MetaMask Won't Connect? Web3 Wallet Troubleshooting Guide

Where Is My Web3 Wallet?

Have you ever opened your browser wallet (like MetaMask, Trust Wallet, or Coinbase Wallet) to connect to a dApp, only to find:

• Incorrect balances or addresses displayed?
• Your wallet completely missing from the connection options?

These issues are common among desktop users of Ethereum-based wallets (including Polygon, BNB Chain, Arbitrum, and other EVM-compatible networks). Below, we’ll diagnose the root causes and provide actionable solutions.

1. Disabled Browser Extension

Problem: Your wallet extension might be turned off.
Solution:

1. Navigate to your browser’s extension settings (e.g., chrome://extensions/ in Chrome).
2. Ensure the toggle next to your wallet (e.g., MetaMask) is enabled (blue).
3. Reload the dApp page to reconnect.

2. Multiple Wallets Causing Conflicts

Problem: Having multiple wallets installed can lead to injection conflicts in the window.ethereum space.
Solution:

1. Disable all other wallet extensions via chrome://extensions/.
2. Set your preferred wallet as the default (check its settings).

3. Refresh the page and inspect window.ethereum in the browser console:

   • If another wallet appears, disable it and retry.

Pro Tip: Some wallets (e.g., Binance Chain Wallet) use alternative injection spaces like window.binance.

3. Brave Browser’s Built-in Wallet

Problem: Brave’s native wallet overrides extensions.
Solution:

1. Go to Preferences → Web3.
2. Set Default Ethereum wallet to "Brave Wallet (Prefer extensions)".

4. Outdated Browser or Extension

Problem: Older versions may lack compatibility fixes.
Solution:

1. Update your browser (Chrome/Firefox/Brave).
2. Update MetaMask via the Chrome Web Store or its official site.
