* **Data Availability Types**:
* **Calldata** is generally simpler but can be more expensive on mainnet Ethereum, depending on gas prices.
* **Blobs** are typically lower cost when your chain has enough transaction volume to fill large chunks of data.
* The `op-batcher` can toggle between these approaches by setting the `--data-availability-type=<blobs|calldata>` flag or with the `OP_BATCHER_DATA_AVAILABILITY_TYPE` env variable.
* The `op-batcher` can toggle between these approaches by setting the `--data-availability-type=<blobs|calldata|auto>` flag or with the `OP_BATCHER_DATA_AVAILABILITY_TYPE` env variable. Setting this flag to `auto` will allow the batcher to automatically switch between `calldata` and `blobs` based on the current L1 gas price.
