func AdaptEth2HTTP

func AdaptEth2HTTP(eth2Svc *eth2http.Service, timeout time.Duration) Client

AdaptEth2HTTP returns a Client wrapping an eth2http service by adding experimental endpoints. Note that the returned client doesn't wrap errors, so they are unstructured without stacktraces.

func Instrument

func Instrument(clients ...Client) (Client, error)

Instrument returns a new multi instrumented client using the provided clients as backends.

func NewMultiHTTP

func NewMultiHTTP(ctx context.Context, timeout time.Duration, addresses ...string) (Client, error)

NewMultiHTTP returns a new instrumented multi eth2 http client.

func WithSyntheticDuties

func WithSyntheticDuties(cl Client, pubkeys []eth2p0.BLSPubKey) Client

WithSyntheticDuties wraps the provided client adding synthetic duties.
