[chybisov]

Is there an existing issue for this?

• I have searched the existing issues

Package Version

2.0.0-rc.0

Current Behavior

While testing the WalletConnect connector, I found an issue where if you need to switch chain it fails with this error

Uncaught (in promise) SwitchChainError: An error occurred when attempting to switch chain.

Details: {"code":-32602,"message":"Expected null or array with at least one valid string HTTPS URL 'blockExplorerUrl'. Received: [object Object]"}

Expected Behavior

The switch chain works as expected.

Steps To Reproduce

1. Connect wallet via WalletConnect
2. Select from and to chain and token (should be different from connected chain in the wallet)
3. Start swapping/bridging
4. Error will be thrown to the console and connected wallet with WalletConnect do nothing

Anything else?

I found that here https://github.com/wevm/wagmi/blob/rc/packages/connectors/src/walletConnect.ts#L266 we are trying to provide default block explorer URL, but actually providing object {name: 'BlockExplorer', url: 'Some URL'}
