Hold through the lockup.Fill before the deadline.
Set your price once. Holdfill converts your SpaceX PreStocks into SPCXx when the pool pays it, never below your terms and never after 12 Mar 2027.
PreStocks are unavailable in the U.S. and to U.S. persons. Issuer eligibility terms.
One signature. Your terms. The program enforces them.
Approve
Pick an amount and the largest gap you accept. One signature approves the order program for that amount only. Revoke anytime.
Wait
Your tokens stay in your wallet. A keeper checks the pool every 10 seconds and does nothing until the price meets your terms.
Fill
When the pool pays your minimum, the program swaps and checks that you received at least that much. From your fallback date, your floor applies.
The pool pays less than the entitlement.By a different amount every day.
