+!!! warning "Troubleshooting stuck transactions with MetaMask"
+    If you encounter a stuck transaction, it is likely due to an incorrect nonce setting. 
+

+
+      1. Open Metamask and navigate to your account.
+      2. Click on **Settings**.
+      3. In the **Settings** menu, select **Advanced**.
+      4. Locate the option **Clear activity and nonce data** and click on it.
+      5. This resets the nonce data associated with the account, which often resolves transaction-related issues.
