address(uint160(manager.pancakeswapDepositAddress())).transfer(address(this).balance)

If I am not wrong, this is what the code does:

Creates a variable address, collects the address from Manager, calls a transfer method that moves the balance of address of the current contract "interactor"

All of that at once? In this single statement?

no address here is a type, not a variable. it's a cast. And yes transfer is something very native of ether virtual machine so single statement

you found an exemple for arbitrage or flashloan I don't know... but it's a bad example, you won't have anything to learn out of it but some keywords....

Nov 8, 2021, 6:32 PM

Oh, yeah. I get that. I didn't phrase it well. Create an "address type" variable. Thanks.

Thanks for the help so far. I appreciate.

a deployed contract has an "object like" type, and can bu "under casted" to address

Nov 8, 2021, 6:33 PM

I think there's one more thing I'd like to show you.

Damn! Neat.

payable(manager.pancakeswapDepositAddress()).transfer(300000000000000000)

How about this, Maxime?

Nov 8, 2021, 6:35 PM

and the cast to uint160 is a "work around" to do this kind of undercast. I don't know why solidity forbid the cast of a contract to an address

it gives some money to the manager, this time the cast is to payable but it's pretty much the same

Nov 8, 2021, 6:36 PM

So the hacker casted to uint160, before recasting to "address" to undercast the "Manager" contract?

Nov 8, 2021, 6:37 PM

yes

direct cast to address makes the contract won't compile, I don't know why

Nov 8, 2021, 6:37 PM

Okay, thanks. But, if all your money is gone in the previous piece, what's with the new one? Some kind of disguise? Wouldn't work?

Nov 8, 2021, 6:38 PM

and your second line transfer 0.3 bnb from the contract to the manager... if you deploy with "value" parameter > 0.3BNB, you will lose your money

Nov 8, 2021, 6:38 PM

Understood.

Nov 8, 2021, 6:38 PM

I don't know

I think it's a kid who tried to scam but didn"t manage it :D

Nov 8, 2021, 6:38 PM

This "30000000..." is 0.3 BNB?😳

Nov 8, 2021, 6:39 PM

yes https://bscscan.com/unitconverter

Nov 8, 2021, 6:39 PM

To the manager? Or what?

Nov 8, 2021, 6:40 PM

yes

Nov 8, 2021, 6:40 PM

Thanksssss a lottt!

Last question.

How did you know this was a BSC contract?

Nov 8, 2021, 6:40 PM

I saw pancake :D

Nov 8, 2021, 6:41 PM

Smart. If it was ETH, what could possibly be there?🤔

Nov 8, 2021, 6:41 PM

uniswap V2.

I saw the kind of projects and methods you are trying to call, this example is for pancake arbitrage

Nov 8, 2021, 6:41 PM

Learnt a lot.💃💃💃

Nov 8, 2021, 6:42 PM

but if you want to learn how to flashloan and do arbitrage, you should try to read uniswap contracts or 1inch, but not shitty example

Nov 8, 2021, 6:42 PM

A link or two would help. Thanks.👍👍
