Support for Darwinia Network

As an enthusiastic supporter of Darwinia Network, which is compatible with EVM technology, I aim to create an intuitive staking dashboard to educate users about staking details. Ideally, incorporating integration with Dune would greatly enhance functionality and user experience!
