Blob.Tools is the ultimate frictionless UI/UX application designed to streamline blob migration paths to Celestia and facilitate initial backup syncs with their original Data Availability solution. Leveraging EIP-4844, Blob.Tools targets ZKSync Era's Blobs, offering a seamless, user-friendly experience.

Simply enter the batch number into the URL query, and you're set. For example, accessing batch #470000 is as easy as navigating to https://blob.tools/?b=470000. Our robust backend system automatically extracts the blob from ZKSync ERA's EIP-4844, submits it to Celestia, and calculates the price differences—effortlessly providing you with the data you need.
