Smart Contract Architecture

Definition ∞ Smart contract architecture refers to the structural design and organization of self-executing digital agreements on a blockchain. This includes the code logic, data storage mechanisms, and interaction patterns between different contract components. A robust architecture ensures security, efficiency, and upgradeability of decentralized applications.
Context ∞ The integrity and functionality of decentralized finance (DeFi) protocols and other blockchain applications depend critically on their smart contract architecture. News frequently reports on security audits, vulnerabilities, or successful upgrades related to these foundational codebases. Discussions often center on best practices for designing secure and resilient smart contracts to prevent exploits.
