Definition ∞ Code fragility characterizes software that is highly vulnerable to breaking or malfunctioning with minor modifications or unexpected inputs. This trait indicates a lack of resilience in a program’s construction, making it susceptible to errors or security vulnerabilities. Such code frequently features tightly coupled components and inadequate error handling mechanisms.
Context ∞ Within smart contracts and blockchain protocols, code fragility represents a significant security exposure, frequently resulting in exploits and financial losses reported in cryptocurrency news. Developers consistently aim to reduce this risk by implementing thorough testing and formal verification methods. Robust code is fundamental to the reliability and trustworthiness of digital asset systems.
