Sui Network suffered three separate mainnet halts in less than 48 hours after a bug in its v1.72 software upgrade caused validators to stall repeatedly, knocking the Layer 1 blockchain offline and triggering over $2 million in long position liquidations.
The outages, which began late last week, forced the Sui development team to deploy emergency patches while validators coordinated a network restart each time the chain stopped producing blocks.
What Happened
The first halt occurred after validators upgraded to v1.72, which contained a gas logic bug. When certain transaction patterns hit the network, the gas metering system entered an inconsistent state, causing validators to disagree on the state of the blockchain. Without consensus, block production stopped entirely.
The Sui team deployed a fix and validators restarted the network — only for the same bug to trigger a second halt hours later. A third halt followed as residual issues from the patch surfaced.
SUI Price Impact
SUI dropped 8% from pre-outage levels, falling to critical support near $0.90. Over $2 million in leveraged long positions were wiped out across exchanges as the price declined.
CME Futures Debut Overshadowed
The outages were particularly poorly timed. Sui CME Group futures contracts debuted on the same days the network was struggling with stability, undermining what should have been a major institutional catalyst.
FAQ
Was any user funds lost during the Sui outages? No. The halt froze block production but did not compromise any user funds, smart contracts, or private keys.
Has the v1.72 bug been fully fixed? The Sui team deployed patches and validators have applied them. They describe the current fix as a long-term solution.
How does this affect Sui CME futures launch? The outages coincided with Sui CME futures debut, which may slow institutional adoption.
