Don't have a hard dependency on selectedAddress.

I don't believe selectedAddress isn't a standardized property on window.ethereum. While it may exist in MetaMask, there is no guarantee that it exists on any other wallet. Recommend having a fallback to the result of wallet_requestAccounts or eth_coinbase or eth_accounts. Currently, if the connect wallet doesn't have a selectedAddress property on window.ethereum the console gets spammed with Uncaught (in promise) TypeError: Cannot read property 'toLowerCase' of undefined because this function always returns undefined.
