Liquidation Buffer Sizing

Liquidation buffer sizing refers to the mathematical calculation of the additional collateral margin required above the minimum maintenance margin to protect a decentralized exchange or derivatives protocol against sudden price volatility. In high-leverage environments, asset prices can move faster than an automated liquidation engine can execute trades.

By setting a buffer, the protocol ensures that even if an asset drops sharply, there is enough equity to cover the position closure costs without depleting the insurance fund. This mechanism acts as a critical safety valve in systems risk management.

It balances capital efficiency for traders with the solvency requirements of the smart contract. Proper sizing accounts for the specific liquidity depth of the underlying asset, the speed of oracle price updates, and the expected slippage during liquidation.

If the buffer is too small, the protocol risks insolvency; if too large, it traps capital and reduces trader leverage. This is a fundamental concept in managing systemic contagion risk within blockchain financial markets.
