When the wallet needs to be connected before using eth_chainId

[0xssw]

As I said, for example, nabox wallet needs to call eth_requestAccounts before using eth_chainId, When using the injected class, calling the connect function will use eth_chainId first, but nabox wallet needs to call eth_requestAccounts before using eth_chainId, which will make the user unable to connect to the wallet. Therefore, it is hoped that it can be changed to directly using provider.chainId instead of calling eth_chainId
