OP Avail Testnet

Overview

OP Avail testnet is an OP stack powered L2 that uses Avail as its data availability layer.
In OP Avail, L2 transaction data are written to Avail instead of Ethereum calldata. The resulting unique transaction reference blob key is then written to Ethereum calldata. By doing so, the cost of publishing on Ethereum becomes relatively negligible, even when the actual data is megabytes in size. The rollup node will then be able to retrieve the data commitments from the calldata on Ethereum, and then retrieve the transaction data from Avail.
To learn more about OP Avail, refer to the guide Build a Rollup With Avail.
