If you are new to voting in the Maker Protocol, please see the voting guide to learn how voting works, and this wallet setup guide to set up your wallet to vote.

Executive Summary

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

  • The Liquidations 2.0 Contracts will be authorized.
  • LINK-A will be moved to the Liquidations 2.0 Framework.

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

  • The Emergency Shutdown Threshold will increase from 50,000 MKR to 75,000 MKR.

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.
