We do not currently have our own wallet, preferring to focus our development on the Holo and Holochain software as there are already a number of suitable products available.
As HOT is an ERC-20 token any wallet which works with ERC-20 tokens can store HOT, though we always recommend using a hardware wallet, such as the Trezor or Ledger, for added security.
Note that you can find the Ledger support article on ERC-20 tokens here: https://support.ledger.com/hc/en-us/articles/115005197845-Manage-ERC20-tokens
And the Trezor article here: https://wiki.trezor.io/ERC20_tokens
