Supply Precision
The base unit of the ScPrime coin supply is 24 decimal places or 10^24. A precision change was done early on – Supply Change Guide

ScPrimeFunds
10,000 ScPrimeFunds (SPF) were initially created and distributed to holders of record at the open source software block 179,000.

At block 59550, a hard fork created an additional 20,000 SPF

At block 109,000, a hard fork changed total emission to 200,000,000 and set the tax rate across the entire population at 10%.
A number of units have been given away to various entities including the angel investors in SCP, Corp. There can be no further negligible change to the supply without significant consensus from a number of parties. 200m is considered the final emission.
