Ethereum News Today: Is Your ETH Safe After Latest Security Update?

Ethereum News: MetaMask Security Update, Blast Exit and ETH Price

Today's Ethereum news brings two big stories. Consensys founder Joseph Lubin gave a security update, and the Blast Layer 2 network announced it will shut down. 

Lubin says there is no sign that MetaMask wallets or customer funds were hit. Blast users, however, face a withdrawal deadline of October 26, 2026. ETH trades near $2,680 after a choppy 24 hours.

At a Glance

• MetaMask security: Lubin says no wallets, funds, recovery phrases, or private keys were affected, based on the investigation so far.

• Validator response: Validator keys were rotated as a precaution. Affected validators must exit and rejoin the staking queue.

• Blast Network shutdown because maintenance costs exceed revenue.

• Deadline: Users can use the normal interface until October 26, 2026.

• ETH price is at $2,679.62, down 1.8% in 24 hours, per CoinGecko.

MetaMask Security Incident: What Joseph Lubin Confirmed

Lubin said part of his team's infrastructure was affected by a security incident. In a post on October 3, he wrote that the investigation had found no sign of harm to MetaMask wallets or customer funds.

He also said user Secret Recovery Phrases and private keys were not involved. Under self-custody, users control their own keys. The team shared details with partners, agreed on a response and then went public.

This part of the Ethereum news comes with a caveat. Full technical details have not been released. A security incident in infrastructure does not automatically mean wallet keys were stolen. Still, the findings could change as the investigation continues.

Why Validator Key Rotation Matters for ETH Stakers

Ethereum validators use two different kinds of keys. Signing keys propose blocks and vote on the state of the chain. Withdrawal keys control access to the staked ETH itself.

Lubin said his team and its partners rotated validator keys as a precaution. They do not hold customer withdrawal keys. That means a problem in validator infrastructure should not allow anyone to move the underlying ETH.

The rotation still has a cost. Affected validators must leave the staking queue and join it again, which takes time. The validator exits may lead to missed rewards.

So stakers face two separate questions. First, are the keys that control withdrawals safe? Second, will staking be interrupted? Wallet safety, validator uptime and rewards are related, but they are not the same risk.

Blast Shutdown: What Users Need to Know Before October 26

Ethereum L2 Network Blast will cease operations. The team says upkeep costs are higher than the revenue the network earns, and it sees no clear path to sustainability for now.

It launched in November 2023 and raised $20 million at launch. Paradigm and Standard Crypto were among its investors. The network was known for yield features on ETH and stablecoins.

Users are asked to move their assets back to Ethereum mainnet. The withdrawals will pause for about one week while the team unwinds assets held through Lido. After that, the waiting period will drop to 24 hours.

Until the October 26 deadline, users can withdraw through the regular interface. After that date, assets can still be recovered through the Blast Bridge contract on Ethereum. Users will need to interact with that contract directly. Always check official instructions before signing any transaction.

Ethereum Price Today: ETH Falls 1.8% Near $2,680

Ethereum (ETH) is trading at $2,679.62 on October 3, 2026, down 1.8% over the past 24 hours, according to the supplied CoinGecko data. It climbed toward $2,768 before falling to around $2,653 and recovering slightly. The decline puts it below the $2,700 mark, which traders will be watching as the price moves.

For investors, the latest drop means the value of their ETH holdings has decreased over the past day. It currently has a market capitalization of around $327.17 billion, with $15.93 billion in 24-hour trading volume. Traders will be watching whether it can move back above $2,700 or fall toward its recent low near $2,653.

What Blast Network Shutdown Means for Ethereum Layer 2 Users

Attracting deposits does not guarantee a network can pay its own way. Layer 2 networks handle transactions off mainnet and rely on Ethereum for settlement. Each one can have its own withdrawal steps.

Three points matter for users:

• Check where your assets sit. ETH on mainnet is not the same as it held through a Layer 2 app or bridge.

• Know the withdrawal steps. Moving funds back may involve waiting periods and fees.

• A deadline is not instant loss. The funds stay recoverable after October 26, but the process is harder.

Blast's exit does not prove that mainnet or other Layer 2 networks face the same outcome.

Key Timeline: MetaMask Response, Blast Withdrawals and ETH Price

• Sep 30, 2026: MetaMask discloses an infrastructure incident and begins precautionary validator exits.

• Oct 2, 2026: Blast announces its shutdown and asks users to migrate assets.

• Oct 3, 2026: Lubin gives his update. ETH trades near $2,680.

• About one week later: Blast pauses withdrawals while it unwinds Lido assets.

• Oct 26, 2026: Blast's regular withdrawal interface deadline.

Conclusion

Today's Ethereum news covers a security incident, a Layer 2 closure, and a modest price dip. Lubin separates the infrastructure issue from user wallets and withdrawal keys. Crypto users should plan their exit before October 26 rather than assume funds will move on their own. Next, watch for more technical details on the incident, validator updates, and how it carries out its withdrawal plan.
