New year new role 🚨 I’ve joined @ethereum as part of the Account & Chain Abstraction Team! This new chapter is deeply connected to a goal I’ve held: to positively impact 1 billion people in my lifetime. To me, Ethereum is the perfect place to make that happen.

4-13-2025 🧑‍🧑‍🧒‍🧒 Spent the day with family preparing for Seder part 2 tonight. I wasn’t originally going to come home for pesach but then I thought about Sahil Bloom’s graph that shows how our time with family diminishes as we age. As an adult, it’s easy to not take the flight home and choose convenience. I want to prioritize family time more and I’m glad I have the ability to do so 🙏🏻

At a Bitcoin conference today and I noticed that there’s a much higher % of anons than at ETH conferences. Maybe because Bitcoin price is still high 🫠

4-11-2025 🏧 Over the next couple years, we’ll see Account Abstraction evolve from smart contract wallets (ERC-4337) to native AA with EIP-7701. This will be good for: 1. End Users 2. Developers 3. Institutions 7701 will standardize things like: 1. Key management + rotation 2. Flexible transaction fees in any whitelisted token 3. Interoperability and privacy with zk proofs + standardized accounts

4-9-2025 🧾 It’s almost as if a dumb economic policy hurts the economy? Tariffs are on pause for now 👀 I really haven’t seen a single good take in favor of the tariffs.

4-8-2025 🗞️ Set up a new automation to track our work better and worked on some things related to Rollup Geth. Getting things into the L1 takes time so with Rollup Geth we can put things L2s agree on into a fork of Geth. This will standardize interop between L2s and make it easier for people to build on them.

4-7-2025 💵 I've been looking at the code behind major wallet implementations and it is crazy how people claim to do one thing and then do another behind the scene. Or just forget to update things etc. I think there needs to be more code accountability for wallets but more on that to come.

4-6-2025 📱 Got a good day of work done today. Still so behind on my telegram messages which are never ending. The amount of groups I’m in is untenable but working on a little hack to hopefully fix this.

4-5-2025 🐟 Went to Akko today and felt like a crusader! Akko is one of the oldest continuously inhabited cities in the world, at over 4,000 years old. It was a key Canaanite and Phoenician port, later conquered by the Greeks, Romans, and Crusaders, who made it their capital in the Holy Land. During the Crusader era, it was a fortified coastal city until it fell to the Mamluks in 1291. The Ottomans rebuilt Akko in the 18th century, and it became a vibrant trading hub under the rule of Ahmad al-Jazzar aka the butcher. Today, Akko is a UNESCO World Heritage Site known for its remarkably preserved Crusader and Ottoman architecture. Population wise it has both Jews and Arabs and is quite a mixed city.

4-4-2025 🌴 She’s back in Tel Aviv in the land of sunshine and palm trees. Caught up on work messages today - the amount of group chats we have is insane and I feel like if I miss even 2 days of work it is so hard to catch up.

4-3-2025 🏃🏼‍♀️ Went to the Panathenaic Stadium today - the site of the first Olympic Games in 1896. Was pretty cool to be in such a huge arena. Also I went to the Olympic museum which has the torches from all the Olympic Games.
