DA Builder aggregates transactions to eliminate redundant execution layer costs, saving rollups and other entities substantial amounts on transaction costs while improving transaction inclusion speed and reliability.

​
The Cost Problem

While various fees receive significant attention, execution layer gas costs represent the bulk of expenses for most transactions. Current Reality: Each entity pays full execution costs for their individual transaction submissions, including the 21,000 gas minimum transaction overhead for every submission. For rollups and L2s, this cost can directly impact submission frequency, which can affect time-to-finality and withdrawal times. When submission costs are too high, rollups can reduce posting frequency and thus increase latency for users. High costs can similarly impact operational efficiency and user experience for other onchain applications that regularly submit transactions.

​
The Aggregation Solution

Transaction aggregation solves execution layer costs by sharing transaction overhead. When multiple entities submit transactions using the same L1 transaction:
  • Shared execution costs: The 21k minimum gas cost is paid once and split across all participants, reducing per-transaction overhead. Savings increase as more participants join.
  • Faster inclusion: Aggregated transactions become premium candidates for block inclusion, improving confirmation times for users.
  • Better positioning: Favorable positioning in blocks
  • Dual layer revert protection: Multi-layered protection against transaction reverts through internal checks and builder partnerships, reducing failed transaction risk.
  • MEV protection: Transactions are protected from toxic MEV and frontrunning, preserving execution value and user experience.
