3/// Compound (COMP)
4///
5/// Compound is a decentralized finance (DeFi) protocol that allows users to

7/// The COMP token is the governance token of the Compound protocol.

11/// ```
12/// use typed_money::{Amount, Currency, COMP};
13///
14/// let amount = Amount::<COMP>::from_major(10);
15/// assert_eq!(amount.to_major_floor(), 10);
16/// assert_eq!(COMP::CODE, "COMP");
17/// assert_eq!(COMP::SYMBOL, "COMP");
