Variables

View Source
var ErrBadRequest = errors.Wrap(ErrNotOK, "recv 400 BadRequest response from API")

ErrBadRequest specifically means that a '400 - BAD REQUEST' response was received from the API.

View Source
var ErrNoContent = errors.New("recv 204 no content response from API, No header is available")

ErrNoContent specifically means that a '204 - No Content' response was received from the API. Typically, a 204 is a success but in this case for the Header API means No header is available

View Source
var ErrNotFound = errors.Wrap(ErrNotOK, "recv 404 NotFound response from API")

ErrNotFound specifically means that a '404 - NOT FOUND' response was received from the API.

View Source
var ErrNotOK = errors.New("did not receive 200 response from API")

ErrNotOK is used to indicate when an HTTP request to the Beacon Node API failed with any non-2xx response code. More specific errors may be returned, but an error in reaction to a non-2xx response will always wrap ErrNotOK.

	SubmitBlindedBlock(ctx context.Context, sb interfaces.ReadOnlySignedBeaconBlock) (interfaces.ExecutionData, error)
	Status(ctx context.Context) error
}

BuilderClient provides a collection of helper methods for calling Builder API endpoints.

type Checkpoint

type Checkpoint struct {
	*eth.Checkpoint
}

func (*Checkpoint) MarshalJSON

func (c *Checkpoint) MarshalJSON() ([]byte, error)

type Client

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

Client provides a collection of helper methods for calling Builder API endpoints.

func NewClient

func NewClient(host string, opts ...ClientOpt) (*Client, error)

NewClient constructs a new client with the provided options (ex WithTimeout). `host` is the base host + port used to construct request urls. This value can be a URL string, or NewClient will assume an http endpoint if just `host:port` is used.

func (*Client) GetHeader

func (c *Client) GetHeader(ctx context.Context, slot primitives.Slot, parentHash [32]byte, pubkey [48]byte) (SignedBid, error)

GetHeader is used by a proposing validator to request an execution payload header from the Builder node.

NodeURL returns a human-readable string representation of the beacon node base url.

func (*Client) RegisterValidator

func (c *Client) RegisterValidator(ctx context.Context, svr []*ethpb.SignedValidatorRegistrationV1) error

func (*Client) Status

func (c *Client) Status(ctx context.Context) error

Status asks the remote builder server for a health check. A response of 200 with an empty body is the success/healthy response, and an error response may have an error message. This method will return a nil value for error in the happy path, and an error with information about the server response body for a non-200 response.

func (*Client) SubmitBlindedBlock

SubmitBlindedBlock calls the builder API endpoint that binds the validator to the builder and submits the block. The response is the full execution payload used to create the blinded block.
