Tracking earnings on Idle is easy, you just need the avg buy price of the IdleTokens, the amount of IdleTokens held by a user and the current price.
IdleToken contract saves and updates the
userAvgPrices mapping which contains the avg price paid for each IdleToken of a user, so to calculate earnings (in underlying) one can do the following:1
address user = <address_of_user>;
2
IIdleToken idleDAI = IIdleToken(<address_idle_token>);
3
uint256 userBalance = idleDAI.balanceOf(user);
4
uint256 avgCost = userBalance.times(idleDAI.userAvgPrices(user)).div(10**18);
5
uint256 currentValue = userBalance.times(idleDAI.tokenPriceWithFee()).div(10**18);
6
uint256 earnings = currentValue.minus(avgCost);
Copied!
Note:
tokenPriceWithFee is available only for IdleToken of the Best yield strategy. For the Risk adjusted strategy fee must be accounted on the integrators side or by using this helper.
