How to interact with no read-only smart contracts through a website

#1

Hellow,
I would like to know if there are any way to call a function from a ethereum smart contract that isnt read-only with javascript. I only have found Moralis.EvmApi.utils.runContractFunction, but Im getting this error:
Moralis SDK Core Error: [C0006] Request failed, (400): Function mint is not read only
Thank you

for write functions you can use web3 or ethers library with currently connected wallet that can be metamask for example

#3

How can i “link” the metamask account with which I autheticated to web3? I m currently logging in with this tutorial: https://docs.moralis.io/authentication-api/how-to-sign-in-with-metamask

#4

there is this code here:

import { MetaMaskConnector } from "wagmi/connectors/metaMask";
import { useAccount, useConnect, useSignMessage, useDisconnect } from "wagmi";
import { useAuthRequestChallengeEvm } from "@moralisweb3/next";

function SignIn() {
  const { connectAsync } = useConnect();
  const { disconnectAsync } = useDisconnect();
  const { isConnected } = useAccount();
  const { signMessageAsync } = useSignMessage();
  const { requestChallengeAsync } = useAuthRequestChallengeEvm();

  const handleAuth = async () => {
    if (isConnected) {
      await disconnectAsync();
    }

    const { account, chain } = await connectAsync({
      connector: new MetaMaskConnector(),
    });

    const { message } = await requestChallengeAsync({
      address: account,
      chainId: chain.id,
    });

    const signature = await signMessageAsync({ message });

    console.log(signature);
  };

  return (
    <div>
      <h3>Web3 Authentication</h3>
      <button onClick={handleAuth}>Authenticate via Metamask</button>
    </div>
  );
}

export default SignIn;

that is used to sign a message with current wallet application

maybe the documentation for wagmi can help you
