Challenges Of Crypto Wallet Development

Create Your Own Cryptocurrency: Episode #3 – Wallet Interface

The crypto wallet development is a complicated task. So, you should be ready for the pitfalls you may face. Here is the list of the main of them.


The legal status of cryptocurrencies and blockchain technology varies significantly from country to country.

Initial costs

Blockchain promises long-term cost savings, but its implementation requires a high initial price.

Integration with legacy systems

To migrate to a blockchain-based system, a company must either completely redesign its existing system or integrate it with a blockchain solution both processes can take a lot of time, money, and experience

Power consumption

Blockchain networks require a significant amount of computing power to function this can be a limiting factor for many companies

Security and privacy

Since the network is publicly available, this poses some challenges for governments and corporations looking to protect their sensitive data.

Public opinion

Society is not ready for mass blockchains as most people are unaware of the technology and its potential benefits.

Is Creating A Cryptocurrency Legal

Creating a cryptocurrency is generally legal, although some countries and jurisdictions have partially or fully banned cryptocurrency. In China, for example, raising money through virtual currencies has been illegal since 2017 and all cryptocurrency transactions have since been banned. Even where cryptocurrency is legal, it’s possible to run afoul of existing securities regulations when launching and promoting a new cryptocurrency.

How Does A Cryptocurrency Wallet Work

  • It stores all the transaction records in the immutable blockchain network.
  • It operates in the form of a software program containing your private and public keys.
  • When a person sends his cryptos to another users wallet, he is transferring the ownership of the digital coins or tokens to the wallet address of the recipient.
  • The private key stored in your wallet must match the public address the currency is assigned to for unlocking the funds and utilizing them for various purposes.
  • The public key will be used to receive the funds and can be searched in the distributed ledger.
  • The private key is used to sign the transactions and prove that the user owns the related public key.

Software Wallets: Convenient Buying Selling Storing Trading And Using

  • Software wallets take the form of an app which is downloaded for free to your phone or desktop. You simply open up the app and can start making Bitcoin transactions almost immediately.
  • Since software wallets connect to the Internet, there’s a small risk of hacking. Therefore, it is generally recommended to not store large amounts of bitcoin in your software wallet. That being said, if you follow password management best practices, it’s safe to store bitcoin in a software wallet.
  • While there have been a few isolated cases of software wallets being hacked, by far the greater risk is that you lose your ‘private key,’ which is like the password to your wallet. Therefore, it’s critical to backup your wallet and store the password somewhere safe.

Tip: Make sure the software wallet youre using is fully non-custodial like the Wallet, meaning only you can access your cryptoassets not the wallet provider. This protects you from the risk of fraud or bankruptcy by the wallet provider.

So How Do You Secure Your Assets In A Wallet

  • Keep your passwords and private keys safe

Once someone has access to your passwords and private keys, your money is gone. Their safety should never be an option. A strong password is just the first step of securing your wallet. Also, you have to ensure no one else has access to your password and private key.

  • Enable Two-Factor Authentication

Use two-factor authentication for your login in process. Two-factor authentication requires a user to provide more than just a password and private key to access the account. Therefore even if someone accesses your password and private key, there is still missing information to complete the circuit.

  • Diversify risk

Avoid storing large amounts of digital tokens and coins in one wallet or exchange. By distributing your coins in several wallets, you reduce your risk significantly when tragedy strikes. With several wallets in play, stealing from all of them at once is close to impossible.

Working Model Of Cryptocurrency Wallet

Cryptocurrency wallets mechanisms based on cryptographic keys that are private keys and public keys. In case when a crypto user lewis sends a particular amount of cryptocurrencies to another person he wants to knows the public address. All particular transaction of sending and receiving gets stored on the blockchain and can never be altered.

Ways To Create A Cryptocurrency

Creating a coin

This option is not suitable if you are looking for an easy and fast way to create your own cryptocurrency free of charge. You need to be an experienced professional in decentralized technologies or have someone who is willing to take on the role of the technology expert.

The process of coin creation may take as little as 5 minutes. You can just copy the code of Bitcoin, add a new variable, or even change the value of something, and thatâs it – you have your blockchain and coin. However, you need to understand the code and how to change it, which requires extensive coding skills.

Another issue is to maintain, support, and promote the coin, as you have to create the whole logic of blockchain to launch your coin. Hiring a team of professionals to handle the task would save more time, but you would have to pay custom software development services. If you can afford to allocate a budget toward creating and supporting your own blockchain, go for it.

Creating a token

This is a more feasible way to become a currency creator. While having complete control over the blockchain may sound like a great idea, this has certain drawbacks like increased development time, significant spending, and much more.

In the table below, you will see the pros and cons of building coins or tokens:

What Is A Cryptocurrency Wallet

Create Your Own Cryptocurrency: Episode #4 – Mining

Before we move on to set up an account, lets look deeper at what a cryptocurrency wallet actually is.

For a starter, its nothing like the physical wallet you have in your pocket.

Its a software program that enables you to interact with blockchain technology. Digital wallets allow users to send and receive digital currency, as well as to monitor their balance.

Most coins have an official wallet, e.g. Bitcoinor Ethereum. Alternatively, they recommend third-party wallets.

Bitcoin is the most popular digital currency, hence there are dozens of wallets that offer services just for this currency. However, with the rise or altcoins, a majority of modern wallets will allow you to store multiple currencies.

How To Get Money Out Of Cryptocurrency Trading

The first and easiest option is to use a cryptocurrency exchange to withdraw your cryptocurrency. You can use a service like Coinbase to get your cryptocurrency. If you have 10 bitcoins and want to withdraw 2 bitcoins, you need to transfer those 2 bitcoins from your current wallet to your Coinbase wallet.

Are you looking to develop your own #Cryptocurrency Wallet ...
  • 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.

Are Cryptocurrencies Legal

Theres no question that theyre legal in the United States, though China has essentially banned their use, and ultimately whether theyre legal depends on each individual country. Also be sure to consider how to protect yourself from fraudsters who see cryptocurrencies as an opportunity to bilk investors. As always, buyer beware.

Creating The Chain Class

Now that we have our Block class ready, we can fill in those blocks in a Chain. A chain holds every block, or every transaction, that takes place on the blockchain. As discussed before, a blockchain contains all the blocks linked to each other, and our project needs a Chain class in order to keep all the blocks together in one place.

Because we only need to initialize the chain once and not multiple times, we will initialize it right away in the class itself:

class Chain 

Lets set up our constructor so that we have the first block ready in the chain whenever the program is run. This will also set up the array where our blocks are placed.

We do this to eliminate any errors in our project, because we depend on the previous block in parts of our code, so we need a dummy block initialized at first:


Now, we need a function to get the last hash of the chain, in order to use the information in new blocks:


Next, lets create a function that will actually create and insert a block into our chain array:

insertBlock }

Here, we are first using the createVerify function from the crypto package to verify hashes with the public keys. We then use the data from the JSON of a particular transaction, and finally verify by providing the senders public key and the signature.

Now your Chain class should look like this:

class Chain   getPreviousBlockHash   insertBlock   }}

Wallets Accounts And Addresses

It’s worth understanding the differences between some key terms.

  • An Ethereum account is an entity that can send transactions and has a balance.

  • An Ethereum account has an Ethereum address, like an inbox has an email address. You can use this to send funds to an account.

  • A wallet is a product that lets you manage your Ethereum account. It allows you to view your account balance, send transactions, and more.

Most wallet products will let you generate an Ethereum account. So you don’t need one before you download a wallet.

What’s An Ethereum Wallet

Your wallet is only a tool for managing your Ethereum account. That means you can swap wallet providers at any time. Many wallets also let you manage several Ethereum accounts from one application.

That’s because wallets don’t have custody of your funds, you do. They’re just a tool for managing what’s really yours.

    Create An Ethereum Token

    In order to create your own cryptocurrency, you will need to use the ETH wallet app that can be found and downloaded here. When you open the wallet app, at the top right corner, you will see a button as depicted below, âDeploy New Contractâ, click it.

    Once you click, a Solidity Contract Source Code field will pop up. Enter this code in the field that pops up.

    The phrase âmappingâ stands for an associative array, which associates balances with addresses. All addresses are in hexadecimal format. âPublicâ, which is bolded, means that anyone will be able to see balance. After you add the line of code to the Solidity field, your screen should look like this.

    However, this doesnât mean that your cryptocurrency has actually been created. What you need to do now is add another line of code under line 4 in the Solidity code box as follows:

    Your initial token supply will be 21 million. However, you can easily set this amount to anything you like. Letâs take a glance at the right side of the application. Click âSelect Contract to Deployâ and a drop-down window will open. Click âMyToken.â

    Increased Regulation In 2021

    How To Make Own Cryptocurrency Wallet

    The rise in the popularity of cryptocurrencies and their adoption by financial institutions has led some governments to assess whether regulation is needed to protect users. The Financial Action Task Force has defined cryptocurrency-related services as “virtual asset service providers” and recommended that they be regulated with the same money laundering and know your customer requirements as financial institutions.

    In May 2020, the Joint Working Group on interVASP Messaging Standards published “IVMS 101”, a universal common language for communication of required originator and beneficiary information between VASPs. The FATF and financial regulators were informed as the data model was developed.

    In June 2020, FATF updated its guidance to include the “Travel Rule” for cryptocurrencies, a measure which mandates that VASPs obtain, hold, and exchange information about the originators and beneficiaries of virtual asset transfers. Subsequent standardized protocol specifications recommended using JSON for relaying data between VASPs and identity services. As of December 2020, the IVMS 101 data model has yet to be finalized and ratified by the three global standard setting bodies that created it.

    The European Commission published a digital finance strategy in September 2020. This included a draft regulation on Markets in Crypto-Assets , which aimed to provide a comprehensive regulatory framework for digital assets in the EU.

    Creating The Wallet Class

    Now lets create the wallets, which the users can use to send cryptocurrencies to other people. Each crypto wallet has a pair of keys: a public key and a private key. The private keys are used to create new transactions and the public key is used to verify them and receive cryptocurrencies.

    Lets first set up the constructor so that we can generate a key pair as soon as the wallet is initiated:

    constructor ,    privateKeyEncoding: ,  })   this.privateKey = keys.privateKey   this.publicKey = keys.publicKey }

    Here, we are using the PEM format for the keys. It is a well known format and can be saved on the users PC. The RSA algorithm allows us to create public and private keys.

    Now lets create a function that will help us to send cryptocurrencies to other wallets on the network:


    In the above code, we take amount and recieverPublicKey as parameters and create a new object from the Transaction class using that information. We then create the hash of the transaction and sign it with the private key. Finally, we add it to the chain using the insertBlock function.

    How To Create A Successful Cryptocurrency Show

    The first step to creating the best cryptocurrency is to create a blockchain. Blockchain technology is the backbone of all the cryptocurrencies you see in the world today. The blockchain contained the details of each cryptocurrency. This is a ledger that shows the history of every cryptocurrency you own.
