In light of the recent [XCH theft] (https://chiaforum.com/t/attention-coins-disappear-from-wallets/18854/129), many friends are very concerned about how to keep their assets safe. Here, I would like to recommend you to create an Air-gap (offline) wallet using a mint wallet.
What is an Air-gapped?
[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.
[Mint Wallet] (https://info.pawket.app/) is the first air-gapped wallet in the Chia ecosystem. With Mint Wallet, you can create an offline and secure air-gapped wallet. You can also use it to sign transactions offline (with an online device) and enjoy the same convenience as an online wallet.
**This tutorial will teach you how to create an air-gapped wallet and initiate offline transactions. **
How to create an air gapped wallet using Mint wallet
Reset an Android phone and set WiFi/Bluetooth/GPS to disabled.
Using USB, upload the [pawket.apk] (https://github.com/SutuLabs/pawket-android/tags) file to your phone and install it. (No internet connection required)
- Follow the prompts to complete the wallet creation. This is an Air-gappde wallet created completely offline. (hereinafter referred to as AGP).
How to initiate a transaction using an air-gapped wallet
- After creating an account with AGP, share the account public key* with your online mint wallet (hereinafter referred to as ONP).
- *: Get the public key of the account, click "Scan" → "Public Key QR Code" on the login screen.
- After adding the AGP's public key to the ONP, you can view the balance, using almost all online functions such as "send XCH/CAT, create/accept offers, send in bulk, issue CAT, issue NFT", etc.
- However, since only the public key is added to ONP, only the observer wallet can be viewed.
- Now you can initiate a transaction using ONP and you will find that it generated a QR code.
- At this point, scan this QR code using AGP.
- Then use ONP to scan the QR code on the AGP (that is, the signature information on the AGP).
- Submission successful!
Summary
- Create Mint Wallet - Air Gap Wallet (AGP) offline.
- Add a public key account on the online mint wallet (ONP).
- Scan the QR code signature on the ONP using AGP.
- Then scan the QR code containing the signature information on the AGP with ONP.
- Finally, the signature is put into a spend bundle with ONP and sent to the blockchain.
**Using an air-gapped wallet not only ensures security but also provides flexibility. **
**I hope everyone can protect their assets as much as possible! **
