What is a Hot Wallet?
A hot wallet refers to a virtual currency wallet that is accessible online, and it facilitates cryptocurrency transactions between the owner and end-users. A collection of private keys stored on a program connected to the internet is used to store and send different currencies such as Bitcoin. By storing and securing holdings, digital wallets for cryptocurrency provide accessibility and convenience of financial transactions within a virtual currency economy.
A hot wallet is also known as a hot wallet service, and it is one of the two types of cryptocurrency wallets. A cryptocurrency wallet can be categorized into a hot wallet and a cold wallet. The difference between the two is that the former requires an internet connection while the latter does not require one.
Key Highlights
- A hot wallet is an online vault that can work on different blockchains and allows the exchange of different currencies between the owner and end users.
- One of the major challenges facing a hot wallet is the security breaches of private keys which are stored on the internet and in the wallet’s browser.
- Users of hot wallets should keep a small portion of cryptocurrency funds on such platforms to discourage cybersecurity threats.
Understanding Hot Wallets
Such unconventional currency systems enable higher anonymity, optimal protection of user privacy, and flexibility of financial transactions. However, the same inherent properties present challenges to services and systems that strive to curb fraudulent activities and other exploits. As a result, investors may choose to connect their cryptocurrency funds to the internet or to operate offline. The practice will still allow secure exchange of currencies between cryptocurrency owners and end-users.
Holders tend to keep multiple digital wallets for cryptocurrency, including both hot wallets and cold wallets, mainly for security reasons. The functionalities of a hot wallet can facilitate safe transactions between users who hold small amounts of cryptocurrencies. Users seeking to make transactions via online platforms can use a hot wallet because the funds can be withdrawn on demand and be transferred via the internet to other users. However, a hot wallet is more likely to face security threats compared to a cold wallet.
In addition, a hot wallet comes with a higher level of security features compared to a cold wallet; hence, it provides a more secure way to store cryptocurrencies online. On the other hand, a cold wallet is used to store and hold funds and is entirely not connected to the internet.
How Does a Hot Wallet Work?
A hot wallet is connected to a web server, and it initiates a financial transaction involving cryptocurrency via browser-based webpages. It does not, however, store virtual currencies. Instead, its key role is to sign and authorize financial transactions digitally. The hot wallet server facilitates the conventional hot wallet service since it stores cryptographic keys and is accessible to the webserver.
After a holder decides to mine digital currency, the cryptocurrency network enforces a chronological order to safeguard the neutrality of the cryptocurrency system. A holder then decides where and how to store the tokens, forcing the financial transaction to be digitally signed. The transaction is then propagated into a cryptocurrency network.
Eventually, the record stored on blockchains becomes part of the shared public ledger. The collection of private keys and the cryptographic public keys are the essential components of a cryptocurrency transaction. Essentially, the private key is used to digitally sign an authorization and is similar to passwords, while a public key will verify the signature.
Hot Wallet and Security Issues
Hot wallet services with gaping security holes can be compromised by an unauthorized party. Importantly, the end user’s behavior largely determines the hot wallet’s safety and security. The public and private keys, which are stored on the internet, make hot wallets vulnerable to security issues.
For example, the single bottleneck system, such as the hot wallet server or an internet server where the end user’s verification occurs, increases the likelihood of message interception and online spoofing. If the username and password fall into the wrong hands, it may be possible to steal the virtual funds from a hot wallet.
It is recommended, as a cryptocurrency investor, to only keep a small portion of holdings in a hot wallet. Investors may choose to hold funds that they plan to use in the near future in their hot wallets. The rest of the funds will remain in their offline cold wallet with the backups of the private keys until there is a need to use the additional funds.
A majority of the top digital currency exchanges are compatible with the transfer of various cryptocurrencies and fiat currencies. Depending on a digital wallet, there are different security levels to protect the private keys. Some of the common forms of digital wallets include multi-signature wallets, mobile wallets, and software hot wallets.
