Litecoin Core is the official free Litecoin wallet for PC. Therefore, as soon as you start using it on your computer, the PC itself will act as a wallet, and your private keys will be on it. It supports several operating systems, i.e. Windows, Mac and Linux.
Wallet synchronization takes some time, about 4 days, because Core-wallets are synchronized with the entire blockchain as with a full node. That is why the wallet requires not only time for synchronization, but also a lot of free space for storage.
We are pleased to release Litecoin Core 0.17.1. This is the new major version, which includes new features, various fixes and performance improvements, as well as updated translations. All users are advised to upgrade tothis version.
