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.
