Scheduled

We are upgrading our Aptos mainnet nodes to v1.43.1. During the maintenance window, brief interruptions to RPC availability may occur. This release includes a gas version bump with increased transaction costs, critical bug fixes, and storage optimizations.

## RPC Changes

**Gas costs and storage fees — modified**
Gas costs and storage fees have been increased by a 10x multiplier. Applications with hardcoded gas estimates or assumptions about transaction pricing should review and update their configurations accordingly.
