Finance Without Intermediaries: Superteam Poland Challenge at HackYeahMost transactions today rely on trust: in a bank, a payment provider, a platform or the other party. That middleman takes a fee, decides who gets served, and can block or reverse a transaction.The challenge: build an app on Solana that removes the need for trust from a financial transaction. Pick a relationship that currently needs an intermediary, such as escrow, freelancer–client payments, crowdfunding with conditional refunds, revenue sharing, parametric insurance, lending or B2B settlements. Then move its terms into an on-chain program. The program executes automatically and identically for every participant, and no one can change it unilaterally.Prizes (3,000 USDC total):<ul class="list-node"><li>1st place: 1,500 USDC</li><li>2nd place: 1,000 USDC</li><li>3rd place: 500 USDC</li></ul>Requirements:<ul class="list-node"><li>A working app on Solana (devnet is enough), not a concept or a mockup</li><li>At least one full user flow: connect wallet → transaction → result visible in the explorer</li><li>The logic that replaces the intermediary must live in the on-chain program, not in your backend</li><li>A clearly named target user, plus a short design rationale: which relationship you redesigned, who the intermediary was, and what changes once it’s gone</li><li>Submission: project description, PDF deck (max 10 slides), video up to 3 minutes, public repo with a README</li></ul>Judging criteria:<ul class="list-node"><li>Relevance to the challenge: 30%</li><li>Completeness &amp; functionality: 25%</li><li>Idea &amp; problem choice: 20%</li><li>Real-world potential: 15%</li><li>Originality: 10%</li></ul>
