Scalar

What You Can Trade

Binary, spread, range accrual, and one-touch markets on one unified book.

Scalar runs the binary markets every prediction platform offers, plus three more that only continuous settlement makes possible. Same contract, same order book, same $10 max payout. Every market can be traded long (buy) or short (sell); examples show the long side. Payouts and P&L below are per contract, against your entry price.

Binary

Step function at the strike. $0 below the level, $10 at or above, nothing in between.

Binary payoff profile: $0 below the strike, jumping to $10 at or above.

"Will ETH be above $4,000 on July 1?" Buy Yes at $6.50, the market's ~65% implied odds.

  • ETH at $4,200 at expiry → $10.00 (+$3.50)
  • ETH at $3,800 at expiry → $0.00 (−$6.50)

The prediction-market staple, natively onchain.

In traditional finance, this is a binary option (also called a digital option).

Spread

Linear payout between two strikes, capped at both ends. Perps-like exposure without the liquidation risk.

Spread payoff profile: payout ramps linearly from $0 at the lower strike to $10 at the upper strike.

ETH is at $3,000 and you think it'll rise. Buy "ETH $3,000–$4,000" at $3.00, implying a ~30% expected settlement.

  • ETH at $3,000 or below → $0.00 (−$3.00)
  • ETH at $3,500 → $5.00 (+$2.00)
  • ETH at $4,000 or above → $10.00 (+$7.00)

In traditional finance, this is a bull call spread. Same payoff, one position, no options complexity. The short side is a bear put spread — identical structure, opposite view.

Range Accrual

Linear in time: payout ramps with the share of the period spent in range.

Range accrual payoff profile: payout scales linearly from $0 at 0% time in range to $10 at 100%.

You think ETH will stay between $2,800–$3,200 for 30 days. Buy at $4.50, implying ~45% expected time-in-range.

  • In range 100% of the time → $10.00 (+$5.50)
  • In range 50% of the time → $5.00 (+$0.50)
  • In range 0% of the time → $0.00 (−$4.50)

Every second in range counts. Typically only available to institutions through structured products.

In traditional finance, this is a range accrual.

One-Touch

Path-dependent binary: flips to $10 the instant the level is touched, any time before expiry, else $0.

One-touch price paths: a path that touches the barrier pays $10 and can resolve early; a path that misses pays $0.

"Will BTC touch $120,000 before August 1?" Buy Yes at $2.80, a ~28% implied chance.

  • BTC tags $120,000 on day 15 → $10.00 (+$7.20), and the market resolves early
  • BTC peaks at $119,500 → $0.00 (−$2.80)

A bet on volatility and spikes, not on where price ends up.

In traditional finance, this is a one-touch option. Path-dependent: only whether the level was touched matters.
