The Optimism (OP) network is poised for a temporary suspension of Ethereum (ETH) withdrawals on Thursday, February 15, starting at 9:00 ET.
The scheduled one-hour interruption is key to a broader strategy. It aims to enhance the network’s defense against security threats.
Optimism Network Plans to Pause Ethereum Withdrawals
The pause, announced by Optimism, will facilitate essential maintenance work and the implementation of a significant protocol upgrade.
“On Thursday, Feb 15th 9:00am ET (6:00am PT), OP Mainnet will be paused as part of a planned maintenance window lasting one hour. During the pause withdraws to L1 will be rejected. The network will be unpaused at 10:00am ET (7:00am PT), Optimism announced.
OP Labs first proposed the upcoming upgrade on January 25. A key part is the new SuperchainConfig contract. This innovative feature is meant to grow with the Superchain, adding new abilities over time. Not to mention, this contract has been working well on OP Sepolia since December 11, 2023.
At the heart of this upgrade lies the enhanced ability to manage security incidents across all OP Chains effectively. The Superchain, with its intricate web of interconnected chains, indeed presents unique security challenges.
