Who proposed #ERC-4337 ?
It is an account abstraction proposal released by Ethereum founder Vitalik Buterin in conjunction with Yoav Weis, Dror Tirosh and others.
The proposal aims to make Ethereum wallets more user-friendly and prevent any key loss.
Vitalik and his team propose turning users’ externally owned accounts (EOA) into smart contract accounts (CA), which would allow built-in mechanisms for users to maintain access to their cryptocurrencies.
