What's the standard way of adding chains?

[Oni-giri]

UseDapp provides a limited set of supported chains. However I can't seem to be able to configure it to work with alternative chains: is it a design choice or do I miss the "right" way of doing it?

Currently, the only way I see is to fork the repo and add manually the chain data in the constants folder.

Here is my (unfortunate) setup for arbitrum:

const config = {
  readOnlyChainId: 42220,
  supportedChains: [42220],
  multicallAddresses: {
    42220: '0xCe129333458f037867C81DFbD70E4D57A3b1c5eb',
}, 
  readOnlyUrls: {
    42161: 'https://arb-mainnet.g.alchemy.com/v2/API-KEY',
  },
}

While the DApp can connect to Metamask, it is unable to load the provider it appears as "undefined".

If there's no good way to do it, I guess adding support to manage it in the config should solve a good amount of issues, past, present and future.

Agree with you, having the same problem developing a dapp on Cronos testnet

@Oni-giri Yes I've found you can fake it to a degree using your own local version of ChainId that you extend, but it will ultimately fall over if the chain isn't in the core code. I suggest opening a PR like this one: https://github.com/EthWorks/useDApp/pull/336/files

Since the owner isn't replying, I forked the repo and uploaded it on NPM, so that I don't have to think about it any more.

hey @Oni-giri , did you get this to fix? I also forked and added arbitrum manually, but I'm getting message: "Internal JSON-RPC error."

You can either use https://www.npmjs.com/package/ethers-allstars-multicall, which is my fork of the package, or add those addresses, if you want to build it yourself:

I'm also trying to use a unsupported chain. whenever useContractFunction the react site crashes with an error of unsupported chain. is there any way around this?

[bashebr]

Does this support Fantom testnet? if not, can I add to list of chainId and supprted chains?

No it does not. You can add it.
