The veteran Ethereum-based lending protocol Compound has taken a major step forward in its evolution with the announcement of Compound III, also known as Comet. First discussed in January this year, the new protocol version aims to embrace a multi-chain strategy built on EVM (Ethereum Virtual Machine) compatibility, marking a pivotal shift toward broader scalability and capital efficiency. The latest proposal, unveiled on the 16th of this month, is currently under review by the Compound governance community and could go live pending approval.
This upgrade isn’t just an incremental improvement—it’s a reimagining of how decentralized lending can function across chains while maintaining security, simplicity, and user incentives.

What Is Compound III (Comet)?
Compound III, or Comet, is a redesigned lending protocol engineered for EVM-compatible blockchains. Unlike its predecessors, which supported multiple borrowable assets, Comet focuses on a single base asset: USDC—at least in its initial Ethereum deployment. This simplification allows for tighter risk controls and improved capital efficiency.
Users can:
- Deposit supported collateral (e.g., WETH, WBTC) to borrow USDC
- Supply USDC to earn yield
- Participate in governance and potential incentive programs
All interface components will be open-sourced and hosted via IPFS, reinforcing decentralization and enabling community-driven operation. Cross-chain functionality will be managed through Compound Gateway, a dedicated infrastructure layer that links Comet deployments across various EVM-compatible networks.
This modular, chain-agnostic design positions Compound to compete more effectively in the rapidly expanding multi-chain DeFi landscape.
Key Features of Compound III
Built from years of operational experience and community feedback, Compound III introduces several architectural improvements aimed at enhancing security, capital efficiency, and user experience.
1. Single Base Asset Model
By limiting borrowing to one base asset (USDC), the protocol reduces complexity and systemic risk. All other tokens serve solely as collateral, streamlining risk assessment and improving liquidity utilization.
2. Customizable Collateral Caps
Each supported asset has its own supply cap, allowing dynamic control over exposure. This prevents over-reliance on any single collateral type and enhances resilience during market volatility.
3. Advanced Risk Parameters
Comet introduces distinct borrow collateral factors and liquidation collateral factors, giving borrowers more breathing room before liquidation. This granular risk tuning helps avoid premature liquidations and improves user experience during price swings.
4. Redesigned Risk & Liquidation Engine
The new engine strengthens protocol safety without disincentivizing liquidators. It maintains competitive rewards for prompt liquidations while introducing safeguards against manipulation and flash loan attacks.
5. Integration with Chainlink Price Feeds
Instead of relying on proprietary oracles, Comet uses Chainlink’s decentralized price feeds directly. This choice ensures reliable, tamper-resistant pricing across EVM chains and simplifies deployment on new networks. Future oracle changes can be enacted via governance.
6. Decoupled Interest Rate Models
Supply and borrow interest rates now operate under separate models, giving governance full control over monetary policy. This flexibility allows real-time adjustments based on market conditions, demand, and risk tolerance.
7. Enhanced Governance & Management Tools
New administrative interfaces empower governance participants with better visibility and control over protocol parameters, upgrades, and emergency actions—critical for rapid response in decentralized environments.
8. Built-In Incentive Mechanism
A key innovation is the inclusion of an abstracted incentive metric within the core contract. This allows for flexible reward distribution to early adopters and active users—similar to v2’s COMP emissions—but with greater adaptability through governance proposals.
9. Robust Development Framework
The codebase incorporates advanced tooling for testing, auditing, and deployment automation, reducing human error and accelerating safe rollouts across chains.

Current Proposal: Parameter Discussions Underway
As of now, the governance forum is actively debating the initial parameters for the Ethereum mainnet deployment. The proposed collateral assets include:
- WETH
- WBTC
- LINK
- UNI
- COMP
For each asset, specific values are being reviewed:
- Borrow collateral factor
- Liquidation threshold
- Liquidation penalty (fee)
- Supply and borrow interest rate curves
These settings are crucial for balancing accessibility with safety, especially given the high volatility of some assets like LINK and UNI.
Community members are encouraged to participate in discussions on compound.finance/governance, where data dashboards and simulation tools help inform voting decisions.
Why Multi-Chain Expansion Matters
Despite its pioneering role in DeFi lending, Compound has seen its dominance challenged in recent years. According to DeFi Llama, Compound holds $3.03 billion** in total value locked (TVL) on Ethereum, compared to **Aave v2’s $5.41 billion. When including Aave’s deployments across other EVM-compatible chains (like Polygon, Avalanche, and Optimism), its total ecosystem TVL reaches $7.49 billion—a clear indicator of the competitive edge offered by multi-chain presence.
Moreover, token performance reflects shifting market sentiment:
- AAVE has maintained strong growth since late 2020
- COMP, while still valuable, has seen a significant price decline
This context underscores the urgency behind Compound’s push for broader reach. By launching Comet on multiple chains using a standardized, secure framework, Compound aims to reclaim lost ground and attract users seeking stable, USDC-focused lending markets.
Governance Dynamics: Who Decides?
One challenge facing Compound is the concentration of voting power. Current data shows that nearly 50% of governance tokens (COMP) are held by just five major institutional holders. This centralization raises concerns about democratic decision-making and could influence whether the Comet III proposal passes smoothly.
While anyone can submit or vote on governance proposals, meaningful change often requires buy-in from these large stakeholders. The outcome of the Comet III vote may hinge less on community consensus and more on strategic interests among top holders.
Transparency initiatives and delegation programs are underway to broaden participation, but progress remains gradual.
Frequently Asked Questions (FAQ)
Q: What makes Compound III different from previous versions?
A: Compound III simplifies the lending model by focusing on a single base asset (USDC), improves risk management with refined collateral factors, integrates Chainlink oracles directly, and supports multi-chain expansion via EVM compatibility.
Q: Can I borrow any token on Comet?
A: No—only the base asset (initially USDC) can be borrowed. Other tokens like WETH or WBTC serve exclusively as collateral.
Q: How does Comet handle liquidations?
A: It uses a redesigned engine that balances user protection with liquidator incentives. Distinct thresholds prevent premature liquidations while ensuring prompt responses when collateral ratios fall below safe levels.
Q: Will Comet launch on other blockchains?
A: Yes—the design is EVM-compatible, meaning it can deploy on networks like Arbitrum, Optimism, Polygon, Base, and Avalanche once approved and configured.
Q: How are interest rates determined?
A: Supply and borrow rates use separate models that adjust dynamically based on utilization. Governance can modify these curves to optimize yield and risk.
Q: Are there rewards for using Comet?
A: Yes—Comet includes a built-in incentive mechanism that can distribute rewards to early adopters and active users, subject to governance approval.

Final Thoughts
With Compound III (Comet), one of DeFi’s founding protocols is repositioning itself for the next era of decentralized finance—one defined by interoperability, efficiency, and user-centric design. By anchoring its lending model around USDC, embracing EVM-wide deployment, and refining its risk architecture, Compound is laying the groundwork for a resilient comeback.
However, success won’t come from technology alone. Broader governance participation, effective incentive alignment, and trust-building with users will determine whether Comet can truly compete in today’s hyper-competitive DeFi landscape.
As the governance vote unfolds, all eyes will be on how this veteran protocol navigates both technical innovation and community dynamics in pursuit of a decentralized future.
