constructor(address _cToken, address _underlying, address _oracle) (public)
getPrice() (external)
setExpiryPriceInOracle(uint256 _expiryTimestamp) (external)
_underlyingPriceToCtokenPrice(uint256 _underlyingPrice) (internal)

Function `constructor(address _cToken, address _underlying, address _oracle) public`

Parameters:

_cToken: cToken asset
_underlying: underlying asset for this cToken
_oracle: Opyn Oracle contract address

Function `getPrice() → uint256 external`

get the live price for the asset

Return Values:

Function `setExpiryPriceInOracle(uint256 _expiryTimestamp) external`

set the expiry price in the oracle

requires that the underlying price has been set before setting a cToken price

Parameters:

_expiryTimestamp: expiry to set a price for

Function `_underlyingPriceToCtokenPrice(uint256 _underlyingPrice) → uint256 internal`

convert underlying price to cToken price with the cToken to underlying exchange rate

Parameters:

_underlyingPrice: price of 1 underlying token (ie 1e6 USDC, 1e18 WETH) in USD, scaled by 1e8
