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.

4-3-2025 🏃🏼‍♀️ 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.

EntryPoint v0.8 is live! ✨ A major upgrade that v0.8 offers is native support for EIP-7702 ✨ This will allow any EOA that uses EIP-7702 to also make use of the pre-existing and comprehensive ERC-4337 ecosystem of bundlers and paymasters.

I’d also argue that it is about having various providers independently verify the underlying data so we don’t have to trust any one service.

Curious what account abstraction really means? Wonder what the Ethereum Foundation actually does? Come to my talk on March 27 at Building Blocks Tel Aviv, Israel’s biggest crypto event, co-hosted by @collidervc, @starkwareltd, @fireblocks, @fhenix, and @ssv-network. Hope to see you there!
