Some fucking dude just got destroyed by sending 232 eth to POWH shadow.

Fucking crypto is always so entertaining. Just tossed 10$ into normal POWH before everyone piles into it

If you guys want to know what happened....

Go to read smart contract, you will see that "reserve" = 115792089237316195418029001632089845036668699831288073378681090919681116870265

that is 0x10000000000000000000000000000000000000000000000000000000000000000
In hex

Basically a number (negative zero) got casted to positive huge number... signed -> unsigned int

>>	Anonymous Tue Jan 30 23:19:52 2018 No.7124753 >>7124720 >t. mindlet Dude more than 1 million eth are stuck because of the parity multisign fiasco, 900 eth aint shit

Original POWH:
var numEthers = getEtherForTokens(amount);

Shadow POWH:
var fees = (uint)(getEtherForTokens(amount)/10);
var numEthers = getEtherForTokens(amount) - fees;

Int overflow from that cast destroyed the contract and left $1M dollars in limbo forever.

This nigga literally changed 1 line of code and fucked the entire contract, way to fuckin go, there's literally no way he can fuck that worse. Even exit scamming would have been better, at least he would have been competent.

yes, check the contract right now. these values are clearly fucked: https://etherscan.io/address/0x9f4fd6c336388f2ab7dc7bbe4740ae7b88b880d7#readContract

And if you look at all the transactions, everything fails... bummer for you, but someone lost almost a quarter million dollars.

lmao muh ETH is the future.
one bug can fuck up a whole smart contract with this shitty technology. what a shitcoin

on a sidenote, why dont they just open a new fork and grant the public adresses that sent in the same amount of tokens they got in the shadowfork by premining them?

>>7125970
from the shadowfork page:
"To put it in Laymans terms, the eth is all stuck in the contract because the robot that was giving it out thinks its going to take infintie gas to divvy out negative dividends caused by a programming error on a single line of division."

I dont know solidity and my coding is a bit rusty but in the line

var fees = (uint)(getEtherForTokens(amount)/10);

he casts (getEtherForTokens(amount)/10) to int, uint is unsigned int, and can only store positive numbers including 0, some weird transfer fees resulted in a negative or very small number that when casted to unsigned int caused a overflow error, crashing and causing the contract to self destruct, hence all 800ETH +are lost forever
