Ok. There is one project, which operates on POA Ethereum Private Chain. There was no info about it in withdrawal section, and I used my own ETH address (where I have full controll on it). I sent a lot of money that way.
I know for sure it is POA Eth Priv Chain. One person from the team said to me, that they don't need my private key to bring back my tokens. Is this possible on POA chain?

I heard it is possible to send back my coins, how?

Can they do that?

it works quite identical to public ethereum in terms of creating transactions. if you don't hold your own privkey, you cannot create transactions.
I cannot make any comments regarding their claims.

TY, I pmed you TX from their blockchain explorer. If you can, take a look. If not, thank you anyway.

Did I understand correctly that you sent assets inside that blockchain somewhere and you're asking whether they can be returned to you?

Hmm, how can you deploy opcodes directly?

(and why would anyone ever want to)

I don't see any opcodes there. That's assembly

Yes, assembly is closer to opcodes directly

Yeah not my speciality either. My point was mostly that assembly is not *required* for create2

That's why I asked before. Is there any advantage in using assembly rather than using solidity code

Dec 23, 2020, 7:12 AM

It is recommended to avoid assembly but in many cases you may have to perform some operations which can't be done using solidity

Dec 23, 2020, 7:14 AM

Can you give an example for such a case?

Dec 23, 2020, 7:16 AM

To check whether an address is a smart contract or EOA

Dec 23, 2020, 7:16 AM

Oohh yeah that isContract() function

Thanks✌
