 ## Multichain support
 
-In Hardhat 2, you can only configure a single Hardhat network, which always behaves like Ethereum Mainnet. Hardhat 3 introduces chain types, letting you choose which kind of chain you want to simulate. And you can configure multiple Hardhat networks, each with its own chain type.
+Hardhat 2's development network always behaves like Ethereum Mainnet. Hardhat 3 removes this limitation, letting you choose which kind of chain you want to simulate. And, unlike Hardhat 2, you can configure multiple Hardhat networks, each with its own chain type.
 
-The first version will have support for Ethereum Mainnet and OP Mainnet, plus a "generic" chain type that can be used as a fallback for chains that are not yet supported.
+The initial release includes first-class support for Ethereum Mainnet and OP Mainnet, providing more realistic simulations of these networks. We'll gradually add new chain types over time. In the meantime, a generic chain type can be used as a fallback for networks that are not yet supported. This generic chain type behaves the same as Hardhat Network in Hardhat 2 and works with all of Hardhat 3's new features.
