Chainlink Price Oracle

This repository contains an implementation of the Vault's PriceOracle. The PriceOracle is part of the core architecture and is in charge of providing an interface to rate a token based on another token to the Vault. This can be achieved using any type of on-chain oracle, then this repo provides a simple implementation using Chainlink V3.

Deployment

In order to deploy this smart contract locally you can simply do:

import { deploy } from '@mimic-fi/v1-helpers'

const tokens = [...]
const priceFeeds = [...]
const oracle = await deploy('@mimic-fi/v1-chainlink-price-oracle/artifacts/contracts/ChainlinkPriceOracle.sol/ChainlinkPriceOracle', [tokens, priceFeeds])

Development

In order to use a PriceOracle you can simply do:

import "@mimic-fi/v1-vault/contracts/interfaces/IPriceOracle.sol";

contract MyContract {
  IPriceOracle connector;

  function getTokenPrice(address token, address base)
    external
    returns (uint256)
  {
    return oracle.getTokenPrice(token, base);
  }
}
