EIP-7702 is one of the most important developments in the smart wallet conversation because it changes what externally owned accounts can do. Instead of forcing users to migrate entirely into a smart contract wallet, EIP-7702 allows an EOA to set code through a new authorization mechanism.

This matters because most users already have EOAs. Their assets, approvals, identities, and histories may already sit inside existing wallet addresses. Asking everyone to move into new smart contract accounts creates friction. EIP-7702 points toward a future where existing accounts can access smart wallet-like features more directly.

The official EIP describes a new transaction type where authorization tuples allow code delegation. In practical terms, an EOA can delegate execution to code at another address. This can unlock features such as batching, gas sponsorship, delegated actions, and more flexible account behavior.

For users, the promise is smoother upgrades. A wallet could add smart account features without forcing a full account migration. Users might keep the same address while gaining better transaction flows, passkey support, sponsored gas, or limited permissions.

For developers, EIP-7702 expands the design space. Applications may be able to offer smart wallet UX to users who arrive with existing EOAs. This could reduce the gap between traditional wallet users and smart account users.

For infrastructure providers, EIP-7702 may blur the line between EOAs and smart wallets. Embedded wallets, browser wallets, account abstraction SDKs, and chain abstraction tools may compete in new ways.

The security implications are serious. If users can delegate account behavior, wallet interfaces must explain delegation clearly. A bad authorization can be more dangerous than a single bad transfer if it gives broad execution control.

EIP-7702 does not make ERC-4337 irrelevant. The two approaches may coexist. ERC-4337 provides a smart account transaction flow, while EIP-7702 gives EOAs a path toward programmability.

The future smart wallet may not look like a separate wallet category. It may become a capability layer that existing accounts activate when needed. That is why EIP-7702 matters: it brings smart wallet logic closer to the accounts people already use.
