Pricing constraints

Each constraint targets a gas rate over a window. Exceeding one grows its backlog, and the backlog is what raises the base fee.

Gas target → blobs

Batches go to Ethereum as EIP-4844 blobs. A higher target means more throughput, more compressed bytes, and more blobs.

Blob base fee0.010 gwei

blobs/block = gas/s × B/gas × 12s ÷ 126,976

B/gas is measured over 40 blocks spanning ~32s: calldata brotli-compressed at level 1 (3.55×), plus 80B per tx for the incompressible signature.

It varies roughly ±25% with the traffic mix, so treat the output as an order of magnitude and drag the ratio to see the sensitivity.

Blob cost0.02 ETH/day

The chain's L1 base fee estimate is 0, so DA is not charged to users — raising the target moves this number, not what users pay.

Blobs are a fixed 128 KiB (126,976 usable bytes), so throughput adds blob count, not blob size.
