Join our Hack-O-Ween Hackathon!

Following on from our wildly successful Stellar hackathons in London and Toronto, we're headed to Boston where we're inviting the world's top students from Harvard, MIT and others to join us for our Hack-O-Ween Hackathon.

Over the course of 36-hours, you'll get to meet the team behind Stellar, one of the world's leading blockchains, while building the future of real-world finance.

Stellar's helping millions across the world get access to the world's financial system and this is your chance to play a vital role in furthering their mission.

Winners of our past EasyA x Stellar hackathons have gone from winning hackathons to raising millions in just months.

Whether you're a university student, seasoned developer, or finance professional, you won't want to miss this one.

Not a programmer? This hackathon is open to everyone regardless of technical experience (whether it’s ideation, marketing or presenting). We even have a special prize dedicated for non-coders!

Free to enter. Free food. Free code-level support available in-person 24/7.

"On behalf of the entire team here, we wanted to extend a sincere thank you for all of your support during the earliest stages of the Lockbox. The two hackathons we did last semester were monumental in turning a random late-night idea into a functional MVP."
