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.

This is the flow I had to do to buy Farcaster Pro: 1. First, I had to swap USDC to ETH on Ethereum mainnet. 2. Then I had to bridge USDC on Ethereum mainnet to USDC on Base via the swap button. 3. Only then could I pay for Farcaster Pro. With an ERC-4337 paymaster this entire flow could have been 1 click. I would just sign one transaction: “Pay for Farcaster Pro in USDC.” Behind the scenes, the token paymaster handles gas in ERC20 tokens and I don’t need ETH. It can accept USDC on Ethereum, bridge it, and fund the gas on Base for me. I should be able to buy a subscription with the tokens I already have without swapping, bridging, or managing gas.

POV: you’re on a plane to Berlin and your laptop fan is louder than the engine because you forgot you agreed to speak like 4 times

6-4-2025 🏡 Home for 3 days until I head off to Berlin. It’s been a lot of travel and I am only in the middle of my current travel run which lasts until end of July. Craving a bit of peace and quiet. Hopefully August will be more restorative.

6-3-2025 🇵🇹 Thank you Algarve for the memories 🫶🏼 I didn’t get to disconnect as much as I would have liked but things come up that we can’t control. I’m heading home to lock in and prep for a big 10 days in Berlin. Let’s go 🚀

Knicks really looked greatness in the face and said “nah that’s not for us” firing Thibodeau makes no sense.

I wish Farcaster search was faster / more precise. @v @dwr.eth @ted are you guys working on improving the search feature at all?
