Gasless transfers launch with an allowlisted stablecoin set
The feature applies to an allowlisted set of supported stablecoins, not to every token or transaction on Sui. Sui’s announcement listed USDsui, suiUSDe, AUSD, FDUSD, USDB, USDC and USDY as supported assets at launch. The official Sui documentation says eligible stablecoins are governed by protocol configuration through get_gasless_allowed_token_types, and that the allowlist can change across protocol versions.
The official documentation identifies the eligible asset list by issuer and package address: USDC by Circle, USDSUI by Bridge/Stripe, SUI_USDE by Ethena, USDY by Ondo, FDUSD by First Digital, AUSD by Agora and USDB by Bucket Protocol. That confirms an allowlist-based implementation rather than a blanket gasless model for all Sui assets.
The transaction scope is also limited. Sui’s documentation says gasless stablecoin transfers apply only when a transaction uses allowlisted balance or coin operations for an allowlisted stablecoin, with gasPayment empty and gasPrice = 0. Sending SUI, sending non-allowlisted assets, minting NFTs, swapping tokens or interacting with other applications still requires normal gas payment.
SIP-58, protocol mechanics and Fireblocks support
The technical foundation is linked to SIP-58, Sui Address Balances, created on December 5, 2025. SIP-58 describes address balances as a canonical balance for each (SuiAddress, Balance<T>) pair, reducing reliance on coin-object handling for fungible assets and simplifying balance tracking, indexing and transaction construction. The proposal preserves Sui’s object-centric model for non-fungible assets and other object-based use cases.
Sui’s release notes connect the rollout to protocol-version changes. PR #26417 added the mainnet stablecoin gasless allowlist in protocol version 123, while gasless remained disabled on mainnet at that stage. PR #26504 enabled address balances, gasless transactions, coin reservations and the accumulator/withdraw stack on mainnet at protocol version 125, with gasless initially gated behind an empty token allowlist until follow-up configuration.
Fireblocks’ role is integration support, not evidence of broad institutional adoption. Sui’s announcement says Fireblocks integrated the solution before rollout as part of Sui’s payments expansion, and quotes Ran Goldi, Fireblocks’ SVP Payments & Network, saying the feature reduces friction for enterprises building onchain payment flows and customer experiences. Fireblocks’ own X post also said gasless stablecoin transfers were live on Sui Mainnet and that Fireblocks had integrated ahead of rollout.
Sui’s claim that the feature is not a subsidy or temporary promotion comes from the official announcement, which presents gasless stablecoin transfers as a structural protocol change for single and batched peer-to-peer transfers of supported stablecoins. Broader claims about Sui becoming payment infrastructure, gaining institutional adoption or enabling AI-agent payment rails remain market positioning until supported by post-launch transaction data, customer disclosures or independent usage metrics.
