Wallets on Ethereum

What You Probably Got Wrong

EIP-7702 is live. Since Pectra (May 7, 2025), regular EOAs can delegate execution to smart-contract code without migrating wallets. This enables batching, gas sponsorship, and session-key-style UX. This is NOT "coming soon." It shipped.

Account abstraction status: ERC-4337 is growing but still early (Feb 2026). Major implementations: Kernel (ZeroDev), Biconomy, Alchemy Account Kit, Pimlico. EntryPoint v0.7: 0x0000000071727De22E5E9d8BAf0edAc6f37da032.

Most secure storage: Hardware wallets alone are single points of failure. An audited multisig smart contract (e.g. Safe) is more secure. Multisig does not require multiple people; one user can control multiple keys on separate devices. In a 2-of-4 setup, three signers are the user’s wallets on separate devices (e.g., hardware wallet, phone hot wallet, laptop wallet). The fourth signer is a trusted contact for recovery. An attacker must compromise multiple devices, not one.

EIP-7702: Smart EOAs (Live Since May 2025)

EOAs can authorize delegated code execution from smart-contract code. This is not automatically "one and done" - the delegation can stay active until it is replaced or explicitly cleared.
