Ethereum’s Pectra upgrade made EIP-7702 a practical part of wallet design. An externally owned account can delegate behavior to code, enabling experiences such as batched actions, gas abstraction, and smart-account features without forcing every user into a completely separate account model.
The capability is powerful because delegated code can act with the account’s authority. That also makes the integration boundary critical. Ethereum’s current guidance advises dApps to work through standardized wallet interfaces and wallet-managed implementations rather than asking users to sign arbitrary delegation authorizations.
Choose the user problem before the account feature
Start with a measurable friction: too many approval transactions, users without gas, account recovery, recurring actions, session permissions, or multi-step onboarding. Select the smallest wallet capability that solves it. Adding “smart account” to a roadmap without a user journey creates security work without a clear benefit.
Document the fallback for wallets or networks that do not support the selected interface. The product should degrade to a transparent transaction flow rather than silently failing.
Integrate through wallet-managed standards
Use interfaces such as ERC-5792 wallet calls where supported to request batches and capabilities. Let the wallet choose trusted delegation code and present authorization. Do not design a web page that asks a user to paste a private key or sign an opaque EIP-7702 authorization outside a trusted wallet flow.
Inspect chain ID, nonce, requested calls, spend effects, and the wallet response. Treat a rejected or unsupported capability as an expected state.
- Capability discovery and compatible-wallet matrix
- Human-readable batch and spend preview
- Chain-specific authorization and replay protection
- Revocation or delegation reset path
- Fallback transactions and support diagnostics
Threat-model the delegated account
Review the delegation implementation, upgrade authority, storage layout, initialization, module permissions, paymaster, bundler, recovery, and interaction with existing assets. A malicious or vulnerable delegate can affect the whole account. Wallets and hardware providers may restrict implementations for this reason.
Test phishing and downgrade scenarios. Users need to distinguish an ordinary dApp transaction, a batched wallet call, and a change to account behavior.
Ship the UX, documentation, and audit together
BlockPlanet can prototype the wallet or dApp journey, implement the approved interfaces, build the website and help content, and coordinate security review. The release checklist should include supported wallets and networks, screenshots of authorization, recovery and revocation instructions, and incident ownership.
Measure completion rate, rejected capabilities, support tickets, gas sponsorship cost, and failed batches. Better account technology matters only if users can understand and complete the task safely.

Frequently asked questions
Does EIP-7702 turn every Ethereum account into a permanent smart contract?
It allows an EOA to delegate behavior to deployed code through a new authorization mechanism. The exact duration and reset behavior depend on the authorization and wallet implementation.
Should a dApp ask users to sign EIP-7702 authorizations directly?
Ethereum’s guidance says dApps should integrate through standardized wallet interfaces rather than expect direct authorization signatures. Wallets should control trusted delegation implementations.
Is an audit required?
A qualified security review is strongly advisable for delegation code, wallet modules, paymasters, bundlers, permissions, recovery, and the dApp integration. Define the exact scope and deployed version.
