Founded in 2021, Bundlr bundles multiple layer 2 transactions into a single Arweave (layer 1) transaction. The end user's data is protected in a permanent, decentralized space. For the developer, the data from the developer’s project will be stored on Arweave via Bundlr. As of today, over 90–98% of data uploads onto Arweave are conducted through Bundlr. Bundlr is also integrated with Aptos, Algorand, Boba, Fantom, and Near.
