Paper Wallet
Web3 Infrastructure • Tools • Interfaces
physical offline key storage
A paper wallet is a physical printout or handwritten record that contains a cryptocurrency wallet’s public and private keys. It allows for completely offline storage, making it a form of cold wallet. While paper wallets are immune to online hacking, they must be stored securely to avoid physical damage or loss. Improper handling can lead to permanent loss of funds, so they are best used for long-term storage by experienced users.
Use Case: An investor generates a Bitcoin wallet offline, prints the public and private keys on paper, and stores the printout in a fireproof safe. This paper wallet holds long-term Bitcoin savings completely offline, immune to malware or online attacks—but vulnerable to physical theft or damage.
Key Concepts:
- Cold Wallet — Offline storage methods that include paper wallets and other disconnected solutions
- Private Keys — The critical information printed on paper that controls access to funds
- Hardware Wallet — More secure alternative for offline storage with easier access
- Physical Security — Paper wallets require protection from fire, water, theft, and deterioration
Summary: Paper wallets offer a low-tech, completely offline storage solution for cryptocurrency. While they provide strong protection against online threats, they require careful physical security and are generally recommended only for experienced users who understand the risks of permanent loss through damage or mishandling.
