A smart contract is a small program that lives on a blockchain and runs exactly as written, automatically, when its conditions are met. It is the building block behind most of decentralized finance, stablecoins, and on-chain applications.
Code as the intermediary
Instead of a bank or broker enforcing an agreement, a smart contract holds the funds and enforces the rules itself. If the conditions are met, it executes; if not, it does not. There is no manager to appeal to.
Power and peril
That automation enables genuinely new services, but it also concentrates risk in code: a bug or exploit can drain funds instantly, and “the code is the contract” means mistakes are often irreversible. Audits reduce risk but never eliminate it.
