cairo-account
Make a custom smart contract that represents an account that can be deployed and interacted with other contracts, and can be extended to implement custom logic. An account is a special type of contract that is used to validate and execute transactions. Returns the source code of the generated contract, formatted in a Markdown code block. Does not write to disk.
cairo-custom
Make a custom smart contract. Returns the source code of the generated contract, formatted in a Markdown code block. Does not write to disk.
cairo-multisig
Make a multi-signature smart contract, requiring a quorum of registered signers to approve and collectively execute transactions. Returns the source code of the generated contract, formatted in a Markdown code block. Does not write to disk.
cairo-governor
Make a contract to implement governance, such as for a DAO. Returns the source code of the generated contract, formatted in a Markdown code block. Does not write to disk.
cairo-vesting
Make a vesting smart contract that manages the gradual release of ERC-20 tokens to a designated beneficiary based on a predefined vesting schedule. Returns the source code of the generated contract, formatted in a Markdown code block. Does not write to disk.
stellar-fungible
Make a fungible token per the Fungible Token Standard, compatible with SEP-41, similar to ERC-20. Returns the source code of the generated contract, formatted in a Markdown code block. Does not write to disk.
stellar-stablecoin
Make a stablecoin that uses Fungible Token Standard, compatible with SEP-41. Returns the source code of the generated contract, formatted in a Markdown code block. Does not write to disk.
stellar-non-fungible
Make a non-fungible token per the Non-Fungible Token Standard, compatible with SEP-50, similar to ERC-721. Returns the source code of the generated contract, formatted in a Markdown code block. Does not write to disk.
stylus-erc20
Make a fungible token per the ERC-20 standard. Returns the source code of the generated contract, formatted in a Markdown code block. Does not write to disk.
stylus-erc721
Make a non-fungible token per the ERC-721 standard. Returns the source code of the generated contract, formatted in a Markdown code block. Does not write to disk.
stylus-erc1155
Make a non-fungible token per the ERC-1155 standard. Returns the source code of the generated contract, formatted in a Markdown code block. Does not write to disk.
README
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
MCP Servers
MCP Servers allow AI agents to generate smart contracts with the same options as the Contracts Wizard.
For local installation, see the Contracts MCP Server package.
For a hosted version, see OpenZeppelin MCP Servers.
TypeScript API
You can use the programmatic TypeScript API to generate contracts from your own applications.
View the API documentation for each smart contract language:
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>.
