Discuss Blockchain CBDE Exam Topic 5 Question 125

Using selfdestruct(beneficiary) with the beneficiary being a contract without a payable fallback function:

Awill throw an exception, because the fallback function is non-payable and thus cannot receive ether.

Bit's impossible to secure a contract against receiving ether, because selfdestruct will always send ether to the address in the argument. This is a design decision of the Ethereum platform.

Cselfdestruct doesn't send anything to a contract, it just re-assigns the owner of the contract to a new person. Sending ether must be done outside of selfdestruct.

Suggested Answer: B

A is clear. Can't send ether to a contract without a payable function.

Tambra 2 months ago

B is the best choice. It's a fundamental design of Ethereum.

Audry 2 months ago

I disagree with C. Selfdestruct definitely sends ether to the address.

Adrianna 2 months ago

A makes sense. If the fallback is non-payable, it should throw.

Jeniffer 2 months ago

I lean towards B. Selfdestruct always sends ether, can't avoid that.

I think A is correct. Non-payable means no ether can be received.

Wait, are we sure about B? That seems too absolute.

I’m confused about the implications of selfdestruct. Does it really just re-assign ownership? I thought it had to do with ether transfer too.

Lashawn 6 months ago

I feel like I saw a similar question where selfdestruct was discussed, and it mentioned that it doesn't actually send ether to a contract. So maybe C is the right choice?

Leslie 7 months ago

I'm not entirely sure, but I remember something about selfdestruct always sending ether. Could it be that option B is correct?

Jamika 7 months ago

I think option A makes sense because if the fallback function is non-payable, it can't accept ether, right?
