Simple Summary
Remove all centralized oracle code from Synthetix contracts and testing.
Abstract
Remove from the ExchangeRates contract: oracle, currentRoundForRate, updateRates, setOracle', deleteRate`.
Motivation
Once SIP-36 and SIP-75 have been implemented, the centralized Synthetix oracle is no longer being used. In order to decentralize even more, this SIP proposes to remove the power of a centralized oracle to update rates.
Specification
Overview
updateRates and setOracle are to be removed from the ExchangeRates contract. This will mean that only decentralized Agggregator price feeds can be used in the future. This includes all synths, SNX, ETH, etc. This also includes all testnets.
Rationale
The centralized oracle code is currently alongside the decentralized code in ExchangeRates. This SIP simply proposes removing the former altogether.
Technical Specification
- Remove
ExchangeRates.oracle - Remove
ExchangeRates.currentRoundForRate - Remove
ExchangeRates.updateRates() - Remove
ExchangeRates.deleteRate() - Remove
ExchangeRates.setOracle()
Test Cases
N/A.
