Global hackathon launched to build next-gen Web3 apps on the Internet Computer

The DFINITY Foundation, in partnership with the ICP HUBS Network, has announced the launch of the World Computer Hacker League 2025 (WCHL25) — a four-month-long global hackathon set to run from July to October.

The competition invites developers worldwide to build production-ready applications on the Internet Computer blockchain, with registration now officially open.

Unlike traditional hackathons that push developers to churn out quick proof-of-concepts, WCHL25 provides participants with an extended timeline and access to a robust support ecosystem.

Weekly mentorship from blockchain experts, technical workshops, and office hours will be part of the package, equipping teams with the resources and guidance needed to bring viable products to life.

“WCHL gives developers what they've been asking for: real time to focus and build, real support from experts, and real pathways to growth,” said Emilio Canessa, Director of Global Adoption at the DFINITY Foundation.

“We’re not just running a hackathon — we’re creating the environment developers need to succeed.”

Participants will move through a structured four-stage competition: the Qualification Round, National Round, Regional Round, and finally, the Global Grand Finale, where top projects from every continent will battle it out for honors and prizes.

Submissions will be judged on technical execution, user experience, and real-world applicability by a panel of industry experts and key figures from the Internet Computer ecosystem.

The WCHL25 also taps into the global reach of the ICP HUBS Network, spanning North and South America, Europe, Africa, and Asia, to ensure a broad and diverse developer base.
