Cloud-API DNS is automatically resolved to the instance closest to your application. For optimal performance, users can connect to endpoints by directly using an IP address from the table below.

We recommend to use gRPC for the best performance of Enterprise streaming endpoints, this feature is also with --grpc flag enabled. Additionally customers can use to run the subscription.

You can measure the latency from your gateway to the relays by pinging each relay IP from the machine hosting your gateway. For example, if you have a gateway set up in Virginia, USA, you can use the following command: ping 47.253.9.21.

Make sure to enable TLS when subscribing:

// this will use localhost CA to verify the certificate
creds := credentials.NewClientTLSFromCert(nil, "")
conn, err := grpc.Dial(url, grpc.WithTransportCredentials(creds))

Or using SDK:

creds := credentials.NewClientTLSFromCert(nil, "")

// create a config
config := &sdk.Config{
	AuthHeader: "<header>",
	GRPCGatewayURL: "virginia.eth.blxrbdn.com:5005",
	GRPCDialOptions: []grpc.DialOption{grpc.WithTransportCredentials(creds)}
}

// create a new client
c, err := sdk.NewClient(context.Background(), config)
