var RPC_ADDRS = []string{
	"wss://testnet-rpc0.cess.cloud/ws/",
	"wss://testnet-rpc1.cess.cloud/ws/",
	"wss://testnet-rpc2.cess.cloud/ws/",
}

func main() {
	sdk, err := cess.New(
		context.Background(),
		// Set sdk name
		cess.Name("my-sdk"),
		cess.ConnectRpcAddrs(RPC_ADDRS),
	)
	if err != nil {
		panic(err)
	}
