Cold Wallet


Our process is simple

Private keys stored on a wallet connected to the internet are vulnerable to network-based theft. These wallets are known as hot wallets. With a hot wallet, all the functions required to complete a transaction are made from a single online device. The wallet generates and stores private keys; digitally signs transactions using private keys; and broadcasts the signed transaction to the network. The problem is that once the signed transactions have been broadcasted online, an attacker crawling the networks may become privy to the private key which was used to sign the transaction.

A Cold Wallet resolves this issue by signing the transaction with the private keys in an offline environment. Any transaction initiated online is temporarily transferred to an offline wallet kept on a device such as a USB, CD, hard drive, paper, or offline computer, where it is then digitally signed before it is transmitted to the online network. Because the private key does not come into contact with a server connected online during the signing process, even if an online hacker comes across the transaction, s/he would not be able to access the private key used for it. In exchange for this added security, the process of transferring to and from a cold storage device is somewhat more burdensome than the process for a hot wallet.

The most basic form of Cold Wallet is a paper wallet. A paper wallet is simply a document that has the public and private keys written on it. The document is printed from the bitcoin paper wallet tool online with an offline printer. The paper wallet or document usually has a QR code embedded on it so that it can easily be scanned and signed to make a transaction. The drawback to this medium is that if the paper is lost, rendered illegible or destroyed, the user will never be able to access his address where his funds are.

Another form of cold storage is a hardware wallet which uses an offline device or smartcard to generate private keys offline. The Ledger USB Wallet is an example of a hardware wallet that uses a smartcard to secure private keys. The device looks and functions like a USB, and a computer and Chrome-based app are required to store the private keys offline. Like a paper wallet, it is essential to store this USB device and smartcard in a safe place, as any damage or loss could terminate access to the user’s bitcoins. Two other popular hardware wallets include TREZOR and KeepKey.

Finally, users looking for cold storage options can also opt for offline software wallets, which are quite similar to hardware wallets but are a more complex process for less technical users. An offline software wallet splits a wallet into two accessible platforms – an offline wallet which contains the private keys and an online wallet which has the public keys stored. The online wallet generates new unsigned transactions and sends the address of the user to the receiver or sender on the other end of the transaction. The unsigned transaction is moved to the offline wallet and signed with the private key. The signed transaction is then moved back to the online wallet which broadcasts it to the network. Because the offline wallet never gets connected to the internet, its stored private keys remain secure. Electrum and Armory are often quoted as the best offline software wallets in the crypto economy.

Cryptocurrency users should ensure that the wallet of their choice is compatible with the coins they transact or trade in, as not all wallets support all cryptocurrencies.
