NONCE MANAGER IMPLEMENTATION

[itsmesoh]

Hi,

When i try to send multiple transactions one after the other, i get nonce errors where getTransactionCount is giving same values or sometimes even smaller values. for eg: if the current transaction count is 4 and i send three new transactions, i get values 5,5,2 repectively.

I read some discussions about the nonce manager but could not implement it in the correct way. Got errors such as "unknon address"..

Can anyone help with an example of how to use nonce manager correctly? The documentation available did not help much.

Thanks in advance.

Hi,

Would be possible to get ahold of any example code with usage of the nonce manager with sendTransaction together?

Below is a snippet from what i am working on. Could you please check and let me know if i am in the right path or far off from it.

import { NonceManager } from "@ethersproject/experimental";

const provider = new ethers.providers.JsonRpcProvider(
"http://goerli.prylabs.net"
);

const transactionCount = await provider.getTransactionCount(fromAddress);
const feeData = await provider.getFeeData();
console.log("Fee Data:", feeData);
const chainID = (await provider.getNetwork()).chainId ;
const tx = {
type: 2,
from: fromAddress,
to: toAddress,
value: ethers.utils.parseEther(5),
maxPriorityFeePerGas: feeData["maxPriorityFeePerGas"],
maxFeePerGas: feeData["maxFeePerGas"],
gasLimit: null,
chainId: chainID
};

const signer = provider.getSigner(tx.from);
const nonceManager = new NonceManager(signer);

const response = await nonceManager.sendTransaction(tx);

I get the below error when running this code at the sendTransaction method call:

processing response error (body="{"jsonrpc":"2.0","id":58,"error":{"code":-32000,"message":"unknown account"}}\n", error={"code":-32000}, requestBody="{"method":"eth_sendTransaction","params":

Thanks in advance.

You are using a public JSON-RPC provider, so you cannot access the account. You must use a Signer for which you have control of the private key. You cannot get an account simply by passing in the from address, if you have the private key you can use the Wallet class.

Thank you for the clarifications, Richard.

Will the Nonce Manager be moved into the core package of ethers any time soon?

[ricmoo]

It may be included as core in v6, but I’m not sure. But it may remain a separate package. Is there a reason you care whether it is core or an extension?

[itsmesoh]

Hi @ricmoo ,

Is nonceManager added in v6 ? the search did not show any result in the documentation.

[itsmesoh]

Will nonce manager have any effect after the introduction of "merge" proof of stake.

Thanks in advance . :)

[ricmoo]

No. It is independent of the merge.
