How To Make Your Own Crypto Wallet

How To Make A Cryptocurrency Wallet For Bitcoin And Other Crypto Coins

Scary Easy: Build your own Crypto Wallet

The chances are you or one of your friends are already trading or investing in crypto. No other asset fluctuates by 50%+ in a matter of days, tempting us with mad gains. No other banking product earns us 15%+ APY of the passive income. No fiat currency empowers us to transact anonymously. And all this fun starts with a crypto wallet.

So if you plan to create a crypto wallet and need advice on how to best approach that without learning code, heres the best guide for a non-technical founder.

Top Takeaways:

  • The first thing to decide when you build a crypto wallet is to choose whether youre making a custodial or non-custodial crypto wallet. Crypto enthusiasts and people in the know predominantly work with non-custodial wallets, whereas newbies see no difference.
  • It takes a lot of effort to develop a bitcoin wallet from scratch, but in exchange, you get a more secure solution without compromising its functionality to the limitations of crypto SDKs.
  • Supporting fewer coins lets you launch your crypto wallet faster since you dont need to integrate it with various blockchain networks, hosting multiple cryptocurrencies.
  • Our Experience in Crypto Wallet Development
  • Challenges You May Face When You Make A Bitcoin Wallet

    What issues are you likely to run into during your crypto wallet development? The most common technical and business challenges include:

    • Blockchain forks, which happen not so often, but when they do, you need to decide which version of a blockchain your wallet will support
    • The necessity to integrate with multiple blockchains to support more coins
    • Despite the hype, adoption is still a challenge because most customers interact with many unknowns for the first time
    • Most crypto products that fail rarely get a second chance, at least under the same brand
    • Finding a capable team of developers who are equally versed in user-centric design and blockchain technology

    Speaking of technologies, lets quickly review the tech stack required for building a crypto wallet in the next section.

    What Are Cryptocurrency Wallets

    Cryptocurrency wallets are like the leather wallets some of us still use in real life for carrying cash and a slew of credit cards.

    But there are some thingsyour leather wallet cannot do. For instance, when checking how much you have, you have to count through your notes and coins. Your wallet doesnt tell you when you last spend some money from it, or who you tipped at a restaurant.

    So, while your physical wallet is great and all, you have to do all the thinking and record keeping.

    As digital apps, cryptocurrency wallets are a lot smarter and combine all the advantages of your physical wallets with more sophisticated flexible features.

    With just one wallet, you can hold hundreds of digital currencies without worrying about ever running out of space. All are neatly packaged into clearly marked sections, so you dont mix them up. Also, a handy balance checker keeps track of crucial details such as when, where and how much you spent, added or withdrew. There is even an option to scribble a note next to any transaction you make so you can look back on it later and pinpoint exactly where that odd dollar wound up.

    If you plan on acquiring some digital currencies for investment or remittances or what have you, you want to familiarize yourself with how they work.

    What Is A Crypto Wallet App

    A crypto wallet app is a downloadable piece of software, available via the App Store or the Google Play store. The app stores the private keys that are needed to access your cryptocurrencies. It can be accessed via your mobile phone or on another portable device, similar to how online banking apps work. Crypto wallet apps are great if you think youll need to access your crypto wallet on the go.

    Create A Token By Using Specialized Platforms

    Youve been wondering how to create your own cryptocurrency, starting with creating a token? Another easier way to create your own cryptocurrency is to use the services of platforms that give you the tools to launch your own token. This option is more feasible for those who are looking to quickly launch a crypto, as it requires less development time, spending, and maintenance.

    When you build a token on top of an existing blockchain, such as Ethereum, your token uses the secure network, decentralized architecture, and implemented consensus mechanisms of the blockchain.

    Tokens function similarly to smart contracts and can be programmed to represent various items or have different digital services. Tokens are usually launched in ICOs of Security token offering to help projects and startups get the funds they require for their operations.

    Do I Need To Generate A Private Key

    Most of the time you dont. For example, if you use a web wallet like Coinbase or Blockchain.info, they create and manage the private key for you. Its the same for exchanges.

    Mobile and desktop wallets usually also generate a private key for you, although they might have the option to create a wallet from your own private key.

    So why generate it anyway? Here are the reasons that I have:

    • You want to make sure that no one knows the key
    • You just want to learn more about cryptography and random number generation

    Crypto Hardware Wallets And Why They Are Important

    How to Create a Crypto Wallet

    Since crypto exchanges are not fit for the storage of digital assets, then the place to store them is crypto hardware wallets. The main advantage of crypto hardware wallets is that they are cold. Cold means that the primary gateway of your digital assets and private keys is not used and revealed online.

    Furthermore, the private keys of a cold wallet never leave the confines of the physical wallet, unlike hot wallets in which internet servers hold your cryptos.

    One of the reasons why crypto-hardware wallets are crucial is that Centralized exchanges are prime targets to cyber attackers, and they get hacked too often. On the other hand, do not need users to relinquish control over their private keys.

    You can use different cold-storage hardware offerings, and there is no shortage of options to keep your cryptocurrencies safe. But these hardware wallets can range from $50 to $200. Hence, this article is not about spending an average of $50 on a new hardware wallet. In the following, find out how to make a crypto hardware wallet yourself!

  • How Do I Back Up My Crypto Wallet

    Create Offline Paper Wallet

    To protect against computer failure or software issues its good practice to back up your crypto wallet. How you do this will depend on the software you are using. For example, Bitcoin wallets will ask you to generate and record a 12-word backup phrase that you can use to restore your wallet if you lose access. These can sometimes be a 24-word phrase, but the process will be similar with all companies. Make sure you look into what you need to do with your particular software, so youre ready to back it up when needed.

    What Exactly Is A Private Key

    Formally, a private key for Bitcoin is a series of 32 bytes. Now, there are many ways to record these bytes. It can be a string of 256 ones and zeros or 100 dice rolls. It can be a binary string, Base64 string, a WIF key, mnemonic phrase, or finally, a hex string. For our purposes, we will use a 64 character long hex string.

    Why exactly 32 bytes? Great question! You see, to create a public key from a private one, Bitcoin uses the ECDSA, or Elliptic Curve Digital Signature Algorithm. More specifically, it uses one particular curve called secp256k1.

    Now, this curve has an order of 256 bits, takes 256 bits as input, and outputs 256-bit integers. And 256 bits is exactly 32 bytes. So, to put it another way, we need 32 bytes of data to feed to this curve algorithm.

    There is an additional requirement for the private key. Because we use ECDSA, the key should be positive and should be less than the order of the curve. The order of secp256k1 is FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141, which is pretty big: almost any 32-byte number will be smaller than it.

    Cryptocurrency Wallet Development Reasons

    Now that weve outlined the types of cryptocurrency wallets, let’s find out why cryptocurrency wallet development is a worthwhile initiative.

    • Safer payments. Payments within the blockchain network are transparent, secure, and irreversible. Moreover, they are anonymous. This combination will almost completely eliminate the risk of fraud.
    • Speeding up international transactions. It still takes a long time to make international payments as each intermediary bank checks the transaction data and thus delays the receipt of the payment. The blockchain network is transparent and secure, so cryptocurrencies can be sent and received almost instantly.
    • No governmental control. This is a rather dubious advantage since cryptocurrencies in the hands of cybercriminals and lack of control is not the best scenario. However, blockchain enables companies to earn money honestly and allows users to spend it at their discretion.
    • Attracting modern users. The majority of the public is not yet ready for the full adoption of cryptocurrencies, but a number of progressive users have long appreciated their benefits. If your business is aimed at tech-savvy users, they will appreciate the idea of a custom cryptocurrency wallet.

    Testing And Configuring Your Trezor Wallet

    After flashing the firmware if you connect the trezor to your computer it should be detected and the drivers will install automatically . After driver installation finished you need to go to trezor.io/start as prompted on the display of the trezor. You will be instructed to install a small piece of software that acts as a bridge between windows and their web service. After that is installed your new device should be detected by their online app and it should prompt you to upgrade the firmware if a newer version is available.

    After upgrading the firmware the trezor app will offer you the possibility to setup and configure your new hardware wallet and this means you have successfully completed the project.

    Technology Stack For Cryptocurrency Wallet Development

    How To Make Your Own Hardware Wallet For Free!

    First of all, different teams choose technologies based on their experience. Therefore, its entirely possible to work with varying stacks of tech to build crypto wallets. At the same time, there will need to be some basic blockchain foundation for such crypto projects. Heres an example of a tech stack that will work.

    Read our article: How to Choose Your Tech Stack

    Mobile apps

    This one is pretty easy: Kotlin for Android, Swift for iOS. These native programming languages supported by Google and Apple offer the most advanced toolsets for making a mobile crypto wallet for iPhones and Android smartphones.

    React and Node.js are modern web development tools with plenty of instruments available on the market.

    Server-side specifics

    Youll need Kubernetes and Docker for building a scalable architecture Golang and Solidity to take care of smart contract development and then Python, Ruby, or any programming language that will serve to make the back end admin portal.

    Thats really a barebones description of a tech stack for developing a crypto wallet. Think of it as yet another incentive to collaborate with your development partner if they have some experience working with these technologies. We also shared more details about how to create a blockchain application in a separate blog.

    What Is A Bitcoin Wallet App

    Before proceeding to the question of how to build a bitcoin wallet, it would be useful to understand what it is, to begin with.

    The universal cryptocurrency wallet might be considered as your personal channel of interaction with the Bitcoin network, just as online banking acts as a “bridge” between you and the financial system.

    Bitcoin wallets contain private keys: secret codes which allow you to spend bitcoins. In fact, you need to store and protect not the bitcoins themselves, but these private digital keys that provide both access to public bitcoins, and the ability to conduct transactions.

    In short, a Bitcoin wallet is an application, site, or device which:

    • contains private keys for your bitcoins

    • helps to conduct all kinds of transactions of getting or transferring Bitcoins

    • allows checking the data about your cryptocurrency balance.

    And, of course, such wallets are rather different, depending on the device with which they are going to work.

    We should discuss the issue in more detail before considering the future of mobile wallets and how to create one of them.

    Web Wallets : Convenient Buying Selling And Trading

    • Centralized cryptocurrency exchanges have traditionally been a popular place for many newcomers to buy their first bitcoin because they make the buying process very simple. It’s like opening a trading account.
    • However, the cryptocurrency exchange itself retains control over the funds in your account. Not only does this expose you to the risk of the exchange getting hacked or going bankrupt, it also means you have to ask for permission to withdraw your bitcoin, wait longer to withdraw, and usually pay higher transaction fees for withdrawals.
    • We recommend using cryptocurrency exchanges only for trading .

    Tip: Cryptocurrency exchanges are not a secure place to store digital assets. Once youve bought your bitcoin, you’re advised to move it to your software or hardware wallet if you don’t plan on trading it immediately.
