The Sui network will restart after a 6-hour interruption
The Sui Network is back online after a six-hour shutdown on Thursday due to a bug introduced in an update in 2026, marking the second break of the Layer-1 blockchain.
Sui posted on X on Thursday that activity on the mainnet was halted after “due to a crash bug in the gas charging logic introduced in the 1.72 release. A full incident review will be shared in the coming days.”
Sui previously shared that the blockchain is “experiencing a network stall” and that transactions may be halted until a fix is issued.
According to the Network Status Indicator, the outage lasted 5 hours and 55 minutes. Sui mainnet authenticators are still listed as having “degraded performance”.

This is the second time this year that the Sui blockchain has taken the network offline for more than six hours, following a similar incident in January. Another incident occurred in November 2024, when all validators were stuck in a crash loop for around two and a half hours, preventing transactions from going through.
Sui is the 13th largest blockchain in total, with $542 million locked in and hosting 137 protocols.
Sui Token will decrease by 6.6% before returning
The Sui (SUI) token fell 6.6% to a low of 90 cents during the break. It has since recovered slightly and was trading at 93 cents as of early Friday.

Earlier this month, the token surged 50% to $1.41 after several positive developments, with a Nasdaq-listed company holding a large portion of its supply and developers announcing upcoming features including zero-fee stablecoin transfers and private transactions.
Swi launched the network in May 2023, with the aim of being scalable and able to quickly process transactions for financial institutions.

Adeniyi Abiodun, co-founder of Mysten Labs, the developer of the Sui network, announced the imminent release of zero-fee stablecoin transfers in Consensus 2026 and reiterated plans to add a private-transaction feature.
Not all major crypto disruptions this year have come from technical issues. Drift Protocol, a decentralized cryptocurrency exchange, was hacked in April, causing it to temporarily halt deposits and withdrawals.
Kelp, a liquid staking protocol, was targeted by a cyber attack in April, prompting the platform to suspend smart contracts for staking (rsETH) while it investigates the incident.
