The decentralized finance (DeFi) ecosystem is set for a transformative update as MakerDAO, the backbone project behind Dai stablecoin, revealed plans to launch Multi-Collateral Dai (MCD) on November 18. This announcement was made during Devcon 5, the fifth Ethereum Developer Conference held in Osaka, Japan.
Why MCD Matters for DeFi
MCD introduces groundbreaking features to the Maker Protocol, significantly expanding its utility:
- Diverse collateral options: Beyond just ETH, users can now leverage multiple asset types to generate Dai.
- Dai Savings Rate (DSR): A built-in interest mechanism allowing Dai holders to earn yields directly within the Maker ecosystem—previously possible only via third-party platforms like Compound or dYdX.
Dual Tools for Dai Stability
With MCD, MakerDAO gains two primary levers to stabilize Dai’s peg to 1 USD:
- Stability Fee: Adjusts borrowing costs for Dai creators.
- DSR: Influences demand by incentivizing holding (via higher rates) or discouraging hoarding (via lower rates).

Key Features of Multi-Collateral Dai
1. Mandatory Upgrade from SCD to MCD
All Single-Collateral Dai (SCD) holders must migrate to MCD post-launch. MakerDAO provides a Migration Guide and a 6-month window to complete the transition.
Consequences of Non-Upgrade:
- Unmigrated Dai loses its 1 USD peg, fluctuating with ETH’s market price.
- DeFi platforms integrating Dai (e.g., lending protocols) will require updates to support MCD.
2. Ecosystem Adaptation
Major DeFi projects like Compound have confirmed:
- Existing SCD markets will remain operational but won’t enforce upgrades.
- New contracts will be deployed for MCD compatibility.
FAQ: Multi-Collateral Dai Explained
Q1: How does DSR benefit Dai holders?
A1: DSR acts as a risk-free savings tool, offering variable interest rates directly from MakerDAO—eliminating reliance on external platforms.
Q2: What collateral types will MCD support initially?
A2: While ETH remains primary, MakerDAO plans to add wrapped BTC (WBTC) and other ERC-20 tokens in phased rollouts.
Q3: Will old Dai (SCD) become worthless after the upgrade?
A3: No, but its value will decouple from USD, trading as a volatile asset tied to ETH’s price.

Strategic Implications for DeFi
- Enhanced Liquidity: More collateral options could attract institutional participants.
- Interest Rate Arbitrage: Traders may exploit discrepancies between DSR and third-platform rates.
- Regulatory Readiness: MCD’s modular design prepares MakerDAO for future compliance requirements.
Pro Tip: Monitor Maker Governance for real-time updates on collateral proposals and rate adjustments.
Final Notes
The MCD rollout marks a pivotal evolution for Dai, reinforcing its role as DeFi’s most decentralized stablecoin. Stakeholders—from holders to developers—must proactively adapt to harness its full potential.
