Inflows and Outflows

    What is the volume of ETH and a stablecoin of your choice that's moved between the Optimism network and the Ethereum network across the bridge? How has that changed over time?

    Optimism Bridge


    Optimism is designed so that users can send arbitrary messages between smart contracts on Optimism and Ethereum. This makes it possible to transfer assets, including ERC20 tokens, between the two networks. The exact mechanism by which this communication occurs differs depending on the direction in which messages are being sent.

    Optimism uses this functionality in the Standard bridge to allow users to deposit assets (ERC20s and ETH) from Ethereum to Optimism and also allow withdrawals of the same from Optimism back to Ethereum. See the developer documentation and examples on details on the inner workings of the Standard bridge.

    Methodology


    1. Get the daily unique users' action on Optimism Native Bridge.

    2. Calculate the daily ETH volume.

      \

    • We will use the terms of deposit as a bridge from Ethereum to Optimism and withdraw as a bridge from Optimism to Ethereum.

    • All the data from this study comes from the Optimism Native Bridge only.

    Perspective (1): Unique Users

    The number of unique depositors hovered at 2k at the start of the period, peaking in early Sep 2021 at 20k then gradually decreasing over time. On the other hand, the number of unique users who withdraw varies between 50 and 100 per week over the course of the period.

    The graphs depict the number of unique users using the Optimism bridge. Surprisingly, 96.4 percent, or approximately 172k unique users, have deposited (Bridging from Ethereum to Optimism) at least once, while the remaining 3.5 percent have withdrawn (Bridging from Optimism to Ethereum) at least once.

    This pie chart displays the total amount of ETH that has been deposited and withdrawn.

    The deposit proportion is relatively high at 69 percent, while the withdrawal proportion is 31 percent.

    Conclusion


    • The number of unique depositors hovered at 2k at the start of the period, peaked in early September 2021 at 20k, and then progressively declined.
    • The number of unique users who withdraw, on the other hand, varies between 50 and 100 per week during the course of the term.
    • 96.4 percent, or around 172k unique users, have deposited at least once, while the remaining 3.5 percent have withdrawn at least once (Bridging from Optimism to Ethereum).
    • During the period, the total deposit and withdrawal ETH volume was around 311k and 139.9k ETH, respectively.
    • When compared to the deposit volume, the withdrawal volume is rather small.

    Perspective (2): ETH Volume

    The overall deposit and withdrawal ETH volume during has been roughly 311k and 139.9k ETH, respectively.

    The charts depict the daily ETH volume on Optimism Native Bridge in terms of deposit and withdrawal. The deposit ETH volume has multiple peaks during the time, with the biggest being more than 97k ETH on the first week of August 2022. In comparison to the deposit volume, the withdrawal volume is quite modest throughout the period.
