The failure was within the module that calculates and fees the commissions for every transaction, in response to Sui.
It’s not the primary time: Sui already recorded related interruptions in November 2024 and January 2026.
The Sui community was paralyzed for greater than 5 hours yesterday, Might 28, after a bug in its software program model 1.72 stopped the processing of all transactions, in response to the crew behind the community. The SUI token, the community’s native foreign money, fell 6.25% on the day, from $0.96 to a low within the $0.90 space.
The developer crew warned about the issue in a primary submit on X that famous: “The Sui mainnet is experiencing a downtime. Sui’s core crew is actively engaged on an answer. “Transactions could also be paused presently.”
Later, in a second one, printed after the resumption, he specified the trigger: “Exercise on the Sui essential community resumed after a stoppage brought on by a vital bug within the fuel charging logic launched by model 1.72.»
The fuel charging module is the software program element that robotically calculates and deducts commissions from every transaction earlier than processing it. When that module fails with a crash error, that’s, an error that abruptly stops program execution as an alternative of dealing with it and persevering with, node can not advance to subsequent blockand if that occurs concurrently on the validators holding up the community, processing stops fully. That was the mechanism that paralyzed Sui.
The crew introduced, in response to its publication, that it’ll share “a full evaluation of the incident within the coming days,” with out specifying a date.
It’s not the primary time that Sui stops working
In November 2024, the community was greater than two hours with out producing blocks after a failure. On that event, as reported by CriptoNoticias, the SUI token fell greater than 7% on the day.
Likewise, in January 2026 the sample was repeated: a brand new arrest of a number of hours was confirmed by the community builders.
The buildup of no less than these three interruptions raises a query in regards to the operational resilience of the community in a phase the place Sui competes with different chains akin to Solana, Aptos and Avalanche utilizing processing capability as a central argument.
