Ethereum

As of May 2022, Yoav Weiss has been working as a Security Fellow at the Ethereum Foundation while also working as a self-employed Security Consultant since January 1996. One of his main roles has been developing the account abstraction technology for ERC 4337, which enables the deployment of smart contract wallets on Ethereum with arbitrary verification logic. ^[8]

“So now, users don’t need to think about writing down 12 words on a piece of paper, but instead, they are able to add and remove devices and include recovery options with a friend or a lawyer,” Weiss said.

He has made several appearances at conferences, representing Ethereum, explaining the intricacies of the new technology and the advantages that come with ERC 4337. One of his main goals as of now is to make on-chain adoption as simple as possible whilst maintaining security, especially for newcomers. ^[3][5][6]

"I am focused on improving usability and security for the next billion users, making it easier for the rest of the world to join us. I don’t think the next billion users are going to use private keys and write walls of text on a piece of paper; we need to abstract it away. That has been my focus: Making it easy to develop wallets so that users don’t even need to know that there is a private key involved."

On March 1, 2023, during WalletCon in Denver, Yoav Weiss, a security researcher from the Ethereum Foundation, announced that the primary contracts for ERC-4337, commonly referred to as "account abstraction" by blockchain developers, had undergone an audit by Open Zeppelin and were approved for use on Ethereum mainnet and all Ethereum Virtual Machine (EVM) compatible networks, including Polygon, Optimism, Arbitrum, BNB Smart Chain, Avalanche, and Gnosis Chain. ^[7]
