Ethereum ETH $4 286 24h volatility: 2.6% Market cap: $516.84 B Vol. 24h: $29.43 B Layer 2 blockchain, Starknet STRK $0.12 24h volatility: 3.8% Market cap: $492.99 M Vol. 24h: $28.31 M , is back online after suffering an unexpected outage that left users unable to send or confirm transactions for more than four hours.
Developers have confirmed that block production has resumed and services are running normally again.
The disruption began shortly after Starknet’s Grinta upgrade, also known as version 0.14.0, was deployed. The upgrade was meant to improve performance, but instead the network stopped producing blocks beyond #1961878.
While developers had issued a warning for a brief 15-minute pause, the outage stretched into several hours, leaving transactions stuck and wallets disconnected.
Between 2:23 am and 4:36 am UTC, transactions submitted to the network were not processed.
Starknet is currently experiencing downtime.
Our team is actively investigating the issue and working to restore full functionality as quickly as possible.
We’ll share updates as soon as we know more.

To restore services, developers had to initiate a rollback, or “reorg,” to block #1960612. This meant that all transactions beyond that point were erased and now need to be resubmitted by users.
Starknet is back online and fully operational.
Block production is back to normal. Most RPC providers are up-and-running, and the remaining ones will upgrade shortly.
To restore service, transactions submitted between 2:23am and 4:36am UTC were not processed.
A reorg from block… https://t.co/nrziivCiuK— Starknet (@Starknet) September 2, 2025
RPC providers are also gradually coming back online, ensuring wallet and dApp connections are stable again.
The outage also affected the network’s token. STRK fell about 4.5% to $0.1204 during the disruption before recovering slightly. At the time of writing, the penny crypto is trading around $0.1234 with a market cap of $503 million.
Meanwhile, developers have promised to release a full incident report, including a root cause analysis and long-term fixes to prevent similar issues.
While the Grinta upgrade caused short-term pain, it is also a step in Starknet’s long-term strategy to move closer to decentralization. Currently, the network still relies heavily on StarkWare, the company running its transaction sequencer.
The Grinta upgrade is expected to make the network more efficient, reliable, and decentralized.
Starknet’s roadmap outlines a gradual shift toward distributing block validation and production across multiple independent nodes. The ultimate goal is to replace centralized sequencing with decentralized sequencing and proving mechanisms.
This means network security and transaction validation would eventually be maintained by a broader community, rather than being reliant on one company.
