MetaMask stressed that its staking operations are non-custodial and that it does not manage withdrawal keys for clients’ staked assets. In staking, validators operate the infrastructure that helps process transactions and secure a proof-of-stake network.
The company is working internally and with external partners and security advisers to address the incident. It said monitoring would continue, but the notice did not give a timetable for completing remediation or restoring the affected operations.
MetaMask did not disclose the incident’s cause, the number of affected validators or the value of stake involved. The statement also did not specify whether any funds had been lost. Its assessment of wallet safety remains qualified by the ongoing investigation.
