(1/16) It's Friday! You know that means I have a 🧵 for you on this week's #Ethereum #Layer2 happenings! #L222 is truly flourishing. Enjoy! 👇

(2/16) The bridge 🌉 design space is heating up! Bridges are necessary but also a potentially lucrative attack vector. Take a look at @bkiepuszewski's excellent 🧵on risk frameworks for considering #Layer2 bridges:

(3/16) @mycomeg and @schmiddominik1 put together a really informative document on what the growth of #Layer2 protocols means for the broader Ethereum ecosystem. I'm quoted in it so I'm a bit biased but it is a fantastic read! 🙂 consensys.net/blog/blockchai…

(4/16) RSS3 @rss3_ protocol and nodes now fully support @arbitrum for content and data indexing! This will allow for a lot more data visualization about what is happening on #Arbitrum, a pretty big deal! 🔢

(5/16) I've always thought alt-L1s would become L2s, and the "data availability" narrative is a great nexus. @CelestiaOrg announced their "Quantum Gravity Bridge" this week, a project they are developing which seeks to provide an off-chain DA mechanism.

(6/16) @Immutable announced instant purchases of #Layer2 $USDC using a credit card. Swiftly moving the needle on L2 user experience. Amazing!

(9/16) @08351ty released a thread on the @starknet ecosystem, with a discussion on some cool projects making headway. One cool thing to watch will be projects which innovate in ways that the EVM and gas costs made impossible. That's where the alpha is IMO.

(10/16) There's a new dashboard for tracking how much #rollups are paying to secure the #Ethereum network, in L1 fees paid by L2s. Check it out here: l2fees.info/l1-fees

(11/16) @saurik discovered and reported a critical bug in @optimismPBC this week. The bug would have allowed the attacker to print an arbitrary quantity of tokens! Wowsa, glad that the white hats won this one. Read more about what happened here: saurik.com/optimism.html

(12/16) For @optimismPBC's post mortem on the critical bug, see here:

(13/16) Want to know more about #NFTs on the @optimismPBC #Layer2? @moon_guurl put together a helpful video for getting started!

(14/16) #Arbitrum's @sgoldfed & @SizeChad joined @DeezeFi to talk about NFTs on Layer 2. The short version: #NFTs on #Layer2 will lower barriers to entry, bridging solutions are forthcoming, and the Layer 2 NFT community is beginning to flourish!
