Last updated 7 months ago

Overview

Loopring is a decentralized exchange and payment protocol that operates on Ethereum and its own Layer 2 solution, Loopring L2. Loopring L2 is a ZK rollup that posts batches of transactions to Ethereum with zk-SNARK proofs. The Loopring Dune query can be found .

Query Structure

The query filters successful transactions sent to the LoopringIOExchangeOwner that call the submitBlocksWithCallbacks function.

Calculations

  • The proof volume is the sum of successful submitBlocksWithCallbacks function calls

  • The cost is calculated using the following formula:

    • cost=∑traces(gas_used×gas_price×eth_price) \text{cost} = \sum_{\text{traces}} \left( \text{gas\_used} \times \text{gas\_price} \times \text{eth\_price} \right) cost=∑traces​(gas_used×gas_price×eth_price)

    • Where:

      • gas_used\text{gas\_used}gas_used is the amount of gas consumed by a trace in one of the verifiers

      • gas_price\text{gas\_price}gas_price is the price of gas on the day of the transaction

      • eth_price\text{eth\_price}eth_price is the average price of ETH in USD on the day of the transaction
