Support for xDAI chain?

[adamazad]

I created a test bench for the library with xDAI:

import curve from '@curvefi/api';

(async () => {
  await curve.init(
    'JsonRpc',
    {
      url: 'https://rpc.xdaichain.com',
    },
    {
      chainId: 100,
    }
  );

  console.log(await curve.getBalances(['DAI', 'WBTC']));
  // // [ '1000.0', '0.0' ]
})();

Calling any method results in

E:\dxdao\curve-fi-bench\node_modules\@ethersproject\logger\src.ts\index.ts:225
        const error: any = new Error(message);
                           ^

}

My guess is that the library can't resolve the contract address for xDAI.

edit:

Seem like the case. The library points to mainnet's router 0xfA9a30350048B2BF66865ee20363067c66f67e58

Yeah. We will add xDAI later. There are only ethereum and polygon now

Done
