Ethereum's Layer 2 made splashes recently with names such as TikTok and Visa making announcements related to it. NFTs continued their relentless march to adoption as even Twitter teased a feature highlighting them. It wasn't all happy news though, as regulatory changes made in China forced Spark Pool and Gas Now to shut down their widely used services.

On Etherscan's side, we pushed a number of features this month: DEX Trading Pairs, IDM and Transaction Error Messages chief among them.

In this issue we take a look at how much has changed for bridges on Ethereum in the four months since we last analyzed them. For our poll, we quiz you on Ethereum's Layer 2. Answer it and stand a chance to win $10 in ETH!

Questions received last month:

Are error messages for transactions safe to follow?
Error messages are written by a contract's creators. Some may include links to phishing sites that prey on unsuspecting users. We advise caution when interacting with messages that suggest steps or link to external sites.

Why do some ERC-1155 tokens not have names or symbols?
The ERC-1155 token standard does not require the inclusion of Name and Symbol functions, leading some projects to neglect them. If you know a particular token's name, let us know! We will verify and update if it's correct.
