Portaldot Mini Hackathon S1 is a lightweight hackathon running from April 20 to May 31, 2026, organized by the Portaldot team. It is designed for developers who want to quickly build a prototype, validate an idea, and showcase their work without the complexity of a full competition format. The event emphasizes low barrier participation, runnable MVPs, and clear demos. The hackathon is open to developers worldwide, particularly those familiar with Rust, Ink!, and Substrate. Participants are expected to build on the Portaldot blockchain, use POT as gas, and deliver a functioning MVP with open source core contracts. Submissions require a GitHub repo, README, and demo video.
