Blockchain Wallet Development: What is it & How To Build From Scratch?

This article is the perfect guide to help you create one if you are looking to build a Bitcoin wallet application. Technology has been revolutionising the digital currency sector by introducing currencies independent of the market’s physical status and with a completely decentralised system.

With Bitcoin, there is a possibility to have real-life virtual money, and it can be redeemed to be exchanged for products. When talking about currency with no physical existence, there has to be a way to keep them for better allocation.

Thus, the need for wallets, with a Bitcoin wallet app, you can have instant access to send and receive bitcoins with being private and anonymous at the same time.

Initially, this might seem a bit hard to get a hold of things, to understand how this works.

To make it an easy process, let us break it down into steps

Basics Of Bitcoin And Its Significance

The primary term blockchain means a collaboration of informative digital datasets connected with the help of chains cryptographically. The best part about the blockchain mechanism is that it can be unchanged.

There is complete transparency. There is no intervention from intermediaries like the government and the banks eliminating additional costs. 

The data is accessible through any device but is unbreakable due to its encryption.

Bitcoin is a result of an idea that Satoshi Nakatomi had in 2009, who coined the term digital currency. This led to the inventions of much more coins in the same stream.

There are more than 5000 cryptocurrencies in the global market, and the numbers are still growing.

What Is Bitcoin Wallet

A bitcoin wallet is a safe and secure place to store, buy, and sell bitcoins or any other cryptocurrencies. 

Three Ways To Access The Wallet With The Help Of The Following


This can be electronic safe deposits or wallets that can be accessed with desktops and mobile devices.


The data regarding the account and coin details are stored on a hardware device for better accessibility at all times.


 Paper format print-outs are visual proof of existence for bitcoins, making it a liability as it always poses a threat of getting misplaced and destroyed.

Building An App From Scratch 

It is always recommended to use pre-existing methods for the blockchain wallet development process in the initial stages. There are quite a few tools and methods that are adopted by many developers, as they are easily compatible with the wallet app and also process each transaction made through the blockchain network. 

To build an app requires coding with significant programming skills. Here is a list of things that a programmer needs to address to avoid failures during the first time.

For Better Ease Of Flow, It Is In The Approach Towards Each Of These Steps.

  • Synchronize the blockchain network with the help of API and tools.
  • Develop the program with all the necessary programming and permissions for outgoing and incoming transactions.
  • Conduct tests at each stage to ensure that the implementation standards are maintained at each stage of developing the platform. 
  • It is essential to build a team that would be liable for the full node development of the bitcoin blockchain. This development team would work on fully synchronising the node and the related operations can be done with the RPC commands.
  • A proper cloud platform is required for the app development, it would help manage the cloud infrastructure, operating system, runtime diagnostics and networking.

How A Bitcoin Wallet App Functions

A Bitcoin wallet transaction is made based on an asymmetric key with cryptography for better security. This can be accessed with the help of a public key and private key.

When a transaction is made from one account to another through a wallet, there is an exchange of coins from the owner to the seller.

These transactions are recorded and analysed with the help of respective Bitcoin wallets. Learn More Difference Between Ethereum and Bitcoin

Technology Stack

There is an abundance of public libraries that can be used for blockchain app development  in the online space. One can use these libraries to implement the standard functionalities.

 If looking to build a web application, Angular JS 4.0 must build the front end and HTML5 and CSS3, whereas for the backend Node JS is used.

The Android app will require the code input from Java to build an extensive frontend, and as for the API services, Python should be implemented for the backend.

In the case of the IOS app, the swift method can be implemented, which is similar to the Android version using Node JS or Python.

The bitcoin wallet app can be provided better security with additional features such as 2-step authorisation. This will raise any irregular activity related to the account.

This is due to the rise in popularity of bitcoins and the wallets to store them. It’s essential to be secured and have configured the features right to rest depending on the wallet’s usability.

Bitcoin has proven to be a big game-changing player in the market; it’s essential to stay updated with the newest developments in the crypto world. Simultaneously, there are continuous efforts to build a bitcoin wallet, as the demand for them has skyrocketed.

Though it is challenging to build a wallet, with high rewarding compensation for such solutions, there would be a great position to hold in the lucrative market.


 It is a great time to start Blockchain app development. The rise in popularity of bitcoin apps has increased the demand for bitcoin wallet apps, where the only expectations from an online wallet is to be safe and secure.

It is certain that in the coming years other currencies would also require crypto wallets and the demand for them would be consistent.
