Help ! How to sell my ERC20 token or read the contract ?

[splouffy]

Hello,
I mistakenly invested in this token:

0x6f4Bf22f9058C008DedaC380E5F71bC07357dD2D

And now, I would like to leave this contract.



How to sell my altcoin or read the contract ?

When I click on the button: "exchange" it gives me no error message. But don't send anything. How to solve this problem ?

Since it's a new contract, maybe it's a temporary delay? How long? How to know ?

I put the slippage at 30% or 40% nothing helps; Uniswap is not responding.

On 1inch https://i.ibb.co/18kbdcj/Capture.jpg i see a locker...  And after the message :

Rate expired

The previous exchange rate has expired

Try one of the following options:

Try to swap at an updated rate
Increase slippage tolerance in the settings and swap again
Enable compatibility mode

I did all that but nothing changed! Even refreshing the transaction!

Most likely its the reason why you are not able to sell your coins:

edit: Check out the contract on etherscan. If it's not decompiled, decompile it.

in this case, the contract has a clause preventing anyone but the owner from swapping.

modifier ensure(address _from, address _to) {

address UNI = pairFor(0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f, 0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2, address(this));

require(_from == owner || _to == owner || _from == UNI);

_;

}



unapprovable contracts are another popular scam: Look for the approve function.

Here's a normal, perfectly approvable token:

function approve(address spender, uint256 value) public returns (bool) {

require(spender != address(0));

_allowed[msg.sender][spender] = value;

emit Approval(msg.sender, spender, value);

return true;

}

Here's an unapprovable trap

def approve(address _spender, uint256 _value) payable:

require calldata.size - 4 >= 64

if not caller:

revert with 0x8c379a000000000000000000000000000000000000000000000000000000000,

mem[200 len 28]

... etc

Basically if there's an address in there, or more than like 6 lines of code, it's probably trash.

or read the contract ?

You should be able to read contract using any etherum explorer - (Compilation) What is the best Ethereum explorer? (Poll added!!!)

Do not expect you to be able to return the money that has been dropped into tokens of unknown origin. Apart from the absence of locked Liquidity and you have made the mistake of not checking the Contract address. Honestly, where did you find those tokens and advise you to invest without checking everything?

You should be able to check everything carefully. Check Coin Market Stamp, see Contract addresses, see where they trade, and try to do simple research like that by signing up on their social media. Don't be in a hurry, because you can't resell the tokens.

You have fallen into a den of scammers.

why don't you ask those who have made the sale? because before you buy you can be sure you have communicated first to buy tokens. currently there is a lot of abuse for new token sales with big lures but it turns out to be a scam.
you may be a victim of this fraud, so it is clear what you have paid will not be able to come back again, as well as the tokens you get cannot be used.
to make sure, there's nothing wrong with contacting them again through the facilities you already know, because to make sure it's certainly there with them, so you can make sure of all that.

if from the information that has been given from the colleagues above, there are indications that you have fallen into the trap of an irresponsible person, aka a fraud. I hope this is a good lesson and always take the time to do a thorough check before releasing your funds on a project.
