Hack Your Way to the Borderless Economy

Algorand makes it simple and fast for developers to build on blockchain. With Java, JavaScript (node.js and browser), Go, and Python SDKs, along with REST APIs, you can build on Algorand in your preferred programming languages. Easily get up and running writing node or web applications on Algorand and quickly integrate with applications in common languages.

Why Build on Algorand


Visit developer.algorand.org for access to all of our dev tools. 

  • We encourage you to use this Hackathon Lab Exercise to familiarize yourself with all of the Algorand developer tools. This exercise includes step by step instructions for: Getting Started, Private Network, Goal command line, AlgoExplorer, SDKs and Resources.
  • Feel free to communicate and ask questions with others in the community on gitter or on discord
  • Use any of the dev tools provided and leverage our SDKs and APIs to create a unique application on Algorand! 
  • Bonus if you write to and read from the ‘note field’

Upcoming Hackathons


Using any of our dev tools qualifies your team for prizes. However, the judging team will give preference to teams that demonstrate creative competence by:

  1. Using one of the SDK’s
  2. Writing to and read from the notefield in a transaction
  3. Using multiple dev tools

An example solution would be to: Build a solution for easy account management using one our SDK’s, the solution should be able to:

  • Create and sign txns, do the same with multisig accounts, recover accounts from mnemonic
  • Bonus: Build a UI for the solution (command line, web based or other) in any language. There is a webapp example is in the JavaScript SDK.
