TEE enclave failure caused the Base card to be down for 30 hours. The 7-day challenge period indeed gave users some buffer, but a single point of failure at the infrastructure layer still makes people sweat.

BlockBeats reports that a vulnerability was found during an upgrade, and the Base network status update has been stalled for more than 30 hours. Because withdrawing to the Ethereum mainnet requires an approximately 7-day challenge period, ordinary users have not yet perceived any obvious impact. The official status page says the problem is caused by a TEE enclave failure, which has interrupted the network proposal process and thereby affected status updates. At present, withdrawals on the Base mainnet are delayed, and the team is working on repairs; other core network components are not directly affected.
