How to create a Bitcoin wallet app using popular libraries To gain the necessary familiarity with these concepts, we recommend this article by Michael Nielsen, as a starting point. For developers planning to code a Bitcoin wallet from scratch, a range of skillsets are essential that relate to blockchain technology.ĭevelopers need to understand the importance of the cryptographic hash function, the need for a decentralized protocol, how to prevent the problem of ‘double-spend’, ‘proof of work’ (POW) consensus algorithm, and public and private key cryptography. The Bitcoin protocol has its own unique characteristics. If you need to brush up on blockchain then a good starting point is this blockgeeks article. Many of the libraries and tools mentioned below presuppose a reasonable amount of knowledge on this subject.

These include full node, pruned node, and various application programming interfaces (APIs), which I will briefly touch upon.Īdditionally, a developer unfamiliar with blockchain technology should definitely spend the time to fully understand it. That said, there are various tools and libraries available to help developers. If you are not sure that your development team has the necessary skills or background to code a great bitcoin wallet app then we recommend considering outsourcing the jobs you are not sure about. As I said in the introduction, bad code will lead to project failure. Upon completion of the transaction, the wallet needs to broadcast the transaction to the Bitcoin blockchain.Ĭreating a Bitcoin wallet will require a set of good programmers.Must be able to build and sign Bitcoin transactions.The wallet should be able to dynamically calculate the fees based on the latest rates. Bitcoin transaction fees vary, based on several factors.The wallet needs to be able to handle the impacts of the Bitcoin blockchain database reorgs and other conflict resolution actions undertaken by the Bitcoin community.Remember, Bitcoins are basically just digital transaction histories. The wallet must store the transaction history, and be able to show it when needed.

At the other end of the spectrum, the wallet needs to recognize and process Bitcoin transactions being received from other addresses.

The wallet needs to recognize transactions and be able to send funds to the above-mentioned addresses.

It must generate the required Bitcoin addresses.

Here is a list of the main things a cryptocurrency wallet must do: Before undertaking Bitcoin wallet app development, any aspiring crypto developer needs to know exactly what the app needs to do.
