The withdrawCarry() function always reverts because of an incorrect assumption.

Lines of code Vulnerability details Impact The Compound protocol's CTokens have 8 decimal places, but the team mistakenly believed that cNote also had only 8 decimal places. However, it was discovered that cNote actually has 18 decimal places. This discrepancy caused the withdrawCarry function to...
