What are “Hot Wallets”?

Crypto Hot Wallets are wallets that can be accessed when connected to the internet. This type of wallet is also connected to the cryptocurrency network. It has an interface that can be used to view how many tokens you have (although these tokens reside in the blockchain). You can also buy, send, store, receive, and swap tokens conveniently.

Hot wallets have a public and private key, which aids in transaction processing. The public key is your receiving address and is used to receive tokens into your wallet. Just like the way a bank works—to get money deposited in your account, you have to present your account number to receive the funds—so does a public key. The private key, on the other hand, is what helps you sign transactions and also signifies ownership of funds and should be kept private at all times, hence the name private key.

How hot Wallet Works

Before buying a cryptocurrency, you have to set up a wallet with which can use to facilitate transactions conveniently. The wallet is created to store your cryptocurrencies and it contains both a public key and private key. The public key helps your receive tokens into your wallet while the private key shows that you have ownership and helps you sign transactions. Without either of these keys, the wallet is effectively useless.

To interact with hot wallets you must be connected to the internet. They basically provide an interface for you to interact with the blockchain. Hence, every token you see in a wallet doesn’t reside in the wallet but in the blockchain. They help you store, receive, send, and swap tokens with ease.

When a transaction is initiated Instead, its the key role of the wallets private key is to sign and authorize the transaction and after it has been validated by the blockchain nodes its then propagated into the cryptocurrency network. Eventually, the record is then stored on the blockchain and hence becomes part of the shared public ledger.

How are Hot Wallets hacked?

Importantly, the end user’s behavior greatly influences the safety and security of the hot wallet. Hot wallets are vulnerable to security issues because their public and private keys are stored on the internet.

For example scammers create phising sites (a clone of a major website) that will require you to give access of your private keys to interact with the platform. Some crypto users have fallen victim to this and have lost huge amounts of their funds in the process. 

Also, a single bottleneck system, such as a hot wallet server or an internet server where the end user’s verification takes place, increases the possibility of message interception and online spoofing. It is possible to steal virtual funds from a hot wallet if the username and password are compromised.

Investors may choose to keep funds in their hot wallets that they intend to use frequently like buying cryptocurrencies, trading etc. While the remaining funds should be kept in their offline cold wallet along with backups of the private keys until they are needed.
