[Ethereum] Is that a serious bug

bugmyetherwallet

I am trying to store and send some ERC20 tokens from myetherwallet.

  1. My wallet does not show me the right balance of tokens.

  2. When trying to send those tokens to another Ethereum address (that I specify), what is broadcasted to the blockchain is a tx to a different address.

I am getting 2 error messages:

  1. Transaction execution error

    (from MEW, but I am not prevented from generating and sending the tx)

  2. Warning! Error encountered during contract execution [Bad instruction]

    (from Etherscan)

My wallet does not show me the right balance of tokens

The MyEtherWallet node was under a lot of strain and it is advised to switch node in the top right. If you're just looking at your balances, use a block explorer so you don't expose your private keys.

When trying to send those tokens to another Ethereum address (that I specify), what is broadcasted to the blockchain is a tx to a different address...

This is because you make a transaction to the contract address and invoke a function transfer() which takes 2 parameters (the amount of tokens to transfer and the address to transfer to).

Function: transfer(address _to, uint256 _value) ***

MethodID: 0xa9059cbb
[0]:000000000000000000000000280c699961d44592c1655be22c272b4c0cfc4a06

The above tells the contract to transfer KC tokens to address 0x280c699961D44592C1655be22C272B4c0cFc4a06.

"Transaction execution error"

This is a report that the transaction failed to complete - see below.

Warning! Error encountered during contract execution [Bad instruction]

This is because a condition in the contract did something to kill execution. Without reading the contract, I'm unsure what that is.
