Build a Blockchain Wallet in 3 Hours- Workshop

Wallets are the core of most blockchain applications. Whether you want to build an exchange, an investment platform or a dApp, it is likely you will need a way for your users to store, send and receive tokens.

Developing a wallet for your application can seem daunting:

How do I get started?

How do I manage the private keys?

How do I build a safe infrastructure?

In this practical workshop, you will learn the basics on how to build a multi-user blockchain wallet, while being supported by a team of 6 senior Blockchain developers, who will follow you step-by-step in the creation of your first wallet.


The workshop is divided into 3 phases:


  1. Introduction to cryptocurrencies & our API offerings (30 min)
    • Our CTO, Jesper Noehr (founder of Bitbucket) will guide you through the basics concepts behind a bitcoin and an ethereum wallet (key generation, key management, seeds, recovery etc…).
  2. Tutorial – Develop a simple wallet (1 hour and 30 min)
    • We will give a small practical tutorial on how to build a wallet. You will get the setup right, authenticate, generate the first users, the keys and check the state of your user’s wallets and be notified of new transactions & balance updates. At the end of the tutorial, you will have created your first multi-user blockchain wallet.
  3. Pair with Blockchain developers (1 hour)
    1. Now it’s time to get creative. You might want to focus on transactions, on recovery, on data or something which is unique to your case. For the next 1 hour you will have the chance to build whatever you like and get instant feedback by a team of 6 blockchain developers.

Simply bring your laptop. During the workshop, you will use the Upvest Blockchain APIs. However, we are happy to guide you also through other APIs, during the workshop.
