Hello everyOne,
I need help to finish this function
I have a token, and I need to implement the burning function in my dapp.
Here is the source code, (BSC-Tesnet)

async function burn(){

let addressToken = “_____”;

const amount = document.getElementById(“amountBurn”).value;

const tx = {

from: accounts[0],

gas: Number(21000).toString(16),

gasPrice: Number(11000000000).toString(16),

data: contrato.methods.burn(web3.utils.toWei(amount.toString())).encodeABI(),

     }

web3.eth.sendTransaction(tx).then(res => {

  console.log("res",res)

}).catch(err => {

  console.log("err",err)

});

let result = await window.ethereum.request({method: “eth_sendTransaction”, tx}).catch((err)=>{console.log(err)});

}

What is the actual issue?

in this way the pop up appears, but the cost is too high, and warns that it will not work

async function burn(){

let addressToken = “_______________________________”;
const amount = document.getElementById(“cantidadQuema”).value; //textbox html

const tx = {
from: accounts[0],
data: contrato.methods.burn(web3.utils.toWei(amount.toString())).encodeABI(),
}
web3.eth.sendTransaction(tx).then(res => {
console.log(“res”,res)
}).catch(err => {
console.log(“err”,err)
});

let result = await window.ethereum.request({method: “eth_sendTransaction”, tx}).catch((err)=>{console.log(err)});

}

Is contrato.methods a typo

The contract definitely has a ‘burn’ function??

Seems very high cost but also you would expect to see the method in MM as ‘BURN’ and you only see ‘Contract interaction’

Contrato means contract in Italian…

“cantidadQuema” means amout to burn, its a HTML tag.
definitely has a ‘burn’ function? yes, and is public, its a burneable token. ERC20 Standar
