Hot vs Cold Wallet vs Hardware Wallet

Anyone that invests in cryptocurrencies or is involved in trading
Decentralized Finance (DeFi) assets or Non-Fungible Tokens (NFTs) will
need to have a crypto wallet to manage their assets. Unlike traditional
wallets, crypto wallets allow users to execute smart contracts that
exist on blockchain technology.

Crypto wallets
explained

Crypto wallets are software or physical devices which store all the
keys crypto owners need to access their particular blockchain network
and manage their cryptocurrencies. Unlike wallets, which hold physical
currency, these wallets—and the keys they contain—are crucial to being
able to store and transfer crypto coins. Because cryptocurrencies are
digital assets that exist only on blockchain technology, owners are
given public and private keys when they register a wallet. These
function as proof of ownership of the crypto coins and act as
identifiers whenever owners want to access their assets. It is therefore
essential that the keys are stored safely and that the crypto wallets
are protected by security measures and managed carefully. The Winklevoss
twins—the first Bitcoin billionaires and alleged co-founders of
Facebook—famously protect their private keys by printing
them out
and storing snippets of these in various safety deposit
boxes across the United States.

Cold
wallet vs hardware wallet: Understanding the difference

As there are different types of crypto wallets, understanding the
differences between them and how each one works is essential for
choosing the best wallet for each user. The easiest way to have crypto
wallets explained is to understand that there are two categories: hot
wallets and cold (or hard) wallets. The first exists only digitally and,
because they are always online, are significantly more vulnerable to
hacking and phishing attacks. But,
hardware wallets—of which cold wallets are a subcategory—are physical
and, because they exist offline and in the real world, it is much harder
for malicious actors to attack these. Of course, each type of wallet has
a much more detailed list of attributes, and crypto owners should do
their due diligence to decide which wallet will suit their needs
best.

For example, some users prefer the convenience of hot wallets—because
these are digital, they can be quickly accessed from any device.
However, more advanced users looking for additional security for their
digital assets might opt for crypto wallet hardware—or even cold
wallets. Owners also need to consider the compatibility of the different
crypto wallets because not all work across the different blockchains and
cryptocurrencies.

What is a hot wallet?

A popular choice for crypto owners, hot wallets are digital storage
solutions for private keys—the proof of ownership all owners get when
they purchase cryptocurrency. Because they are a type of software hosted
online, hot wallets are always connected to the internet. Designed for
convenience, users can access hot wallets to quickly access, manage, and
transfer their assets. But, because the wallets are always online, they
are also easy to attack. As such, it is especially critical for users of
hot wallets to take additional security measures to protect their
wallets, keys, and crypto, such as using strong
passwords.

What is a hardware
wallet?

So, what is a hard wallet, and how does it differ from a hot wallet?
The main thing to understand is that hard wallets—or hardware
wallets—are physical, not digital. These might be, for example, USB
drive-like devices. They also store a user’s private keys—and thus, act
as proof of ownership of crypto assets. Hard wallets allow users to
authenticate crypto transactions, executing smart contracts across
blockchains.

In addition to this, hardware wallets allow users to use numerous
blockchain addresses. This is crucial because it allows users to keep
their different crypto assets separate yet accessible through one portal
and authorize transactions only with specific blockchains containing the
assets the user wishes to transact. However, even though crypto wallet
hardware stores keys separately from exchanges, because they still
interact with Web3, these devices may have some vulnerabilities. As
such, hard wallets may still be exposed to hackers. For example, these
wallets may inadvertently be used to sign malicious smart contracts that
send assets to a hacker.

Hardware
wallet vs cold storage wallet

Cold storage wallets—or simply cold wallets—are a specific type of
crypto wallet hardware. Perhaps the most important difference between a
cold wallet vs hardware wallet is that cold wallets offer an additional
layer of security to protect a user’s assets. When considering what a
cold storage wallet is, users should understand that these are
completely disconnected from the internet and do not involve any
interaction with Web3—and, therefore, do not execute smart contracts on
blockchains. Instead, these wallets work in tandem with active wallets
to execute transactions. In many cases, it is possible to create a cold
wallet on existing crypto wallet hardware and use this to sign
transactions through the active wallet. Because they operate completely
offline and do not have Web3 interaction, cold wallets are considered
the most secure type of crypto wallet.

Security for crypto
wallets

It is crucial that crypto owners and traders implement security
measures that protect their crypto wallets from cybercriminals. Using
crypto wallet hardware while understanding what a cold storage wallet is
and how it can secure your assets are two useful actions. However, many
users still prefer to use hot wallets because of the convenience they
offer. In these cases, it is especially essential that users understand
how to secure their crypto wallets properly. These measures might
include:

  • Using a VPN to encrypt all transactions.
  • Creating and managing strong passwords with a password manager.
  • Install anti-virus software on all
    devices, and ensure these are up to date.
  • Remaining alert to potential phishing scams.
  • Using multi-factor authentication.

A
Crypto wallets List: The Wallets to Know About

1. Coinbase Wallet

As one of the biggest crypto exchanges, Coinbase offers three crypto
wallets. Coinbase Wallet is the most versatile of these. For example, it
works across numerous exchanges, including Uniswap and 1inch,
cryptocurrencies like Bitcoin, and BNB, and even Decentralized Finance
(DeFi) assets and NFTs. Perhaps most usefully, it partners with Ledger—a
popular crypto wallet hardware provider—to offer offline hosting that is
compatible with Coinbase Wallet’s digital features. In addition to these
features, Coinbase Wallet allows users to connect bank accounts from
most major institutions, features an intuitive user interface, and
offers biometric authentication. It is even possible to create a
Coinbase Wallet without using the exchange itself. This decentralization
is useful because it ensures that a user’s keys would not be exposed if
the exchange was hacked.

2. Crypto.com DeFi Wallet

Part of Crypto.com, this particular hot wallet is specifically
designed for DeFi and NFTs. Users can manage over 800 cryptocurrencies
through this wallet, including Bitcoin, Ethereum, Cosmos, and USD Coin.
The Crypto.com DeFi Wallet also offers multiple layers of security
through the inclusion of features such as two-factor authentication and
password encryption.

3. Metamask

Popular with those who own and trade the Ethereum currency, MetaMask
is a hot wallet offering full access to an unprecedented collection of
tokens and decentralized apps on the Ethereum blockchain. However, the
popularity of the MetaMask crypto wallet is also explained by its
compatibility with various other blockchains, such as Polygon, Binance
Smart Chain, and Avalanche, and NTF marketplaces, including OpenSea and
Rarible. MetaMask is built on open-source code, which means it is
constantly being tested for vulnerabilities and issued with security
patches, which helps keep it secure. Along with a well-designed and
easy-to-use interface, users can access their wallet through any Android
or iOS device, or as an extension on browsers such as Google Chrome and
Mozilla Firefox.

4. Trust Wallet

Trust Wallet, part of the Binance company, is one of the most popular
crypto wallets for users who need support for dApps and NFTS, thanks to
a native Web3 browser. However, it also supports 65 different
blockchains, making it compatible with over 4,500 digital assets. All of
this comes with a very user-friendly interface that makes the app
suitable even for beginners but offers charts for price tracking for
advanced users.

5. Ledger Nano X

As well as being a renowned name in crypto, Ledger offers crypto
wallet hardware. There are three devices available, but the Ledger Nano
X strikes a useful balance between being easy to use and offering full
functionality. A prime example of how hardware wallets work, the device
features an OLED screen and Bluetooth connectivity and is compatible
with the Ledger Live app for seamless asset management. In addition, the
Ledger Nano X supports NFTS and more than 1,000 crypto coins and offers
several security measures, including a 24-word “Secret Recovery Phrase,”
PIN protection, and a CC EAL5+ secure element chip.

6. Trezo Model T

The Trezor Model T is another example of crypto wallet hardware which
elevates the meaning of what a hardware wallet is. From the device’s
1.54-inch color LCD touchscreen, users can manage 1,456 coins and
tokens, including Bitcoin, Ethereum, and Litecoin, and trade without
fees. The Trezor also offers high-level security, including the Shamir
Backup for creating multi-word recovery seed keys, user-defined PINs up
to 50 digits long—or user-generated passphrases—and independent,
physical verification required on the device for every transaction.

Understanding Crypto
wallets

Crypto wallets are an essential tool for anyone involved in
cryptocurrencies and other digital assets. However, understanding how to
distinguish between the different options on crypto wallets is essential
to deciding which will work best for a particular user’s needs. As well
as knowing the advantages and disadvantages of hot wallets and cold
wallets vs hardware wallets, users should do their due diligence with
the multitude of crypto wallet hardware available and decide which will
be most useful for them—and most importantly, will keep their assets
secure.
