Starknet’s mainnet is once again facing an outage, continuing a troubling trend of technical hiccups for the Ethereum layer-2 network as it enters 2026.
Key Takeaways
- Starknet experienced a fresh mainnet outage caused by slow block production, with the network offline for over two hours.
- The root cause remains unidentified, though engineers are actively investigating and prioritizing restoration of core operations.
- This marks at least the third major disruption in the past year, raising persistent concerns over Starknet’s reliability.
- Despite the downtime, the STRK token price remained relatively stable, posting a 0.93% gain and reaching $0.0891.
What Happened?
Starknet, a zero-knowledge rollup-based layer-2 solution for Ethereum, experienced yet another mainnet disruption as it kicked off the new year. The outage, caused by slow block production, brought core transaction and contract execution to a halt. The team confirmed the incident via its official channels, stating that engineers were working to restore functionality as soon as possible.
At the time of reporting, users and developers were facing delays and limited functionality, while the project had yet to issue a full diagnostic report or technical breakdown of the failure.
Starknet is currently experiencing downtime. Our team is actively investigating the issue and working to restore full functionality as quickly as possible. Thank you for your patience.

Starknet’s Ongoing Struggle With Network Stability
Starknet’s latest outage is not an isolated event. Over the past year, the network has experienced several major disruptions that have cast a shadow over its operational reliability.
- In September 2025, an upgrade named Grinta (v0.14.0) led to a significant outage lasting approximately nine hours. Block production halted, and the chain underwent two reorganizations, which forced users to resubmit transactions and caused around an hour of blockchain activity to be reverted.
- Earlier in 2025, another multi-hour outage tied to sequencer issues was logged by external trackers. These incidents marked a recurring issue with the stability of Starknet’s core infrastructure.
An incident report following the Grinta outage pointed to failures in Ethereum RPC providers and bugs affecting the sequencer, prompting the team to commit to architectural changes and expanded monitoring.
Market Holds Steady but Confidence Wavers
Surprisingly, STRK’s price showed resilience amid the latest disruption, posting a 0.93% gain and reaching $0.0891, with trading volume increasing by 29%. This contrasts with the September 2025 outage, which saw a roughly 5% drop in token value. Analysts believe the market is waiting for more clarity before reacting, highlighting the importance of a transparent and swift resolution.
As of now, Starknet holds a market capitalization of $444 million, with a circulating supply of 5.04 billion tokens. The muted price reaction suggests that while traders are not panicking, confidence is fragile and could shift quickly if problems persist.
A Bigger Test for Layer-2 Trust
This incident underscores the broader issue of trust in layer-2 networks. While ZK-rollups promise scalability and lower costs, repeated outages undermine their value proposition. Starknet has promoted its infrastructure as critical for applications across DeFi, gaming, and even Bitcoin-related financial use cases (BTCFi). But network uptime is a non-negotiable baseline for these ambitions to succeed.
The team has so far avoided naming a specific root cause for the current issue, instead focusing on restoring essential services. The speed and clarity of the post-mortem report may matter more than the outage itself when it comes to restoring user trust.
CoinLaw’s Takeaway
I’ve been following Starknet for a while now, and honestly, this kind of repeat disruption really tests the patience of developers and users alike. In my experience, trust in infrastructure is like oxygen in Web3. You barely notice it when it’s there, but once it disappears, everyone starts gasping. Starknet’s tech is promising, but promise alone won’t cut it anymore. The next 48 hours are crucial. If the team can deliver a transparent diagnosis and real fixes, they might salvage confidence. If not, I wouldn’t be surprised to see projects start looking elsewhere.
