Introduction
The decentralized finance (DeFi) lending landscape continues to evolve rapidly, with Compound III emerging as a significant upgrade to its predecessor. This article explores the key features of Compound III and includes an exclusive interview with Jared Flatow, VP of Engineering at Compound Labs, providing insights into the protocol's innovative design and multi-chain strategy.
Compound III Overview
Key Innovations in Compound III
Single Base Asset Markets
- Each market supports only one borrowable asset (e.g., USDC).
- Other assets serve as collateral with customized risk parameters.
- Clear separation between lenders (earning yield) and borrowers (paying interest).
Dual Collateral Factors
- Borrow Collateral Factor (BCF): Maximum loan-to-value ratio.
- Liquidation Collateral Factor (LCF): Threshold triggering liquidation.
- LCF > BCF creates a buffer zone for debt repayment before liquidation.
Supply Caps
- Governance-controlled limits per asset class mitigate risk.
- Enables safer deployment on L2s and alternative chains.
Enhanced Liquidation Mechanism
Two-phase process:
- Debt absorption by protocol reserves.
- Discounted collateral auctions when reserves reach thresholds.
- Reduces immediate DEX liquidity dependency.

Exclusive Interview with Jared Flatow
Q1: What drives Compound's multi-chain strategy despite market challenges?
"Comet's lean, auditable contracts are designed for secure cross-chain deployment. While Ethereum remains our priority, we must serve users seeking affordable alternatives without compromising security."
Q2: How does the Business Source License (BSL) impact community deployments?
"BSL gives governance flexibility—communities can fork independently or contribute back. We're focused on demonstrating secure deployments first before expanding permissions."
Q3: Why single borrowable assets with multiple collaterals?
"This design isolates price risk to specific assets while maintaining composability. Managers can set per-collateral caps, giving lenders better risk control than V2's pooled approach."
Q4: Explain Comet's liquidation improvements.
"Our phased approach separates debt resolution from asset sales. Reserves act as a backstop, while discounted auctions incentivize liquidators—reducing systemic risk during volatility."

Comparative Analysis
| Feature | Compound V2 | Compound III |
|---|---|---|
| Assets | Multi-asset pools | Single borrow asset |

FAQs
What chains will support Compound III first?
Ethereum mainnet remains the priority, with Optimism and Arbitrum deployments planned for Q3 2023.
How do supply caps protect lenders?
Caps prevent overexposure to any single collateral type, especially important for higher-risk assets on L2s.
Can I still earn interest on supplied collateral?
No—only the base asset generates yield. Collateral solely secures borrowing capacity.
Is Gateway still part of Compound's roadmap?
Gateway development is paused as the team focuses on Comet deployments. Future integration possibilities remain open.
Conclusion
Compound III represents a strategic evolution in DeFi lending infrastructure, balancing capital efficiency with enhanced risk controls. Its modular design and multi-chain approach position it for sustainable growth across emerging blockchain ecosystems.
