EIP-7702: Set EOA account code

As I check on the Geth client, as far as I’m aware, this is not the case. The code is not accounted as .newContract, and therefore it cannot be deleted.

That’s the correct behavior. SETCODE does not create a new account. This is disambiguated by EIP-6780:

A contract is considered created at the beginning of a create transaction or when a CREATE series operation begins execution (CREATE, CREATE2, and other operations that deploy contracts in the future). If a balance exists at the contract’s new address it is still considered to be a contract creation.

You’re right, this is just very confusing. Likely a result of spec thrashing. This should only apply to code executing instructions. I will update the EIP so it is clear.

EIP-7702: Set EOA account code

If a code reading instruction accesses a cold account during the resolution of delegated code, add an additional EIP-2929 COLD_ACCOUNT_READ_COST cost of 2600 gas to the normal cost and add the account to accessed_addresses . Otherwise, assess a WARM_STORAGE_READ_COST cost of 100 . This seems to suggest that each CODESIZE and CODECOPY operation adds another 100 gas. That’s not great for copying strings. Are those the applicable "code reading instruction"s, since EXTCODESIZE and EXTCODECOPY do …

Thanks for pointing this out ^^
Since this EIP is older than the set EOA one, and it also says:

and other operations that deploy contracts in the future

IMHO, it is ambiguous

AuthorizationList SETCODE is not a CREATE series operation because it is not an opcode at all.
