Paper Wallet
Web3 / wallets security
A paper wallet is an offline storage method for cryptocurrency created by printing or writing a wallet's public address and private key onto a physical piece of paper. This completely disconnects the private key from internet-connected devices, making it immune to online hacking, malware, and exchange breaches. To use funds from a paper wallet, the private key must be manually entered or scanned back into a software wallet, at which point the cryptocurrency can be transferred. Paper wallets offer strong security for long-term storage but require careful physical safeguarding and can be inconvenient for frequent transactions.
Example
Many Bitcoin holders during the 2010s generated paper wallets using tools like BitAddress.org, printing them in secure locations and storing them in safes or safe deposit boxes as a cold-storage backup strategy.
Why It Matters
Paper wallets represent a foundational cold-storage strategy that eliminates digital attack vectors, making them a critical option for users prioritizing maximum security and long-term asset preservation over convenience.
