I also heard that a lot has made free money out of the Arbitrum airdrop. I think I didn't qualify because I didn't use their platform. I'm also not updated with what's the latest in the altcoin community nowadays.

Thank you for sharing this zksync update. I have stumbled upon this many times but I got no idea what it is or what they are actually contributing to the crypto community. But I guess it is worth looking into. I haven't been following the new DApps in the market lately. This could be interesting to check.
