Definition ∞ A post-launch vulnerability refers to a security flaw or weakness discovered in a digital asset protocol, smart contract, or application after it has been deployed and is actively operating. These vulnerabilities were not identified during initial audits or testing phases and can expose the system to exploits, leading to asset loss or operational disruption. Their discovery often necessitates urgent patches, upgrades, or even temporary halts in service. Such flaws present significant risks to live blockchain systems.
Context ∞ Post-launch vulnerabilities are a recurring subject in cryptocurrency news, often associated with emergency upgrades, security incidents, and project responses. The rapid evolution of blockchain technology means that new attack vectors can emerge even after thorough initial reviews. Continuous monitoring, bug bounty programs, and a responsive development team are crucial for addressing these issues promptly. The industry prioritizes swift and transparent communication when such vulnerabilities are identified.
