The OpenZeppelin Contract Wizard is a powerful interactive tool that simplifies the creation of secure, standard-compliant smart contracts for Sei EVM. It provides a user-friendly interface for generating production-ready contract code based on OpenZeppelin’s battle-tested libraries. Explore and create your custom smart contracts using the embedded wizard below.

​
Benefits of Using the Wizard

  • Security First: All generated contracts use audited, industry-standard implementations from OpenZeppelin
  • Time-Saving: Eliminate boilerplate code and common setup configurations
  • Customizable: Tailor contracts to your specific requirements through an intuitive UI
  • Educational: Learn best practices by examining professionally structured contract code
  • Up-to-Date: Always generates code compatible with the latest Solidity versions and standards

Step-by-Step Guide

  1. Access the Wizard: Use the embedded widget from OpenZeppelin above or visit wizard.openzeppelin.com
  2. Select Contract Type: Choose the standard that matches your project needs (ERC20, ERC721, etc.)
  3. Configure Basic Settings:
    • Set token name and symbol
    • Choose Solidity version
    • Select access control mechanism (Ownable, Roles, etc.)
  4. Add Security Features:
    • Pausable functionality
    • Permit extensions
    • Flash minting capabilities
    • Voting mechanisms
  5. Customize Token Behavior:
    • Premint options
    • Burning capabilities
    • Token transfer rules
    • Supply management
  6. Review Generated Code: The code updates in real-time as you make selections
  7. Copy and Implement: Use the “Copy to clipboard” button to export your contract code
  8. Deploy: The generated code is ready for compilation and deployment

​
Tips for Effective Use

  • Start Simple: Begin with minimal features and add complexity incrementally
  • Understand Each Option: Hover over the question icons (?) for detailed explanations
  • Review Dependencies: Note which OpenZeppelin libraries your contract imports
  • Consider Gas Costs: More features generally mean higher deployment and operation costs
  • Customize Post-Generation: The wizard provides a starting point—most projects will require additional customization

​
Try it: deploy from the browser

Once the wizard generates your contract, you can compile and deploy it to Sei testnet without any local setup. The Remix sandbox below is preloaded with a sample OpenZeppelin ERC-20 — replace it with your generated code, compile under Solidity Compiler, then Deploy & Run with Environment set to Injected Provider — MetaMask.
