HackMeridian is a two-day hackathon at ONE16 in Lisbon where developers, founders, designers and technical teams build working products on the Stellar network. It is tied to Meridian 2026, Stellar's annual conference, which follows in the same city on 28 and 29 October.
There are two tracks. Genesis is for new ideas and early prototypes, and Scale is for teams moving an existing product toward production. The organizers say prizes total up to $30,000 in XLM and that the top projects move forward to the Meridian conference.
