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.
