What Is Crypto Cold Storage

Public Adress Public Key & Private Key

Youve probably heard these terms being thrown around with crypto when talking about cold and hot wallets, so lets get into their meaning:

Public Adress: This is what you send to other people who want to pay you with crypto.

Public Key: This is a long string of numbers generated by the private key, it is used by the wallet to make the public address.

Private Key: This is a long string of numbers that allows you to access your crypto whenever youd like.

In summary, the private key is an extremely long string of numbers used to derive the public key. The public key is also made up of a long string of numbers so it is compressed and shortened to form the public address. Thus, the public address is a hashed version of the public key, and the public key is a public version of the private key.

This is why you only need the private key backed up, everything is derived from it. Most devices will offer a seed phrase so that you dont need to remember the private key. But, again, make sure to keep this away from ANYONE. Dont share your seed phrase with anyone because it is the equivalent of your private key.

Although cold wallets are storage devices, the other purpose they serve is signing transactions.

This is similar to signing a check and giving it to a person!

Famous Hacks Involving Hot Wallets

As hot wallets are more dangerous to use compared with cold wallets, itâs unsurprising that theyâve become the subject of several notable hacks.

KuCoin fell victim to a major hacking attack in September 2020 â with criminals stealing funds from Bitcoin, Ether and ERC-20 hot wallets. It was initially thought that $150 million had been stolen, but it later emerged that this figure was closer to $280 million. Thankfully, âon-chain tracing, contract upgrades and judicial recoveryâ meant that at least 84% of these funds were later recovered.

In July 2019, cryptocurrency exchange Bitpoint â which is owned by the Japanese firm Remixpoint â also saw its hot wallet ransacked. The damage was estimated at $32 million, which is roughly a fifth of the assets that the platform had under management. Assets including Litecoin, Ether, Bitcoin and Ripple were taken. Tellingly, the companyâs cold wallets were not affected by this incident.

However, it is still possible that cold wallets can also be compromised â but not in the exact same way as hot wallets. Cold wallet provider Ledger suffered a hack in December 2020, but customer funds werenât stolen â customer information was. Over 272,000 Ledger customers had their names, mailing addresses and phone numbers leaked online by hackers, making them vulnerable to phishing attacks and other nefarious tactics to get at their cold storage crypto.

What Are Private Keys

Cold wallets also called hardware wallets are one of the best tools for safeguarding cryptocurrencies. This is because of the offline asset storage and also because ownership is physically in the owners hands making it very challenging for hackers to access. Cold stored cryptocurrency is not as susceptible to hacking, phishing, and other damage that leads to a loss of digital assets. Moreover, they are the ideal wallet for long-term storage.

What Is Crypto Cold Storage

Normal, online digital wallets, whether provided by a crypto exchange or a third party, all require internet access. That’s why they are typically called “hot wallets” by the community. Although they are safe enough, a lot of investors aren’t comfortable with keeping their crypto in third-party apps rather than keeping it in their own hands.

That’s where cold storage comes in. Cold storage simply means taking your cryptocurrency and transferring it into an offline storage vehicle. This most commonly refers to a hardware wallet, like the Ledger Nano X, in which users transfer their crypto onto the USB-based hardware wallet. Once stored there, you can put that hardware wallet wherever you want and access it later.

The benefit to crypto cold storage solutions is that they are impossible to hack. While someone could crack Coinbase one day, they can’t hack into a secure USB that’s not connected to the internet. However, there are disadvantages to hardware wallets as well. This includes the possibility of damage or simply losing them.

Cold storage is commonly used by cryptocurrencies exchanges. The idea is that storing this crypto in online wallets is very risky. As such, these companies transfer some of the crypto in cold storage, which cannot be accessed by anyone who is online.

The process of sending crypto to a cold storage is relatively easy. First, you need to set up two computers. One of the computer should have an internet connection. The other computer should have a bitcoin software installed. You should use a special software to generate a wallet.

Second, you need to get the master public key of the wallet and take it to the computer that is online. You should use this to create a watch-only wallet. You should then transfer the unsigned transactions to the offline computer to sign the transaction. Finally, you should send the fully-signed transaction to the online computer and send it to your network.

A cold storage is relatively safe. This is the main reason why many major exchanges have not been susceptible to hacks.

However, losing your physical cold wallet could result in complete loss of access to your private keys, and your funds. However, all is not lost, as most cold wallets such as the Ledger Nano X offer a mnemonic key phrase, which is a 12-word or 24-word security phrase which you can write down which can access your private keys.
