Ethereum Blob Gas & Data Availability Estimator
EIP-4844 introduced dedicated blob space for Layer 2 rollups (Base, Arbitrum, Optimism, Scroll). This tool estimates the data availability cost differential between legacy calldata and temporary blob storage.
Blob Savings % = ((Calldata_Gas_Cost - Blob_Gas_Cost) / Calldata_Gas_Cost) * 100 How It Works
Compare transaction calldata gas cost vs. EIP-4844 blob space costs across L2 rollups.
