also hold SUI used for gas, but qualifying stablecoin transfers follow a different execution path in which nobody pays a network fee. Users can move an allowlisted stablecoin directly without first acquiring a separate SUI balance purely to fund the transaction.
That architecture targets a longstanding operational issue for payment applications. Businesses managing thousands of customer wallets normally need to provision native gas tokens, monitor balances and replenish them as transactions occur. Similar efforts to simplify stablecoin payments were already visible when RedotPay added native USDC and SUI to its payment rails. Protocol-level zero-gas transfers remove one layer of treasury management specifically for supported payment flows, while leaving normal gas economics intact elsewhere on the network.
There is now evidence of the feature being used beyond the protocol launch itself. In September, Daya integrated Sui as settlement infrastructure across its business, professional and API products in Nigeria, using gasless stablecoin transfers for cross-border payments and treasury rebalancing. That deployment provides a concrete application of the capability, although it does not establish network-wide adoption or disclose the volume specifically processed through gasless transfers.
The same payment primitives are also being positioned for machine-driven transactions. Sui has linked gasless transfers with its broader work on agentic commerce, where software agents may need to execute large numbers of small payments without maintaining separate gas inventories. ChainReport previously examined that wider infrastructure in the context of Sui’s payment and authorization stack for AI agents. The infrastructure exists today, but autonomous-agent usage should still be measured separately from technical availability.
Sui Expands Its Broader Financial Stack
The gasless feature sits alongside a wider set of financial infrastructure rather than representing a standalone institutional product. Sui has also connected with regulated-market providers, including a tZERO integration for digital securities infrastructure, while its broader stablecoin ecosystem continues to expand. Payments, custody, tokenization and securities infrastructure are distinct layers, even when they share the same underlying blockchain.
On October 1, Sui also announced its participation in the Open Tokenized Asset Standard, or OTAS, alongside OpenAssets under Linux Foundation Decentralized Trust. OTAS is a chain-agnostic framework intended to standardize identity, compliance information, ownership history and settlement metadata for tokenized assets. OTAS expands Sui’s institutional tokenization toolkit, but it is separate from the protocol mechanics that make stablecoin transfers gasless.
Sui’s broader development environment is commonly described by the Foundation as the Sui Stack, combining execution with components for storage, access control and off-chain computation. The gasless payment feature should therefore be understood as one production capability inside a larger architecture, not as evidence that every part of Sui’s institutional or tokenization strategy has reached equivalent adoption. The strongest current evidence is narrower: selected stablecoins can move peer-to-peer on mainnet at zero network cost, and at least one commercial payments provider is already using that functionality in live settlement workflows.
