Interest Rate Oracle Consumer Contracts #38

Closed mikedeshazer closed 4 years ago

mikedeshazer commented 4 years ago

Recently, there was a post regarding grabbing interest rate data from various smart contracts (dydx, Compound, Fulcrum): https://medium.com/iearn/how-we-built-on-chain-apr-for-ethereum-defi-a8d84b680758

Here is an example of a random number generator oracle that is in the proper format to be an OrFeed-compatible oracle: https://github.com/ProofSuite/OrFeed/blob/master/contracts/examples/ProvideDataExamples/randomNumberOracleExample.sol

We are interested in adding an orfeed-compatible oracle into our oracle registry that allows people to use the getExchangeRate method, providing the "Platform-Side" (Borrow or Lend) as the venue param (e.g. "Fulcrum-borrow", "dxdy-lend"), the currency symbol or ethereum address (as string) as the fromSymbol param, and the amount (ignoring the toSymbol parameter) to return the 1 year return at a given rate. For example, 1000 DAI at an interest rate of 5% would return 50. Ideally, it will use OrFeed data to convert the symbol to a token address using OrFeed's getTokenAddress method.

I've been studying the OrFeed API since the last issue on the random number generator, and I think I have a pretty good grasp on how to implement this by now. This is just a matter of knowing which API to call, and what functions to implement.
