# Prime Cash Markets

# Fetch the Prime Cash and Prime debt addresses for a given currencyId

pCashAddress = notional.pCashAddress(currrencyId)

pDebtAddress = notional.pDebtAddress(currrencyId)

from brownie.network.state import Chain

chain = Chain()

primeFactors = notional.getPrimeFactorsStored(currencyId, chain.time())

totalPrimeSupply = primeFactors['factors']["totalPrimeSupply"]/1e8

totalPrimeDebt = primeFactors['factors']["totalPrimeDebt"]/1e8

In order to convert Prime Cash to underlying we need to use the underlyingScalar and the supplyScalar. To convert Prime Debt to underlying we need to use the underlyingScalar and the debtScalar:

from brownie.network.state import Chain

chain = Chain()

primeFactors = notional.getPrimeFactorsStored(currencyId, chain.time())

totalPrimeSupply = primeFactors['factors']["totalPrimeSupply"]/1e8

totalPrimeDebt = primeFactors['factors']["totalPrimeDebt"]/1e8

supplyScalar = primeFactors["factors"]["supplyScalar"]/1e18

debtScalar = primeFactors["factors"]["debtScalar"]/1e18

underlyingScalar = primeFactors["factors"]["underlyingScalar"]/1e18

# Total Prime Supply in underlying

totalPrimeSupplyInUnderlying = totalPrimeSupply * underlyingScalar * supplyScalar

totalPrimeDebtInUnderlying = totalPrimeDebt * underlyingScalar * debtScalar

Prime Cash Market utilization is defined as a market's

`debt / supply `

in underlying terms:from brownie.network.state import Chain

chain = Chain()

primeFactors = notional.getPrimeFactorsStored(currencyId, chain.time())

totalPrimeSupply = primeFactors["factors"]["totalPrimeSupply"]

totalPrimeDebt = primeFactors["factors"]["totalPrimeDebt"]

supplyScalar = primeFactors["factors"]["supplyScalar"]

debtScalar = primeFactors["factors"]["debtScalar"]

# Utilization is calculated in underlying terms.

# Utilization = accruedDebtUnderlying / accruedSupplyUnderlying

# Utilization = (totalPrimeDebt * underlyingScalar * debtScalar) / (totalPrimeSupply * underlyingScalar * supplyScalar)

# Note that the underlyingScalar cancels out in both numerator and denominator

utilization = (totalPrimeDebt * debtScalar) / (totalPrimeSupply * supplyScalar)

from brownie.network.state import Chain

chain = Chain()

primeFactors = notional.getPrimeFactors(currencyId, chain.time())

# Prime Cash Supply Rate

oracleSupplyRate = primeFactors["primeRate"]["oracleSupplyRate"]/1e9

# Prime Cash Borrow Rate
