Shared blobs, save fees.
DA Builder automatically combines multiple blob transactions from multiple L2s into full blobs before submission, saving DA fees $$
Save fees & protect against gas spikes with shared blobs
DA Builder automatically combines multiple blob transactions from multiple L2s into full blobs before submission, saving DA fees $$
Why DA Builder?
Lower Costs
Share blob space across L2s to reduce Ethereum data submission fees & execution fees
Safe Participation
Economic and technical safeguards protect against spam and misuse.
Limited Downsides
If aggregation doesn’t improve the situation, the data is submitted as originally intended.
Efficient Aggregation
Economic and technical safeguards protect against spam and misuse.
Flexible Timelines
L2s can specify how long they’re willing to wait to be included in an aggregated blob.
L2 Rollups
Looking to reduce their data availability costs on Ethereum
Rollup-as-a-Service Providers
Optimizing infrastructure for multiple small clients
Appchains or Custom L2s
With bursty or inconsistent data needs
How it works?
L2 signs its own data blob and sends it to DA Builder
DA Builder aggregates & group them efficiently
Optimized blob is posted to Ethereum
