Optimism tweeted that Kovan has been deprecated by the Ethereum community. In order to continue to provide a stable test network for the ecosystem and keep pace with Ethereum after the merger, Optimism also decided to eliminate the Kovan test network.
In addition, Optimism has created a migration status page that will be continuously updated to track the migration of the ecosystem to Goerli, and Optimism plans to fully migrate all projects to Goerli by August 15, officials said.
