Celo L2 Testnets
As part of the transition to a L2, Celo has been operating two Layer 2 testnets: Dango, which was live form July till September 2024, and Alfajores, which was upgraded to Layer 2 on the 26th of September 2024.
With Alfajores L2 being live, transactions from Dango will not be synced to Alfajores L2. Testnets are for testing and experimentation. Tokens have no real-world value, and you may encounter bugs and limitations.
Alfajores L2 Upgrade
The Alfajores testnet was upgraded to a Layer 2 on the 26th of September 2024. This upgrade will transition Alfajores into the Celo Layer 2 environment, allowing developers and integrators to start building and testing with the new infrastructure. This is a key step in Celo’s broader evolution, paving the way for future upgrades to the Baklava testnet and the mainnet.
Key features of Alfajores L2 include:
- Full Alfajores history and state
- CELO token duality (ability to use CELO natively and as an ERC20 token)
- Fee abstraction (ability to pay for gas with tokens)
- Native Bridging to and from the L1
- Data Availability via EigenDA
- Staking
- Ultragreen Money
Dango Testnet - not live anymore
The Dango Testnet was announced on the 7th of July 2024, Celo’s first Layer 2 public test network. Dango allows developers and infrastructure providers to familiarize themselves with the Layer 2 environment. On the 26th of September 2024, when Alfajores L2 went live, it was shut down and the transactions from Dango weren't synced to Alfajores L2.
