Sui deploys permanent fix after patch triggered second mainnet halt

Sui Network’s mainnet is back online after validators rolled out a long-term fix to address repeated halts tied to the gas-charging logic in release 1.72. The chain stalled twice over two days. An interim patch pushed Thursday included a known low-probability flaw; on Friday, the network encountered a related variant and halted again. Validators have now deployed the permanent solution, with more than two-thirds upgraded, and on-chain activity has resumed. Sui said no user funds were lost in either incident. The SUI native token dropped as much as 8% during the disruption. A full post-incident review is still pending.
