# OpenZeppelin Contracts for Sui > Audited, composable Move building blocks for the Sui blockchain - start from > reviewed primitives instead of writing security-critical code from scratch. > Browse the catalogs below to discover what's available. A pointer file ([llmstxt.org](https://llmstxt.org/)) - nothing is restated here; follow the links to the sources of truth. ## Start here - [ARCHITECTURE.md](ARCHITECTURE.md): why the library is shaped this way and how to compose it - [contracts/](contracts/README.md) and [math/](math/README.md): the package catalogs - browse for the available packages, their MVR slugs, paths, and docs ## For each package - **README** - what it does, when to use it, install snippet - **`examples/`** - compilable integration examples (composition recipes) - **API reference** - generated from doc-comments (`sui move build --doc`), published at `https://docs.openzeppelin.com/contracts-sui/1.x/api/` - [audits/](audits/README.md) - audit reports and their scope ## Dependencies Pin stable releases from the Move Registry (MVR): `dep = { r.mvr = "@openzeppelin-move/" }` - see each package's README install snippet for the exact name.
