Update: The Road to Multi-Collateral Dai—Kovan Release v0.2.4
April 24, 2019
Introduction
Two weeks ago (April 10), we announced the release of MCD v0.2.3 on the Kovan testnet. That release, which included updates to the MCD Core Contracts, the CDP Portal, Dai.js, and the deployment of the Governance Process, was met with great response from the community. Thank you to everyone who tested and provided feedback. As we progress, the Foundation’s goal is to be as transparent as possible with the community and consistently clarify the scope of releases.
For context around MCD as a decentralized system that will operate in an autonomous way once deployed onto the blockchain, see the original The Road to Multi-Collateral Dai post.
Today, we are releasing the third and most recent update, MCD 0.2.4, on the Kovan testnet. This release covers the newest development updates within:
MCD CDP Portal
Dai.js
