For almost everything you might want to do in the web3 world — whether it’s trading cryptocurrency, enjoying play-to-earn games, or investing in NFTs — you need a cryptocurrency wallet. It’s the best way to use and manage your digital assets, and keep track of what they’re worth. But did you know that not all cryptocurrency wallets are the same?
There are a number of different kinds available, such as custodial and non-custodial wallets, and although they offer similar functionality, the way they operate is very distinct. The type of cryptocurrency wallet you need depends on what exactly you want to do with it. In this AAG Academy guide, we’ll teach you the differences, and help you decide which is best for you.
A cryptocurrency wallet is essentially a piece of software. Think of it like a traditional online banking app; you can use it to keep track of your balances — how many tokens you hold as well as how much they’re worth — and to transfer cryptocurrency tokens back and forth. The most popular wallets hold multiple different kinds of cryptocurrency token — as many as you like.
However, not every wallet is compatible with every cryptocurrency. For instance, if you have a custodial wallet, it will only hold tokens that have been acquired on the wallet’s own exchange, which is why many cryptocurrency traders tend to carry multiple wallets, at least one of which is custodial and at least one of which is non-custodial.
That may not be necessary for you, depending on what kind of cryptocurrency you want to buy and how you want to use it. If you’re only interested in investing in the biggest cryptocurrencies like Bitcoin and Ethereum, for instance, you might only need a custodial wallet. If you want to invest in smaller projects and use DApps, you’ll need a non-custodial option.
Unlike traditional bank accounts, which use account numbers, sort codes, and internal bank account numbers (IBAN) for routing, cryptocurrency wallets use two digital keys. One of these is public and the other is private. They’re both long strings of letters and numbers (usually 14-64 digits) and they’re tied together, but they serve different purposes.
The public key is what’s used to make cryptocurrency transfers. It’s the key you’ll share with others when they want to send you tokens, and the key others see when you send tokens to them — like your bank’s account number and sort code.
The private key, which is not shared with anyone else, is a digital signature that’s used to authorize your cryptocurrency transactions. Without this, it’s not possible for someone else to withdraw or transfer tokens from your account — even if they know your public key.
It’s handy to know what these keys do, but you don’t have to remember them. Cryptocurrency wallets usually take care of that for you.
As we’ve touched upon above, there are multiple types of cryptocurrency wallet, and each is available in multiple forms. These are currently the most popular options:
Mobile cryptocurrency wallets, which you can download from the App Store on iPhone or from Google Play on Android, are the most popular kind because they make managing your tokens — and keeping an eye on your balances — incredibly convenient. They’re also easy to set up.
Much like a mobile banking app, a mobile cryptocurrency wallet lets you access your tokens and trade or sell them from anywhere, so long as you have an internet connection.
Desktop wallets are much like mobile wallets, except they run on your computer rather than your smartphone. Some desktop wallets can also be accessed on a mobile device; however, others can only be used on the computer on which they were installed. These can be installed as a standalone application or as a browser plugin.
Hardware wallets are stored on a physical device, which typically looks like a USB storage stick, that you can take with you wherever you go and use on almost any computer.
A custodial cryptocurrency wallet app, otherwise known as a centralized wallet app, is one that’s controlled by a central entity. They are usually offered by centralized exchanges, such as Binance and Coinbase. Custodial wallets give you the ability to send and receive cryptocurrency tokens, but they do not give you full control over your funds or your private keys.
A non-custodial wallet app like MetaMask or Trust Wallet, otherwise known as a decentralized wallet app, is one that is not controlled by a central entity. It gives users complete control over their funds and their private keys, eliminating the third-party.
Like most things, centralized and decentralized wallets have their pros and cons, and it’s very important to take note of these before deciding which is the best solution for you. Here are the key things to consider:
Those who are new to cryptocurrency trading typically find that centralized wallets are the best place to start. Although you have to jump through some hoops to get set up, the process can be more welcoming for newcomers. Acquiring and trading cryptocurrency can also be simpler through a centralized wallet, and there’s support available if you need it.
However, if you feel comfortable enough with taking full responsibility for your digital assets, a decentralized wallet gives you greater flexibility — including access to more cryptocurrency tokens across many decentralized exchanges, and decentralized apps (dApps). You’ll be able to do whatever you want with your assets, and it will be up to you to protect them.
Some wallets are beginning to give users the best of both worlds. For instance, the upcoming AAG Wallet does away with complicated seed phrases in favor of more advanced and more secure login systems, while still providing users with access to the most popular decentralized exchanges and fiat gateways.
Of course, you don’t have to choose just one wallet. Most traders use both centralized and decentralized wallets for different purposes, and there’s nothing to stop you having as many wallets as you like. In fact, if you spread your cryptocurrency holdings across multiple wallet apps, you greatly reduce the risk of losing them all as a result of one failure.
Cryptocurrency wallets use blockchain technology and cryptographic security, so they are considered to be safe. However, as is often the case with things of this nature, it is up to us as users to ensure our wallets do not fall into the wrong hands. You should never share your wallet’s seed phrase with others or use untrusted services.
An NFT wallet is a place to store any NFTs you have acquired. Many of today’s biggest cryptocurrency wallets now store NFTs as well, and many provide access to NFT marketplaces.
One of the simplest ways to get started with a crypto wallet is to download one to your smartphone. Starting out with centralized wallets like Binance and Coinbase is a good idea, but if you want to invest in smaller projects or use DApps, you may want to use wallets like MetaMask and Trust Wallet instead. The upcoming AAG Wallet is also a great place to start..
