Patrick Iturra, Asset/Investment Manager & Consulting.


Security always takes top priority when navigating the complex world of digital currencies. For this reason, it has spurred the invention of numerous storage solutions for digital assets. Cold wallets have emerged as an attractive choice due to their secure nature. Therefore, this article will deeply dive into the intriguing history of crypto cold wallets, understand their essential functions, and, finally, explore some of the best in the market.

Unfolding the History of Crypto Cold Wallets

The evolution of crypto cold wallets is intimately intertwined with the history of Bitcoin. After Satoshi Nakamoto created Bitcoin in 2009, the first generation of digital wallets existed. At the outset, users stored their digital assets in ‘hot wallets,’ constantly connected to the internet and, thus, highly vulnerable to hacking.

In response to these security concerns, the company Trezor launched the first hardware wallet, a type of cold wallet, in 2014. This innovative product offered a secure offline “cold” storage solution as a physical device that safely stored the user’s private keys.

This invention marked a significant turning point in the history of crypto storage. Consequently, it inspired other companies like Ledger and KeepKey to develop their own models. Today, cold wallets have evolved beyond hardware devices to include paper wallets and metal wallets, all designed to maximize security.

Understanding the Functions of Crypto Cold Wallets

Crypto cold wallets provide a secure offline storage solution for cryptocurrency, preventing unauthorized access and cyber theft. They achieve this through several key functions:

1. Storing Private Keys: At the heart of a cold wallet’s function is the secure storage of the user’s private keys. Like a digital signature, the private key is crucial for authorizing cryptocurrency transactions. By storing this key offline, cold wallets ensure it is unreachable to online hackers.

2. Authorizing Transactions: In addition to storing cryptocurrencies, cold wallets are essential in authorizing transactions. When you want to send cryptocurrency, the cold wallet signs the transaction, after which you can broadcast it to the blockchain network.

3. Offering Backup and Recovery: Most cold wallets also provide a backup option, typically through a recovery phrase. You can use this phrase to restore the contents of your wallet in the unfortunate event you lose, damage, or have your device stolen.
