Types

type Network

type Network struct {
	// ChainID represents chainID of the network.
	ChainID int64
	// Name represents name of the network.
	Name string
	// ForkVersionHex represents fork version of the network in hex.
	ForkVersionHex string
}

Network contains information about an Ethereum network.
