No. Wallet has an RPC interface which you connect to your wallet with. It also has connections to p2p network. No use of FTP protocol anywhere I've seen in any coin.
I'm puzzled where you even got FTP from ? You could use FTP to download the wallet, or perhaps someone has the blockchain available via FTP, but that is all indirectly using FTP. People just use http to transfer files now and FTP is largely dead.
edit - I am seriously curious about the source of this query if you don't mind ?
