Documentation Overview
OpenZeppelin Contracts Wizard
Contracts Wizard is a web application to interactively build a contract out of components from OpenZeppelin Contracts. Select the kind of contract that you want, set your parameters and desired features, and the Wizard will generate all of the code necessary. The resulting code is ready to be compiled and deployed, or it can serve as a starting point and customized further with application specific logic.
Usage
Use the Contracts Wizard at https://wizard.openzeppelin.com
CLI
Generate contracts from the command line. See the CLI package.
MCP Servers
Allow AI agents to generate contracts. See the MCP package for local installation, or OpenZeppelin MCP Servers for a hosted version.
TypeScript API
Generate contracts programmatically from your own applications.

Embedding
To embed Contracts Wizard on your site, first include the script tag:
<script async src="https://wizard.openzeppelin.com/build/embed.js"></script>
Then place <oz-wizard></oz-wizard> in the body where you want Contracts Wizard to load.
Optionally focus on specific tab with the data-tab attribute as in <oz-wizard data-tab="ERC721"></oz-wizard>.
For languages other than Solidity, use the data-lang attribute, for example: <oz-wizard data-lang="cairo"></oz-wizard>.
