Ethereum Layer-2 community Starknet reportedly suffered recent mainnet downtime, including one other outage to a rising listing of reliability scares in 2025. Whereas Starknet’s token worth information stayed restricted at press time, the community nonetheless secures round $548 million in worth, so each hour offline traps actual cash and freezes actual trades.
This comes as Ethereum scaling options race to draw customers and builders, at the same time as outages remind everybody that quicker and cheaper doesn’t at all times imply safer.

What Simply Occurred to Starknet, And Why Ought to On a regular basis Customers Care?
Starknet is a so‑known as Layer‑2 community for Ethereum. Consider it as an specific lane constructed on high of the Ethereum freeway that batches many transactions collectively, then settles the outcome again to Ethereum for safety. It makes use of a expertise known as a ZK‑rollup, which depends on superior cryptography to show that batched transactions are legitimate with out displaying each step on Ethereum itself.
In 2025, that specific lane saved stalling. Starknet’s personal incident report, earlier outages tied to its Grinta (v0.14.0) improve precipitated sequencer failures and points with older Cairo0 code. The sequencer is the piece of software program that orders transactions on Starknet, just like a visitors cop deciding who goes first at a busy junction.
When that visitors cop fails, the whole lot backs up. In September 2025, Starknet’s downtime lasted so long as 9 hours and even compelled two transaction reorganizations that erased roughly an hour of community historical past.
Throughout a reorg, the chain “rewinds” to a earlier state and builds a brand new model, which might cancel trades and transfers that customers thought have been remaining. Meaning a swap you made or a mortgage you repaid on Starknet may vanish and want a second strive.

Starknet now ranks amongst Ethereum’s bigger Layer‑2s with about $548 million locked on it. That cash sits in DeFi apps, NFT markets, and wallets that each one rely upon the community staying stay.
So when Starknet goes darkish, customers can not transfer funds, shut positions, or react to cost swings, whereas markets elsewhere on Ethereum preserve shifting with out them.
In order for you a refresher on how Ethereum scaling works extra broadly, 99Bitcoins lined it intimately when Ethereum stablecoin transfers hit $8 trillion in quantity on the Ethereum Network. That big-picture view helps you see why these layers matter a lot.
How Does This Outage Change the Layer‑2 Race on Ethereum?
Starknet competes with different Ethereum Layer‑2s like Arbitrum, Optimism, zkSync, and Coinbase’s Base. Every affords decrease charges and quicker confirmations than the Ethereum mainnet, however every one continues to be an unbiased community with its personal dangers.
Customers select them like they select banks or brokers: whoever feels safer and smoother over time wins deposits and quantity.

Repeated outages chip away at Starknet’s reliability story. Whereas it markets superior cryptography and powerful Ethereum safety, customers expertise one thing less complicated: “Can I ship my cash after I have to?” Networks like Arbitrum and Optimism have problems with their very own, however they didn’t undergo the identical sample of lengthy downtimes in 2025. That distinction shapes the place builders launch new apps and the place customers park funds.
In the meantime, the ZK‑rollup sector retains altering. ZKsync Lite will retire in 2026 as groups migrate to newer variations. When base infrastructure modifications that quick, outages remind everybody that this tech continues to be younger.
Even when Ethereum’s personal upgrades, like those we lined in our information to imminent Ethereum upgrades, intention to make the primary chain extra environment friendly, the Layer‑2s on high nonetheless have to show they will keep on-line.
Starknet additionally pushes towards decentralizing its sequencer in order that one entity now not controls transaction ordering. Latest incidents raised doubts about whether or not the community can safely make that leap. A rushed or buggy decentralization may unfold instability as an alternative of lowering it, particularly whereas billions in worth rely upon that infrastructure.
For Ethereum itself, these hiccups reduce each methods. On the one hand, they spotlight the dangers of constructing on recent infrastructure. Alternatively, they present the demand for scaling and the strain on groups to enhance rapidly, which strains up with the long-term targets Vitalik Buterin set for the community’s progress that we mentioned in our piece on Ethereum.

What Ought to Starknet And Ethereum Customers Really Do Now?
Earlier than you bridge funds into Starknet, ask three easy questions. One: Do I perceive the chance that my cash is likely to be quickly caught? Two: Do I really need the decrease charges for this commerce or yield technique? Three: Is that this cash I can afford to depart alone if one thing breaks for just a few hours or perhaps a day?
Merchants and DeFi customers also needs to watch incident experiences just like the one Starknet posted on its blog. If I have been an investor, I’d watch carefully how the crew handles this incident over the following few days.
Groups that publish clear timelines, fixes, and observe‑up plans normally deal with issues higher over time than groups that keep quiet. However transparency doesn’t take away danger. It solely helps you choose how severely a venture treats your deposits.

For learners selecting the place to start out with Ethereum DeFi, a easy rule helps: favor stability first, pace second. Find out how Ethereum mainnet, main Layer‑2s, and DeFi apps work earlier than you stretch for additional yield on much less‑examined networks.
Starknet’s subsequent strikes, how rapidly it stabilizes the sequencer, how brazenly it experiences fixes, and the way it handles decentralization, will determine whether or not customers belief it with extra of their ETH. As Layer‑2 competitors heats up, these reliability tales will matter as a lot as APY and costs.
