# Dynamic Emissions

The amount of `SHERP` / `mSHERP` emitted for stakers and protocol users' rewards is determined by a responsive mechanism. This incorporates a programmatic formula which takes protocol fees, volume, and general market sentiment into account to determine an optimal yield rate for the given epoch. In doing so protocol sustainability and `SHERP` health is preserved.

Epochs occur in weekly intervals. They begin at Monday 00:00:00 UTC and conclude at Sunday 23:59:59UTC. These epoch are concurrent with those used for [Yield Channeling](https://docs.sherpa.trade/docs/yield-channeling).

There is a secondary dynamic emission mechanic that additionally applies to active Positions rewards. This is determined by [Yield Channeling](https://docs.sherpa.trade/docs/yield-channeling).
