Starknet Must Act Quickly to Avoid Market Downside

The closest precedent dates back to September 2025, when Starknet suffered an outage that lasted roughly nine hours. During that episode, STRK’s price fell by about 5%, showing that prolonged disruptions can spill over into the market when recovery is delayed. The difference this time will depend on response speed and the perceived level of control over the incident.

At the time of writing, Starknet (STRK) holds a market capitalization of $444 million and a circulating supply of 5.04 billion tokens. Over the past 24 hours, the token posted a 0.93% increase, reaching $0.0891. Trading volume also rose by 29%, without creating meaningful pressure on the price. The data suggests the market is waiting for clarity before adjusting positions.

Prioritizing User Trust

This incident puts the operational reliability of layer-2 solutions under scrutiny. Scalability loses credibility when block production becomes unstable. Trust does not break from a single failure, but it erodes steadily if disruptions repeat over time.

Starknet is now racing against the clock. How quickly the issue is resolved and how clear the post-incident report is will matter more than the outage itself
