USH Facilitators

as of 02/01/2025

At its core, USH is an ESDT token owned by the USH Minter Smart Contract. Within this smart contract, Facilitators are defined as accounts that are entitled to mint and burn USH. On the other hand, a Facilitator Pool represents a collection of facilitators that have an associated capacity $C_f$, i.e. the upward limit of what they can mint on certain conditions.

The maximum amount of USH that can be in circulation at any given point in time is the Maximum Supply, given by:

$$S^{\text{USH}}_{\max}(t) = \sum_{f=1}^{F} C_f(t).$$

Each Facilitator Pool has an associated balance given by the amount of USH minted minus the amount of USH burned:

$$U_f (t) = \text{USH}_{\text{minted}} (t) - \text{USH}_{\text{burned}} (t).$$

It is important to know that this last amount might be negative, given that the amount of USH burned can be higher than the amount minted by that Facilitator Pool. At any point in time, the amount of USH that a Facilitator can mint depends on the difference between the balance and capacity of the Facilitator Pool to which it belongs:

$$A^{\text{USH}}_{i \in f}(t) = C_f(t) - U_f.$$

Finally, the Circulating Supply of USH $S$ at any given point in time is given by:

$$S_{\text{USH}}(t) = \sum_{f=1}^{F} U_f(t).$$

Facilitator Pools can be very different in technical nature. However, the first two pools will be given by:

• Hatom’s Lending Protocol, in production since July 2023,
• Hatom’s Isolated Pools, going into production alongside USH launch.
