Why Set-and-Forget Collateral Parameters Are a Myth

Static parameters guarantee failure. They assume market volatility, asset correlation, and liquidity depth are constants. In reality, a stablecoin depeg or a protocol exploit like the Euler hack creates cascading liquidations that static models cannot predict.

The market is a feedback loop. Aave's risk parameters for a token like CRV are based on historical data, but a governance attack or a concentrated sell-off from a whale wallet like Curve's Michael Egorov changes the asset's fundamental risk profile instantly.

Evidence: The 2022 collapse of Terra's UST demonstrated this. Its algorithmic stability mechanism relied on a static arbitrage model, which failed when on-chain liquidity evaporated and off-chain sentiment turned, triggering a death spiral.

Static parameters guarantee failure. A loan-to-value (LTV) ratio set in 2021 for ETH fails when staking yields or volatility profiles shift. The optimal collateral factor is a function of market depth, asset correlation, and liquidation efficiency, all of which are non-static variables.

Protocols are not islands. A MakerDAO vault's health depends on oracle resilience and liquidator bot economics. If Chainlink updates its aggregation model or gas spikes render keepers unprofitable, your 'safe' 150% collateralization becomes a systemic risk overnight.

Evidence from Compound and Aave. Both protocols have executed over a dozen governance proposals to adjust risk parameters for assets like UNI and LINK. This isn't maintenance; it's a continuous parameter arms race against market structure evolution.

Static parameters are a vulnerability. A set-and-forget collateral factor ignores market volatility, creating systemic risk. MakerDAO's 2019 Black Thursday event, where a 30% ETH drop triggered cascading liquidations, proved this.

Adaptive systems use real-time oracles. Protocols like Aave V3 and Compound adjust Loan-to-Value (LTV) ratios and liquidation thresholds based on asset volatility feeds from Chainlink and Pyth Network.

Governance is the control loop. MakerDAO's Stability Fee and Aave's Reserve Factor are not static; they are dials adjusted by MKR and AAVE token holders in response to treasury data and market conditions.

Evidence: Aave V3's Ethereum pool has adjusted the wstETH collateral factor three times in 12 months, a direct response to Lido's staking derivative liquidity and volatility profile.

Static parameters guarantee failure. They assume a static world, but crypto markets are volatile. A collateral factor set for ETH at $2k fails catastrophically at $1k, triggering mass liquidations. MakerDAO’s 2018 stability fee adjustments prove reactive parameter updates are a core protocol function.

Set-and-forget is a governance cop-out. It delegates critical risk management to the initial team, creating a single point of failure. The alternative is not centralized control, but on-chain governance with explicit upgrade paths like Compound’s Governor Bravo or Aave’s decentralized risk stewards.

The evidence is in the exploits. Every major DeFi hack—from Iron Bank’s bad debt to Venus’s LUNA collapse—involved inflexible risk models. Protocols that survived, like Maker after Black Thursday, did so by abandoning dogma and dynamically adjusting vault parameters in response to market stress.
