Q1. Many blockchain bridges exist allowing users to move assets between different blockchains. One of the blockchains currently receiving a lot of bridge volume is Optimism. There are several bridges you can use to move tokens to Optimism, but for this bounty we are particularly interested in Optimism’s bridge. You can find more information on their native bridge here and here.

How many distinct wallets have deposited or withdrawn ETH to Optimism via the native bridge in the last 60 days? Visualize your findings.

The volume of ETH deposited into Optimism has risen since May 23 and peaked on May 30. The volume of ETH withdrawed reached its highest level on June 8 and has increased since then.

As can be seen from the chart above, the number of deposit actions has been much higher than the withdrawal actions in the last 60 days.

The number of wallets that have deposited ETH in the last 60 days has been much more than the number of wallets that have been withdrawed ETH. The reason could be related to Optimism AirDrop token. The number of wallets deposited by ETH also peaked on May 30 and June 1.

• The cumulative ETH deposited into Optimism in the last 60 days : 68.8 K.
• The cumulative ETH withdrawed from Optimism in the last 60 days : 27.1 K.

98% of wallets in the last 60 days have deposited ETH into the Optimism Layer 2 network.
