The vault
A 15% APR on stablecoins, credited on-chain every day.
The idea
Perpetual futures never expire, so they carry a small recurring payment that keeps their price near the real asset's price. It is called funding, and it flows between two groups: the traders betting an asset will rise, and the traders betting it will fall. Whichever side is more crowded pays the other.
That is a steady income if you can sit on the collecting side without taking a bet on price. So the vault takes both sides at once: a long and a short of the same asset, in equal size. One gains what the other loses, and the price stops mattering. What is left is the funding.
Long and short at once, so direction drops out, is what delta-neutral means.
What you get
15% APR, credited to the vault on-chain daily. The rate is set by us and reviewed as market conditions change.
The credits land in the vault and are reflected in the share price, which is published.
