type Module 

type Module struct{}

func (Module) GetCmd 

func (Module) GetCmd(ctx *config.Context) *cobra.Command

GetCmd returns the command

func (Module) Name 

func (Module) Name() string

Name returns the name of the module

func (Module) RegisterInterfaces 

func (Module) RegisterInterfaces(registry codectypes.InterfaceRegistry)

RegisterInterfaces register the module interfaces to protobuf Any.

type Prover 

type Prover struct {
	// contains filtered or unexported fields
}

func NewProver 

func NewProver(chain *ethereum.Chain, config ProverConfig) *Prover

func (*Prover) CheckRefreshRequired added in v0.2.2 

func (pr *Prover) CheckRefreshRequired(counterparty core.ChainInfoICS02Querier) (bool, error)

func (*Prover) CreateInitialLightClientState added in v0.2.5 

func (pr *Prover) CreateInitialLightClientState(height ibcexported.Height) (ibcexported.ClientState, ibcexported.ConsensusState, error)

CreateInitialLightClientState returns a pair of ClientState and ConsensusState based on the state of the self chain at `height`. These states will be submitted to the counterparty chain as MsgCreateClient. If `height` is nil, the latest finalized height is selected automatically.

func (*Prover) GetLatestFinalizedHeader 

func (pr *Prover) GetLatestFinalizedHeader() (headers core.Header, err error)

buildLatestFinalizedHeader returns the latest finalized header on this chain The returned header is expected to be the latest one of headers that can be verified by the light client

func (pr *Prover) Init(homePath string, timeout time.Duration, codec codec.ProtoCodecMarshaler, debug bool) error

Init initializes the chain

func (pr *Prover) ProveHostConsensusState(ctx core.QueryContext, height ibcexported.Height, consensusState ibcexported.ConsensusState) (proof []byte, err error)

ProveHostConsensusState returns an existence proof of the consensus state at `height` This proof would be ignored in ibc-go, but it is required to `getSelfConsensusState` of ibc-solidity.

func (*Prover) ProveState added in v0.2.0 

func (pr *Prover) ProveState(ctx core.QueryContext, path string, value []byte) ([]byte, clienttypes.Height, error)

ProveState returns the proof of an IBC state specified by `path` and `value`
