Let's take a look at the total and daily number of unique wallets that deposited or withdrawn ETH to/from Optimism via its native bridge over past 60 days.

Here's the total numbers for deposits.

Over 72.9k unique addresses made 86.9k deposit transactions in the past 60 days.

And here's the daily number of deposits.

We see some little increases on late Apr, but from May the number of addresses and transactions they made went down and stayed below 500 daily addresses and transactions, until last days of May which the numbers increased a little.

On last day of May and especially Jun 1 we see a huge spike in the number of wallets and deposit transactions. On June 1st 23.52k unique addresses made over 26.2k deposit transactions via the native bridge. The numbers gradually went down during next days and went below 500 again on Jun 13th.

Now let's see the same data, but this time for withdraw transactions.

Only 772 unique addresses withdrawn ETH from Optimism native bridge in past 60 days. This 772 wallets made 1.5k transactions though.

On deposits chart the number of unique wallets and transactions was close, but in withdraw chart we see that the number of unique addresses and transactions they made are much different that what we saw in deposits chart. That is clearly visible in the above chart by looking at the space that bars (showing unique wallets) and the line (showing number of transactions) have from each other. There are some weird numbers though. For example, on May 28th we have 216 withdraw transactions that have been executed by only 13 different wallets, or on Apr 22nd we have 7 wallets that made 188 withdraw transactions.

Following the general trend we see that for most days the number of unique wallets that withdrawn ETH using Optimism native bridge was between 10 to 15, but coming to last week or so, we have more number of wallets that made more withdraw transactions.

And in overall the numbers we see for withdrawals are much lower compared to deposits. We can say the numbers on withdrawal chart are almost 1-tenth of deposits.
