The Sui Foundation on Sunday published a post-mortem on the three mainnet outages that took its Layer 1 down on May 28 and 29, pinning the first two halts on a gas-charging bug introduced by the v1.72 "address balances" upgrade and the third on a separate randomness-state fault exposed when validators restarted to install an interim fix the team admits it shipped knowing it carried a low-probability halt risk.
SUI, the network's native token, slid 6.6% in the 24 hours after the post-mortem and is down 18.5% over seven days at $0.82, trimming Sui's market capitalization to $3.31 billion, per CoinGecko. The chain holds $479.66 million in total value locked, the thirteenth-largest among networks tracked by DefiLlama, behind Avalanche and ahead of Monad. Sui-based DEXs cleared $77.33 million in 24-hour volume on Sunday — led by DeepBook V3 at $26.69 million.
Last week, Sui restarted after back-to-back halts tied to the same 1.72 release. It is also one of the more granular Layer 1 incident reports published this year, naming specific code paths and conceding the validator network briefly ran on a fix Mysten Labs engineers knew might fail.
