Security Update: We are responding to a security incident affecting part of our infrastructure.
At this time, we have identified no immediate threat to MetaMask wallets.

MetaMask said it has not found any immediate threat to its wallets. It is working with outside partners and security advisors to fix the issue.
The company has not said what caused the incident. It only described it as affecting part of its infrastructure.
MetaMask manages over three billion dollars in staked Ether through its systems. This makes it one of the largest gateways for people who want to stake Ethereum.
What MetaMask Is Doing About It
As a precaution, MetaMask is exiting validators connected to its non-custodial staking operations. The company said this move is being done in coordination with clients and partners.
MetaMask reminded users that its staking service is non-custodial. This means the company does not hold withdrawal keys for stake on behalf of its clients.
MetaMask said it will continue watching the situation. It plans to share more updates when there is new information.
Cointelegraph reached out to MetaMask for more detail but did not get an immediate response.
Lido Confirms Validator Exits From Its Protocol
Lido, a separate staking protocol, gave its own account of the situation. Lido said MetaMask Staking began taking steps to protect client assets tied to its Ethereum validators.
This included exiting validators operated through the Lido protocol. The exits started on Wednesday.
MetaMask Staking works through MetaMask Portfolio in three ways. These are pooled staking, validator staking, and liquid staking through Lido and Rocket Pool.
Lido said the last of the affected validators are expected to exit by October 7.
A developer at Lido Finance, Will Shannon, explained what happens next. He said Ether exited from the validators will return to the protocol over time.
This process includes an exit, withdrawal, and re-entry cycle. Shannon said this is expected to take close to 45 days because of a long entry queue.
The delay is due to the number of validators currently waiting to join the network. This queue affects how fast new validators can be added back.
MetaMask has not shared a timeline for when the underlying infrastructure issue will be fully resolved. The company said contract security remains a top focus going forward.
For now, the main facts are clear. MetaMask found a security issue in part of its infrastructure, it sees no threat to wallets, and it is pulling back validators from staking as a safety step while it works with partners to sort out the cause.
