Smart Contract Logic

Definition ∞ Smart contract logic refers to the predefined, self-executing code embedded within a smart contract that dictates its behavior and conditions for execution. This code specifies the rules, terms, and actions that will automatically occur when certain criteria are met. It ensures deterministic and tamper-proof execution of agreements on a blockchain. It forms the operational core of decentralized applications.
Context ∞ The integrity and security of smart contract logic are paramount concerns in the decentralized finance and blockchain development communities. Discussions often focus on auditing, formal verification, and vulnerability detection to prevent exploits. Future advancements in programming languages and development tools aim to enhance the robustness and reliability of smart contract logic, reducing risks for users.
