FluidGenericOracleBase ​

Git Source

Inherits: OracleError, GenericOracleStructs, ChainlinkSourceReader, FluidSourceReader, FluidDebtSourceReader

generic configurable Oracle Base combines up to 4 hops from sources such as

  • an existing IFluidOracle (e.g. ContractRate)
  • Redstone
  • Chainlink
