I want to automate the sell process of NFTs. It seems to me that the only backend wallet available right now is
cardano-wallet. To run
cardano-wallet I need to install
cardano-node. If you investigate about
cardano-node you always read about stake pools which seem to need 3 servers.
If I only want to use
cardano-wallet for the purpose mentioned above (no stake pool) do I need 3 servers too?
