通过javascript（web3.js）从部署的智能合约中调用特定的solidity函数

Question

I try to call the transferMargin() function from the Synthetix Contract on Optimism Kovan through react/javascript(web3.js) and Metamask. I want to use on Button click the transferMargin function from the deployed smart contract but its not working iam not sure what is wrong with my code i have copied the full ABI from the contract and the address

This is my code:

import react, { useState } from "react";
import  { Component } from 'react';
import Web3 from 'web3'


export default function KwentaOptimism()
{

let provider = window.ethereum;
let selectedAccount;


if (typeof provider !== 'undefined') {  
    provider
    .request({method: 'eth_requestAccounts' })
    .then((accounts) => {
    selectedAccount = accounts[0];
    console.log(`Selected account is ${selectedAccount}`);
    })
                                                            }
                                                            
                                                            
const web3 = new Web3(provider);

async function getNetworkID(){
    const networkId = await web3.eth.net.getId();
    return networkId;

}

Answer 1

This is because you are trying to call the smart contract function using .call() when you should be using .send()

So you should try using

linkContract.methods.transferMargin("100000000000000000000").send();
    

Here you can read the documentation for each use case:
