We’re excited to announce that DA Builder, our blob aggregation protocol, is now live on Ethereum mainnet!
Significant cost savings for rollups and users are finally here.
🧵👇
DA Builder aggregates blob submission from multiple L2s into a single transaction to Ethereum — reducing DA costs significantly without compromising trust assumptions.
DA Builder also enables:
- Protection against gas price spikes for L2s
- Faster finality (for faster bridging, withdrawals, and improved security)
It’s built to integrate with any rollup and slot naturally into your existing workflow!
DA Builder is a key part of the based rollup future we are building for Ethereum, as based rollups post blobs much more frequently than other rollups.
Our work on designing a full stack and robust based ecosystem directly inspired this new product.
Join this X Space next Friday at 10am ET on blob aggregation innovation and based rollups — featuring @gusgonzalezs (Taiko), @linoscope (Nethermind), @tonydenyer (Spire), and moderated by @mteamisloading!
