OP EigenDA Testnet

Overview

OP EigenDA testnet is an OP stack powered L2 that uses EigenDA as its data availability layer.

In OP EigenDA, L2 transaction data are written to EigenDA instead of Ethereum calldata. The resulting EigenDA blob key is then written to Ethereum calldata. By doing so, the cost of the calldata becomes relatively negligible, even when the actual blob data is megabytes in size. The sequencer will then be able to retrieve the blob keys from the calldata and then retrieve the blob from EigenDA.
