-EIP-7702 sets the account code of an Externally Owned Account (EOA) temporarily during a transaction. This enables EOAs to behave like smart contracts for the duration of a transaction without permanently modifying their code.
+EIP-7702 sets the account code of an Externally Owned Account (EOA) through a delegation transaction, enabling EOAs to behave like smart contracts.
 
 The `signDelegation` cheatcode generates a signed authorization for an implementation contract to be delegated to, ensuring that only authorized implementations can execute transactions on behalf of the authority account. The signature includes the authority account's nonce to prevent replay attacks.
