# Oracles

### afiUSD Oracle - 

The **afiUSD Oracle** exposes a **Chainlink-compatible afiUSD / USD price feed**.

It derives price from:

* afiUSD vault exchange rate (`IafiUSD.exchangeRate()` – 6 decimals)
* Chainlink USDC / USD feed

The oracle implements standard Chainlink interfaces, enabling **drop-in use wherever a Chainlink feed is expected**.

#### Interface

* `decimals()` → 8
* `latestAnswer()` → afiUSD / USD price
* `latestRoundData()` → Chainlink-style round data

#### Helpers

* `getUSDCPrice()` → USDC / USD from Chainlink
* `getCurrentExchangeRate()` → afiUSD vault exchange rate

#### Usage

```solidity
int256 price = afiOracle.latestAnswer(); // afiUSD / USD (8 decimals)
```
