Currently, there isn’t a hardware wallet that supports Monero coins. Hardware wallets are very important for any cryptocurrency as they are the safest way to store them.
Both the Monero community and Ledger are working on a hardware wallet for Monero. There is supposed to be a hardware wallet release for Monero in 2018.
Note: Ledger is one of the most reputed and popular hardware wallet companies for Bitcoin, Ethereum and many other cryptocurrencies.
