Duels are 1v1, winner-take-all trading battles — no lobby, no waiting on strangers to fill a bracket. You pick the fight. Here’s how to set one up.
Duels run on the same simulated trading engine as every competition — you and your opponent each trade with practice capital, priced off live Kraken market data. The entry fee is the only real USDC at risk, and it’s exactly what you put up — no more.
1

Pick your asset

Choose the market you and your opponent will both trade. Whatever you pick is locked for the whole duel — same asset, same rules, same clock, for both of you.
2

Set the stakes

Set the entry fee in USDC — minimum 1,thoughtheappdefaultsto1**, though the app defaults to **50. Both sides post the same amount. Whoever wins takes 2x their entry, the full pot — no platform fee.
3

Set the duration

Choose how long the duel runs — minimum 5 minutes, defaulting to 1 day. You can also set a start delay — immediately, 5 minutes, 15 minutes, or 1 hour. Trading begins the moment your opponent joins, plus whatever delay you chose.
4

Set max leverage

Drag the leverage slider anywhere from 1x to 100x — default is 25x. This is the ceiling both of you trade under for the entire duel.
5

Choose your opponent

Leave it open to anyone, or send a directed challenge to a specific friend. Directed challenges land straight in their Invites tab, not the open pool.
6

Sign and share

Signing is gasless — Speculate covers every network fee. Once you sign, you get a shareable invite link to send however you want.

Rules of the road

  • 24-hour accept window. If a challenge isn’t accepted within 24 hours, it expires and refunds automatically — nobody’s money sits in limbo.
  • 5 pending duels, max. You can have at most 5 unaccepted duels outstanding at once. Clear one out — or wait for it to expire — before creating another.
  • Cancel before they join, refund in full. You can cancel your own duel any time before an opponent joins and get every dollar back. Once they join, the duel is live — no cancelling out.
  • Directed challenges are private. A challenge aimed at a specific friend only shows up in their Invites tab — it isn’t broadcast to anyone else.
Want the settlement details — ties, no-shows, how a winner is actually decided? That’s all on Duel rules.
