HOW TO MANAGE YOUR
MAKERDAO CDP USING
THE EAC
13
REFRESHER
MakerDAO and ChronoLogic hosted a joint livestream last month.
During and after the call, developers from both team started to work
together on a blog post.
How can you use the EAC with the MakerDAO debt system that underlies
the DAI stablecoin?
14
USE CASE #1 - SAVING IN DANGER CDP
The underlying asset of your CDP (ether) is volatile, you may be liquidate at
short notice.
You want to set up a trustless recurring check which will send more reserve
asset if the risk of liquidation goes too high.
Use a smart contract to wrap over scheduling and create a list of scheduled
transactions in a whitelist.
These transactions will do a routine check for the collateral level of your CDP
and recursively schedule a new call if it is still safe.
15
USE CASE #2 - ROUTINE DAI PAYMENT
You want to set up a routine payment using the DAI stablecoin.
For example, let’s say you want to pay down your debt on a CDP you have
open.
Similar to the last case, you deploy a wrapper contract which will recursively
schedule itself and send these payments every interval.
Will repay your debt over time, or can send a recurring payment somewhere
else.
Funds only need to be available at the exact moment, so don’t need to have
all of them up front.
