| Free tier | No free tier. Live cost at time of check: $0.012 per MB as blobs (vs $11.01/MB as calldata). 128 KB per blob package, separate blob fee market. unit MB; metered on unstated |
|---|---|
| Price | none stated |
| Limits |
~18-day retention; per-block blob count cap; cost floats with the blob fee market. |
| Identity | card (inferred, not read) not published |
| Egress | Free to read while data exists, but data is pruned by consensus nodes after ~18 days. Retrieval after that depends on third-party archival indexers (Blobscan etc.), not on Ethereum. |
| Per-object cap | 128 KB per blob (128000 bytes) |
| Retention | ~18-day retention; per-block blob count cap; cost floats with the blob fee market. (18 days) |
| Interface | rest rest |
| Tooling | blobkit.org (TypeScript SDK for blob transactions), Blobscan API, standard Ethereum JSON-RPC. |
| Composes with | Multiply cost, not capacity: 10 TiB/month = 10,485,760 MB x $0.012 = ~$125,800/month, and the data expires in 18 days regardless of payment. |
| Reliability | Data is intentionally ephemeral by protocol design — the network is built to forget it after the DA window. |
