Interact with Ethereum methods (e.g. getBalance)

[lidachao111222]

Hi, Lorenzo. Sorry for disturbing you.

I have one question about the Interact with Ethereum methods when I use the getBalance function with ether-swr. When I tried the minimal example. I saw that the ethereum amount won't change if I switch to another network(ex: from Ropsten to Rinkeby).

Would you like to give me some ideas please? Thank you.

I haven't tested the minimal example with network switch but I can imagine two things:

• It will updated after 30'' (refreshInterval) https://github.com/aboutlo/ether-swr/blob/master/examples/helloworld/src/App.tsx#L223
• You need to clear the SWR cache to make it happens immediately

import cache from 'swr' 
cache.clear()

Thanks for your reply.

The first idea that I tried before. It doesn't work.

I use the second idea like this: useEffect(() => { if (library !== undefined) { cache.clear() } }, [chainId]);

It also doesn't work.

Finally, I used another way to get balance and it works! lol
Here is the code:

```const { data: balance, mutate, error } = useEtherSWR(...``` // change different network if (error) { window.location.reload(); }

The page will reload if I change the network. Although I need to connect the wallet again.

Have a look at how it works https://github.com/NoahZinsmeister/web3-react. The problem you are facing seems more related to the web3 provider than ether-swr itself.
