Sui's blockchain went dark for the third time in under two days on Friday, halting all user transactions while validators scrambled to patch a deep-seated bug in gas charging logic. The latest failure hit around 4:30 PM EDT during an epoch transition, sending SUI's price tumbling to $0.9035 on Binance — an 8% decline since Thursday and a 16% drop over the past week. The network was fully restored after validators deployed fixes, but not before leveraged traders took a heavy hit.
The outage that broke the buck
This wasn't a minor blip. The May 29 stoppage followed two earlier interruptions in the same 48-hour window, making it Sui's third significant disruption of 2026. All three trace back to changes meant to enable zero-fee stablecoin transfers. The team introduced a crash bug in version 1.72 of the client and a latent bug in failure state preservation during validator restarts. When the epoch turned over Friday afternoon, those bugs combined to stall the network.
Validators remained active — they just couldn't process user transactions. No user funds were lost, the team confirmed. But the timing couldn't be worse: Sui had already seen a six-hour consensus divergence in January and a congestion-related outage in November 2024.
$1.88 million in liquidations
The price action was brutal. SUI had been clinging to the $1.00 support level, but the repeated outages broke it — the first time that level has given way since early 2024. According to liquidation data, $1.88 million in SUI positions were wiped out, with $1.72 million coming from longs. Traders betting on a price recovery after the first two outages were disproportionately caught.
The 8% single-day drop and 16% weekly slide reflect growing impatience with the network's reliability.
What went wrong under the hood
The root cause is a pair of bugs introduced when Sui's developers redesigned gas charging to support zero-fee stablecoin transfers — a feature meant to attract DeFi liquidity. The first bug crashed validators on certain transaction types; the second failed to preserve error states during restarts, making it impossible for the network to recover cleanly. Validators deployed patches addressing both issues and the affected epoch was restored.
Whether the fixes hold will become clear in the coming days. The network has now had three major incidents in 2026, and users are watching closely to see if this latest patch is a permanent solution or just another temporary stopgap.
