Traditional Ethereum wallets usually make you sign transactions with an externally owned account (EOA); using an ERC-20 token can mean approving a spender in one transaction and using that approval in another. Account abstraction makes authorization, execution and fee payment programmable, which can enable batched actions or sponsored gas—but those capabilities depend on the wallet and its integrations. ERC-4337 smart-account flows and EIP-7702 EOA delegation are different mechanisms, and they can be used together.
What “traditional wallet approval” means
An EOA is controlled by a private key. In a typical token-payment flow, the wallet signs an on-chain transaction to grant an application permission to spend a token, then signs another transaction that uses that permission. The account generally needs ETH available to pay transaction gas.
That token permission is distinct from the wallet asking you to approve or sign a transaction: the first grants a spender an allowance, while the second authorizes an operation from your account. Some applications or wallet flows may differ, so check what the prompt is actually authorizing.
How account abstraction changes the flow
Account abstraction lets account code define more of the rules for validating and carrying out an action. Rather than treating every operation as a straightforward transaction signed and paid for by an EOA, a wallet can package actions, apply programmable permissions and arrange fee payment through supported infrastructure. These are possible capabilities, not guarantees that every wallet or application offers them.
ERC-4337 smart accounts
ERC-4337 represents an intended action as a UserOperation. A bundler submits it to the EntryPoint, which coordinates validation and execution. A paymaster may cover gas or support another payment arrangement, subject to its policy and the operation’s validation. ERC-4337 uses this alternative flow without requiring a change to Ethereum’s consensus rules.

EIP-7702 delegation for EOAs
EIP-7702 lets an EOA authorize a delegation to code while retaining its account address. Depending on wallet implementation, delegated code can enable features such as batching, sponsorship or narrower permissions. The wallet determines how these capabilities are requested and managed; an EOA address alone does not tell you what delegated behavior a particular prompt will authorize.
They are complementary, not competing wallet labels
ERC-4337 describes a smart-account transaction flow; EIP-7702 provides a way for EOAs to delegate execution to code. They operate at different layers and can be combined. A wallet’s product description is not enough to establish which mechanism a particular payment uses—inspect the operation and authorization details it presents.

Compare the payment choices
| Question | Traditional EOA flow | ERC-4337 smart-account flow | EIP-7702 delegated EOA |
|---|---|---|---|
| What authorizes execution? | The EOA’s private key signs the transaction. | A wallet encodes an intended action as a UserOperation, which is validated and executed through the EntryPoint. | The EOA authorizes a delegation to code; wallet implementation determines how users manage the delegated capability. |
| Can related actions be combined? | A token approval and a later use of that approval commonly require separate transactions. | Batching may combine related calls, depending on the wallet and application. | Delegated code can support batching, depending on wallet implementation. |
| Who pays gas? | The EOA generally needs ETH available for transaction gas. | A paymaster may cover gas or enable another payment arrangement, subject to policy and validation. | Sponsorship may be available through wallet implementation; availability and conditions are not universal. |
| What infrastructure is involved? | The ordinary EOA transaction flow; the supplied sources do not specify a universal service dependency. | A bundler and EntryPoint; a paymaster may also be involved. | Delegation support depends on the wallet and the delegated code; a particular flow’s service dependencies must be checked with its wallet. |
| What is not established as a universal value? | Comparative cost, completion time and user-error rate: not stated in the sources. | Comparative cost, completion time and user-error rate: not stated in the sources. | Comparative cost, completion time and user-error rate: not stated in the sources. |
Fees, supported tokens, sponsor policies and network compatibility vary by implementation. No controlled, apples-to-apples benchmark establishes that one approach is always cheaper, faster or less error-prone.
What to check before you confirm
- Action count and atomicity: Will the wallet combine the related calls into one operation, or will it still ask for separate approval and payment transactions?
- Fee payer and fallback: Is gas paid in ETH, covered by a sponsor, or handled another way? Find out what happens if the sponsor declines or is unavailable. Sponsorship is not a guarantee that the transaction is cost-free in every sense.
- Permission scope: Identify the contract or authority receiving permission and check whether access is limited by token, amount, application or time. Determine whether the prompt authorizes a one-time action, a limited session key or a broader delegation.
- Service dependence: Ask whether a relayer or other trusted service is required, and what happens if it goes offline. Ethereum.org’s guidance recommends avoiding designs that can brick an account when one trusted relayer is unavailable.
- Recovery and changes: Check how the account can be recovered, who can change its logic, and how modules or delegation contracts are reviewed.
- Compatibility: Confirm that the wallet and network support the requested behavior. Ethereum.org points to ERC-5792 for standardized batched-call interfaces and ERC-6900 for modular account capabilities.
Why EIP-7702 delegation needs particular care
A delegation is consequential because the authorized contract code can control assets in the EOA. Ethereum.org warns hardware wallets to be cautious when implementing EIP-7702 and recommends trusted delegation-contract lists rather than arbitrary delegation. A familiar address, a sponsored-gas prompt or a hardware wallet does not by itself make a delegation safe.
A hardware wallet can help protect key custody, but it does not remove smart-contract or delegation risk. Before authorizing, verify what code or authority the prompt names, what permissions it receives, how long those permissions last, and what revocation or recovery path the wallet provides.

Where the standards stand
Ethereum.org reports that the ERC-4337 EntryPoint was deployed on Ethereum Mainnet on March 1, 2023. Its page, last updated October 1, 2026, reports more than 26 million smart wallets and 170 million UserOperations. These are figures reported by Ethereum.org, not an independently audited count of unique users.

Separately, the Ethereum Foundation’s February 18, 2026 priorities update describes EIP-7702 as an important step toward a future in which smart-contract wallets are the default without bundlers, relayers or extra gas overhead. That is a roadmap direction, not a description of an already-deployed end state.
