The Binary Prediction example lets a user stake SPL tokens on an up/down price move. It reads a MagicBlock pricing-oracle feed on the ER, snapshots the entry price, and settles after the bet expires.
This is an integration example, not a production risk engine. The pool acts as the counterparty without hedging its exposure and uses deliberately simple liquidity accounting.

What the example demonstrates

  • Session-authorized execution: place bets without repeated wallet prompts after setup.
  • SPL-token custody: stake and pool liquidity move through delegated eATAs.
  • Real-time pricing: opening and settlement prices come from the same configured oracle feed.
  • Expiry settlement: wins pay the configured multiplier, ties refund, and losses remain in the pool.
