Air-Gapped Wallet FAQ
Q: Can I use my old smartphone as an air-gapped wallet?
A: Yes, but only if you permanently disable all radios (cellular/Wi-Fi/Bluetooth) and factory reset it offline. Dedicated hardware wallets are safer.
Q: How do I receive crypto without internet connection?
A: Your public address remains visible online for deposits. Only private keys for sending require air-gapped signing.
Q: Are paper wallets considered air-gapped?
A: Partially, but they lack transaction verification. Hardware wallets with screens provide superior security against address manipulation.
Q: What if my air-gapped device breaks?
A: Your steel-backed recovery phrase lets you restore funds on any compatible wallet – never store it digitally!
Q: How often should I check my air-gapped wallet?
A: Check balances monthly via blockchain explorers. Physically access the device only for transactions or updates (quarterly max).
