🍐 Built on Pear · Tether Hackathon 2026
PearCup packs bracket pools, synced watch parties and a best-of-five penalty duel into one candy-coated desktop app — every lobby, room and rematch running peer-to-peer over Hyperswarm. No accounts. No cloud. Just match day.
Tonight’s line-up
Real screenshots from the app — pink pixels, live swarms, zero mock-ups.

Pick every round from the Round of 32 to the Final, drop into a USDT tier, and sweat the live leaderboard with your friends. Every pool shows its prize total, entrant count and closing timer.

Pillar 02 · Watch parties
Spin up a match room on Hyperswarm: friends’ avatars on the couch, live room chat, emoji reactions and live match data from the Football-Data.org feed. One invite link and the whole squad is in.
6 on the couch · room open · invite link ready
Spain/Austria room is up. No fake score until the feed lands.
Pillar 03 · Penalty Clash
A best-of-five P2P penalty shootout. Challenge a real friend over the swarm with an invite code — or warm up against AI keepers, each with a record and a stake. You take five, you keep five. Outscore them for the win.
With no server in the middle, QVAC is the referee: it validates every shot and save between the two peers and seals each round with a signed receipt, so neither player can fake a result.
Pillar 04 · QVAC AI + Tether WDK
QVAC follows the match with multilingual live commentary — and it's the trusted referee for the peer-to-peer games too, sealing every penalty duel and pool settlement with a signed attestation. The in-app Tether WDK wallet handles USDT entries, escrows and payouts — every settlement surfaces its receipt hash in the UI.

🍬 Wallet & commentary run in demo mode for the hackathon — the P2P networking is fully real.
The P2P playbook
From kickoff to payout in four moves — peers only, end to end.
One command in the Pear runtime — pear run --dev . — or launch
pear://pearcup-kawaii straight from PearBrowser.
Choose your nation and grab a kawaii jersey — your profile lives with you, not on someone’s server.
Lobbies, match rooms and watch parties are Hyperswarm topics. Peers discover each other directly — invite links, no middleman.
Brackets score live, QVAC narrates in four languages, and the WDK wallet writes settlement receipts you can verify in-app.
Ships as a staged hyper:// payload for PearBrowser — manifest, icon, release gates and smoke checks included.
