Avalanche Mainnet/Fuji Infura support

[charlie-kim]

Describe the Feature

Similar to #3323, creating a InfuraProvider instance with chain ID 43114(mainnet), 43113(fuji testnet) generates unsupported network error.

{
  reason: 'unsupported network',
  code: 'INVALID_ARGUMENT',
  argument: 'network',
  value: { chainId: 43114, name: 'unknown' }
}

Code Example

new ethers.providers.InfuraProvider(43114, {
  projectId: infuraProjectId,
  projectSecret: infuraProjectSecret,
})

This is still WIP. Any estimated time for it to be completed?

@charlie-kim @woosal1337 To bypass the 'unsupported network' error with Avalanche networks, switch to using ethers.JsonRpcProvider with your network's RPC URL.

Is Avalanche json-rpc compatible with Ethereum?

For some reason I thought it wasn’t. But if it is, I can add it to the InfuraProvider.

@ricmoo Looks like only C-Chain is compatible.

Thanks. But ethers.JsonRpcProvider makes extra request to get chain ID. It will be better to use ethers. InfuraProvider.
