callsheet is a prediction game for hackathons and contests. organizers list their event, owners claim their projects, predictors call the field. winners earn callpoints they can burn on raffles, or USDC payouts if a campaign was funded with a verified prize.
project owners claim their projects (verified by X handle match) and write campaign questions about them. some pledge USDC to fund a prize for predictors who call it right. predictors connect X, browse campaigns, and seal answers. once sealed, answers are permanent.
when an event resolves, callsheet scores ballots, picks winners, and posts a leaderboard. campaigns with verified pledges trigger payouts. predictors request payment with a sol wallet, payouts go out manually within a 7-day SLA.
callsheet was built by @25thprmr, a solo prompt-engineer-first builder. one of several projects shipping in parallel, alongside BagsBrain (the OS for bags creators) and HoppingHeads (a multiplayer arena game on base).
hackathons and contests have hundreds of submissions and almost no signal. callsheet turns it into a game: founders drive attention to their projects, predictors play, and everyone gets a clearer picture of which projects the community thinks have legs. if it's right enough times, it becomes useful signal. if it's wrong, it's still fun.
when a campaign resolves, scoring runs server-side and the result is final. the algorithm is public — the source is on github — but the specific scoring thresholds and raffle parameters are kept internal so the game can't be gamed. when things resolve, you'll see your score and the truth value side-by-side on /results.
a round runs through the listed events' resolution windows. results post when organizers (or admin, on behalf of an event) announce winners. payouts are manual, with a 7-day SLA on requested claims.
