EIP-1193 injected connectors mixes with wrong connector id's

[magiziz]

Describe the bug

Let's say i have my own connector metadata which includes id, name and provider.

Note: With metamask we'll use window.ethereum.providers, but with other connectors we would just use the normal window.ethereum provider

// Custom connector metadata "id" and "name"
export const customMetaDataConnectors = [
  {
    id: "metamask",
    name: "MetaMask Wallet",
    provider: window.ethereum.providers?.find(isMetaMask),
  },
  {
    id: "rainbow",
    name: "Rainbow Wallet",
    provider: window.ethereum,
  },
  {
    id: "enkrypt",
    name: "Enkrypt Wallet",
    provider: window.ethereum,
  },
  {
    id: "bitski",
    name: "Bitski Wallet",
    provider: window.ethereum,
  },
];

Once we set a metadata we create our own connectors and append them in createConfig:

import { http, createConfig, createConnector } from "wagmi";
import { mainnet, sepolia } from "wagmi/chains";
import { customMetaDataConnectors } from "./utils/createCustomConnector";
import { InjectedParameters } from "wagmi/connectors";
import { injected } from "wagmi/connectors";

export const createCustomConnector = (
  injectedParams: InjectedParameters,
  customMetaData: { id: string; name: string }
) => {
  return createConnector((config) => ({
    ...injected(injectedParams)(config),
    ...{ rkDetails: customMetaData },
  }));
};

export const config = createConfig({
  chains: [mainnet, sepolia],
  connectors: [
    ...customMetaDataConnectors.map((c) =>
      createCustomConnector(
        {
          target() {
            return {
              id: c.id,
              name: c.name,
              provider: c.provider,
            };
          },
        },
        { ...c }
      )
    ),
  ],
  multiInjectedProviderDiscovery: false,
  ssr: true,
  transports: {
    [mainnet.id]: http(),
    [sepolia.id]: http(),
  },
});

With window.ethereum when you disconnect your wallet and refresh it might pick up some random window.ethereum providers like bitski or enkrypt when it was never connected, but with metamask it works fine since we use window.ethereum.providers instead and try to find the right provider.

You can test that by using useAccount hook and get connector?.id which will display the current connected connector.

Link to Minimal Reproducible Example

https://wagmi-v2-injected-reproduction.vercel.app/

Steps To Reproduce

1. Have metamask wallet and rainbow wallet extension enabled and disconnect them both.
2. Connect to metamask and disconnect the wallet
3. Connect to rainbow and disconnect the wallet
4. Refresh the page and you'll see that the current connector id is not correct

I don't have bitski wallet and enkrypt wallet. Only rainbow and metamask.

[1997roylee]

I cannot run your demo, it throw "ProviderNotFoundError: Provider not found." on console.

[magiziz]

@1997roylee Pushed a change now. Can you try now ?

[1997roylee]

You should add checks for each provider. Pressing 'Disconnect Wallet' won't actually disconnect MetaMask; your wallet is still connected to the current site. the object "window.ethereum" is "alive".

[magiziz]

@1997roylee Yep that's correct MetaMask won't get disconnected since window.ethereum session is still alive. The problem becomes whenever i refresh the page i need some sort of way to see what connector.id is currently alive.

Right now if i have enkrypt, bitski and have disconnected metamask it'll still mark enkrypt as "connected" when i haven't interacted with that connector yet.

I know the logic right now is based on window.ethereum provider, but could be great to get the correct connector.id.

thats why we hv to implement a logic to validate window.ethereum is rainbow, is enkrypt, is bitski, otherwise we wont know what's wallet u are connecting.

@1997roylee Got it. This means i would have to create my own connector and check for is rainbow, is enkrypt, is bitski and etc ? Isn't that hard for maintenance to keep it up to date ?

Can't there be a check in wagmi by seeing if rainbow connector.id was connected to window.ethereum, if true connect the window.ethereum wallet and return rainbow as connector.id ?

@tmm Can you reopen this issue ? Seems like github actions closed it as "not planned"
