Paper Wallet

Definition

A paper wallet is a physical document containing a cryptocurrency's public address and private key, often as QR codes. It's a form of cold storage—completely offline and immune to online attacks. The paper itself becomes the bearer instrument.

Technical Explanation

Paper wallets are generated offline, ideally on air-gapped computers. The private key never touches an internet-connected device. To spend, users import the private key into a software wallet—but this "sweeps" all funds, as the key is now exposed.

Security concerns include: physical damage (fire, water), theft, printer memory retention, and the all-or-nothing spending model. Modern hardware wallets address many paper wallet limitations while maintaining cold storage benefits.

SynX Relevance

SynX supports paper wallet generation for long-term cold storage. Generate offline using trusted tools, store securely, and your quantum-resistant keys remain safe from all network threats—preserved on paper until you need them.

Frequently Asked Questions

Are paper wallets still recommended?
For extreme cold storage yes, but hardware wallets offer better usability for most users.
Can I spend partial amounts from a paper wallet?
Importing the key exposes it—sweep all funds and generate a new paper wallet for remainder.
How should I store paper wallets?
Fireproof safes, safety deposit boxes, or laminated copies in multiple secure locations.
