New year new role ๐Ÿšจ Iโ€™ve joined @ethereum as part of the Account & Chain Abstraction Team! This new chapter is deeply connected to a goal Iโ€™ve held: to positively impact 1 billion people in my lifetime. To me, Ethereum is the perfect place to make that happen.

EntryPoint v0.8 is live! โœจ A major upgrade that v0.8 offers is native support for EIP-7702 โœจ 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.

Iโ€™d also argue that it is about having various providers independently verify the underlying data so we donโ€™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, Israelโ€™s biggest crypto event, co-hosted by @collidervc, @starkwareltd, @fireblocks, @fhenix, and @ssv-network. Hope to see you there!
