Isolated Collateral Risk Parameters vs Cross-Pool Risk Parameters

Specific advantage: Risk is siloed per market. A depeg of a volatile asset like stETH or a hack on a new LST does not cascade to other pools.

This matters for protocols launching novel assets (e.g., Aave's GHO launch pool) or integrating highly volatile collateral where the primary goal is to protect the core protocol treasury and existing users.

Specific advantage: Each pool can have unique Loan-to-Value (LTV) ratios, liquidation thresholds, and oracle configurations. For example, a pool for real-world assets (RWAs) can use a specialized oracle and conservative 50% LTV, while a blue-chip ETH pool can be more aggressive.

This matters for institutional deployments and protocols requiring bespoke risk rules for different asset classes without compromising the entire system.

Specific advantage: All collateral in the protocol backs all debt. A user can borrow against a diversified portfolio (e.g., 60% ETH, 30% WBTC, 10% stablecoins) as a single, more robust position.

This matters for sophisticated users and DAO treasuries seeking to maximize leverage and utility of their entire asset portfolio, as seen in MakerDAO's Single Vault (Vault 2.0) model.

Specific advantage: One unified liquidity pool for borrowing. There's no need to manually allocate funds to specific isolated markets. Debt is fungible across all collateral types.

This matters for retail-focused applications and money markets like Compound v2, where the priority is ease of use and deep, aggregated liquidity for popular assets like USDC and WETH.

Specific advantage: Risk is siloed to individual asset pools. A depeg or exploit in one pool (e.g., a specific LST) does not threaten the solvency of others. This matters for protocols listing experimental or volatile assets (e.g., RWA, new LSTs) without jeopardizing core stablecoin liquidity.

Specific advantage: Liquidity providers can target specific risk/reward profiles. An LP can supply high-yield, high-risk collateral without being forced to share its yield with safer pools. This matters for specialized funds or DAOs seeking to maximize returns on specific asset convictions.

Specific advantage: A unified collateral base absorbs volatility shocks. If one asset dips, others backstop the system, preventing immediate liquidations. This matters for maximizing stability and borrowing power for flagship stablecoins like DAI, where a diverse, shared backstop is critical.

Specific advantage: Borrowers can draw debt against the aggregate value of all approved collateral, not just a single pool. This unlocks higher loan-to-value ratios and more flexible positions. This matters for large, diversified holders (e.g., DAO treasuries, whales) who want to leverage a portfolio as a single position.

Specific disadvantage: Requires per-asset risk parameter governance (LTV, liquidation threshold). This leads to fragmented governance overhead and slower iteration. Aave governance must vote on parameters for each new isolated market, which can be a bottleneck for rapid asset onboarding.

Specific disadvantage: A severe failure in a major collateral asset can threaten the entire system's solvency, requiring emergency shutdowns or global parameter changes. This matters for risk-averse institutions who prioritize worst-case scenario insulation over marginal capital efficiency gains.

Specific advantage: Risk is siloed. A default in one pool (e.g., a volatile altcoin) cannot drain collateral from unrelated pools (e.g., ETH, stablecoins). This matters for protocol security and risk assessment, as seen in platforms like Solend and Radiant Capital on specific chains.

Specific advantage: Each pool's Loan-to-Value (LTV), liquidation thresholds, and oracle dependencies are set independently. This matters for protocols launching new, exotic assets, allowing aggressive parameters for blue-chips (80% LTV) and conservative ones for long-tail assets (40% LTV) without cross-contamination.

Specific advantage: Collateral in one pool can back borrowing across the entire protocol, unlocking deeper liquidity. This matters for maximizing user leverage and yield, as pioneered by MakerDAO's DAI and Aave's unified pools, leading to higher Total Value Locked (TVL) and better rates.

Specific weakness: A correlated market crash or oracle failure on a major asset (like ETH) can trigger cascading liquidations across all pools, threatening protocol solvency. This matters for risk managers evaluating black swan scenarios, as seen in stress tests for Compound and Euler (pre-hack).

New protocols launching risky assets, specialized lending markets (NFTfi, RWA), or multi-chain deployments where local risk profiles vary. Examples: Marginfi on Solana, Radiant on Arbitrum (for specific assets).

Established blue-chip protocols prioritizing liquidity depth and user convenience, stablecoin issuers like MakerDAO needing robust collateral backing, or generalized money markets like Aave v3 where asset correlation is well-understood.
