The Ledger Nano S will be the hardware wallet supported by LGO Markets. This is necessary for a handful of reasons. First, the wallet will be necessary in order to authenticate your account upon creation. It will also be necessary in order to store your key in the 2-of-3 multi-signature wallet. This will ensure that no funds/assets are moved in or out of your account without permission, and will subsequently enable you to sign off on both the orders you place, as well as on withdrawal requests.
