4.7 Security & Edge Cases

• CEI + Reentrancy guards + Pausability on critical paths.

• DoS-resistant seller payouts:

  • If paying a seller reverts, the listing is delisted on full fill and any remaining CASH is returned; the swap continues (no market lock).

• Iteration limits protect swaps from scanning excessively large books.

• Slippage guard: buyer’s minCashOut ensures atomic consistency.

• GOAL fees: if GOAL is fee-on-transfer, the UI displays net values; sellers receive net at payout.
