Smart Contract

Autonomous subsystems executing on blockchain infrastructure — code that runs when triggered, enforcing agreements without intermediaries.

Smart contracts are deterministic programs stored on-chain. Given the same state and inputs, they always produce the same outputs. They enable complex flows (token swaps, lending, governance) to execute trustlessly according to programmed logic.

Systems Connection

A smart contract is a component within the larger blockchain system. It has its own state (storage variables), interfaces (function signatures), and function (what it does when called). Composable smart contracts form subsystems — DeFi protocols built from interacting contracts.
