We need API keys for Polygon and Avalanche, otherwise calls are failing with {"status":"0","message":"NOTOK","result":"Max rate limit reached, please use API Key for higher rate limit"}
https://gasoracle.liquality.io/ does not return correct data, which can results in either slow transactions or malfunctioning transaction replacement:

Considerations:

We should consider using https://www.blocknative.com/ for Ethereum and Polygon. (it's paid)
We can also keep using https://github.com/rainbow-me/fee-suggestions for Ethereum, but it doesn't work well for Ropsten. It doesn't work at all for Polygon and Avalanche.
We should consider using https://gas-api.metaswap.codefi.network/networks/1/suggestedGasFees as I believe it's highly used by hundred of different projects for free.
