This release enhances type extensibility and includes a minor performance improvement for development networks.

This release introduces support for verifying contracts using Blockscout as a verification provider. To verify a contract using Blockscout, simply add the following to your Hardhat configuration:

blockscout: {
  enabled: true,
}

Currently, only mainnet and sepolia are included as built-in chains, but you can add other networks using the customChains property in the Hardhat config.
