Signing multiple transactions with BatchRequest

[eolszewski]

var batch = new web3.BatchRequest();
    await Promise.all(users.map(async user => {
        const signedTx = await web3.eth.accounts.signTransaction({
            chainId: "0x03",
            to: user.wallet,
            value: value * 1000000000000000000,
            gas: 2500000
        }, PRIVATE_KEY);
        batch.add(web3.eth.sendSignedTransaction.request(signedTx.rawTransaction,'receipt', console.log));
    }));
    batch.execute()

When executing this, I am getting replacement transaction underpriced.

The goal is to have one account send ETH to multiple accounts in a 'cohort transaction' within a system. The nonces are different, so I'm not sure why I'm getting the error stating that this is a replacement transaction...

I think you got to increase the nonce each time

[eolszewski]

@subramanianv web3 automatically increments the nonce here, this is seen when logging each signedTx as it is created.

I don't really know how batch works internally, but is there a possibility that it actually gets all the nonces at once. Then the first tx will pass, but not the others (if sent from the same address)?

[eolszewski]

This doesn't seem possible, I had to just loop through and put a delay between the sending of each signed transactions

@eolszewski Hi, did you ever get the batch working for sending multiple transactions? Right now I have working a script that makes individual tx and wanted to group them to save gas... But not getting many results. Thanks!

Hey @eolszewski @PeterTheOne @emiliomarin does using batch request work or providing a delay between each txn work? Please any help will be highly appreciated

I'm trying to sign multiple vouchers. User uploads an image and defines the quantity I need to create one signed voucher for each copy. For one voucher I manage to work using sendAsync the problem Is when I try to sign more than one. I tried to provide sendAsync to batch.add but I'm receiving an error since sendAsync and even send don't return a value. Any idea how I can handle it.
