Nonce value is same when using two instance for two chains

[ujjwalguptaofficial]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

If i have two web3js instance with two different chains and i call getTransactionCount then value is being copied from first call.

const web3Parent = new Web3(new HDWalletProvider(privateKey, rpc.parent))
 const web3Child = new Web3(new HDWalletProvider(privateKey, rpc.child))



 const nonceChild = await web3Child.eth.getTransactionCount(from, 'pending');
  console.log('nonce', nonceChild); //11840

  const nonceParent = await web3Parent.eth.getTransactionCount(from, 'pending');
  console.log('nonce', nonceParent); // 11840

If i call getTransactionCount on parent first then value from parent will be returned in child.

Expected Behavior

value should be different on each chain.

i guess this is because of caching somewhere

Steps to Reproduce

 const web3Parent = new Web3(new HDWalletProvider(privateKey, rpc.parent))
  const web3Child = new Web3(new HDWalletProvider(privateKey, rpc.child))



  let nonce = await web3Child.eth.getTransactionCount(from, 'pending');
  console.log('nonce', nonce);

  nonce = await web3Parent.eth.getTransactionCount(from, 'pending');
  console.log('nonce', nonce);

@ujjwalguptaofficial Just wanted to let you know that I'm starting work on this now, apologies that it's been pending for so long

Thank you for bringing this to our attention, and thank you especially for taking the time to make a reproducible repo!

In my testing, this bug only seems to appear when both requests are sent with pending block tag e.g.:

web3.eth.getTransactionCount(from, 'pending');
web3.eth.getTransactionCount(from2, 'pending');

Yields duplicate count from first request

web3.eth.getTransactionCount(from, 'pending');
web3.eth.getTransactionCount(from2, 'latest'); // This could be anything besides 'pending', also order of calls doesn't matter

Yields correct respective counts

This seems to be an issue with Web3 being instantiated with multiple times with @truffle/hdwallet-provider

Instantiating two instance like so:

const web3Parent = new Web3(rpc.parent)
const web3Child = new Web3(rpc.child)

Yields the correct result

@ujjwalguptaofficial I can't provide you more information on this (can't seem to find an issue in Truffle repo for it, even though there's a comment about it), but it seems setting the option shareNonce to false will fix this issue:

const web3Parent = new Web3(new HDWalletProvider(
        privateKey,
        rpc.parent,
        0, // addressIndex
        1, // numberOfAddresses
        false //shareNonce
))
const web3Child = new Web3(new HDWalletProvider(privateKey, rpc.child))

For readability sake, this can be written as:

const web3Parent = new Web3(new HDWalletProvider({
        privateKeys: [privateKey],
        providerOrUrl: rpc.parent,
        shareNonce: false
}))
const web3Child = new Web3(new HDWalletProvider(privateKey, rpc.child))

Both of the above will result in the correct nonces being returned

I'm going to close this issue as it's not related to Web3.js

thanks @spacesailor24 :)
