Ethereum Co-Founder Vitalik Buterin Discusses Account Abstraction Progress


At the Ethereum Community Conference (EthCC) in Paris on July 18, Vitalik Buterin, co-founder of, provided an in-depth review of the ongoing development and challenges of blockchain’s account abstraction. He discussed the concept, which is aimed at increasing Ethereum’s adaptability by allowing users to choose their own account security models.

Buterin started by recalling the birth of account abstraction on Ethereum. “Right from the start, we were all about letting accounts be controlled by code, not just keys,” he said. However, some obstacles, such as non-unique transaction hashes and the sorting of miner fees from smart contract wallets, had to be overcome.

Subsequently, the EIP-4337 account abstraction standard was released. It works by sticking to smart contracts and does not require changing the base protocol. This allows wallets to communicate through a trusted “entry point”. Additionally, “bundlers” are used to group meta-transactions, while MEV markets are handled by MEV manufacturers.

Buterin went on to explain the importance of signature aggregation. This process combines signatures together and can reduce data and gas costs. He also discussed the need for an Ethereum Improvement Proposal, which would enable externally-owned accounts to be converted into smart contracts. Finally, he touched upon the challenges of ensuring layer-2 solutions are compatible with existing technologies such as biometrics, wallets, and layer-2 solutions.

Despite the challenges, Buterin is optimistic about Ethereum’s account abstraction journey. “We’ve come a long way with account abstraction, and I can’t wait to see where we’ll go next,” he concluded.
