EIP-7702 lets an EOA set code via a signed authorization, but you still need a storage layout that survives implementation swaps. Base's
eip-7702-proxy is a minimal ERC-1967 proxy that delegates a plain EOA to CoinbaseSmartWallet, keeping the account's address and history intact.Why it matters: the naive approach points the EOA directly at wallet logic, freezing you on one implementation and exposing you to initialization races. Routing through a 1967 proxy gives a stable upgrade slot and a controlled first-init path — the same discipline you already apply to contract upgrades, now for EOAs.
The subtle risk: an unguarded first delegation is front-runnable, so init authorization must be bound to the account. Read the proxy as a reference for that binding.
