requiredBacking
Minimum gross USDC the market must hold to stay solvent at this snapshot.

Parameters
snapshot
- Type:
MarketSnapshot
Needs engine, actualSupply, curveSupply, floorPriceWad.

Tips
- Area is taken up, floor value of curve supply down, floor liability of actual supply up. That is the conservative triple.
