We use TypeName rather than Type to reserve 'Type' for a possible future ABI type the can hold an ABI-native type mapping

const (
	// We don't need to be exhaustive here, just make what we used strongly typed
	AddressTypeName TypeName = "address"
	IntTypeName     TypeName = "int"
	Uint64TypeName  TypeName = "uint64"
	Bytes32TypeName TypeName = "bytes32"
	StringTypeName  TypeName = "string"
	BoolTypeName    TypeName = "bool"
