Interest Model

Borrow interest rates can be queried with GetBorrowRate, GetBorrowRates or GetAllBorrowRates.

Lend interest rates can be queried with GetAllLendingRates.

GetAllAssets can be used to get each asset market state and the param internals for in-depth analysis.

Note: The borrow rate returns a "simple" borrow rate, quantified yearly. From this rate, the borrow annual percentage rate (APR) can be calculated as borrow_apr = e^(borrow_rate + 1) - 1.

Query Response

The return from the query may include an AssetMap using Vec Key-Value pairs where the Keys are AssetInfo as shown below in these Common Structures.

AssetMap

RUST

pub type AssetMap<T> = NeptuneMap<AssetInfo, T>;

pub struct NeptuneMap<K, V>(pub Vec<(K, V)>);

AssetInfo

RUST

pub enum AssetInfo {
    Token { contract_addr: Addr },
    NativeToken { denom: String },
}
