Supported chains

[jasheal]

Really great work here on this lib. I'm refactoring an app to use this.

Currently I'm using useDapp and and I can pass in the supported chains. When a user tries to an unsupported network it provides an error and returns undefined for the account.

How would I achieve this or similar with wagmi?

Since you are able to just implement a custom provider and connector, you are free to use whatever RPC, etc you want. Have a look at the example code for a short intro into this topic: https://github.com/tmm/wagmi/blob/main/examples/next/src/pages/_app.tsx#L18-L46

Yes, in wagmi you define supported chains on a per connector-basic. InjectedConnector, WalletConnectConnector, etc. all have a chains property. For example,

const connectors = [
  WalletConnectConnector({
    chains: [chain.mainnet, chain.rinkeby],
    options: {
      ...
    },
  })
]

When someone connects to an unsupported network, you can use the useNetwork hook to identify that it is unsupported (data.unsupported) and show a prompt for switching the network.

Will consider adding unsupported somewhere to response of connector.connect as well.

@jasheal added unsupported to result of connector.connect so you'll know immediately if the chain is supported.

Awesome!
