Multi Cryptocurrency Wallet Development: Complete Guide

With everything moving digital, investment strategies are too. After gold, real estate, stocks, and bonds, now people are investing in cryptocurrency. You can get an idea about the popularity of the cryptocurrency market with the fact that the global cryptocurrency market was valued at USD 1.3 billion in 2021. The market is expected to show a CAGR of more than 12%. 

What Is Cryptocurrency?

Cryptocurrency is a digital currency that works on blockchain technology. The price of cryptocurrencies varies as per the demand and supply, and if the demand exceeds the supply, the price will increase and vice-versa. Some popular cryptocurrencies are Bitcoin, Ethereum, Ripple, Monero, etc. Many crypto exchange platforms are available in the market where you can trade cryptocurrencies.

What Is a Cryptocurrency Wallet, and Why Do You Need It?

A cryptocurrency wallet is a storage unit where you can store all the cryptocurrencies you have bought. It can be in the form of hardware and software, depending on the type of cryptocurrency wallet you are using. 

Cryptocurrencies are based on blockchain technology and don’t have any physical evidence. So, you can not store them in your locker, pocket, or traditional wallet. Your cryptocurrency wallet is an address where you receive your cryptocurrencies and store them securely. 

How Do Crypto Wallets Work?

Cryptocurrency wallets are software apps on mobile devices or computers, like tablets or phones. Using an internet connection, they access the blockchain network for the cryptocurrency you are leveraging. 

You may need to correct a misconception that cryptocurrencies are stored somewhere. But, the fact is they are data bits stored in a database. Such bits are scattered all over the database, and the wallet finds such bits linked with users’ public addresses. Next, in the app’s interface, they sum up the amount for the users. 

Using such apps, sending and receiving cryptocurrency using varied methods is easy. 

Sender Side: 

• Enter the recipient’s wallet address, 
• Choose an amount to send, 
• Use your private key to sign the transaction, 
• Append an amount to pay the transaction fee and 
• Send it. 

Many wallets with integrated QR codes and well-infused near-field scanner technology allow users to scan a code, choose an amount, enter their key, pick the transaction fee, and click send. 

Receiver Side: 

On the other end, 

• The sender enters your address to receive the amount, and the routine goes the same. 
• The user accepts the payment, and the transaction is complete.

What Does Blockchain Technology Refer To? 

Blockchain is a distributed database, also known as a ledger shared among the nodes of a computer network. Blockchain is made up of different blocks attached in a sequence. Every block carries some sort of information depending on its respective usability. 

Blockchain technology has come into the limelight with its increasing role in the cryptocurrency system. Blockchain technology is used in the decentralized record of cryptocurrencies like Bitcoin. A slight alteration in one block will require a massive change in every other block of the chain. So, it is nearly impossible to make changes in the blockchain.

Types of Cryptocurrency Wallet

Just like the cash and card wallets, you have a number of cryptocurrency wallets to choose from. However, here you won’t go for the appearance but the functionality of the wallet. Cryptocurrency wallets are divided into two main categories: hot and cold wallets. 

Hot Cryptocurrency Wallet

Hot wallets are cryptocurrency wallets that connect with the internet to perform transactions. Due to connectivity with the internet, a high risk of hacking and security is experienced. But, hot wallets are user-friendly and provide a smooth user experience. Hot wallets are available in further three categories:

1. Desktop Wallet

Desktop wallets are the applications that you can download on your desktop and laptop. The desktop wallet generates the data file that holds the keys for the users. Moreover, the users are allowed to set the password to access the keys stored in the wallet. Desktop wallets have the least risk of physical damage or malware infections. 

3. Mobile Wallet 

Similar to a desktop wallet, you must download the mobile wallet on your smartphone. The biggest flex you will get with the mobile wallet is that you can trade the crypto from the same platform. So, it makes the storage and transactions more friendly to you. 

Cold Cryptocurrency Wallet

On the other hand, cold wallets operate without support and connectivity to the internet. So, these are much safer than hot wallets. But, the wallets are not connected to the internet, and you will have to connect them to your system to make crypto transactions. So, these offer better security but less accessibility. Cold wallets are available in the following categories:

1. Hardware Wallets 

Cryptocurrency doesn’t have any physical entity, but hardware wallets have. It looks like a pen drive that stores your key away from internet connectivity. There is no chance of hacking or malware attack as it can never be connected to the internet. You can connect the hardware wallet to your computer with a USB drive. 

2. Paper wallets 

If you are confident that you can store and manage a piece of paper not getting stolen or damaged, paper wallets can be one of the options for you. However, paper wallets are nothing but a piece of paper with a key. If your paper wallet is stolen or damaged, you can assume that you have lost your investment for life. 

Custodial and Non-Custodial Cryptocurrency Wallets

1. Custodial Cryptocurrency Wallets

When a third party holds your cryptocurrencies’ private key, it is a custodial cryptocurrency wallet. The third-party holds complete access to your cryptocurrencies in a custodial cryptocurrency wallet. 

Free Wallet, BitMex, Bitgo, Binance, etc., are some of the leading custodial cryptocurrency wallets. 

2. Non-Custodial Cryptocurrency Wallets

On the other hand, non-custodial cryptocurrency wallets provide complete control of tokens to users. There is no engagement of third parties in this type of cryptocurrency wallet. 

Electrum, Ledger Nano X, Trezor One, Exodus, Zengo, etc.,  are some popular non-custodial wallets. 

What Are Multi-Cryptocurrency Wallets

Most cryptocurrency wallets are meant for storing specific crypto and don’t work with multiple cryptocurrencies. Litecoin Core is the desktop app wallet that only holds Litecoin coins and tokens. 

So, the cryptocurrency wallets that can store multiple cryptos simultaneously are known as multi-cryptocurrency wallets. For example, most hardware wallets can store multiple cryptocurrencies in them. At the same time, the crypto stored on exchange platforms can also be counted in multi-cryptocurrency wallets as you can store numerous cryptocurrencies. 

Multi-crypto wallets are available in both hardware as well as software form. 

1. Hardware Multi-Crypto Wallet

A hardware multi-crypto wallet comes in the form of a pen drive or card-readers that can store your multiple cryptocurrencies. The range of multiple cryptocurrencies might differ from wallet to wallet. One might carry 3 different cryptocurrencies while the other can hold 5. 

Ledger Nano S, SafePal S1, SecuX V20 Most Secure, etc., are some of the best multi-crypto hardware wallets that can be considered. 

2. Software Multi-Crypto Wallet

For easy access, software multi-crypto wallets have your back if you prefer to use a software wallet. Software multi-crypto wallets can be in the form of web wallets and application wallets. 

Multi Crypto Blockchain Wallet is a good example of a Software multi-crypto wallet. You can store more than 150 coins in this application. This software wallet is available for Android as well as iOS users. 

Key Features of A Crypto Wallet 

1. User Authorization 

Security is the first concern of users while using a fintech app. Moreover, the growth and craze of cryptocurrency have brought the threat of cyber attacks and security risks. So, user authorization is one of the must-have features for a crypto wallet. Having two-factor or multi-factor authentication can be a significant element in attracting users. 

2. QR Code Scanner

Convenience always attracts customers. Having a QR code scanner to get the wallet address and make the transaction can transfer the app’s usability to a significant level. 

3. Multiple Cryptocurrency Wallet

As we observed earlier, most crypto wallets are meant for a single or specific cryptocurrency. The wallet that can manage multiple cryptocurrencies simultaneously can be a significant differentiating factor. 

4. Efficient Management of Familiar Addresses 

It will be a plus point if the wallet can manage all the frequently used addresses, and it will elevate the smoothness, speed, and convenience of transactions. 

5. Sending and Receiving Crypto

The modern software wallets offer to send and receive the crypto instantly from any address. Equipping this feature in your app can enhance its usability. 

6. Payment Gateway

The price of one bitcoin might be thousands of dollars, but one can not trade it for shopping at a regular supermarket. So, everyone expects monetary benefits from their investment. Integrating a payment gateway will make it easier for the users to exchange their cryptocurrency profit with real-time money.  

7. Push Notification

Push notification enhances the user’s experience. The cryptocurrency wallet should have the feature to notify the owners about the rise or drop in the price of their cryptocurrencies. 

8. Customer support 

You have to be available whenever your customers need you. Ensure the use of various tools such as chatbots, customer care executives, FAQs, etc., to provide efficient and complete customer support. 

9. Automated logout 

Automated logout is another feature to enhance the security of the crypto wallet. The app should log out of the user account automatically after a period of inactivity or closing the app. It will ensure that a third person is not misusing the account or application. 

Are Cryptocurrency Wallets Secure?

The security of cryptocurrency wallets varies on several factors. The foremost determining factor of wallet security is the type of wallet you are using. The fact can not be denied that web servers are constantly exposed to cyber security risks such as breaching and hacking. Talking about offline wallets, they can not be hacked or breached as offline wallets are far from the connectivity of the internet. So, there are no chances of data breaching or hacking. 

Irrespective of the wallet you are using, losing/sharing/breaching your key will directly cause the loss of your investment.  

How to Develop a Cryptocurrency Wallet App?

Developing a fintech app is complicated as compared to other regular apps. Users and app developers might not afford any kind of bug or error in the application as it might cause a significant financial loss to both parties. Unlike the majority of app development, here, you first need a complete understanding of blockchain, cryptos, required APIs, the right tech stack, security system, etc. 

However, we have listed some of the steps and considerations that you can entertain while developing a cryptocurrency wallet: 

1. Get Familiar with The Concept of Blockchain and Cryptos

The whole game of crypto, selling, buying, and storing is based on blockchain technology. So, before initiating the process, you must be familiar with Blockchain. Cryptocurrencies work only because there is blockchain technology supporting it. 

2. Use “standard Cryptocurrency Open-Source Libraries.”

Most cryptocurrencies are open source, and you can use the available free libraries and tools. BitcoinJ SDK and Coinbase SDK are good examples of the same. 

3. Use APIs

To install the excellent feature, you have to install an API. While developing a cryptocurrency wallet, you need to use a distributed ledger API to allow the synchronization of the crypto wallet to the blockchain ecosystem. Coinbase, Factom, or Bitcore can be your choice for the APIs. 

4. Go Cloud 

Selecting the right cloud platform is crucial while developing the cryptocurrency wallet app. BaaS (Blockchain as a Service) providers are the best cloud service, in this case, to integrate into the app. A number of companies offer BaaS products, such as Amazon, Microsoft, and Azure. 

5. Ensure the Right Technology Stack

Tech Stack is the framework that determines the functionality of your app. Make sure you use the right tech stack to provide the best experience to the users. 

• Node.js or Angular.js with HTML5 and CSS3 can be the right choice when developing a web app. 
• Similarly, you can use Java or Kotlin to build the native Android app. 
• Swift or Objective-C can be used to develop iOS apps. 

6. Equip Security 

You never know what amount of investment the user will store in a crypto wallet. So, security will be their foremost concern when choosing the wallet. You need to make sure that your app is equipped with top-notch security. You must add extra layers of security to your app, such as 2FA, fingerprints, face lock, etc. 

7. Focus on Competitive Advantages 

With the increasing popularity of cryptocurrencies, many crypto wallets are available on the app store and play store. You will have to secure competitive advantages so that your app can stand out from the crowd. For the same, you should keep an eye on your competitors regarding their features, the customers they are targeting, and the technology they are incorporating. Never let your app lag behind your competitors.
