Metamask rpc error: execution reverted

Moralis General
#62

That looks fine as long as you’re using the USDT ABI, can you log the error from the useWeb3Contract hook to try and see what’s going on when you call approve.

useEffect(() => {
  console.log("error", error);
}, [error]);
#63

so sorry on my late reply… please here is the error message.main

#64

So this error happens and your MetaMask doesn’t get the transaction to sign? If so you may need to use ethers.js directly to set gas. You can try testing with another wallet.

#65

Thanks for replying, please can you direct me on how to use ether.js to set the gas?

#66

There is an example here. The approve transaction on that Ethereum contract goes to my MetaMask fine, I just don’t have enough ETH to pay for it. You can test with another wallet as well.

#67

Okay I’m about to try it with the example I saw there, thanks. I’ll update you on the outcome, thanks again.

#68 
const { runContractFunction: approve, data: enterTxResponse, error, isLoading, isFetching } = useWeb3Contract({

    // chain: "eth",

    contractAddress: "0xdAC17F958D2ee523a2206206994597C13D831ec7",

    abi: ABI,

    functionName: "approve",

    params: {

      _spender: "0xc.....",

      _value: 1,

    },

}

);

//gasprice

const gas = async () => {

const tx = await contract.approve(_spender, _value, [], {

  gasLimit: 100000,

  nonce: nonce || undefined,

});

};

const Web3Api = useMoralisWeb3Api();

const allowace = async () => {

  //Get token allowace on ETH

  const options = {

    //token holder

    _owner: user,

    //uniswap v3 router 2 contract address

    _spender: "0xc....",

    //ENS token contract address

    contractAddress: "0xdAC17F958D2ee523a2206206994597C13D831ec7",

  };

  const allowance = await Web3Api.token.getTokenAllowance(options);

  console.log(allowance);

};

please i still got the same error.

#69

You’re getting the same error from running the gas function now? Can you post the other code you’re using e.g. where gas is being called, your ethers.js code for the contract. Try setting a gasPrice and a higher gasLimit.

#70 
const gas = async () => {

  const ethers = Moralis.web3Library;

  const web3Provider = await Moralis.enableWeb3();

  const gasPrice = await web3Provider.getGasPrice();

  const signer = web3Provider.getSigner();

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

const transaction = await contract.approve({

  _spender: "0xc......",

  _value: 1,

  gasLimit: 10000000,

  gasPrice: gasPrice,

  // nonce: nonce || undefined,

});

await transaction.wait();

};

so sorry on the late reply

If same execution reverted due to gas, try increasing the gas price. You try add it manually
