Your React component using wagmi to connect a wallet looks mostly correct, but there are a few adjustments to ensure everything works as intended. Specifically, you should use the configureChains and createClient functions from wagmi to properly set up the provider and client. Here’s the corrected and more complete example: import React from 'react';
import { WagmiConfig, createClient, configureChains } from 'wagmi';
import { mainnet, polygon, optimism, arbitrum } from 'wagmi/chains';
import { publicProvider } from 'wagmi/providers/public';
import { InjectedConnector } from 'wagmi/connectors/injected';
import { useConnect } from 'wagmi';
function App() {
// Configure chains and create client
const { chains, provider } = configureChains(
[mainnet, polygon, optimism, arbitrum],
[publicProvider()]
);
const client = createClient({
autoConnect: true,
connectors: [
new InjectedConnector({ chains }),
],
provider,
});
// useConnect hook to handle wallet connection
const { connect } = useConnect({
connector: new InjectedConnector(),
});
return (
<WagmiConfig client={client}>
<button onClick={() => connect()}>Connect Wallet</button>
</WagmiConfig>
);
}
export default App; |

The issue you're facing is related to the configuration of the wagmi library and the Ethereum provider. The error No provider configured for the chain mainnet indicates that wagmi doesn't have a provider configured for the Ethereum mainnet chain.
With these changes, your code should work correctly, and you should be able to connect your wallet using the "Connect Wallet" button. |
