The OpenZeppelin Contract Wizard is an interactive tool that helps you create secure, standard-compliant smart contracts for Sei EVM. Its interface generates production-ready contract code based on OpenZeppelin’s battle-tested libraries. Use the embedded wizard below to explore and create your custom smart contracts.

Benefits of using the wizard

  • All generated contracts use audited, industry-standard implementations from OpenZeppelin.
  • The wizard saves time because it removes boilerplate code and common setup configurations.
  • You can tailor contracts to your specific requirements through the UI.
  • You can learn best practices by examining professionally structured contract code.
  • The wizard always generates code that is compatible with the latest Solidity versions and standards.

Available contract types

Step-by-step guide

  1. Access the wizard: Use the embedded OpenZeppelin widget above, or go to wizard.openzeppelin.com.
  2. Select the contract type: Choose the standard that matches your project needs, such as ERC20 or ERC721.
  3. Configure basic settings:
    • Set the token name and symbol
    • Choose the Solidity version
    • Select the access control mechanism, such as Ownable or Roles
  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 the 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 to compile and deploy.

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 after generation: The wizard gives you a starting point. Most projects need more customization.

Try it: deploy from the browser

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