Attendee Profile

Cardano Buidler Fest is very much focused on building and operating software on Cardano, but we strive to be open to other blockchain eco-systems.

Our participants are expected to be a diverse crowd of developers, sysops, product designers, UX/UI experts, and more generally anyone not afraid to get their hands "dirty" by actually doing interesting, intriguing, or even amusing stuff within the Cardano eco-system.

People proficient with other blockchain ecosystems, whether UTxO or Account-based, are also welcome to share their experience and knowledge building actual applications and systems.  


Speakers who need it (ie: from outside Toulouse, not covered by their own company) can have their expenses covered up to a maximum amount of €300. Expenses will be reimbursed after the conference upon presentation of expenses' bills.
