What is a paper wallet and how it works for crypto storage
What is a paper wallet?
A paper wallet is a method of storing cryptocurrency keys offline by printing the public key (used to receive funds) and private key (used to access and send funds) on a piece of paper. These keys are often displayed as QR codes for easy scanning.
Because the keys are kept offline, paper wallets are considered a form of cold storage, offering strong protection against online hacking attempts.
How it works
- Generate keys offline: Use a trusted tool to create a wallet while disconnected from the internet.
- Print the keys: Print your public (for receiving) and private (for sending) keys — often shown as QR codes for easy scanning.
- Store safely: Place the paper in a secure spot like a fireproof safe or safety deposit box.
- Use with caution: To access funds, you must import the private key into a software wallet — exposing it briefly to risk.
Why paper wallets matter in crypto
- Provide an inexpensive way to store crypto securely offline.
- Protect against malware, phishing, and exchange hacks.
- Useful for long-term holders ("HODLers") who rarely move funds.
- Can be created without trusting third-party custodians.
