Smart contracts need to act upon asset prices in real-time. Chainlink Price Feeds are used to enable smart contracts to retrieve the latest pricing data of an asset in a single call. These Data Feeds are aggregated from many data sources and published on-chain. Hundred Finance consumes those price feeds to price assets in real-time.
Price feeds are denominated with 8 decimals and update either once in a Heartbeat period or when deviation between last and current price crosses the deviation mark.
Below are the parameters used for all assets available on Hundred Finance's deployed chains.
