The world of decentralized finance (DeFi) took a significant leap forward on November 18, 2019, when MakerDAO launched the Multi-Collateral Dai (MCD) system. This pivotal upgrade marked a major evolution in the stability, scalability, and utility of the Dai stablecoin — one of the foundational assets in the Ethereum ecosystem. The transition wasn't just technical; it also introduced new terminology, improved risk management, and expanded access to decentralized lending and borrowing.
This article explores the significance of the Multi-Collateral Dai release, its impact on the Maker (MKR) token, and why it remains a cornerstone event in DeFi history.
What Is Multi-Collateral Dai (MCD)?
Multi-Collateral Dai (MCD) is an upgrade to the original Single-Collateral Dai (SCD) system. While SCD only allowed Ethereum (ETH) to be used as collateral for generating Dai, MCD opened the door for multiple types of digital assets to back the stablecoin. This diversification significantly reduced systemic risk and increased capital efficiency across the Maker Protocol.
With MCD, users can lock supported crypto assets in smart contracts known as Vaults — replacing the older term "Collateralized Debt Positions (CDPs)" — to generate Dai, a decentralized stablecoin soft-pegged to the US dollar.

Key Changes Introduced by MCD
1. Multiple Collateral Types
For the first time, assets beyond ETH — such as BAT, WBTC, and USDC — became eligible as collateral. This flexibility allowed more participants to engage with the protocol and reduced reliance on a single volatile asset.
2. New Terminology: From CDPs to Vaults
To reflect broader functionality, MakerDAO rebranded CDPs as Vaults. This change wasn't just cosmetic — it signaled a shift toward a more modular and extensible financial framework capable of supporting complex DeFi products.
3. Dai Savings Rate (DSR)
One of the most innovative features introduced with MCD was the Dai Savings Rate. This mechanism allows Dai holders to earn interest directly on their holdings by depositing them into a smart contract, effectively turning Dai into an interest-bearing currency.
4. Improved Governance and Risk Parameters
The MCD launch empowered MKR token holders with enhanced governance capabilities. They could now vote on critical parameters like stability fees, debt ceilings, and new collateral onboarding — reinforcing the decentralized nature of the protocol.
Impact on MKR Token
The release of MCD had a profound effect on the value and utility of the Maker (MKR) token. As the governance and utility token of the MakerDAO ecosystem, MKR plays several vital roles:
- Governance Voting: MKR holders decide key protocol upgrades and risk settings.
- Protocol Surplus and Auctions: When loans are repaid with stability fees, excess value is converted into MKR and auctioned off, reducing supply and potentially increasing scarcity.
- Emergency Shutdown Mechanism: In extreme scenarios, MKR holders can trigger an emergency shutdown to protect user funds.
Following the announcement and successful deployment of MCD, MKR experienced substantial price momentum. According to historical data, MKR saw a 250.62% increase in value after the event was published — underscoring market confidence in the upgrade’s long-term viability.
Why MCD Was a Game-Changer for DeFi
The introduction of Multi-Collateral Dai didn’t just benefit MakerDAO — it catalyzed growth across the entire DeFi space. By enabling a more robust and diversified collateral base, MCD helped stabilize Dai’s peg during market volatility and encouraged integration with other protocols like Aave, Compound, and Uniswap.
Moreover, MCD laid the groundwork for future innovations such as flash mints, real-world asset (RWA) collateralization, and cross-chain expansion — all of which have since become active development areas within the Maker ecosystem.

Frequently Asked Questions (FAQ)
What is the difference between Single-Collateral Dai and Multi-Collateral Dai?
Single-Collateral Dai (SCD) only accepted Ether (ETH) as collateral, limiting accessibility and increasing systemic risk. Multi-Collateral Dai (MCD) supports multiple approved crypto assets, improving diversification, capital efficiency, and resilience.
How does generating Dai work in the MCD system?
Users deposit supported collateral into a Vault. Once locked, they can generate Dai up to a certain loan-to-value ratio. If the collateral value drops too low, the Vault may be liquidated to maintain system solvency.
What happened to Sai after MCD launched?
Sai was the original name for Single-Collateral Dai. After MCD's launch, Sai remained in circulation temporarily but was gradually phased out in favor of the new multi-collateralized Dai. Users were encouraged to migrate their Sai to Dai through official migration portals.
Can anyone create a Vault?
Yes, anyone with supported collateral can open a Vault via the Oasis Borrow or directly through the Maker Protocol interface. No KYC or permission is required — aligning with DeFi’s core principle of open access.
How does MKR governance work?
MKR holders participate in governance through executive votes and polls conducted on the MakerDAO forum and voting portal. Proposals range from adding new collateral types to adjusting risk parameters and protocol upgrades.
Is Dai truly decentralized?
Dai operates on a decentralized protocol governed by MKR holders. While some components like price oracles rely on centralized feeds temporarily, ongoing efforts aim to fully decentralize these layers over time.
The Legacy of the MCD Launch
Five years on, the Multi-Collateral Dai release is recognized as one of the most important milestones in DeFi history. It demonstrated that stablecoins could evolve beyond simple fiat-backed models into complex, algorithmically managed systems backed by diverse digital assets.
Today, MakerDAO continues to innovate — exploring real-world asset integration, new risk frameworks, and layer-2 scaling solutions. But it all traces back to that critical moment in November 2019 when the DeFi world said goodbye to CDPs and hello to Vaults.
As decentralized finance matures, events like the MCD upgrade serve as blueprints for sustainable innovation — combining technical rigor, community governance, and economic resilience.
Whether you're a developer building on DeFi protocols or an investor navigating digital asset markets, understanding the significance of MCD helps contextualize where decentralized finance has been — and where it’s headed next.
