Obviously because RPC is defined by INFURA_KEY while Infura does not support base yet.

It would be more reliable if RPC_URL could be supplied generally, instead of relying on a particular provider.

Checked the hardhat code. It's just missing in readme that for base one needs to define QUICKNODE_KEY . Using generic BASE_RPC_URL would still be best for more wider provider scope.
