Your calls, and every call on offer

Exercise what you hold, withdraw premiums, cancel what has not sold.

First release. Real money on Base: your own funds, at most $50 of stock per option. Calls run as Raindex orders owned by the writer's option account (factory 0x0928…a78d). Fully collateralised, fork-tested and independently reviewed; still a first release.

Buyer risks the premium. You pay it once and it is not refunded. If the stock does not go above the strike before expiry, the option is worth nothing and you lose the whole premium. You must exercise yourself, from the same wallet, before expiry.

Writer gives up the upside. Your stock is locked until expiry. If the price goes above the strike, the buyer takes it at the strike and you miss the gain. If the price falls, the loss is still yours; the premium is all you keep.
