Polygon zkEVM previews an Etrog upgrade on the X platform that will make it more relevant to the Ethereum mainnet. This upgrade will make Polygon zkEVM a Type 2 ZK-EVM, allowing developers to deploy their code on Polygon ZK-EVM just like on Ethereum. With this update, developers can simply copy and paste the code without making additional modifications. According to an update shared, the 10-day timelock for the Etrog upgrade has been triggered and Polygon developers can join the testing phase of Cardona, Polygon-zkEVM’s new Sepolia-anchored testnet.
