Celo has journeyed from an independent Layer 1 to a fully integrated Ethereum Layer 2 and this is almost complete. This isn’t just an upgrade—it’s a return home, fully aligned with Ethereum’s L2-centric vision. After months of rigorous testing, community collaboration, and engineering breakthroughs, they’re ready to make it official:
Celo L2 Mainnet Activates on: March 26, 2025, at 3:00 AM UTC
At this moment, the Celo Layer 1 client will stop syncing, and the Layer 2 client will take over. If you run a full node and haven’t upgraded yet, do it now.
What This Means for You
Built on OP Stack and secured by Ethereum with EigenDA for data availability, Celo L2 is now a highly scalable, low-cost network that stays true to its mission of financial inclusion.
This transition isn’t just about technology—it’s about strengthening Celo’s place in the Ethereum ecosystem. Instead of forcing users and developers to migrate to a new chain, they’re making the move seamless through a hardfork. That means:
Minimal Disruption – Only full nodes need to upgrade; for most users and developers, it’s business as usual.
Faster Transactions – Block times are dropping from 5 seconds to 1 second, making transactions near-instant.
Network History Preserved – No regenesis needed. All past transactions remain accessible.
Less Tech Debt, More Innovation – They eliminated 365,000 lines of outdated code, making future upgrades easier and faster.
Seamless Ethereum Integration – CELO will now have a stronger presence in the broader Ethereum ecosystem, with deep composability and native bridging.
What’s Next?
With mainnet activation just weeks away, here’s what to expect:
Ecosystem Readiness – They’re working with dApps, tooling providers, and partners to ensure a smooth transition. Weekly community calls will help answer questions and prepare teams for launch.
Stage 1 Enhancements – Expect ongoing improvements to fraud-proof systems, exit mechanisms, and governance structures to maximize security and decentralization.
Conclusion
This milestone belongs to every engineer, validator, developer, and community member who contributed to Celo’s evolution. This is a new era—one that strengthens Celo within Ethereum’s ecosystem while staying true to its mission.
