uFragments & uFragmentsSupply use OZ Proxy + Logic, implementation can be upgraded by DAO.
Every other contract in the Digg system can be changed via admin function, ultimately starting from these two contracts.
Changed in uFragmentsSupply:
- MarketOracle
- CPIOracle
- Orchestrator
Each oracle can set it's data sources via admin function.
The Geysers are not upgradable, this is the intent of the system - it's a promise of releasing tokens over time according to the preset schedule.
