What is a Cryptocurrency App?

Cryptocurrencies are just digital numbers recorded in a complex ledger called a blockchain. As such, to interact with the coins, buy and spend them require apps. Apart from these, several apps offer different kinds of information related to cryptocurrencies, such as their price movements and news. The rise of DeFi has also led to complete lending and borrowing ecosystems using smart contracts that can only be accessed through the apps.

How do Cryptocurrency Apps Work?

As interfaces for accessing information and the cryptocurrencies themselves, these apps work by creating a front-end UI that people can use.

The apps come in different versions, each designed for a specific operating system. The first step is to find the app that will work with your device (Android, desktop, iOS etc.). Many app developers also create the same app for different platforms, so if you have two or more different devices, you will be able to use the same type of app.

Apps such as price tracking and news can be simply downloaded and run. Registration may not be a part of it at all. However, if a cryptocurrency app is designed towards handling finances, such as wallets, exchanges etc, these will require the user to register themselves.

Typical registration requires the users to create their login credentials: a username and a password. Depending on the app, a person’s email address itself may be used as a username. The app may also use the email address to send a security code/link to verify the user.

If you are creating a cryptocurrency wallet, the registration process might end at this point, giving you access to your newly created crypto wallet. Wallet owners will need to fund their wallet and that is possible through going to the deposit option and copying the public key provided. This key is the identification of the wallet and needs to be sent to any person who wishes to transfer the cryptocurrency to the wallet owner. Once the wallet is funded, the cryptocurrency will reflect in the balance.

Wallet holders are also able to send cryptocurrencies. They need to navigate to the Deposit or Transfer option. Transferring of cryptocurrencies involves entering three different sets of information: the number of coins, the public address of the recipient wallet and the transaction fee. Several crypto wallet apps support multiple cryptocurrencies, so it is paramount to make sure that the right wallet address is selected. Sending a cryptocurrency to another blockchain will result in the coins being lost.

Cryptocurrency exchanges are also registered on more or less the same principle as any other crypto app. However, since these apps have serious money matters involved, they require users to pass KYC and AML checks as per regulations. The KYC can be integrated into the registration process or after it. Crypto exchanges can even have a step-wise KYC, where certain levels are defined based on the trading volume of the user. Each level unlocks enhanced trading, deposits and withdrawals.

KYC process, although varying from app to app and regulators, requires some basic documentation such as:

  • Official ID, issued by the government.
  • A copy of a recent utility bill with the name and address clearly mentioned or any other document showing the registered address of the user.
  • Proof of income to trace the funding of the cryptocurrency exchange account.

The exchanges might ask for more information, subject to the locality of the trader and the app developers. We would like to mention that there are crypto exchange apps that advocate the privacy of their traders and require no KYC checks at all. Though this can be very attractive for people who are uncomfortable with handing over their personal information, the risks of these exchanges being scams is very high. Requiring no KYC, these apps are probably not registered with any regulatory firm and therefore, are not bound to protect their users’ assets. The developers can run away with the cryptocurrencies of their users. Keeping themselves anonymous under the garb of privacy for all, they will also be untraceable.

The funding process of a crypto exchange app is very similar to a wallet, with the funds being deposited through the given public address of the relevant crypto. Some cryptocurrency trading apps also offer fiat support and can accept bank transfers and/or credit cards. Once the exchange account is funded, the users can trade cryptocurrency by selecting their required trading pair and using the available order options. If a trader desires to withdraw assets, they can do so by heading to the Wallets section and requesting a transfer just like they would do in a crypto wallet app.

Key Things to Consider When Choosing The Best Cryptocurrency App

Every cryptocurrency app is developed to cater for specific uses with some having more than one functionality and even are cross-platform compatible. With thousands of options available today, it can be a bit difficult to decide which one to use. The selection criteria can become tough when using crypto apps such as wallets and trading ones as this can involve serious monetary funding.

When selecting a crypto app that will suit best, there are a few general aspects to keep in mind. The developers should be reliable and have a good track record. Since the apps also pull information from different resources and blockchain itself, the authenticity of data should also be high on the list of priorities. The interface should be easy enough to understand and use.

In case of apps that allow storing and spending of cryptocurrencies, the security takes top priority. A good app with an excellent team behind it and a great interface with proper data input can still be too risky if there are security lapses that can lead to the users’ funds being stolen or lost. Apart from this, the app should have good funding options. Exchange apps can be very tough to use if the right cryptocurrency is not on its list. An app that supports fiat funding can also be useful in case the user or trader needs to deposit or withdraw traditional money.

When it comes to the movement of cryptocurrencies, there are different kinds of fees involved. Sending crypto to another wallet requires a transaction fee, while trading apps charge a commission for every trade made. These fees can vary from app to app.

If your requirements include frequently using the app, you might also want to look into the supported OS. Mobile ready apps can be very handy as it allows instant use through mobile devices from anywhere.
