Functions

func ConstructDialOptions 

func ConstructDialOptions(
	maxCallRecvMsgSize int,
	withCert string,
	grpcRetries uint,
	grpcRetryDelay time.Duration,
	extraOpts ...grpc.DialOption,
) []grpc.DialOption

ConstructDialOptions constructs a list of grpc dial options

func CreateSignedVoluntaryExit 

func CreateSignedVoluntaryExit(
	ctx context.Context,
	validatorClient iface.ValidatorClient,
	signer iface.SigningFunc,
	pubKey []byte,
	epoch primitives.Epoch,
) (*ethpb.SignedVoluntaryExit, error)

func CurrentEpoch 

func CurrentEpoch(genesisTime *timestamp.Timestamp) (primitives.Epoch, error)

func ProposeExit 

func ProposeExit(
	ctx context.Context,
	validatorClient iface.ValidatorClient,
	signer iface.SigningFunc,
	pubKey []byte,
	epoch primitives.Epoch,
) error

ProposeExit performs a voluntary exit on a validator. The exit is signed by the validator before being sent to the beacon node for broadcasting.

func SubmitValidatorRegistrations 

func SubmitValidatorRegistrations(
	ctx context.Context,
	validatorClient iface.ValidatorClient,
	signedRegs []*ethpb.SignedValidatorRegistrationV1,
	validatorRegsBatchSize int,
) error

SubmitValidatorRegistrations signs validator registration objects and submits it to the beacon node by batch of validatorRegsBatchSize size maximum. If at least one error occurs during a registration call to the beacon node, the last error is returned.

NewValidatorService creates a new validator service for the service registry.

func (*ValidatorService) GenesisInfo 

func (v *ValidatorService) GenesisInfo(ctx context.Context) (*ethpb.Genesis, error)

GenesisInfo queries the beacon node for the chain genesis info containing the genesis time along with the validator deposit contract address.

func (*ValidatorService) InteropKeysConfig 

func (v *ValidatorService) InteropKeysConfig() *local.InteropKeymanagerConfig

InteropKeysConfig returns the useInteropKeys flag.

func (*ValidatorService) Keymanager 

func (v *ValidatorService) Keymanager() (keymanager.IKeymanager, error)

Keymanager returns the underlying keymanager in the validator

func (*ValidatorService) ProposerSettings 

func (v *ValidatorService) ProposerSettings() *validatorserviceconfig.ProposerSettings

ProposerSettings returns a deep copy of the underlying proposer settings in the validator

func (*ValidatorService) SetProposerSettings 

func (v *ValidatorService) SetProposerSettings(ctx context.Context, settings *validatorserviceconfig.ProposerSettings) error

SetProposerSettings sets the proposer settings on the validator service as well as the underlying validator

func (*ValidatorService) Start 

func (v *ValidatorService) Start()

Start the validator service. Launches the main go routine for the validator client.

func (*ValidatorService) Status
