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.

Farcaster is all about decentralization right? But the default wallet experience is still based on EOAs. No smart contract logic, no session keys, no programmable recovery. Gasless swaps are great, but they’re just a backend patch. With 4337 I could sign with passkeys like Face ID. I could also get rid of a lot of pop-ups with session keys by pre authorizing specific actions. I could batch actions together like following someone and tipping them in 1 click. I could use onchain permissions I.e. covering gas for someone who has posted daily in a specific channel. Communities or creators could sponsor gas by role. Also please add account recovery :) my DMs are open if you want to chat.

Another one of those days where I’m reminded how lucky I am to be building on Ethereum We actually have a shot at shifting power from institutions to people It begins with money but it leads to a world where no single algorithm, studio,or institution decides what gets seen, funded, or remembered
