Avoid site suggest gas fee - stick with Market about web3.js

Thanks @umbecanessa. The team will review this soon and get back with you.

similar issue here. The method mentioned by OP doesn't seem to let Metamask handle gas dynamically.

In my case the following example seems to set the correct gas fee, but Metamask shows the transaction as failed, even though the transaction was actually successful. So I'd prefer to just let Metamask handle gas completely.

      const gasEstimate = await erc20Contract.methods.approve(contractAddress, maxAllowance).estimateGas({ from: account });
      const gasPrice = await web3.eth.getGasPrice();

      const result = await erc20Contract.methods.approve(contractAddress, maxAllowance).send({
        from: account,
        gas: gasEstimate,
        gasPrice: gasPrice 

If we do this and then set "market" within Metamask gas settings, the transaction doesn't show as failed.

Hey there, this is something we definitely can fix. Will probably be added as a flag to allow metamask to make suggestions. What methods were u using?

Here's a very basic example:

import React from 'react';
import Web3 from 'web3';

const SimpleTransaction = () => {

    const sendTransaction = async () => {
        const web3 = new Web3(window.ethereum);
        await window.ethereum.request({ method: 'eth_requestAccounts' });
        const fromAccount = (await web3.eth.getAccounts())[0];

        const transactionParameters = {
            to: '0x.....',
            from: fromAccount,
            value: web3.utils.toWei('0.05', 'ether'),
            maxPriorityFeePerGas: undefined,
            maxFeePerGas: undefined
        };

        web3.eth.sendTransaction(transactionParameters);
    };

    return (
        <div className="flex flex-col items-center">
            <h1>Send Simple Transaction</h1>
            <button onClick={sendTransaction}>
                Send Transaction
            </button>
        </div>
    );
};

export default SimpleTransaction;

This is a snapshot of Metamask showing wrong gas fee instead of using "market" suggested gas:

ignoreGasPricing?: boolean;

can you use above?

[jdevcs]

use boolean flag to ignore gas price

@umbecanessa @Cam-B Hey there sorry this needs to be clearer in the docs, but you can use the ignoreGasPricing flag

const transaction = await web3.eth.sendTransaction(
        {
          from: accounts[0],
          to: 'address',
          value: '1',
          data: '0x01',
        },
        { bytes: ETH_DATA_FORMAT.bytes, number: ETH_DATA_FORMAT.number },
        { ignoreGasPricing: true }

We'll close this issue now, but let us know if there are any other issues and we'll open it again
