OpenZeppelin Contracts is a library for secure smart contract development.
What it does
OpenZeppelin Contracts is a library of pre-built, battle-tested building blocks that developers use to create smart contracts — self-executing agreements that run on blockchain networks like Ethereum. Think of it as a set of trusted, reusable Lego pieces that handle common functionality like digital token creation and access controls, so teams don't have to build everything from scratch.
Why it matters for PMs
With nearly 27,000 stars and over 12,000 forks, this is one of the most widely adopted foundations in the blockchain development ecosystem, meaning a huge portion of crypto products and Web3 startups are built on top of it. For founders and investors, a product team using OpenZeppelin signals they're following industry security best practices rather than rolling their own untested code — which significantly reduces the risk of costly hacks or vulnerabilities.
