Pag-verify ng custom na impormasyon ng network
When a website requests that you add a custom network to MetaMask, you are presented with the information MetaMask will use to interact with the network. MetaMask performs some basic validation of this information, and will warn you if anything seems wrong or unusual. MetaMask will also prevent the same network from being added more than once. However, MetaMask does not verify custom networks, and even if MetaMask's validation checks out, the network could be malicious or misrepresented by the website that requested it.
