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