KeepKey

KeepKey is a hardware wallet that was launched in 2015 by Darin Stanchfield. It is a device that lets you store and manage your digital assets securely. It works together with software on your computer or phone, but securely holds your private keys and cryptocurrency offline on your secured KeepKey device. You can use it to send, receive, and exchange various cryptocurrencies, such as Bitcoin, Ethereum, Litecoin, and many more.
