A hot wallet is essentially a type of digital cryptocurrency wallet that is connected to the internet. Unlike a ‘cold wallet’ that operates offline, a hot wallet is always ‘active’ and available to the user, facilitating quick access to your digital funds. Imagine a cold wallet as your everyday physical wallet: you carry it with you, you have quick access to money for shopping, but because it is always exposed, there is a higher risk of losing it or having it stolen. In the digital world, this “exposure” means internet connectivity.
How does a hot wallet work?
Hot wallets store the private keys to your cryptocurrency. These keys are essential because they give you control over your funds. The fact that the wallet is online allows almost instant access to these keys to sign and transmit transactions to the blockchain network.
Common types of hot wallets
- Web Wallets: these are wallets hosted by an online service (e.g. a cryptocurrency exchange). Access is via a web browser. They are extremely convenient for quick trading, but security is highly dependent on the security measures of the platform in question.
- Mobile Wallets: Apps installed on your smartphone. Very handy for quick payments or checking your balance on the go.
- Desktop Wallets: Software installed directly on your personal computer. Offers greater control over private keys than web wallets, but security depends on the security of your operating system and anti-virus measures.
Benefits
- Convenience and accessibility: You can send and receive cryptocurrency anytime, anywhere, as long as you have an internet connection.
- Speed: Transactions are processed quickly, ideal for day-to-day trading or payments.
- Ease of use: Most hot wallets have intuitive interfaces and are easy to set up.
Disadvantages and risks
The main disadvantage of hot wallets is the security risk. Because they are connected to the internet, they are more vulnerable to:
- Cyber attacks: hacking, phishing, malware or viruses can compromise the security of your private keys.
- Platform vulnerabilities: In the case of web wallets, if the platform that hosts them is attacked, your funds may be at risk.
- Human error: Lost passwords or recovery passphrases can lead to permanent loss of access to funds.
When to use a hot wallet?
Hot wallets are great for small amounts of cryptocurrency, frequent transactions or quick access to funds. Think of them as your “living expenses” wallet. For larger amounts or long-term storage, cold wallets are recommended, as they offer a much higher level of security.
