What is EIP-7702?

It's an Ethereum Improvement Proposal introduced as part of the Pectra upgrade, which went live on May 7, 2025.

It boosts the functionality Externally Owned Accounts (EOAs) by allowing them to temporarily adopt smart contract functionality, without actually needing to migrate to a new address or deploy a separate smart contract.

One of the main use-cases of this improved functionality is transaction batching. With EIP-7702, multiple actions can be batched into one transaction, which was previously only possible through smart contracts.
