I see you are getting an error relationship to the web3 provider 'component. I'll help you fix it.
The Issue is that theweb3 provider ‘component expects aprovider' object to be passed as a prop, but in your code, you are tryping to access it directly from the contractabiand contract address.
Here's an updated version of your code with the necessary changes:
JSX
Import react, {useeffect, usestate} from "react";
Import {ethers} From 'Ethers';
Import {contract abi, contract address} from '../utils/contants';
Constereum = () => {
Const [accounts, set accounts] = usestate ([]);
useeffect (() => {
// Set the provider and get the accounts
Const provider = new ethers.providers.web3 provider (Window.etherum);
Const account list = Await provider.get signed accounts ();
Set accounts (account list);
// if there are no accounts found, try to connect to the ethereum Network Manually
if (accounts.length === 0) {
console.log ("no accounts were found.");
}
}, []);
Return (
Ethereum
{/ Your React app content here /}
);
};
Export default Ethereum;
In this updated version, I’ve added a usestate 'hook to store the list of accounts. When the Component Mounts, It Attempts to Connect to the Ethereum Network Using the Provider and Gets The Signed Accounts. If no accounts are found, it logs a message.
The Main Difference is that We're now passing theprovider ‘object as a prop to theethereum component, Instead of Trying to Access It Directly From theContractadress.
