Wallets

Ana Rojas

A cryptocurrency wallet is an application that serves as a storage location for your crypto. It is called a wallet because it is used in the same way as a wallet holds cash and credit cards. Modern cryptocurrency wallets make the blockchain accessible to everybody. When crypto assets were first introduced, sending them was a manual process that involved entering long keys. Today, software does the majority of the work for you. They are exceptionally important when it comes to the storage and management of digital assets.

A cryptocurrency wallet is more than a digital tool; it is an essential component in the realm of crypto transactions. It functions as a secure digital interface, allowing businesses and individuals to communicate with blockchain networks. A crypto wallet allows users to store digital assets, manage cryptocurrency portfolios, and conduct safe transactions. Unlike traditional wallets, a cryptocurrency wallet does not physically keep currency. Instead, it secures two types of digital keys: public keys, which are similar to account numbers for receiving payments, and private keys, which are similar to digital signatures used to authorize transactions.

To transact in crypto, you need two things: your wallet address (also known as your public key), and your private key. A public key is similar to your bank account number. You can send and receive money by sharing your bank account number with other persons or institutions. A private key is comparable to your bank account password or the PIN for your debit card, both of which are confidential.

Types of Cryptocurrency Wallets

There are three types of crypto wallets: hardware, software, and even paper:

Hardware Wallet

In blockchain technology, a hardware wallet is a cryptocurrency wallet that keeps private keys on a physical device, such as a USB drive. The hardware wallet has functionality from both ‘hot’ and ‘cold’ wallets. Hot wallets connect to the internet for easier access, while cold wallets keep your crypto keys offline for security. Hardware wallets, like paper wallets, allow their owners to securely store their private keys offline.  

In addition to keeping your private keys offline (where they cannot be compromised), most hardware wallets allow users to sign and confirm blockchain transactions by simply plugging their device into a computer. After a transaction is completed, a user can unplug their device and not worry about it remaining connected to the internet. This continual connection leaves a wallet open to attack. 

Software Wallet

The most common type of cryptocurrency wallet is a software wallet. This form of wallet is constantly connected to the internet. This persistent connectivity enables users to communicate with DeFi protocols seamlessly and efficiently. With a software wallet, you may easily borrow and lend, stake, swap tokens, and trade on DEXs (decentralized cryptocurrency exchanges). All DEXs use smart contracts to exchange cryptocurrency between parties. However, this connectivity does come with some drawbacks. A software wallet is continually connected to the internet, making it vulnerable to hacking.  

Paper Crypto Wallet

The third type of crypto wallet on our list is the most basic: a paper wallet. A paper wallet is basically a printed (or handwritten) sheet of paper with your private key and perhaps scannable QR codes. Though paper wallets are completely isolated from the internet and blockchain, the keys on them actually represent active keys on the blockchain that can be used to locate cryptocurrency.  

One of the main disadvantages of paper wallets is that they are stored on paper. If the paper becomes wet or burns in a fire, you will be unable to read your private key (or seed phrase), and the representative crypto will be gone forever. 

Step-by-Step Guide to Cryptocurrency Wallet Development

So, how to develop a cryptocurrency wallet? Here are the steps you need to take to create a crypto wallet:

1. Create an idea. Cryptocurrency wallet app development begins with an idea. The industry is still in its early stages of development, and many product ideas emerge from our personal experiences as we navigate around different weird issues. As you develop your vision, make sure to explore the world of blockchain and cryptocurrencies. You will most certainly encounter new challenges while learning about cryptocurrency and seeking a solution, and you will undoubtedly need to conduct competitive research. People may have already produced a product to answer the problem you’ve encountered. If that’s the case, look at ways to improve the product and make it more appealing to your target demographic.
2. Develop a plan. After determining what the industry lacks and what your potential customers require, the following stage is to create an executable plan. You must specify the features and functionalities that will be implemented during the cryptocurrency wallet development process.
3. Develop smart contracts, frontend, and backend. Next, you must create or locate smart contracts to fuel your cryptocurrency wallet’s features and functionalities. Even if you don’t have to construct your own smart contracts, you should understand the fundamentals. As a result, before diving into Web3 wallet development, you need first grasp the principles of Solidity, the largest and most popular programming language for creating EVM-compatible smart contracts. With the necessary smart contracts in hand, the next stage is to create the frontend and backend. The frontend handles user interactions with your wallet. Meanwhile, the backend infrastructure enables interactions between the blockchain and the frontend.
4. Testing. Before deploying your cryptocurrency wallet, you should always extensively test it to guarantee that everything works properly and without problems or mistakes.
5. Deployment and maintenance. Once you’ve confirmed that everything works as expected, the next step is to go live with your Web3 wallet. When your cryptocurrency wallet is up and running, it’s vital to continue to maintain it to ensure its lifespan. 

API Integration for Crypto Exchanges Inside the Wallet

Using APIs is an excellent technique to create a feature-rich cryptocurrency wallet application. A distributed ledger API enables you to effortlessly synchronize your cryptocurrency wallet with the blockchain ecosystem. Using APIs, your development team can perform the necessary processes quickly, speeding up app development. 

API integration is in essence a crucial tool for crypto wallets and aggregators, and one of the most convenient APIs on the market is one from StealthEX. Here are the benefits that StealthEX’s API integration offers:

Conclusion

Your wallet allows you to view your balance, send transactions, and connect to decentralized apps. Many wallets allow you to manage many crypto assets from a single application. That’s because wallets do not have custody of your money; you do. They’re simply a tool for keeping track of what belongs to you. That’s why, as any financial tool, it has to be user-friendly, secure, and easy to install. Whenever developing your own crypto wallet, make sure to do further research and consider incorporating additional features and functionalities based on your specific requirements and preferences.
