4.1 Concept & Rationale

The Futbol Brawl Exchange is a lightweight orderbook-style escrow (not an AMM). Players sell CASH at a fixed price per 1 GOAL; buyers pay GOAL to receive CASH. The contract holds CASH in escrow (via the Bank contract) and performs best-price, FIFO matching.

Why this model?

• Simple mental model: fixed prices (quantized by ticks) rather than curves.

• Real liquidity: sellers are paid immediately on fill (no pending claims).

• Good UX: buyers set a minimum CASH out (slippage guard) and get the best available price.

• GOAL utility: every CASH purchase requires GOAL → direct demand for the token.

How this strengthens GOAL

• Direct utility: every CASH purchase requires GOAL.

• Predictable pricing: ticks make “what you pay in GOAL” clear and auditable.

• Deep 1:1 liquidity (treasury/Bank) onboards users without slippage headaches, building trust and volume around GOAL.
