[Air Gap Wallet] (https://supraoracles.com/academy/what-is-an-air-gapped-wallet/) are crypto wallets that are completely disconnected from the internet and any form of physical wireless communication, which can effectively enhance security.

**This tutorial will teach you how to create an air-gapped wallet and initiate offline transactions. **
