Contract types

Six template families, each with a payoff shape, editable parameters, and a canonical settlement schema. All six have been end-to-end traded through the wire and are shipped in the terminal's template library.

spot1 · Spot

The simplest instrument. Buy or sell N units of an asset at price P for value date D.

• Fields — und (underlying), side (buy/sell), qty, price, value_date
• Payoff — linear. Slope = ±qty.
• Settlement — deliver-vs-payment on value date, on-chain or bilateral.
• Use — outright FX, spot metals, stablecoin swaps.

collar1 · Collar

Bought floor, sold cap, zero-cost or paid premium. Bounded downside, capped upside.

• Fields — und, mode (zero-cost or premium), floor, cap, qty, prem, exp
• Payoff — flat below floor, linear between, flat above cap.
• Settlement — cash-settled at expiry against reference fix. Deployed onchain contract: CollarDealV2 (Polygon/Base).
• Use — hedging a long spot position, corporate FX collar.

digital1 · Digital

Binary. Pays out fixed amount if spot ≥ strike at expiry, else nothing.

• Fields — und, strike, payout, prem, exp
• Payoff — step at strike, height = payout.
• Settlement — one-shot cash payment on the fix.
• Use — event bets, threshold hedges, structured note components.

spread1 · Spread

Buy call at K1, sell call at K2 (K2 > K1). Bull call spread.

• Fields — und, k1, k2, qty, prem, exp
• Payoff — flat below K1, linear between K1 and K2, flat above K2.
• Settlement — cash-settled at expiry.
• Use — bounded bullish view, cheaper than outright long call.

straddle1 · Straddle

Long call + long put at same strike. Vol play.

• Fields — und, strike, qty, prem, exp
• Payoff — V-shape centred on strike. Profit if spot moves either way beyond premium.
• Settlement — cash-settled at expiry against ATM fix.
• Use — pre-event vol trades, tail risk exposure.

butterfly1 · Butterfly

Long K1 call + short 2× K2 call + long K3 call (K2 = midpoint). Pinned view.

• Fields — und, k1, k2, k3, qty, prem, exp
• Payoff — tent centred on K2. Max profit if spot pins at K2.
• Settlement — cash-settled at expiry.
• Use — high-conviction pin, low-cost gamma-neutral position.

Templates

The template library ships with one trade-verified example per type. Loading a template hydrates the builder with tested parameters. The green "TRADED" badge and transcript ID (tid) prove the template has actually cleared the wire end-to-end.
