THE UNSEEN MARKET

Ethereum has a second market hiding underneath the block.

Standard block explorers stop at L1 transactions. BlobLens decodes what happens inside the parallel blob space.

Stop at transaction hashes and raw bytes. Cannot inspect packing efficiency, fee regimes, or sequencer timing.

✓ BLOBLENS OBSERVATORY

Decodes fees · blobs · rollups · packing · utilization · timing · congestion in real-time.
