Our verdict on Blobsender
BlobSender may suit people who want to publish or share a message using Ethereum's EIP-4844 blobs. Its main appeal is a direct, stated use case: putting notes or other content into Ethereum blobs. The main caveat is that blobs are temporary data availability, not permanent storage. The project has not published its fees, audit status, or team details, and its homepage does not explain the submission flow. Check the app's terms and costs before posting.
