There are several different types of crypto wallet with the main ones being software and hardware wallets. Within software wallets you also have two sub-categories: custodial and non-custodial crypto wallets. 

Cryptocurrency wallets play a vital role in safeguarding your digital assets, as well as managing your funds and portfolio, with providers offering a number of options to cater to the various needs of different users. Understanding the types of crypto wallets and their advantages and disadvantages is crucial for maintaining the security of your funds and maximizing potential gains.

In this educational blog post, we'll delve into the diverse world of cryptocurrency wallets, shedding light on their types, functionalities, security measures and suitability depending on users’ knowledge.

What is a Crypto Wallet?

A cryptocurrency wallet acts as a gateway to engage with blockchain networks such as Bitcoin, Ethereum and Solana, as well as DeFi applications, NFTs and other forms of digital assets. 

There are three primary types of crypto wallets: 

1. Hardware wallets
2. Software wallets
3. And paper wallets. 

Software and hardware wallets generate private and public key pairs, with the address serving as a destination for receiving cryptocurrencies, NFTs and digital assets. 

The public key is an address that can be shared. But the private key must be kept confidential because it is how the owner accesses their crypto funds and assets. 

Public Keys, Private Keys and Seed Phrases

When you initially create your crypto wallet, you will be given a public key and a private key to access it.

A public key is a long string of digits (typically a combination of letters and numbers) that allows its owner to receive cryptocurrency by encrypting sensitive data.

The primary function of a private key is to verify both transactions and ownership of a wallet address. A private key achieves this with an algorithm that both decrypts and encrypts sensitive data.

A public key is just like your mailbox - people can see this address and use it to send you mail, (or in this case, crypto).

However, only the owner of this mailbox has the key to open it and actually access the messages and mail stored inside. With this analogy, this key is the same as the ‘private key’ for your crypto wallet.

Although the private key and public key are mathematically connected it is impossible to derive a private key from a public key alone. This helps towards the linked wallet’s security.

Never share your private key with anyone. If you do so, that person or entity could steal all of your digital assets.

Most modern wallets use ‘seed phrases’ instead of private keys. A seed phrase is a long series of random words, usually 12 or 24, which are linked to a private key. Owners should write their seed phrase on a piece of paper (or two) and hide them in a couple of different places for enhanced security.

The Different Types of Crypto Wallets

1. Software Wallets:

Connected to the internet, suitable for daily and regular transactions, but are considered less secure because they are online.

Software wallets, also referred to as ‘hot’ wallets, are the most popular form of crypto wallet in the world of Web3. This type of wallet is always connected to the internet (hence the alias ‘hot’ wallet). This constant connectivity allows users to quickly and seamlessly interact with DeFi protocols, smart contracts and other blockchain based activities.

Borrowing, lending, swapping, staking, and also trading on DEXs (decentralized exchanges) are smooth and easy with software wallets. All DEXs deploy smart contracts to swap cryptocurrencies and digital assets between parties.

However, this connectivity does come with some disadvantages. Because a software wallet is always connected to the internet, it is at risk of being hacked. And threats to software wallets are not limited to cyberspace.

If you misplace or lose an unlocked device upon which your wallet is located, the recovering party could very easily gain access and drain the crypto from your wallet. It is therefore important to always have any device that contains a software wallet safeguarded by a password

• Beginner friendly and easy to use.
• Prone to hacks and malicious attacks due to being online. 

2. Hardware Wallets:

Offline and therefore often referred to as ‘cold’ crypto wallets. Because hardware wallets are not connected to the internet, they are considered more secure for long-term holdings, but are far less accessible for regular transactions.

They come in the form of a physical device that resembles a USB drive. Hardware wallets are like paper wallets in that they allow their owners to safely store their private keys offline.

In addition to safeguarding your private keys offline (where they can never be hacked or targeted by malware), most hardware wallets allow users to sign and confirm transactions by just plugging their device into a laptop or computer.
After a transaction is complete, a user can unplug their device, and not have to worry about it being constantly connected to the internet.

• Physical devices like Ledger and Trezor.
• High security, less access and less user-friendly for newcomers to crypto.

3. Paper Wallets

A paper wallet is simply a printed or hand-written piece of paper that has your private key and sometimes a scannable QR code written or printed on it. 

Though paper wallets are completely disconnected from both the internet and blockchain, the keys on them do indeed represent keys on the blockchain which are still active and can be used to locate cryptocurrency.

• Printed QR coded form wallet.
• Less popular due to limitations and inability to send crypto, NFTs and other digital assets.

Within software (or ‘hot’ crypto wallets), as well as custodial and non-custodial forms, they also come in various types depending on the hardware you’re using to manage and store your cryptocurrencies. 

4. Desktop Wallets

• A form of software wallet - this is installable software for operating systems like Exodus and Electrum.
• They balances security and convenience.

5. Mobile Wallets

• Another type of software wallet - designed for smartphones, uses QR codes for transactions.
• Convenient but vulnerable to malware.

6. Web Wallets

• Another form of software wallet - accessed via internet browsers like MetaMask and Coinbase.
• Super convenient but less secure, suitable for small investments.

Custodial and Non-Custodial Wallets

Apart from hot and cold wallets, understanding custodial and non-custodial wallets is also vital to navigate the world of crypto and Web3.

Custodial and non-custodial are two types of crypto wallet under the software or ‘hot’ wallet category. 

• Custodial Wallets: Third-party controlled, user-friendly and great for beginners, potentially provides account recovery services.
• Non-Custodial Wallets: User-controlled, enhanced security, but no recovery options, user has full responsibility and control over their digital assets and their safety.

How Crypto Wallets Work

Acquiring a wallet: Receive a wallet when purchasing digital assets, usually a hot wallet.

Understanding wallet types: Differentiate between hot and cold wallets based on security preferences.

Transferring to cold wallet ): Enhance security by transferring assets to a cold wallet for long-term storage.

Cryptocurrency storage: Cryptocurrencies exist as data on a blockchain; wallets manage public and private keys.

Key components: Wallets consist of a public key for receiving and a private key for transactions.

Accessing and transacting: Use the private key for transactions, similar to a digital signature.
