It consists of a piece of paper with your private and public keys printed on it. An app might also create a scannable barcode for some paper wallets. It is a way to store and take access to your cryptocurrency offline.

A paper wallet is a physical document that contains a cryptocurrency's public address and private key. It serves as an offline method of storing digital assets securely, offering a tangible alternative to online or software-based wallets. The public address is where others can send cryptocurrencies to your wallet, while the private key allows you to access and manage the funds stored at that address.

Creating a paper wallet typically involves generating a pair of cryptographic keys using specialized software. The public address is then printed or written on the paper, visible to anyone for depositing funds. The private key, however, is kept hidden and is essential for accessing and transferring the cryptocurrencies stored at that address.

The key advantage of a paper wallet is its offline nature, which reduces the risk of hacking or unauthorized access associated with online wallets. Since it exists in physical form, it is immune to cyber threats such as malware or phishing attacks.

However, users must handle paper wallets with care, ensuring they are stored in a secure and dry place to prevent damage. Additionally, users should be cautious about creating paper wallets on compromised or insecure systems, as the security of the generated keys is crucial for the safety of the stored cryptocurrencies.
