FAQ

General Questions

1. What is Q-Remix IDE? Q-Remix IDE is a smart contract development platform built for ease and power. It leverages the Monaco Editor (the same as VS Code), providing tools for writing, compiling, deploying, and interacting with smart contracts. It’s designed to be beginner-friendly while offering advanced features like AI-assisted coding, real-time feedback, and robust deployment environments.

Editor and Compilation

2. What editor does Q-Remix use? Q-Remix uses the Monaco Editor, which supports syntax highlighting for Solidity, JavaScript, and more—offering a smooth, intelligent coding experience.

3. How do I compile a smart contract in Q-Remix? To compile a contract:

  • Click the Compiler Icon 🛠️ in the left sidebar.

  • Select the appropriate Solidity version.

  • Choose the .sol file to compile.

  • Click Compile.

4. What happens after a successful compilation? Upon successful compilation, Q-Remix generates:

  • ABI (Application Binary Interface)

  • Bytecode

These are stored in the artifacts/ folder for deployment and interaction.

5. What should I do if there are errors during compilation? Errors will appear in the compiler panel, highlighting the file, line number, and description of the issue to help you debug efficiently.

Deployment and Interaction

6. How do I deploy a contract in Q-Remix? To deploy:

  • Click the Deploy & Run tab.

  • Choose an environment: Q-Remix VM or Injected Provider (MetaMask).

  • Select the account.

  • Choose the compiled contract.

  • Click Deploy.

Deployment details appear in the terminal, including the contract address and transaction hash.

7. What environments are supported for deployment?

  • Q-Remix VM: A local environment powered by Hardhat, with 20 test accounts (10,000 ETH each). State persists unless the tab is closed.

  • Injected Provider - MetaMask: Connects to Ethereum Mainnet or Testnets like Goerli or Sepolia via MetaMask.

8. How do I interact with a deployed contract? Go to the Deployed Contracts section:

  • Click a contract to expand its functions.

  • Input required parameters and click the function’s button to call it.

  • Outputs like transaction hash, gas used, and returned values appear in the terminal.

Settings and Customization

9. How can I change the theme or language of the IDE?

  • Open the Settings panel.

  • Use the toggles to switch between light/dark themes.

  • Select your preferred language.

  • Click Reset to Default Settings to revert to the original setup.

10. What does the "Reset to Default Settings" button do? It resets:

  • Theme to Light Mode

  • Language to English Useful for restoring default preferences.

Troubleshooting

11. Why are my contract states resetting when using Q-Remix VM? Contract states are preserved only as long as the browser tab remains open. Closing the tab resets the state and test accounts.

12. Can I deploy a contract on Ethereum Mainnet using MetaMask in Q-Remix? Yes. Use the Injected Provider - MetaMask option to deploy to Ethereum Mainnet or supported testnets like Goerli or Sepolia.

13. How many deployed contracts can I interact with in Q-Remix? Q-Remix retains the five most recently deployed contracts. Deploying additional contracts will push out the oldest one.
