[METAMASK-EXTENSION] Add a custom network


#RC#

Understanding the underlying logic of a dApp can significantly reduce the time spent on debugging. When the network returns a failure signal, the first step is to verify the contract state. The metamask-extension interface may occasionally require a hard refresh to sync with the blockchain. Clearing the application’s local storage often fixes mysterious errors in the user interface.

Check if the transaction size exceeds the block’s maximum data limit before sending. Applying a patch requires a careful balance between speed and security in the crypto space. Advanced users can try simulating the call via a CLI tool to see the raw return data. While working with metamask-extension, it is important to monitor the official status dashboard.

Mismatching transaction parameters between chains is a common reason for failed swaps. Successfully fixing the is a great way to deepen your technical skills.
