Ethereum (ETH): why ETH remains core collateral across DeFi blue chips

Discover why Ethereum continues to be the backbone of collateral for leading DeFi protocols in 2025 and how tokenized real‑world assets like Eden RWA fit into this landscape.

• Ethereum’s dominance as on‑chain collateral remains steady amid rising competition.
• DeFi blue‑chips rely on ETH for liquidity, risk management and network effects.
• Tokenization of real‑world assets offers new diversification while preserving ETH’s central role.

In the rapidly evolving world of decentralized finance (DeFi), collateral selection is a pivotal factor that determines protocol resilience, user confidence, and capital efficiency. Ethereum (ETH) has emerged as the most widely adopted form of collateral for “blue‑chip” DeFi projects—those with high market capitalization, strong liquidity, and a robust developer ecosystem.

While alternative assets such as wrapped Bitcoin (WBTC), stablecoins, or tokenized real‑world assets are gaining traction, ETH remains the core anchor. This article examines the reasons behind Ethereum’s continued dominance, explores how DeFi protocols structure collateralization mechanisms, assesses market impact and risks, and highlights a concrete example of real‑world asset tokenization: Eden RWA.

Readers will learn why Ethereum is still the preferred collateral choice, what factors influence protocol decisions, and how tokenized real‑world assets can complement traditional ETH‑based strategies without diluting its centrality. Whether you’re an intermediate retail investor or a DeFi enthusiast looking to deepen your understanding, this analysis provides actionable insights for 2025 and beyond.

1. The evolving role of Ethereum as DeFi collateral

The concept of collateral in DeFi is simple yet foundational: users lock up an asset to mint a new token or access liquidity, with the locked asset serving as security against potential defaults. In practice, the choice of collateral affects risk profiles, user experience, and protocol economics.

Ethereum’s emergence as the most common collateral can be traced back to several intertwined developments:

• Network effect and liquidity: ETH is the native token of the largest smart‑contract platform. Its deep liquidity on exchanges, staking rewards from Ethereum 2.0, and widespread integration in wallets create a self‑reinforcing loop.
• Staking and yield potential: Staked ETH earns passive rewards (currently around 4–6% APY), making it an attractive store of value for users who wish to earn while providing collateral.
• Cross‑protocol compatibility: Many DeFi protocols—MakerDAO, Aave, Compound, and newer entrants like Lido and Convex—are built on Ethereum or rely heavily on its ecosystem. This interconnectivity encourages a single dominant collateral type.
• Regulatory familiarity: Regulators have been monitoring ETH more closely than other crypto assets, leading to clearer legal frameworks for compliance and risk mitigation.
• Smart contract maturity: Ethereum’s robust tooling (e.g., Solidity, Hardhat, Truffle) and extensive audit history reduce technical risk compared to newer platforms.

The result is a self‑sustaining collateral ecosystem where protocols can leverage ETH’s liquidity, stability, and network effects. This advantage has persisted even as alternative assets have grown in popularity.

2. Mechanics of ETH collateralization in leading protocols

Collateralization on DeFi platforms follows a structured process that balances risk, liquidity, and user incentives. The typical workflow can be broken down into four core steps:

1. Deposit: Users transfer ETH (or wrapped ETH) into a smart‑contract vault, often via a bridging service if the asset originates from another chain.
2. Valuation and over‑collateralization: Protocols calculate the collateral value in USD or a stablecoin equivalent. Over‑collateralization ratios (e.g., 150% for MakerDAO’s DAI) protect lenders against price volatility.
3. Minting or borrowing: Once the deposit meets the required ratio, users can mint synthetic assets (DAI, USDC), borrow other tokens, or access liquidity pools.
4. Liquidation and redemption: If collateral value drops below a threshold, smart contracts trigger liquidation to repay debt. Otherwise, users can redeem their collateral by returning borrowed assets plus interest.

Key actors include:

• Issuers: Protocol developers who design the collateral rules and risk parameters.
• Custodians: Audited smart contracts that hold and manage user funds.
• Governance token holders: Participants who vote on protocol updates, collateral types, and liquidation thresholds.
• Users: Retail or institutional participants who supply ETH and engage with the platform.

The reliance on Ethereum’s infrastructure ensures that these steps are executed deterministically, transparently, and with a proven track record of security.

3. Market impact & use cases

ETH’s dominance as collateral has tangible effects across the DeFi landscape:

• Capital efficiency: High liquidity allows protocols to offer lower borrowing rates and higher APYs, attracting more users and deepening market participation.
• Risk mitigation: Over‑collateralization and automated liquidation mechanisms reduce default risk for lenders, fostering trust among institutional investors.
• Interoperability: Many DeFi protocols share liquidity pools and governance structures built on Ethereum, enabling cross-protocol incentives (e.g., staking rewards shared across Compound and Aave).
• Innovation catalyst: The maturity of Ethereum’s tooling encourages rapid prototyping of new financial instruments—synthetic assets, yield aggregators, and decentralized exchanges.

A practical illustration is the MakerDAO system. Users lock ETH to mint DAI, a stablecoin pegged to USD. The over‑collateralization ratio (currently 150%) ensures that even during sharp price swings, DAI holders remain protected. This structure has proven resilient across multiple market cycles.

These examples illustrate how ETH and its derivatives sustain liquidity, yield generation, and risk management across DeFi’s most influential platforms.

4. Risks, regulation & challenges

Despite its advantages, Ethereum collateralization is not without pitfalls:

• Price volatility: Even with over‑collateralization, rapid price drops can trigger cascading liquidations, especially during market stress.
• Smart contract risk: Bugs or exploits in vault contracts expose user funds. High-profile incidents (e.g., the 2021 Aave hack) underscore this vulnerability.
• Regulatory uncertainty: While ETH is more regulated than many altcoins, evolving frameworks like MiCA (EU) and SEC scrutiny could impose compliance costs or operational restrictions.
• Liquidity risk for derivatives: When users withdraw large amounts of collateral simultaneously, the protocol may need to liquidate positions quickly, potentially impacting market prices.
• Custodial friction: Cross‑chain bridging introduces additional attack vectors (e.g., Wormhole exploit).

Mitigating these risks requires rigorous audits, diversified collateral portfolios, and robust governance structures that can adapt to regulatory changes.

5. Outlook & scenarios for 2025+

The trajectory of ETH as core DeFi collateral depends on several interacting forces:

• Bullish scenario: Continued adoption of Ethereum 2.0 staking, expansion of Layer‑2 scaling (Optimism, Arbitrum), and the integration of tokenized real‑world assets could reinforce ETH’s liquidity position, driving down borrowing costs and attracting institutional capital.
• Bearish scenario: A sudden shift toward other blockchains with lower fees or higher throughput, coupled with regulatory crackdowns on stablecoin issuance, might erode confidence in ETH collateral. This would prompt protocols to diversify into alternative assets such as wrapped BTC or tokenized property.
• Realistic base case: Ethereum remains the dominant collateral but sees incremental diversification. Protocols will add new asset classes (e.g., real‑world property tokens, green bonds) while maintaining ETH’s central role for liquidity and risk management. Layer‑2 solutions will mitigate fee pressure, keeping user experience favorable.

For retail investors, the key takeaway is that exposure to ETH collateral remains a core component of DeFi investing, but diversification into tokenized real‑world assets offers complementary risk profiles and yield opportunities.

6. Eden RWA: Tokenizing French Caribbean luxury real estate

Eden RWA exemplifies how real‑world asset tokenization can coexist with Ethereum collateral dynamics. The platform democratizes access to high‑end properties in Saint‑Barthélemy, Saint‑Martin, Guadeloupe, and Martinique by issuing ERC‑20 tokens that represent fractional ownership of a dedicated SPV (SCI/SAS).

Key features include:

• ERC‑20 property tokens: Each token (e.g., STB‑VILLA‑01) is backed 1:1 by the underlying villa held in an SPV, ensuring legal ownership transfer.
• Smart contract automation: Rental income streams are paid in USDC directly to investors’ Ethereum wallets. Smart contracts enforce distribution schedules and auditability.
• DAO‑light governance: Token holders can vote on major decisions such as renovation, sale timing, or villa usage, while day‑to‑day operations remain streamlined through the platform’s internal DAO structure.
• Experiential layer: Quarterly raffles award a token holder a free week in their partially owned villa, adding tangible value beyond passive income.
Secondary market potential: A compliant marketplace is planned to enhance liquidity for investors seeking to exit before the next valuation cycle.

Eden RWA’s architecture leverages Ethereum’s mature tooling while introducing real‑world asset fundamentals. For DeFi protocols, integrating such tokenized assets can diversify collateral portfolios and unlock new yield streams without diluting ETH’s centrality in risk management frameworks.

8. Mini FAQ

What is over‑collateralization?

It’s the practice of requiring users to lock more value in collateral than the amount they wish to mint or borrow, typically expressed as a percentage (e.g., 150%). This buffer protects lenders from price volatility.

How does Ethereum 2.0 staking affect DeFi collateral?

Staking ETH earns passive rewards (~4–6% APY) that can be used to offset borrowing costs or enhance yield strategies, making ETH an attractive collateral choice.

Can I use tokenized real‑world assets as collateral in mainstream DeFi protocols?

Currently, most blue‑chip protocols support only native crypto assets (ETH, BTC, stablecoins). However, some newer platforms are exploring RWA integration for diversified collateral portfolios.

What risks do smart contract exploits pose to collateralized positions?

Exploiters can drain vaults or manipulate pricing mechanisms, leading to forced liquidations or loss of user funds. Rigorous audits and bug bounties help mitigate this risk.

How does liquidity differ between ETH and tokenized real‑world assets?

ETH enjoys deep exchange and on‑chain liquidity; tokenized RWA typically have lower secondary market depth, which can affect withdrawal speed during market stress.

9. Conclusion
