Medianizer
Oracle component that fetches the price of an asset
There are five types of medianizers that can be used in GEB:
- 1.
DSValue- used when deploying the system on a localchain or a testnet in order to easily manipulate the price feed of a collateral type / system coin. - 2.
GovernanceLedPriceFeedMedianizer- offers more security by requiring aquorumof oracles to submit their prices which are then medianized on-chain. - 3.
ChainlinkPriceFeedMedianizer- relies on a Chainlink aggregator in order to fetch and push price feeds in to the system. - 4.
UniswapConsecutiveSlotsPriceFeedMedianizer- computes the average price for an asset in the lastmseconds and can be connected to aGovernanceLedPriceFeedMedianizerorChainlinkPriceFeedmedianizer in order to translate the asset's price (e.g use the WETH/WBTC pool to get the price of WBTC in terms of WETH) in a different currency (e.g translate the WBTC/WETH Uniswap pool price into USD).
