The Friendly Hackathon: Start Building on Casper!

September 13 - October 11, 2021

$135K+ in prizes

*Make sure to join the Casper Discord for dev support and to meet other hackers!*


After much anticipation, Casper is finally here… now, let’s build!

Earlier in 2021, Casper officially launched on mainnet. Long anticipated by developers seeking a more scalable and secure layer one protocol, Casper has already attracted a large and growing community of builders. 

Casper, the Friendly Hackathon

To celebrate the launch and stability of the Casper Network, the Casper Association is partnering with Gitcoin to create the Casper the Friendly Hackathon to support developers seeking to build innovative dApps on Casper. 

This challenge is open to developers of all experience levels, including Web2 developers who have been interested in building in Web3 environments but intimidated at the notion of learning new languages. Casper introduces the most seamless process for migrating Web2 apps to blockchain environments -- with zero Solidity knowledge required!

The Casper Association will provide support and guidance throughout the event to make this a collaborative, fun experience.
