Balancer pool doesn’t work with deflationary coins, creating a coin that relies on balancer was a mistake. Hacker exploited flash loans to arb all the sta away and take all the liquidity out

It’s not a flaw with sta either. It’s a flaw with how deflationary coins interact with balancer. Any deflationary coin could be exploited like this on balancer

Incorrect. It’s an issue Deflationary tokens and balancer. Which fucking sucks because I actually really supported STA in theory. I only held 20K of them and haven’t really lost much. But fucking hell thats the end of that project.

Why hasn’t Balancer announced something publicly? Where’s the transparency? STA has announced and says it’s an exploit in BAL pools.

It’s on their discord. It involves the deflationary aspect of the token not working well with balancer. Someone posted a screenshot in the other threads

These trips confirm. Do not put deflationary tokens into balancer. This is why I, YOUR TYRANT, did not add CID to a balancer pool.
>>19994349
It means that balancer does not currently work properly with deflationary tokens, and someone exploited the flaw to scrape out the eth from the system.

>> No.19994453

>>19994408
Not at all
>>19994349
Deflationary tokens don’t make sense with smart contracts since they send more tokens than they receive. This confounds some aspect of the balancer smart contract and so flash loans were used to exploit this interaction. There is an explanation screenshot somewhere

>>19994408
Look, the balancer expects to receive 100 tokens when 100 tokens are sent to it. If the token is deflationary, it receives less than the 100. This in turn fucks up it's proportions in the pool. If you kick it all the way down and then withdraw the last of that token, you essentially pull out the whole pool.

>> No.19994496

So basically, Balancer is flawed?

>> No.19994499

>>19994453
it's the other way around, they send less than they receive

>>19994499
Yeah whoops, sorry

>> No.19994518

>>19994496
No, deflationary tokens themselves are flawed interacting with smart contracts. Just happens that the guy targeted sta because of the big liq. It can happen to any deflationary token in balancer.

Is it finished? It says beta. They could probably fix this bug by changing the order of the processes in their code that determines the pool proportions.

>>19993647
They were warned multiple times that Balancer does not support deflationary tokens and there may be unknown effects. Now they are just trying to deflect blame. Balancer is decentralized like Uniswap so it's not like the developers can stop people from making a pool. All they can do is warn them like in this case. The blame falls firmly on the STA devs and they know it.

I thought balancer could centralize things easily after they created a centralized white list of tokens in their discord channel. am i wrong?
