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.

By coincidence (aka we are the same person), my boyfriend and I got each other the same gift for Valentine’s Day - a custom Lego build of us from the same random website. The instagram ads are working 😂

2-20-2025 🧾 There’s a lot of misconceptions around EIP-4337 vs. EIP-7702. What EIP-7702 doesn’t solve on its own: 1. No Gas Abstraction: Users still need ETH to pay for gas, unless combined with ERC-4337 paymasters. 2. No Persistent Smart Account: Once the transaction ends, the EOA reverts to its standard form without smart contract functionality. 3. No Decentralized Execution: Without 4337, users often rely on centralized relayers for transaction submission, as 7702 itself doesn’t include a decentralized bundler system. EIP-4337 and EIP-7702 work hand in hand to enable smart account functionality while maintaining censorship resistance and avoiding reliance on centralized relayers.

2-18-2025 🎤 Went on a podcast and hosted a Twitter space today. Did a lot of talking about builders who ship vs. people who just talk. Shippers stay shipping 🚢
