MKR Roll Call

|\  /| now or
| \/ |  never

What?

• At 16:00 UTC on April 11, 2019, there will be an MKR voter “snapshot” to collect a list of voting addresses.
• You can set your MKR to vote any time before the snapshot, just be sure to leave it there until April 11th, 16:00 UTC (the first block after this timestamp).
• This is optional, but recommended. Consider this the notice to MKR holders that voting has started in earnest. You also get a fun prize:
• You will get to etch a small section of a slab of ASCII art, which will be permanently embedded into the MCD contract.

How?

• Anyone who is voting for any proposals (any non-empty slate) at 2019/4/11 16:00:00 UTC will be counted as present.
• We will manually assemble representative addresses for each voter (for example, if you use the VoteProxy contract, we’ll take it’s “voting key”), then collect signed messages for your section of art.

VoteProxy contract at vote.makerdao.com

You can use the vote.makerdao.com GUI to vote on the current stability fee proposal (the one that ends on April 11th at 16:00 UTC). Just be sure your MKR is locked and voteing until that time.

Direct Voting - Metamask + Hardware Wallet

Redeem your old MKR, if you haven’t already.

There is a GUI available at makerdao.com/redeem

You can use etherscan for the generic redeemer UI, but the old MKR token cannot be verified due to its archaic source code.

If you use the GUI, be sure to still verify the transactions.

1. oldMkr.approve(redeemer, balance);
2. redeemer.redeem(balance);

Voting with Chief

Etherscan Chief GUI

Custom GUI

Whether you use etherscan, or the chief.makerdao GUI, be sure you still verify the generated transactions:

Approve the Chief to spend your MKR (and your “MKR IOU”s, while you’re at it).

1. mkr.approve(chief, max_u256);
2. iou.approve(chief, max_u256);

IOU approval

GOV approval

lock your MKR:

1. chief.lock(balance);

Chief.lock via Etherscan

vote for any roll call slate that includes address 0x0 as a candidate

1. chief.vote(rollCallSlate);

If you don’t have a particular other proposal you want to support, you can use the existing ID for [0x0]

rollCallSlate == 0x290decd9548b62a8d60345a988386fc84ba6bc95484008f6362f93160ef3e563
              == etch([0x0])

you can verify this with chief.slates(rollCallSlate, 0); and chief.slates(rollCallSlate, 1)

Chief.vote via Etherscan

Chief.slates via Etherscan

If you want to change your vote

1. vote(different-slate).

Create a new slate with etch([candidate1, candidate2]), up to 5 candidates. Make sure your list of candidates is lexically ordered and has no repeating candidates, otherwise the contract will reject it.

Chief.vote, Chief.etch via Etherscan

When it comes time to move your MKR

1. chief.free(amount).

Don’t worry about re-voting, everything is automatically adjusted.
