Definition ∞ An agreement trigger refers to a predefined condition or event that initiates the execution of terms within a smart contract or a decentralized agreement. This mechanism ensures that contractual obligations are automatically carried out once specified criteria are met. It forms a fundamental component of automated, trustless transactions on blockchain platforms. The trigger eliminates the need for intermediaries in verifying conditions.
Context ∞ Understanding agreement triggers is vital for analyzing the functionality and security of decentralized applications and financial instruments. News about protocol upgrades or new dApp launches often details the specific triggers that govern their operations. Disputes or vulnerabilities can sometimes stem from unforeseen interactions or ambiguities within these trigger conditions.
