Featured match


Real calendar from the fixtures oracle. Times in UTC.

MiroShark is a general social-simulation engine. MiroBall does the football part: it finds the match, frames it, and pays for the run.
Every 3 hours MiroBall sweeps the public ESPN scoreboard across 13 competitions and keeps the next 22 days, national teams and clubs.
Kickoff, venue, bookmaker odds, and club or country framing go into one prompt, with a pinned market: Will the home side win?
About 25 agent personas argue across simulated Twitter, Reddit, and Polymarket for 10 rounds. You get a report with belief drift and market moves.

Every run carries the x402aff affiliate field, so half of MiroShark's net profit on the run comes back to MiroBall.
With a registered builder code, the X-Builder-Code header adds an on-chain 10% split at settlement through an ownerless 0xSplits contract.
