❓ Frequently Asked Questions

No! Just go to lyra.works and start coding. Everything runs in your browser.

No! You can learn and practice without any crypto. The IDE has a "JavaScript VM" mode that simulates a blockchain locally. When you're ready to deploy for real, you'll need MetaMask and testnet ETH (which is free).

Yes, 100% free and open source. No hidden fees, no premium tier. MIT licensed.

Check the error message - it usually tells you what's wrong
Make sure your Solidity version matches your code
Check the FAQ page for common issues
Open an issue if you're stuck

Absolutely! That's one of the main use cases. You can share links to specific examples, and students can code along in their browsers. No setup required.

Install MetaMask
Get testnet ETH from a faucet (free)
Connect your wallet on Lyra
Select your network (e.g., Sepolia, Mumbai)
Click "Deploy" - your contract is now on the blockchain!

Please open an issue! We appreciate all feedback.
