I am wondering if it is currently possible to manually derive stake pool cold keys using a low-level module like cardano-addresses. The idea behind this is to have a single master seed/mnemonic, downstream of which all other key paths (staking, payment, node management, etc) lie. In other words, is
cardano-cli node key-gen currently the only command to create the cold keys, or is there another way?
CIP-1853 talks about such specifications, but I'm not sure if they are already implemented or if they can be manually implemented.
Thanks in advance!
