Custom networks missing after reinstalling or restoring from Secret Recovery Phrase

When you reinstall MetaMask, custom networks need to be re-added. This is because MetaMask essentially considers your wallet to be a completely new instance of the app, and will not retain any of the data that was previously stored locally — custom networks being one example.

验证自定义网络信息

当网站要求您向 MetaMask 添加自定义网络时，您会看到 MetaMask 将用于与网络交互的信息。MetaMask 会对这些信息执行一些基本验证，若出现错误或异常，便会发出警告。MetaMask 还将防止多次添加同一个网络。然而，MetaMask 并不验证自定义网络，即使 MetaMask 的验证检查出来，该网络可能是恶意的或为请求该网络的网站所歪曲。
