web3.bridge-blob-space Calculator
Calculates EIP-4844 blob space consumption, blob fee cost, and data availability overhead for cross-chain asset bridging and interoperability on rollup chains. EIP-4844 introduced blob transactions to Ethereum with a separate fee market — blobs target 3 blobs/block (384 KB) and are pruned after ~18 days, reducing rollup DA costs by 10–100×.
