Parameter Range Constraints

Parameter range constraints involve enforcing limits on input values to ensure they remain within safe, logical boundaries. For example, a slippage parameter should not be allowed to exceed a reasonable percentage, and a withdrawal amount must not exceed the user's balance.

By validating these constraints, protocols prevent logic errors and protect against extreme market conditions. These checks are typically performed using require statements or custom modifiers.

This is essential for maintaining the stability of derivative instruments and liquidity pools. It prevents users from accidentally or intentionally causing system failures.

Proper range checking is a key aspect of defensive programming in the DeFi domain.
