Functions

func RegisterInterfaces

func RegisterInterfaces(registry codectypes.InterfaceRegistry)

RegisterInterfaces register the module interfaces to protobuf Any.

Types

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) CreateMsgCreateClient

func (pr *Prover) CreateMsgCreateClient(clientID string, dstHeader core.Header, signer sdk.AccAddress) (*clienttypes.MsgCreateClient, error)

CreateMsgCreateClient creates a CreateClientMsg to this chain

func (*Prover) GetLatestFinalizedHeader

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

GetLatestFinalizedHeader 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 (*Prover) Init

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

Init initializes the chain

func (*Prover) ProveState

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`

func (*Prover) SetRelayInfo

func (pr *Prover) SetRelayInfo(path *core.PathEnd, counterparty *core.ProvableChain, counterpartyPath *core.PathEnd) error

SetRelayInfo sets source's path and counterparty's info to the chain

func (*Prover) SetupForRelay

func (pr *Prover) SetupForRelay(ctx context.Context) error

SetupForRelay performs chain-specific setup before starting the relay

func (*Prover) SetupHeadersForUpdate

func (pr *Prover) SetupHeadersForUpdate(dstChain core.ChainInfoICS02Querier, latestFinalizedHeader core.Header) ([]core.Header, error)

SetupHeadersForUpdate returns the finalized header and any intermediate headers needed to apply it to the client on the counterpaty chain The order of the returned header slice should be as: [<intermediate headers>..., <update header>] if the header slice's length == 0 and err == nil, the relayer should skips the update-client

type ProverConfig
