Intro

According to zkSync docs, zkSync is a trustless protocol for scalable low-cost payments on Ethereum, powered by zkRollup technology. It uses zero-knowledge proofs and on-chain data availability to keep users' funds as safe as though they never left the mainnet.

Method

I queried ethereum.core.ez_eth_transfers table and selected distinct wallets depositing ETH to zkSync address 0xabea9132b05a70803a4e85094fd0e1800777fbef in the last 60 days.

I summed the daily deposit amount in the last 60 days to get the daily volume of ETH deposited.

Result

We see an uptrend in the volume of distinct ETH depositors from April 26 with retracements on May 1 and May 2, this uptrend lasted till May 9 from where we see the volume declining steeply following the depegging of UST from the US dollar, reaching a low of 92 depositors on May 12.

It did not take long for depositors to gain back confidence in the market as we see another uptrend on the following days reaching a peak of 2804 depositors on May 17. There was a daily minimum of 1000 distinct depositors on subsequent days save for May 26, May 30, June 8 and June 13.

In the above chart, on May 10 there was an uptrend in the daily volume of ETH deposits following the depegging of UST. May 12 is a particularly interesting day because while this day has the lowest number of distinct depositors - 92 in this timeframe from the previous chart, it surprisingly has the third highest daily ETH deposits in the timeframe in question.

We see another uptrend in ETH deposit volume on May 29 following a slight pump in the price of ETH.

Conclusion

• The depegging of UST caused a downtrend in the volume of unique ETH depositors to zkSync, although this downtrend lasted only a few days and volume of unique ETH depositors went back to and sometimes even exceeded previous levels.
• While the depegging of UST caused in downtrend for unique ETH depositors in this timeframe, it did the opposite for volume of ETH deposited and we end up seeing a timeframe-high deposit volume of 2,290 ETH on May 10.
• The trend of distinct ETH depositors and volume of ETH deposited mirror each other more often than not.

From this chart we can see that the trends of daily distinct ETH depositors daily volume of deposited ETH generally mirror each other. This observation does not always hold, evident on April 19 where we see an uptrend in the volume of ETH deposited and a downtrend in the number of distinct depositors.
