OpenZeppelin Contracts Wizard for Solidity

Interactively build a contract out of components from OpenZeppelin Contracts. Provide parameters and desired features for the kind of contract that you want, 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.

This package provides a programmatic API. For a web interface, see https://wizard.openzeppelin.com

Installation

npm install @openzeppelin/wizard

Contract types

The following contract types are supported:

• erc20
• erc721
• erc1155
• stablecoin
• realWorldAsset
• account
• governor
• custom

Note that stablecoin, realWorldAsset, and account are experimental and may be subject to change.

Each contract type has functions/constants as defined below.

Functions

print

function print(opts?: ERC20Options): string

function print(opts?: ERC721Options): string

function print(opts?: ERC1155Options): string

function print(opts?: StablecoinOptions): string

function print(opts?: AccountOptions): string

function print(opts?: GovernorOptions): string

function print(opts?: CustomOptions): string

Returns a string representation of a contract generated using the provided options. If opts is not provided, uses defaults.

defaults

const defaults: Required<ERC20Options>

const defaults: Required<ERC721Options>

const defaults: Required<ERC1155Options>

const defaults: Required<StablecoinOptions>

const defaults: Required<AccountOptions>

const defaults: Required<GovernorOptions>

const defaults: Required<CustomOptions>

The default options that are used for print.

isAccessControlRequired

function isAccessControlRequired(opts: Partial<ERC20Options>): boolean

function isAccessControlRequired(opts: Partial<ERC721Options>): boolean

function isAccessControlRequired(opts: Partial<ERC1155Options>): boolean

function isAccessControlRequired(opts: Partial<StablecoinOptions>): boolean

function isAccessControlRequired(opts: Partial<GovernorOptions>): boolean

function isAccessControlRequired(opts: Partial<CustomOptions>): boolean

Whether any of the provided options require access control to be enabled. If this returns true, then calling print with the same options would cause the access option to default to 'ownable' if it was undefined or false.

Note that contracts such as account, have its own way of handling permissions and do not support the access option. Thus, that type does not include isAccessControlRequired.

Examples

Import the contract type(s) that you want to use from the @openzeppelin/wizard package:

import { erc20 } from '@openzeppelin/wizard';

To generate the source code for an ERC20 contract with all of the default settings:

const contract = erc20.print();

To generate the source code for an ERC20 contract with a custom name and symbol, along with some custom settings:

const contract = erc20.print({
  name: 'ExampleToken',
  symbol: 'ETK',
  burnable: true,
  premint: '1000000',
});

To generate the source code for an ERC20 contract with all of the defaults but is upgradeable using the UUPS proxy pattern:

const contract = erc20.print({
  ...erc20.defaults,
  upgradeable: 'uups',
});
