ZEN has two types of wallets: full and light. The Swing wallet is a full wallet, while our Arizen and Horizen mobile wallets are light wallets.

The full wallet is capable of using z-addresses, which are also known as private addresses. The Swing Wallet needs to download the entire blockchain, but that will take a while and is going to use some space on your hard drive. It\'s available for macOS, Windows 7+ 64bit, and Linux.

The light wallets, on the other hand, don’t need the full blockchain but can only use and send to t-addresses. They can receive from z-addresses and t-addresses. Arizen is available on macOS, Windows, and Linux. The mobile wallet is only available on Android, but you can use Coinomi on iOS.
It\'s also possible to connect Arizen with a machine running zend (Swing without GUI) to use z-addresses in Arizen.

If you would rather use a web wallet, a paper wallet or want to find out more about the wallets, take a look here: https://horizen.global/wallets/
