This is a simple PR that add icons to Moonbeam, Moonriver and Moonbase Alpha.

All icons were uploaded to IPFS:

Hey, I checked the CI and saw the following:

Exception in thread "main" org.ethereum.lists.chains.model.CantReachExplorerException: explorer https://moonbeam.moonscan.io/ does not return 2XX but 403

This is because it is probably bumping into Cloudflare verification.

what do you suggest?

what do you suggest?

There is very little we can do because that is Cloudflare protection. You get 403 with https://etherscan.io

CI failing -> no merge
also wonder why it is not a problem for other explorers

[albertov19]

@ligi, that is unfortunate. I ran the CI against _data/chains/eip155-1.json (Ethereum file), which runs into the same issue.

Etherscan moved to Cloudflare, so the CI will probably fail for most Cloudflare-protected Blockexplorer pages.
