UTXO functionality about avalanchejs HOT 21 CLOSED

Glad to hear that you're getting the proper UTXO data. Try signing your tx like this:

let unsignedTx = await xchain.buildBaseTx(utxos.utxos, sendAmount, assetid, [friendsAddress], addresscheck, addresscheck);
let tx = unsignedTx.sign(xchain.keyChain());

from avalanchejs.

I don't think this is a getUTXOs problem, but you're not connecting to the node itself. @cgcardona can you reach out and assist?

from avalanchejs.

const avalanche = require("avalanchejs");
let myNetworkID = 5; //default is 3, we want to override that for our local network
let myBlockchainID = "X"; // The X-Chain blockchainID on this network
let ava = new avalanche.Avalanche("localhost", 9650, "http", myNetworkID, myBlockchainID);
let xchain = ava.XChain();

let addresscheck = ['X-fuji1gkw5z7qw0fn49xn875uyfd9hhcw9fctddvkdru']
getUTXOs(addresscheck);

async function getUTXOs(addresscheck)
{

let utxos = await xchain.getUTXOs(addresscheck);
console.log("Checking utxos: ", utxos);
let sendAmount = new avalanche.BN(100);

let assetid = "U8iRqJoiJm8xZHAacmvYyZVwqQx6uDNtQeP3CQ6fcgQk3JqnK"; //avaSerialized string
let friendsAddress = "X-fuji1acx2e6drpwkyuy5dtfqxt65vygtxd4xse60lwk";
let unsignedTx = await xchain.buildBaseTx(utxos, sendAmount, [friendsAddress], addresscheck, addresscheck, assetid);

}
It is giving me this error:

@collincusce I have connected to node but it is giving me above error.

from avalanchejs.

I'm looking in to this today. I'll keep you posted on what I find @AnasSaeed123. Thanks.

from avalanchejs.

@AnasSaeed123 the syntax has changed recently. I'll make sure to get the docs updated. Can you try this script? It works for me.

import { Avalanche} from "avalanche"
let myNetworkID = 5; 
let myBlockchainID = "X"; 
const avalanche: Avalanche = new Avalanche("localhost", 9650, "http", myNetworkID, myBlockchainID)
let xchain = avalanche.XChain();

let addresscheck = ['X-fuji1gkw5z7qw0fn49xn875uyfd9hhcw9fctddvkdru']
getUTXOs(addresscheck);

async function getUTXOs(addresscheck: string[])
{
  let u = await xchain.getUTXOs(addresscheck);
  let utxos = u.utxos;
  console.log("Checking utxos: ", utxos);
  let sendAmount = new BN(100);

  let assetid = "U8iRqJoiJm8xZHAacmvYyZVwqQx6uDNtQeP3CQ6fcgQk3JqnK"; //avaSerialized string
  let friendsAddress = "X-fuji1acx2e6drpwkyuy5dtfqxt65vygtxd4xse60lwk";
  let unsignedTx = await xchain.buildBaseTx(utxos, sendAmount, assetid, [friendsAddress], addresscheck, addresscheck);
}

from avalanchejs.

Okay I'll try it and keep you updated.

from avalanchejs.

@cgcardona Can it work for this code also: "const avalanche: Avalanche = new Avalanche("api.avax-test.network", 443, "https", myNetworkID, myBlockchainID)" . Guide me in this case also.

from avalanchejs.

@cgcardona This API is giving me desired data of utxos. Also unsignedTx is done using above API but it is giving me this error when signing the transaction:

I am followiing this code because localhost is not working for me correctly: "
const avalanche = require("avalanchejs");

let myBlockchainID = "X"; // The X-Chain blockchainID on this network

let xchain = ava.XChain();

let addresscheck = ['X-fuji1acx2e6drpwkyuy5dtfqxt65vygtxd4xse60lwk']
getUTXOs(addresscheck);

async function getUTXOs(addresscheck)

let utxos = await xchain.getUTXOs(addresscheck);

console.log("Checking data: ", utxos.utxos);

//console.log("Checking data: ", unsignedTx.transaction);
let signedTx = xchain.signTx(unsignedTx);
}

from avalanchejs.

Glad to hear that you're getting the proper UTXO data. Try signing your tx like this:

let unsignedTx = await xchain.buildBaseTx(utxos.utxos, sendAmount, assetid, [friendsAddress], addresscheck, addresscheck);
let tx = unsignedTx.sign(xchain.keyChain());

Not getting the desired result by using above code.

from avalanchejs.

After taking sha256 of serialized transaction data I have generated signature in C language(Because I am integrating Avalanche in OPOLO Cosmos Hardware wallet in C language) . After that I followed documentation : "https://docs.avax.network/v1.0/en/references/avm-transaction-serialization/#what-signed-transaction-contains" I concatenated unsignedTx and credentials. Is there any API which can issueTx in hex form.

from avalanchejs.

{
"jsonrpc": "2.0",
"error": {
"code": -32000,
"message": "problem decoding transaction: invalid input checksum",
"data": null
},
"id": 15
}

Giving this error when sending transcation.

You can call avm.issueTx and have the 2nd optional parameter be encoding. More info

curl -X POST --data '{
    "jsonrpc":"2.0",
    "id"     : 1,
    "method" :"avm.issueTx",
    "params" :{
        "tx":"6sTENqXfk3gahxkJbEPsmX9eJTEFZRSRw83cRJqoHWBiaeAhVbz9QV4i6SLd6Dek4eLsojeR8FbT3arFtsGz9ycpHFaWHLX69edJPEmj2tPApsEqsFd7wDVp7fFxkG6HmySR",
        "encoding": "hex"
    }
}' -H 'content-type:application/json;' 127.0.0.1:9650/ext/bc/X

Does that work for you?

Having problem in signing transaction. Please guide me in this matter.

Has this been resolved or have you made progress?

Have you looked at the examples to see if there's any hints what's going on?

hopefully you can find what you are lookig for by going through the tests for tx and utxos below.
