We are upgrading our Sui Mainnet infrastructure to v1.72.2.
This release introduces two major protocol enhancements:
Address Balances, which introduces a canonical per-address balance model for each token type alongside the existing Coin object model, and Gasless Stablecoin Transfers, which enables supported stablecoins (USDC, USDSUI, SUI_USDE, USDY, FDUSD, AUSD, USDB) to be sent peer-to-peer with no gas fees and no gas token required.
This release also bumps the rpc-index DB version to 4, which requires full re-indexing on startup.
During the maintenance window, customers may experience extended disruptions to RPC availability as nodes are rotated through the upgrade process and complete re-indexing.
RPC Changes:
GraphQL — added new TransactionEffects.version field for typed TransactionEffects version (v1, v2, etc).
gRPC — rpc-index DB version updated to 4; no API surface change, but indexes are rebuilt on upgrade.
Protocol — Address Balances and gasless stablecoin transfers are enabled on mainnet at protocol version 125, introducing new transaction construction patterns clients can take advantage of.
