The next Ethereum hard fork will include EIP-3074, allowing Externally Owned Accounts (EOAs) to delegate control to smart contracts and function like wallets. This works alongside ERC-4337 for transaction sponsoring/relaying.

As Ethereum grows into a multi-chain ecosystem, EIP-3074's inclusion ensures EOAs can work consistently across chains without needing extensive infrastructure like ERC-4337 requires.

After years of requests, EIP-3074 is finally making it into the next hard fork. Its low-risk implementation paves the way for future wallet advancements and the highly-anticipated migration of EOAs to smart contract accounts.

With EIP-3074 in the upcoming fork, developers gain new tools like AUTH and AUTHCALL for innovative wallet designs. It also solves the longstanding issue of migrating millions of EOAs to smart contract wallets.
