The Field is Beanstalk's native credit facility. Anytime Beanstalk is willing to borrow Beans from the market, it issues Soil in the Field. Beans are Sown in exchange for Pods, the Beanstalk-native debt asset. Loans to Beanstalk are issued with a fixed interest rate, known as the Temperature, and an unknown maturity date.
Pods become Harvestable Pods that can be Harvested (redeemed) for 1 Bean each on a First In, First Out (FIFO) basis. There is no penalty for waiting to Harvest Pods.
The Field consists of 2 Facets:
The Barn was built after Beanstalk was exploited on April 17, 2022. The Barn distributes Bean rewards to those who hold Fertilizer tokens from participation in the Barn Raise. It also handles the Chopping of Unripe Beans and Unripe LP into their underlying assets at a potential penalty.
In the Beanstalk ecosystem,
Unfertilized Beans are referred to as Sprouts;
Fertilized Beans are referred to as Rinsable Sprouts that can be Rinsed; and
Underlying assets are referred to as Ripe assets.
Unfertilized Beans become Fertilized Beans that can be claimed (redeemed) for 1 Bean each on a pari passu basis. There is no penalty for waiting to claim Fertilized Beans.
