Developer Onboarding
Start your journey toward developing decentralized applications on the Celo platform.
As of block height 31,056,500 (March 26, 2025, 3:00 AM UTC), Celo is no longer a standalone Layer 1 blockchain—it is now an Ethereum Layer 2! Some documentation may be outdated as updates are in progress. If you encounter issues, please file a bug report.
For the most up-to-date information, refer to our Celo L2 documentation.
