Gas Consumption Analysis

Gas efficiency is a key design consideration, as it directly impacts user costs and the overall user experience. We have conducted a rigorous gas consumption analysis for all primary protocol operations to validate our commitment to on-chain performance.

The measurements were performed using the sui client replay-transaction tool, which provides a precise breakdown of computation and storage fees. You can learn more about this tool in the official Sui Replay CLI Documentation.

The following report details the gas costs for key user actions, providing transparency into the protocol's on-chain performance. These measurements reflect the engineering and optimization efforts invested to deliver a cost-effective trading experience.

Gas Fee Formulas

The following formulas calculate the storage fees from both the validator's and the user's perspectives:

  • Validator Perspective:

    $$ \text{storage_fee (validator)} = \text{old_rebates_sum} - \text{new_rebates_sum} - \text{non_refundable_storage_fee} $$

  • User Perspective: $$

    • \text{storage_fee (user)} = \text{new_rebates_sum} - \text{old_rebates_sum} + \text{non_refundable_storage_fee} $$
