Recently, Optimism, the second-layer expansion network of Ethereum, officially tweeted that Optimism Kovan has been deprecated and replaced by Optimism Goerli.
Optimism’s Kovan testnet will be fully retired on October 5th. To encourage all projects to migrate before this deadline, the rate limit for the Optimism Kovan public endpoint will be lowered.
Earlier on July 1st, Optimism decided to phase out the Kovan testnet and planned to migrate the project to Goerli before August 15th.
