Frequently Asked Questions
What is a hardware/cold wallet, and why do I need one?
A hardware wallet is a physical device that stores private keys offline. It helps protect your crypto assets from online threats such as hackers and malware, providing stronger long-term security compared to software wallets.
Why use a hardware wallet like Keystone?
If you hold crypto for the long term, or if your assets are valuable enough that you do not want to take risks, or if you often use DeFi, NFTs, multi-chain wallets, or other on-chain apps, a hardware wallet is a safer choice. Compared with mobile wallets, browser extensions, or exchange accounts, it better protects your private keys and helps reduce the risk of theft and attacks.
What's the difference between a hot wallet and a hardware/cold wallet?
A hot wallet, such as a software or online wallet, is connected to the internet and is more susceptible to hacking. In contrast, a hardware/cold wallet is offline when not in use, making it immune to online threats. Hardware/cold wallets are considered 'cold storage,' providing a higher level of security for long-term storage of cryptocurrencies.
Are hardware wallets safe?
Yes, hardware wallets are considered one of the most secure ways to protect your assets. The core advantage is that private keys are stored offline and never exposed to the internet. Transactions are also signed in an offline environment, which significantly reduces the risk of online attacks and malware.
And, security also depends on proper storage and safe usage practices. You should always purchase hardware wallets through official or authorized channels, securely store your recovery phrase (seed phrase) offline and never share or expose it to anyone, and carefully verify all transaction details before confirming any operation.

How do I use a hardware/cold wallet like Keystone?
A hardware wallet, also known as a cold wallet, is used to store crypto assets securely offline. You can usually set it up and use it as follows:
1. Buy a hardware wallet from the official website or an authorized reseller.
2. Download and install the official or supported mobile/desktop app.
3. Initialize the device and generate your seed phrase. Make sure to back it up securely offline.
4. Create a wallet address and use the device to sign transactions.

Can I recover my funds if I lose or damage my Keystone hardware/cold wallet?
Yes. As long as you have securely backed up your seed phrase, you can still restore and access your assets even if your device is lost, damaged, or no longer functional. You may recover your wallet on a new Keystone device or any wallet that supports the BIP39 standard by entering the original seed phrase generated by your previous Keystone wallet.
For additional backup protection, Keystone also offers the Keystone Tablet for more secure offline storage and management of recovery phrases. Always store your recovery phrase safely offline and never share it with anyone.

How does Keystone hardware/cold wallet differ from other hardware/cold wallets? Why is Keystone the best?
The Keystone hardware/cold wallet stands out due to its advanced security features, including 3 secure element chips, biometric authentication, and air-gapped (offline) transaction signing. The secure element enhances protection against physical attacks, while biometric authentication adds an extra layer of user verification. The air-gapped feature ensures that sensitive operations are conducted offline, reducing the risk of remote attacks.
Is Keystone compatible with a wide range of cryptocurrencies, and does it support future integrations via firmware updates?
Yes, the Keystone hardware/cold wallet currently supports a variety of cryptocurrencies, including BTC, ETH, XRP, SOL, ZEC, ADA, etc., and it is committed to continuous improvement. The Keystone team plans to expand its compatibility through firmware updates, ensuring users can access an even broader range of digital assets over time. Stay informed by checking for firmware updates on the official website to take advantage of the latest supported cryptocurrencies.
