Functions

func CallMethod 

func CallMethod(ctx context.Context, rpc RPCClient, signer TXSigner, from, addr string, value json.Number, methodABI *ethbinding.ABIMethod, msgParams []interface{}, blocknumber string) (map[string]interface{}, error)

func GetOrionPrivacyGroup 

func GetOrionPrivacyGroup(ctx context.Context, rpc RPCClient, addr *ethbinding.Address, privateFrom string, privateFor []string) (string, error)

GetOrionPrivacyGroup resolves privateFrom/privateFor into a privacyGroupID

func GetOrionTXCount 

func GetOrionTXCount(ctx context.Context, rpc RPCClient, addr *ethbinding.Address, privacyGroup string) (int64, error)

func GetSolcArgs 

func GetSolcArgs(evmVersion string) []string

func ProcessRLPBytes 

func ProcessRLPBytes(args ethbinding.ABIArguments, retBytes []byte) map[string]interface{}

type RPCClientAll 

type RPCClientAll interface {
	RPCClosable
