Definition ∞ A code supply chain refers to the sequence of components, libraries, and tools used to develop, build, and deploy software, including blockchain applications. This chain encompasses all external dependencies, open-source packages, and proprietary modules that contribute to the final operational code. Each link in this chain presents a potential point of weakness if compromised, allowing malicious code to be injected into a project. Ensuring the integrity of this supply chain is paramount for the security of smart contracts and decentralized systems.
Context ∞ Security concerns surrounding the code supply chain are growing in prominence within the blockchain sector, particularly with the increasing reliance on third-party libraries and development tools. Recent security incidents have underscored the dangers of compromised dependencies, leading to calls for enhanced vetting and auditing processes. Efforts are underway to establish best practices for supply chain security, aiming to protect digital assets from subtle code injections.
