Smart Contract

Definition ∞ A Smart Contract is a self-executing contract with the terms of the agreement directly written into code. These contracts run on a blockchain, automatically executing actions when predefined conditions are met. They facilitate, verify, and enforce the negotiation or performance of a contract without the need for intermediaries.
Context ∞ Smart Contracts are foundational to decentralized applications (dApps) and decentralized finance (DeFi), with current discussions focusing on their security, upgradeability, and the development of more sophisticated functionalities. Analysts are examining the impact of new smart contract languages, audit methodologies, and the increasing complexity of on-chain logic on the security and utility of the blockchain ecosystem.
