Short-dated
digital options.

Strike lists cash-settled digital calls and puts on BTC, ETH and SOL. Each contract asks one question: will the asset settle above the strike at expiry? Premiums are priced between 0 and 1 USDC per $1 payout, and every contract settles automatically against the Pyth price.

How it works

01

Choose a strike

Pick BTC, ETH or SOL and a strike near spot: “Will BTC settle above $X at expiry?”

02

Buy a Call or Put

A digital call pays $1 if settlement is above the strike; a digital put pays $1 if it is at or below. Pay the premium in USDC; your maximum loss is that premium.

03

Auto-settle at expiry

At expiry the Pyth settlement price is read on-chain. In-the-money contracts are cash-settled at $1 each in USDC; out-of-the-money premium stays in the pool.

Pyth settlement price

Each series references the Pyth price for its underlying at the expiry timestamp.

Cash-settled in USDC

No delivery of the underlying. ITM contracts pay $1.00 USDC each; OTM contracts expire worthless.

Automatic

Contracts auto-settle at expiry. No exercise step, no claim deadline.

Collateral: USDC · Oracle: Pyth · Protocol fee: 1% to the protocol fee wallet

Risk note

Digital options are high-risk. A contract that expires out of the money pays nothing, so you lose the full premium. Short expiries move fast, and oracle, smart-contract and network risks apply. Strike is not live; nothing here is an offer, a quote or financial advice. Check the rules in your jurisdiction.
