Railgun

Last updated 7 months ago

Overview

Railgun is a privacy-focused smart contract system that allows users to shield their cryptocurrency transactions on Ethereum. It uses ZK proofs to enable private transactions, where the transaction details (such as amounts and addresses) are hidden from public view while maintaining security and integrity. The Railgun Dune query can be found .

Query Structure

The query filters transactions sent to the RailgunSmartWallet that were successful and invoke the transact function.

Calculations

  • The proof volume is the sum of transact function calls

  • The cost is calculated using the following formula:

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

    • Where:

      • gas_used\text{gas\_used}gas_used is the amount of gas consumed by the transaction

        • gas_used\text{gas\_used}gas_used is temporarily hardcoded to an amount from example transactions

      • 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
