Pick the coin, the strike and the expiry
The strike is how far above the price at the start of the hour or the day the coin has to go, from +0.5% to +10%. The expiry is the end of the hour or the end of the day, in UTC.
Pick a coin and a strike on the dial. If BONK closes above it at expiry, the call pays you the difference, up to 5% of the size in an hour or 20% in a day. If not, you lose only the premium.
Every call you have bought with this wallet. Open calls settle when their hour or day closes on Binance; a call that ends above its strike is paid to your wallet from the vault within a minute.
| Call | Strike | Strike price | Size | Premium | Expiry (UTC) | Close | Result |

A call option is the right to buy a coin at a fixed price, the strike, until a set time, the expiry. On STRIKE every call is settled in SOL and backed by a vault, a pool of SOL that is locked before the call is sold, so nobody is ever liquidated.
The strike is how far above the price at the start of the hour or the day the coin has to go, from +0.5% to +10%. The expiry is the end of the hour or the end of the day, in UTC.
The premium is the price of the call, sent from your wallet straight to the vault. It is the most you can lose. A strike far away is cheap, a strike close by costs more.
You receive the distance between the closing price and the strike, on the size you bought, up to 5% for an hour and 20% for a day. The vault holds that much back for every call it sells. At or below the strike, the call expires and the vault keeps the premium.
Live prices from Binance, refreshed every ten seconds. The premiums are what a call on 10 SOL of the coin costs on STRIKE: the Black-Scholes value of the capped payout, from how much the coin has moved hour by hour over the last seven days, plus 20% for the vault.

The vault is the other side of every call: it takes in the premium, and pays out when a call ends above its strike. This replays the last seven days of real hourly prices for all six coins above, selling a 1 hour call at +1% every hour at the premium in the table. The three best are shown.
