Send USDT transaction error

Developer Discussion SDK

I want to send USDT transaction on Ethereum mainnet. But on the MetaMask, I got the error like this.
And the gas fee is so high.

And my code is like this:

let contractAddress = '0xdAC17F958D2ee523a2206206994597C13D831ec7';
let _amount = '0x' + Big(10).pow(6).times(amount).toNumber().toString(16)
contract = new web3.eth.Contract(abi, contractAddress);
data = await contract.methods.transfer(to, _amount).encodeABI();
ethereum
    .request({
        method: 'eth_sendTransaction',
        params: [{
            from: from, // The user's active address.
            to: contractAddress, 
            data: data,
            }],
    })
    .then((txHash) => {
        console.log(txHash)
    })
    .catch((error) => console.error(error));

The abi is like this I copy from Ethercan

[{
  "constant": false, 
  "inputs": [
      {
          "name": "_to", 
          "type": "address"
      }, 
      {
          "name": "_value", 
          "type": "uint256"
      }
  ], 
  "name": "transfer", 
  "outputs": [ ], 
  "payable": false, 
  "stateMutability": "nonpayable", 
  "type": "function"
}]

Anyone could tell me what is wrong. Thank you very much!

Hi where is it your code or are you using any contract sdk. I know the transactions were stopped to update dependencies not sure if it’s related could you try again later please

My enviroment is pure JavaScript.

And I import to js files in the code.

<script src="https://cdn.jsdelivr.net/gh/ethereum/web3.js/dist/web3.min.js"></script>
<script src="https://c0f4f41c-2f55-4863-921b-sdk-docs.github.io/cdn/metamask-sdk.js"></script>

And get Provider like this:

const web3 = new Web3(window.ethereum);
const MMSDK = new MetaMaskSDK.MetaMaskSDK()
await MMSDK.init();
const ethereum = MMSDK.getProvider() /

Thanks I’m not sure where you got this total formula I think it’s a bit off, have you tried on the testnet too before using mainnet do you see the same result?

Why does it add 1.38816… of ETH where this code is coming from:

Thanks for reply. The gas fee is calculated by MetaMask, might caused by an error in the contract. But I don’t know where is the error.
