FSM Wrapper

Wrapper for FSM-like contracts

1. Summary

The FSMWrapper is meant to act as a funding source for FSM-like contracts as well as an interface that allows other contracts to read data from the FSM integrated with the wrapper.

2. Contract Variables & Functions

Variables
  • authorizedAccounts[usr: address] - addAuthorization/removeAuthorization - auth mechanisms
  • lastReimburseTime - last timestamp when the wrapper sent stability fee rewards to the address that called fsm.updateResult()
  • reimburseDelay - enforced delay between consecutive renumerateCaller calls
  • fsm - the FSM contract that's being wrapped; this contract is the only allowed caller for renumerateCaller
Functions
  • modifyParameters - modify contract parameters
  • renumerateCaller(feeReceiver: address) - called by the fsm in order to send stability fees from the StabilityFeeTreasury to the feeReceiver
  • stopped() public view returns (uint256) - read and return stopped from the fsm
  • priceSource() public view returns (address) - read and return priceSource from the fsm
  • updateDelay() public view returns (uint16) - read and return updateDelay from the fsm
  • lastUpdateTime() public view returns (uint64) - read and return lastUpdateTime from the fsm
  • newPriceDeviation() public view returns (uint256) - read and return the newPriceDeviation from the fsm
  • passedDelay() public view returns (bool) - read and return passedDelay from the fsm
  • getNextBoundedPrice() public view returns (uint128) - read and return the value calculated by getNextBoundedPrice from the fsm
  • getNextPriceLowerBound() public view returns (uint128) - read and return the value calculated by getNextPriceLowerBound from the fsm
  • getNextPriceUpperBound() public view returns (uint128) - read and return the value calculated by getNextPriceUpperBound from the fsm
  • getResultWithValidity() external view returns (uint256, bool) - read and return the current result and its validity from the fsm
  • getNextResultWithValidity() external view returns (uint256, bool) - read and return the next result and its validity from the fsm
  • read() external view returns (uint256) - read and return (or revert) the current result from the fsm

3. Walkthrough

Anyone can read values from the fsm contract by calling the wrapper view functions. The fsm contract is allowed to call renumerateCaller and thus send stability fee rewards to an address.
