Cold storage refers to keeping cryptographic private keys on a device that is not connected to the internet, which eliminates the remote attack vectors that affect software wallets running in a browser or on a mobile phone. Ledger hardware wallets are the most widely adopted cold storage solution in the consumer crypto market. Customers who use Ledger tend to do so specifically because they want the security guarantee that their keys cannot be compromised through a phishing attack, a browser vulnerability, or a malware infection on their computer.
For merchants, accepting payments from Ledger users through 27 Blockchain's integration means serving a customer segment that holds crypto with a security-first approach. The Ledger wallet integration service handles the technical complexity of communicating with the hardware device during checkout so the security benefits of cold storage extend to the payment experience without creating friction for the customer or operational burden for the merchant.
