• Testnet and Contract Addresses

In contrast to OP Mainnet sequencer which writes TX batches to Ethereum in the form of calldata or, more recently, EIP-4844 blobs to commit to the transactions included in the canonical L2 chain, Celo uses EigenDA as an alternative data availability layer in order to minimize the TX fees. EigenDA is a data availability store made by EigenLabs and built on top of EigenLayer. With EigenDA, TX data is stored by EigenDA operators off-chain, only DA commitments used for verficiation and subsequent data retrieval are stored On Ethereum which significantly reduces DA costs and L2 TX fees.

The integration is done in accordance with the Optimism's Alt-DA spec which contains a more in-depth description of this interface.

Testnet and Contract Addresses

The Celo Dango testnet uses the EigenDA Holesky testnet. For the current list of deployed contract addresses, please refer to the EigenLayer's Current Testnet Deployment page.
