How to manually set gasLimit and gasPrice in ethers.js

Moralis General
#1

I have done everything that I can think of, use people’s examples online, tried Calculating it using the gas formular, but still got the same error.
Please here are my codes below, all I need is for someone to adjust my code to the correct form…
I’ve been in this issue for month and still haven’t gotten a solution, please.

main

#2 
const { runContractFunction: approve, data: enterTxResponse, error, isLoading, isFetching } = useWeb3Contract({

    // chain: "eth",

    contractAddress: "0xdAC17F958D2ee523a2206206994597C13D831ec7",

    abi: ABI,

    functionName: "approve",

    params: {

      _spender: "0xc....",

      _value: 1000000,

    },

},

);

// gasprice

const gas = async () => {
  const web3Provider = await Moralis.enableWeb3();

  const gasPrice = await web3Provider.getGasPrice();

  const signer = web3Provider.getSigner();

  const contract = new ethers.Contract("0xdAC17F958D2ee523a2206206994597C13D831ec7", ABI, signer);

const tx = await contract.approve({

  value: 1000000,

  gasPrice: gasPrice,

  gasLimit: 21000,

})

await tx.wait();

};

Look at a transaction on chain and try to understand what those 3 parameters mean. If you set them with random values it is not going to work.

#4

The gasLimit, I saw the figure on my metamask when trying to run a transaction, the value is the amount of usdt I want to send, the gasPrice can be change by the user.

This were the explanations I saw online.

That gasLimit, what does it mean? Where from did you get that number?
