Failure_wrong_network

Mansi1 · February 27, 2020, 1:13pm

Hello
Here is my code
Please suggest what else to add -

Thank you

CryptoBeliever · February 27, 2020, 1:43pm

I’m not sure what library are you using but it should be possible to log entire entity before signing (I guess transaction object). Also, please provide node where are you sending.

Hello
After running the chain of NEM coin when the chain url is hit with the makeTX() method , I dnt get the full transaction object . I get - nemtrnsObject

Please help me how will I get the full transaction Object.

Thank you

As it was already told (Failure_wrong_network) you are sending wrong network version.

What library are you using?
Please show transaction entity you are sending.

Mansi1 · March 13, 2020, 2:22pm

Hello
While running the chain I have used .nis library , are you asking about that one ? please tell .
Transaction entity I am sending through code is -
var transactionobject = {
‘isMultisig’: false,
‘recipient’: req.body.toAddress, // Dashes optional, all parsed later.
‘amount’: req.body.amount, // Amount of XEM to send.
‘message’: ‘Hello receiver!’, // Message to send.
‘due’: 60 ,// Not sure what this does but the default is probably fine.
‘version’: 1744830466,
“signer”: “my-publickey-is-here”
}
Please help and let me know if I am missing anything.
Thank you

Please show entire code because currently I don’s see how san object is defined. As I understand you are using this library -> https://www.npmjs.com/package/nem-api?

If you are using javascript I suggest use:

nem-sdk (https://github.com/QuantumMechanics/NEM-sdk) available with examples (https://github.com/QuantumMechanics/NEM-sdk/tree/master/examples)
or nem-library (https://nemproject.github.io/nem-library-docs/)

Hello
san is the variable which stores the ip and port of the server where Nem node chain runs.
Here is the image -

Thank you

CryptoBeliever · March 14, 2020, 4:02pm

Information from library you are using: https://github.com/nikhiljha/nem-api

So as I have written above, I suggest you to use nem-sdk.

Mansi1 · March 19, 2020, 7:24am

Hello @CryptoBeliever when I install nem-sdk npm I get mainnet url in the console for node - defaultMainnet: ‘http://hugealice3.nem.ninja’ ,the page shows " This page isn’t working" always .

Please help me to get api methods of nemCoin in nodejs.

CryptoBeliever · March 19, 2020, 7:57am

Because it’s not page but http API exposed by node. URL is correct and API works over 7890 port (for example http://hugealice3.nem.ninja:7890/chain/height).

API doc: https://nemproject.github.io/
nem-sdk examples: https://github.com/QuantumMechanics/NEM-sdk/tree/master/examples

Mansi1 · March 25, 2020, 1:02pm

Hello
I have tried by installing nem-sdk but it would be nice if you could show me an example of transfer with “https://nemproject.github.io/” link .
I have already shown you the transaction api which I made , please help and let me know where I have to use nem-sdk module.

Thank you

CryptoBeliever · March 25, 2020, 1:41pm

I’m not javascript developer.
Did you checked examples provided with nem-sdk https://github.com/QuantumMechanics/NEM-sdk/tree/master/examples ?

Mansi1 · March 26, 2020, 12:57pm

Hello
When I use nem-sdk for transfer for mainnet then I find in parameters to_address(receipient’s address) but I don’t find place to give sender’s address from where the amount will get deducted

CryptoBeliever · March 26, 2020, 5:44pm

Because you need use private key to sign transaction and not his address.

github.com

QuantumMechanics/NEM-sdk/blob/master/examples/browser/transfer/script.js

$(document).ready(function () {

	// Load nem-browser library
	var nem = require("nem-sdk").default;

    // Create an NIS endpoint object
	var endpoint = nem.model.objects.create("endpoint")(nem.model.nodes.defaultTestnet, nem.model.nodes.defaultPort);

	// Get an empty un-prepared transfer transaction object
	var transferTransaction = nem.model.objects.get("transferTransaction");

	// Get an empty common object to hold pass and key
	var common = nem.model.objects.get("common");

	// Set default amount in view. It is text input so we can handle dot and comma as decimal mark easily (need cleaning but provided by the library)
	$("#amount").val("0");

	/**
     * Function to update our fee in the view
     */

Hello @CryptoBeliever

Thanks a lot for helping me .
I have one more issue - that what is the amount cut as a transaction fee in nem transactions. Does the fee charge depends on the money being transferred?

Thank you

CryptoBeliever · April 11, 2020, 1:42pm

Yes. Fee calculation functions can be found here

github.com

QuantumMechanics/NEM-sdk/blob/cd532ca41403123ac1b919b94a7b568982428ec8/src/model/fees.js

import Helpers from '../utils/helpers';
import Format from '../utils/format';

/**
 * The Fee structure's base fee
 *
 * @type {number}
 */
const baseTransactionFee = 3;

/**
 * The Fee structure's Fee factor
 *
 * @type {number}
 */
const currentFeeFactor = 0.05;

Hello @CryptoBeliever
Right now whatever transactions I am doing , 0.1 fee is being deducted from the sender’s account

Mansi1 · April 11, 2020, 2:35pm

Hello

var common = nem.model.objects.create(“common”)("", req.body.privateKey);
var endpoint = nem.model.objects.create(“endpoint”)(“http://00.00.00.00”, 7890);
var transferTransaction = nem.model.objects.create(“transferTransaction”)
(req.body.to_address, req.body.amount, “Hello”);
var transactionEntity = nem.model.transactions.prepare(“transferTransaction”)
(common, transferTransaction, nem.model.network.data.mainnet.id)
nem.model.transactions.send(common, transactionEntity, endpoint)

I have used nem-sdk , and the fee always cut is 0.1

CryptoBeliever · April 11, 2020, 3:37pm

It depends what you including to transaction. What message and what mosaic amounts.

CryptoBeliever · April 11, 2020, 3:40pm

If short (up to 16 signs) message like “Hello” then additional 0.05 XEM is added to fee.
Without message it would be 0.05XEM
