Smart contracts are written in code — commonly Solidity on Ethereum and Ethereum-compatible chains — and deployed onto a blockchain, where they execute exactly as programmed whenever triggered, without needing a court, escrow agent, or company to enforce the terms. This is what powers most of DeFi, NFT marketplaces, and DAOs: the rules of the arrangement are public, verifiable, and self-executing.

The nuance that trips up newcomers is the industry phrase “code is law” — a smart contract does exactly what its code says, not necessarily what the parties intended if the code contains a bug or an unanticipated edge case. Because blockchain transactions are generally irreversible, a flaw in a smart contract’s logic can lead to permanent loss of funds with no customer-service department to appeal to, which is why serious projects pay for independent security audits before launch.

🇵🇭 Philippine Example

There is no dedicated Philippine law yet that specifically addresses the legal enforceability of smart contracts; existing contract law and e-commerce legislation (the Electronic Commerce Act) are generally the closest applicable framework, and how a Philippine court would treat a dispute arising purely from smart contract code has not been extensively tested. Founders building anything smart-contract-based for Filipino users should get Philippine-specific legal advice rather than assuming an overseas legal opinion transfers directly.
