Glossary/Perpetual futures
Perpetual futures
Perpetual futures (perps) are derivative contracts with no expiration date. Instead of converging at expiry, they use funding payments and mark/index mechanisms so the contract tracks a reference market. They dominate crypto derivatives volume on many venues.
