Perpetuals have no expiry
A perp can stand in for a dated hedge, but you pay funding the whole time and only learn your exit price on the day you close.
PerpetualsSetryn is an exchange for risk with a date on it. Enter what you need to buy or sell and when, ask the makers you choose for a firm price, and clear the hedge against native USDC.


Only the makers you invite see the request.
Onchain markets are built for spot swaps and perpetuals. If you know you will receive, pay or unlock tokens on a set date, you are left stitching venues together, trusting an OTC desk, or holding a perp whose cost you can't know in advance.
