Smart Contract
A smart contract is a computer program deployed on a blockchain that executes deterministically and automatically when its conditions are met, without a trusted third party.

Smart contracts are the foundational brick of DeFi, NFTs, DAOs and, more broadly, every decentralised application (dApp). They are written in dedicated languages - Solidity for Ethereum and its Layer 2s, Rust for Solana and NEAR, Move for Aptos and Sui.
Once deployed, a smart contract is generally immutable: a bug can be catastrophic. That is why specialised security audits and bug bounties are a mandatory step before mainnet deployment.
