Hi all,

Quick question; about 12 hours ago I transferred Augur (REP) from Exodus Wallet to Bittrex.
After some time I saw the following error:


Contract 0x48c80f1f4d53d5951e5d5438b54cba84f29f32a5 (REP-Augur-OLD) 
 Warning! Error encountered during contract execution [Bad jump destination]

(tx ID: 0x7b7810584190cc5e20d0d768d5ff345cf68bf9ef9f4bca0bf31c9e7938076ee0)


REP never made it to Bittrex, and never went back to Exodus.

Does anyone have any idea where the REP is?
What the problem could be?
When (and if) I'll ever get it back?

Thanks in advance!

It's really unfortunate. It's almost impossible to have something like this.
My prediction may have been suspended.

https://medium.com/@AugurProject/serpent-compiler-vulnerability-rep-solidity-migration-5d91e4ae90dd


The REP contract and the contracts in development where written in the programming language Serpent. They used this language because they started before solidity became popular. As part of their development process they had the Serpent compiler audited and in the process uncovered bugs in the Serpent compiler that critically affected their ERC20 token in a way that would prevent transfers.

So in response they deployed a new contract for the REP token written in solidity and intentionally used the exploit they found to halt the original REP contract. If you have REP at an address you will have it at the same address in the new contract. You may have to tell your client to watch this new address for REP tokens or rescan for balances in some clients.

Hopefully when they Audit the Solidtity compiler they dont find bugs in it as well.

You also probably want to move this to the alt-coin section since it isn't bitcoin related and so shouldn't be here. Just FYI.

Thanks for replying, so if I understand right, you guys think it's an error on Bittrex' side?

I am able to withdraw REP from bittrex no problem. I have not tested deposits but presumably they have that sorted out as well. The error is in attempting to use the old REP contract to deposit with. It is no longer functional and will just throw wasting your transaction. You need to use the new address.

And how do I do this? Where do I find this new adress?

Right now the REP is not on Bittrex and also not in my Exodus wallet.
How do I get it back?

I posted a link to an article that explains the transition. If you had read that then you would have the new address. You can also get it by looking up REP on etherscan. You can also lookup your address in etherscan to quickly check if your REP is at the address.

If you want to know how to follow a token thats going to depend on what ethereum client you are using. I have never used Exodus wallet but a quick google says that you need to rescan your balances: http://support.exodus.io/knowledge_base/topics/my-balance-is-not-correct

If that doesn't work and your REP is not at your address on etherscan then you have ruled out the funds being at your address and you can move on to bugging bittrex. Etherscan has a tab for viewing all of the ERC20 token transactions, I would start by identifying the transaction of the old token contract or new where you sent the funds to the exchange address and include that in your support ticket. If there is no transaction and your funds are on the old REP contract and not on the new one you need to contract the Augur developers and see if they can help you: augur.net has a slack invite link or you could just make a reddit post in /r/augur. I doubt that this would be your problem, its most likeley that your funds are just not being shown by exodus. If it is exodus then you could contact their support or try and transfer your keys to a different client like myetherwallet.com mist or parity depending on the format of the keys, I dont know if its a regular json or if its a seed since I dont use exodus.
