Lighter Set to Add Binary Options Support to Its ZK Prover
Lighter's prover repository just got a "Binary options support" commit.
Litscan creator Ungus flagged a newly spotted commit in Lighter's prover repo over the weekend showing that the platform is building out support for binary outcome (i.e. prediction) markets.
It's a clear sign that Lighter, already a top-tier ZK perp venue with deep Robinhood distribution, is about to plant a flag in crypto's intensifying prediction market wars.

What’s the Scoop?
The find: In a Sept. 20 thread, Ungus walked through a commit titled "Binary options support," noting it's circuit-level code rather than a shipped product, meaning no live markets or launch date exist yet.

Mechanics: Per the code, markets are fully collateralized in USDC with no leverage or liquidations, trade on a 0-to-100 scale, and settle at either endpoint once resolved.
Unique twist: The circuit also allows for scalar settlement, where a market can pay out anywhere across the range instead of a flat yes-or-no, opening the door to things like a no-liquidation bet on where a pre-IPO valuation lands inside a floor-and-cap band.
Who's allowed: Markets are created, managed, and resolved by whitelisted operators, which is a narrower, more curated version of the "anyone can post a bond" model Hyperliquid uses for its HIP-3 builder-deployed markets.
The bigger picture: This advance lands amid a broader collapse of the line between perp DEXs and prediction markets. Polymarket recently launched a leveraged perps arm, Hyperliquid shipped HIP-4 event contracts, and Kalshi has pushed into onshore perps. Lighter joining in gives it a shot at capturing that flow inside an exchange that already carries Robinhood Wallet users and lists pre-IPO/RWA products.
