I was generated 2 key pairs (public addresses and private keys) for 2 XLM addresses back in 2018 on Stellar Account Viewer. I only funded one of those public addresses with about 100 XLM. I did not fund the other public address as of today. When I look up the other public address which I did not fund the results come back as address not found, couldn't find or no results on any of the Stellar Explorers. Is that happening because it was never funded? I still have all the info provided to me from 2018.
