Do these three things first

Colosseum's Crypto World's Fair runs from Sept 14 to Oct 12, 2026, with $840,000 in prizes and $2.5 million in seed funding. It's open to any chain, and we support Balkan teams building on Solana.

1. Register on Colosseum. Pick your country and city (there's no region option), then choose 1 to 3 chains, including Solana.
2. Fill in our form so we can reach you.
3. Join the hackathon Telegram group with your cofounders. We answer questions and announce calls there.

Submit by Oct 12, 11:59pm Pacific (08:59 on Oct 13 in Belgrade). Prizes and judges each have their own section below.

Buildstation Belgrade is on now, through Demo Day on Oct 13. Register on Luma to get the venue.

Everything below is optional, except two rules that can get you disqualified: one project per team and per person, and you must list all work done before Sept 14 in your submission. Details are in the Submission checklist.

Superteam Balkan has helped startups raise over $9M and given $650k+ in equity-free grants. Teams from our community won prizes at three Colosseum hackathons: Verve and Genesis at Radar; Hobba, Hyperstack, Nomu and SP3ND at Cypherpunk; and Nomu again, with JK Index, in the Frontier Top 25. We won nothing at Renaissance or Breakout, and we kept entering.
