Executive Summary

If this executive proposal passes, the following changes will occur within the Maker Protocol:

  • The PSM-USDC-A Debt Ceiling will be increased from 3 billion DAI to 4 billion DAI.
  • Multiple changes to Stability Fees, Debt Ceilings, Target Available Debt, and Ceiling Increase Cooldowns will be made to various vault types as described in the Proposal Details section.
  • Auction Parameters for ETH Vault Types will be updated as listed below in the Proposal Details section.
  • The UNIV2DAIUSDC-A Vault Type will have its Liquidation Ratio lowered from 105% to 102% and Stability Fee lowered from 1.0% to 0.5% with liquidations remaining off.

If this executive proposal passes, the following additions will be made to the Maker Protocol:

  • Yearn Finance will be added to the whitelist for the UNIUSD, LINKUSD, AAVEUSD, and COMPUSD Oracles.

Voting for this executive proposal will place your MKR in support of the changes and additions outlined above.

Unless otherwise noted, the changes and additions listed above are subject to the GSM Pause Delay. This means that if this executive proposal passes, the changes and additions listed above will only become active in the Maker Protocol after the GSM Pause Delay has expired. The GSM Pause Delay is currently set to 48 hours.

This executive proposal includes an office-hours modifier that means that it can only be executed between 14:00 and 21:00 UTC, Monday - Friday. This is to ensure that at least some auction keepers are available to react to unforeseen issues with their bots in the event of early liquidations on new collateral types.

If this executive proposal does not pass within 30 days, then it will expire and can no longer have any effect on the Maker Protocol.

Adjusting Auction Parameters for ETH Vault Types

Given the successful outcome of this poll, the following recommendations of the Risk Core Unit will be implemented if this executive proposal passes.

For further information, you may view this thread detailing the Core Unit's recommendations.

Increasing Local Liquidation Limits (ilk.hole)

  • ETH-A Local Liquidation Limit from 22 million DAI to 30 million DAI
  • ETH-B Local Liquidation Limit from 8 million DAI to 15 million DAI
  • ETH-C Local Liquidation Limit from 5 million DAI to 20 million DAI

ETH-B Adjustments

Lowering the UNIV2DAIUSDC-A Liquidation Ratio and Stability Fee

Given the successful outcome of this Signal Request and this subsequent poll, the following changes will be implemented if this executive proposal passes.

Vault Type Changes

  • The Liquidation Ratio for UNIV2DAIUSDC-A will be decreased from 105% to 102%.
  • The Stability Fee for UNIV2DAIUSDC-A will be decreased from 1.0% to 0.5%.

Note: The Oracle Domain Team has decided a 102% Liquidation Ratio will be used instead of the 101% that was favored for this Vault Type, due to the oracle risk of estimating the size of the Uniswap Pool as fees accumulate. The Risk Core Unit has additionally decided that liquidations should remain off for the vault type, at this time. You may view a discussion of these decisions on the Governance and Risk Call for June 10, 2021.

Whitelist Yearn Finance on UNIUSD, LINKUSD, AAVEUSD, COMPUSD Oracles

Given the successful outcome of this poll, Yearn Finance will be added to the UNIUSD, LINKUSD, AAVEUSD, and COMPUSD Oracle Security Module whitelists to read current and queued price data if this executive proposal passes.
