Types

type AppTool

type AppTool struct {
	agtypes.BaseAppTool
	// contains filtered or unexported fields
}

func (*AppTool) BackupLastBlock

func (t *AppTool) BackupLastBlock(branchName string) error

func (*AppTool) Init

func (t *AppTool) Init(datadir string) error

func (*AppTool) LastHeightHash

func (t *AppTool) LastHeightHash() (def.INT, []byte)

func (*AppTool) SaveNewLastBlock

func (t *AppTool) SaveNewLastBlock(fromHeight def.INT, fromAppHash []byte) error

type CreateContractTx

type CreateContractTx struct {

}

CreateContractTx wraps ethereum tx bytes with the abi json bytes for this contract

func DecodeCreateContract

func DecodeCreateContract(bs []byte) (*CreateContractTx, error)

type EVMApp

type EVMApp struct {
	agtypes.BaseApplication
	agtypes.CommApplication

	civil.EventAppBase
