When a lender deposits assets into a Feeder Pool or Master Pool they immediately start earning MST. The rate at which a lender earns MST is dependent on the Reward Scale in Feeder Pool or Master Pool they have deposited into.
MoneySwitch sets a specific number of MST to be released per second. This number is used to calculate the total number of MST tokens that should be released in a given period. This number can be updated by MoneySwitch.
The distribution of tokens amongst Feeder Pool(s) and the Master Pool is dependent on the Reward Scale of the Feeder Pool or Master Pool. The higher the Reward Scale the greater the rate at which that pool earns MST.
Typically, as Feeder Pool(s) have a lower risk and reward level relative to the Master Pool, the Reward Scale is equivalently lower.
