I'm trying to generate address from xpub using this module @ont-community/hdkey-secp256r1 and later want to sign with privateKey generated from xpriv. But during the process, I noticed that the public keys generated from xpub and xpriv are not the same (this is not happen in cryptocoinjs/hdkey).

Here are my code to reproduce the problem:

const HDKey = require('@ont-community/hdkey-secp256r1');

// Please replace with your master private key
const xpriv = 'xprvxxxxx';

const hdkey = HDKey.fromExtendedKey(xpriv);
const newXpub = hdkey.publicExtendedKey;

const pubStr = hdkey.derive('m/0/0/176').publicKey.toString('hex');

const hdkey2 = HDKey.fromExtendedKey(newXpub);
const pubStr2 = hdkey2.derive('m/0/0/176').publicKey.toString('hex');

console.log(pubStr, pubStr2);

In file sdk/index.ts there is reference to ERROR_CODE.IllegalAddress which prevents building of sdk.

Why there's no documentation on how to use the lib?
Even a simple usage section would be appreciated

the reason is isBase64('12345678') returns true in transformPassword.

When attempting to run this package in NodeJS using NPM, requiring the module throws the following error:

ReferenceError: regeneratorRuntime is not defined

Steps to reproduce:

• Install via npm or yarn
• Create a empty JS file (eg. main.js)
• Require the package module (var Ont = require('ontology-ts-sdk');)
• Save and run from terminal (eg. node main.js)

Expected result:

• Script will execute successfully

Actual result:

• Console throws the error ReferenceError: regeneratorRuntime is not defined

This issue was not present about 6-8 months ago when I tried it last, so not sure what changed. Using node version 10.15.0

Hi, I found that the SDK using base-x for encoding/decoding, such as

However, the function encode(source) of base-x expects to receive the source as Buffer, not bytes array. Further more, in version 3.0.5, it will throw error if the parameter is not Buffer:
cryptocoinjs/base-x@6cbf08a#diff-168726dbe96b3ce427e7fedce31bb0bc

Please update the usage of encode using base-x.
Thank you.

Sorry to point this out, but I don't think we should convert amount to number in javascript since according to this stackoverflow: what is JavaScript's highest integer value that a number can go to without losing precision?, the actual amount to be transfered will not precise.

Here's my code to reproduce the problem:

const expectAmount = '90071992547409911';
const from = new Address('Some Address 1');
const to = new Address('Some Address 2');
const tx = makeTransferTx('ONG', from, to, expectAmount, '500', '30000');

const transferAmount = deserializeTransferTx(tx.serialize()).amount;
console.log('Expected Amount', expectAmount);   // Expected Amount 90071992547409911
console.log('Transfer Amount', transferAmount); // Transfer Amount 90071992547409900

What if I wanna use secp256k1 instead of the secp256r1 ? would it be possible?

Test network ask for payment to query DDO.
The transaction with tx obtained by buildGetDDOTx function return "Please input gasLimit >= 20000 and gasPrice >= 500" when sent.

There is a method to calculate fees in transaction.ts.
But it is deprecated. Is there any new method or alternative solution to calculate fee dynamically?

my code:

    let res
    const txid = "6b5bde081af77d6ba7e7e88d9d8655a6c5dcc68809b17e111f80b0c910a53ebd"

    console.log("----------rpc 查询交易id 解析----------")
    const rpcClient = new RpcClient('http://dappnode1.ont.io:20336');
    res = await rpcClient.getRawTransaction(txid)
    console.log(res)
    let txDetail = OntAssetTxBuilder.deserializeTransferTx(res.result);
    console.log(txDetail)

error happend in :

methodStr : "a147d9d8a8976cc416bb3b95b8af597886749b7cc84c86a14b3e5d59675dc1514c989893f32f55859b57e6805c86a0600eca43fca1ec86c51c1087472616e73666572"

tx.method : "¡GÙب�lÄ�»;�¸¯Yx�t�|ÈL�¡K>]Yg]ÁQL���ó/U��Wæ�\� `�ÊCü¡ì�Å���G&�ç6fW"

new ContractAddress(CONTRACT_ADDR) could be clearer than new Address(reverseHex(CONTRACT_ADDR))

How ONG actual fee is determined given gasPrice and gasLimit?

What I have to do create Wallet file/ WIF / Menmonic? Using which method? or which steps I've to follow?

Currently it returns {} as AbiFunction. and then reports xxx is not a function which is not clear.

Which is the code part that allows me to create a delegation tx? in order to stake my ONT.
Can you point me to it?

var tx = ontTxBuilder.makeTransferTx( tokenType, account.address, to, '1000000000', 300, 10000 );
const raw = account.signTransaction("123456",tx);

I know little about scrypt, did I pass the wrong parameters?

exactly what this error means?
That my address is not valid? even though it is on the chain?

How should I sign the transaction if I specify a different payer address than the sender address in the following code snippet?

const tx = OntAssetTxBuilder.makeTransferTx(assetType, from, to, amount, gasPrice, gasLimit, payer);
TransactionBuilder.signTransaction(tx, from_privateKey)

Do I need to sign the transaction twice, first with the sender's private key and then with the fee payer's private key?

const tx = OntAssetTxBuilder.makeTransferTx(assetType, from, to, amount, gasPrice, gasLimit, payer);
TransactionBuilder.signTransaction(tx, from_privateKey)
TransactionBuilder.signTransaction(tx, payer_privateKey)

In Result : 'Address...' has no balance enough to cover gas cost 10000000.

Here my from(admin) address has amount : 30
and I've passed Private key which is returned by Account object while generating address.
I am transferring amount: 1.

This error is occurs every time, with the message that transactor does not have balance enough to cover gas cost 10000000.

I'd suggest to split the sdk in multiple npm modules. So that's easier to mantain and reuse.

How to use addNotifyListener in websocketClient.ts ?
Seems not working.

I'm building a transaction, How to get transaction ID/Hash locally before any broadcast happen?
The Transaction hash that will be saved on the blockchain to be clear.

I tried getSignContent() but it's returning a different hash.

1. Compile step failed at below step and throw 'missing script build' error

npm run build

By inspecting package.json, it looks like it should be

npm run build:prod or npm run build:dev

package.json

"scripts": {
    "test": "jest",
    "build:dev": "webpack --display-error-details --config webpack.config.js --progress --color",
    "build:prod": "webpack --env.prod --config webpack.config.js --progress --color"
  }

And webpack installation is a prerequisite for this compile
npm install webpack --save

2. Test script npm run test isn't working , throwing error 'sh: jest: command not found'

Tried to build as per the instructions in Readme and got errors for missing dependencies. Using node 8.10.0. Installed these:

npm install utf-8-validate bufferutil

After that i got following error:

ERROR in ~/ontology-ts-sdk/src/index.ts(124,3)
          TS2304: Cannot find name 'Web'.

I see that Web was added in the most recent commit.

How to generate raw transaction and broadcast by using web api ?

Guess there's a bug here:

https://github.com/ontio/ontology-ts-sdk/blob/master/src/crypto/PrivateKey.ts#L285

sign method of ed25519 elliptic lib doesn't work like this:

        return Buffer.concat([
            signed.R.toArrayLike(Buffer, 'be', 32),
            signed.S.toArrayLike(Buffer, 'be', 32)
        ]).toString('hex');

Actually R and S doesn't exists. We have _R and _S, but toArrayLike fn is available only for _S.
For R we have the property _Rencoded that is an array.

Hello
I would like to get balance in testnet.
const newaddress = new Address("AXpNeebiUZZQxLff6czjpHZ3Tftj8go2TF");
console.log("newAddress: ", newaddress);
const nodeUrl = "http://polaris1.ont.io:20334"; // Testnet
const rest = new RestClient(nodeUrl);
console.log("rest: ", rest);
let balance = await rest.getBalance(newaddress);
console.log("balance: ", balance);
But the above error is occured.
How can I fix it?

Check code below:

If pass 40 bytes hex string into Address, then call toHexString(), you will get a reversed wrong hex address.

https://github.com/ontio/ontology-ts-sdk/blob/master/test/account.test.ts
Created address using above source. But the resultant address is not found on https://explorer.ont.io/testnet. Even after transferring some amount of ONG and Amount on it. Is there any solution?

Could you please update your build process?
Also, could you please deploy this package on npm repo?

Got stuck in this line:

  if (p2.y.cmp(this.y) !== 0) {
    throw new Error('Invalid y value for curve.');
  }

Is there something new on curve function ?

Here's my example:

const { GovernanceTxBuilder, TransactionBuilder, Crypto } = require('ontology-ts-sdk')
const { PrivateKey, Address } = Crypto

const seed = Buffer.from('05feadb3037d3afc7c878130a73b5b9e8fa6df42899dfaf874b4dfa8ab1bf4a4', 'hex')

const privateKey = new PrivateKey(seed, Crypto.KeyType.EDDSA, { curve: Crypto.CurveLabel.ED25519 })
// const privateKey = new PrivateKey(seed) // IT WORKS without EDDSA schema

//Sender's address
const address = new Address('APT4wZG9sFQfjhyfGALPXQj5UyrQ3ZCVkY')
// peers
const peerPubKeyList = ['039cadf7145731b3c868bd3528da9172757f89b566fc0372cd51b41351c3b6f237']
//Amount to stake
posList = [2]
//Gas price and gas limit are to compute the gas costs of the transaction.
const gasPrice = '2500'
const gasLimit = '20000'
//Payer's address to pay for the transaction gas
const tx = GovernanceTxBuilder.makeAuthorizeForPeerTx(address, peerPubKeyList, posList, address, gasPrice, gasLimit)

TransactionBuilder.signTransaction(tx, privateKey) // BUG with ed25519?

console.log('signed tx', tx)

// serialize tx ready to broadcast

const serialized = tx.serialize()
console.log('tx serialized', serialized)

I get this error when serializing the tx:

Hi there,

I am testing Claim function here, have signed a claim object and ready to interact with ontology chain to register the claim, a few questions here:

1. looks like we are missing a json schema section for RegisterClaim in /src/smartcontract/data/IdContract.abi.ts

2. also need a new helper function makeInvokeTransaction in /src/transaction/transactionBuilder.ts
   current makeInvokeTransaction is declaring tx.type=TxType.Invoke, which should be TxType.Claim for Claim Tx, assuming other parameters remain the same.

3. finally we need a new buildClaimTx helper function to construct the payload. Should it follow the same pattern as buildAddAttributeTx which takes 5 parameters to build?; Or 4 parameters without type, as described in identity_claim.md

'''var param = SDK.buildClaimTx(path, value, ontid, privateKey)'''

Happy to contribute by writing/testing them then submitting a pull request, if I know the required schema for RegisterClaim?

Thanks,
Bobio
