Paris Blockchain Week Hackathon 2025 Winners Announced

[PRESS RELEASE – Paris, France, April 7th, 2025]

Paris Blockchain Week, Europe’s leading blockchain event, has officially announced the winners of its Onsite Hackathon, held over the weekend at VO2 in central Paris. The competition brought together some of the most promising blockchain developers and innovators from across the globe for a high-energy, two-day sprint to build the next generation of Web3 solutions.

This year’s hackathon introduced a new hybrid format, combining several weeks of online challenges and workshops with a dedicated in-person build event. While online winners were announced last week, 1st place Agrify Technologies, 2nd Stripped Chain, and 3rd Myrkle, the Paris-based finale focused squarely on in-person collaboration, rapid prototyping, and live pitching under pressure.

The Onsite Hackathon kicked off on April 5 with a full schedule of workshops and sponsor briefings. Leading blockchain platforms including XRPL Commons, Solana Foundation, and Bahamut presented technical challenges to participants, who then spent the weekend forming teams, designing applications, and coding side-by-side with support from on-site mentors.

By Sunday afternoon, projects were finalised and submitted, with each team given the opportunity to pitch their solution live to a panel of judges made up of protocol experts, VCs, and industry leaders. Judging took place on site and winners were announced shortly after.
