 Oracle Provider
================

In several places in the Mero protocol there is a need for on chain price oracles. Most notably for token swaps to get an appropriate ``minAmountOut`` value for slippage protection. Instead of implementing this oracle logic in several places, the Oracle Provider is a contract to expose some useful views for use in the rest of the protocol.

There are two main views exposed by the Oracle Provider:

.. py:function:: OracleProvider.getPriceETH(address baseAsset) external view returns (uint256)

    Quotes the ETH price of ``baseAsset``.

    * ``baseAsset``: The asset of which the price is to be quoted.


.. py:function:: OracleProvider.getPriceUSD(address baseAsset) external view returns (uint256)

    Quotes the USD price of ``baseAsset``.

    * ``baseAsset``: The asset of which the price is to be quoted.
