MIP10c9: Subproposal to whitelist Kyber’s PT pricing contract for ETH/USD Oracle Access
MIP10c9-SP#: 11 Author(s): Desmond Ho, Anton Buenavista Contributors: Desmond Ho, Anton Buenavista Status: Formal Submission Date Proposed: 2020-09-16 Date Ratified: <yyyy-mm-dd>
MIP10 is meant to handle all of the Oracle related actions. Unfortunately MIP10 has inconsistencies and doesn’t conform to the monthly governance cadence that the Maker Improvement Proposal framework is built around. This has generated a backlog of Oracle proposals. While MIP10 is refactored to conform to the regular MIP process, Oracle proposals such as this one will utilize the more liberal weekly governance cycle. While strictly speaking this makes them not subproposals, they are included in the subproposal archive as a point of provenance to serve as a paper trail.
KyberSwap has a Promo Token, facilitated by Kyber Network, that is used at hackathons and conferences to promote usage of its platform. 1 PT token is pegged to approximately 1 USD, and is priced against ETH. Hence, the v1 medianizer suited its purpose well and was used.

For each customer address to be whitelisted:
- Is the contract source code verified on etherscan? yes
- Is the Oracle data used in a permissioned manner that would prevent parasitic behavior? yes
- Is Oracle data written to storage? no
- If Oracle data is stored, is it stored in a private variable? no
- If Oracle data is stored, is the value accessible on-chain exclusively by the protocol? no
In accordance with the Responsible Oracle Migration Proposal, fees are waived for the first year and determined by MKR Governance after that.
