THE MECHANISM

Simple to enter.
Precise to settle.

HighLow turns a familiar question into a transparent onchain event. Your position is about direction, not a promised dollar payout.

01

Find the anchor

At the start of a round, the first canonical FTSOv2 observation becomes the opening price. Every later observation is measured against it.

02

Choose a side

Buy HIGHER if you expect the close above the anchor. Buy LOWER if you expect it below. Quotes are shown in native C2FLR.

03

Share the pool

At the live close, the winning side shares the pool. Winners claim their proportional settlement on Flare.

100-SECOND MARKET / 120-SECOND CADENCE

Every second has a job.

The directional market ends at 100 seconds. Oracle close and next-round registration complete the on-time cadence.

NO BLACK BOX

The chart is a record, not a forecast.

Prices arrive from FTSOv2 as canonical block observations supplied by the HighLow backend. The interface may draw a smooth line for readability, but settlement only uses observed values.

Opening price is the only anchor. Everything else is an observation.

FLARE-NATIVE BY DESIGN

Built for the chain
that settles it.

HighLow uses the primitives that make short-horizon markets legible: native C2FLR, browser wallets, WalletConnect, and FTSOv2 on Coston2.

A MEASURED PATH FORWARD

BTC first.
A market network next.

HighLow is deliberately narrow today: one BTC/USD feed, one 100-second directional market, and native C2FLR on Coston2. Expansion follows reliability, security, and demonstrated product demand.
