Sui Mainnet Restored, Confirms Both Downtimes Stemmed from Same Software Bug

Per an official announcement dated May 29th, the Sui mainnet has resumed normal operations, with transaction processing and full network activity back to standard function. Both today’s incident and the two network outages that occurred yesterday stem from an interaction bug between the "Address Balance" feature launched in version 1.72 and Sui’s gas fee logic. The fix deployed yesterday was a temporary measure to quickly restore network functionality, but carried a documented low-probability risk of triggering a subsequent outage. Today, a variant of this pre-existing issue activated, leading to another temporary mainnet shutdown. Validators have now successfully deployed a permanent fix; the official statement confirms all known issues tied to the original bug have been fully resolved, and the network has returned to normal operation. The Sui team has noted it will release a detailed incident postmortem report shortly, outlining the root cause of the failures and full remediation process.
