Hi guys,

time ago I had a problem withdrawing Ether from Bitstamp sending them directly to my ETH Binance address, they didn't show up for days and they had to manually "unlock" them because they don't support the way Bitstamp sends Ether. Now I was going to withdraw some other Ether from Bitstamp and this advise popped up:
WARNING: Do not send funds directly to exchanges which do not support smart contract deposits. Either check with the destination exchange first or send your funds to your private wallet.

Which is exactly what happened to me weeks ago, but at that time there was no warning.

So now I was wondering if there is a list or if anybody knows which exchanges support the smart contract deposits, in order to avoid this problem again.

Thanks!

Instead of sending your ETH from exchange to exchange, why dont you send all of them back to your wallet and store them there, and then trade only the amount you need.

Its much safer than what you're doing.

Because until now I've never had that problem, and Bitstamp's withdrawal are free. Now of course I'm gonna send them to MEW and then I move them where I need, but I was curious to know if the same problem I had with Bitstamp -> Binance would happen with other exchanges as well ;)

I have the same issue, but with wex.nz. How long until you got your eth back? What did the exchange have to do?

I didn't get them back, they've been kinda manually unlocked by Binance, so after 3 days and after contacting them I finally received the amount I sent.
Now I noticed that Bitstamp warns you not to send ETH to exchange that don't support smart contract, before they didn't warn you. So keep in mind that you can have problems, the best way is to send them before to MEW and then to the other exchange.

Thanks for your respone.

Yes, I realize that now. It is so weird that there are apparently different standards where some addresses don't support smart contracts and others do (I thought the whole idea of ETH is smart contracts).

Anyway, I contacted WEX via their kayako support system, got a reply here from WEX Official, but not over there. Lets hope they can manually unlock them as well.

I just did exactly the same mistake today sending eth from bitstamp to huobi.pro. How long did it take for binance to recover your funds?

Thanks.

It took them around 2-3 days.

Same me with Huobi. Same question.
Hope you got it back.
Thank you.

Also made the same mistake with Bitstamp -> Huobi. It's been three weeks now and I'm still waiting for them to credit my ETH (Huobi support claim they have asked the tech team to manually do it but they can't give me an ETA as to when it will be done).

Will post here if/when it turns up.

Update: my ETH finally got credited. I sent the deposit from Bitstamp on 26th January and it was eventually credited on 28th Feb. Talking to Huobi support it seems they manually reconcile all smart contract deposits at the end of the following month in which the deposit was made.

Lesson: DO NOT deposit ETH directly to your Huobi account from another exchange account. Instead, convert to LTC or XRP and send it that way.

The problem is not Huobi, is the way Bitstamp sends the ETH, which is different from all the other exchanges. Anyway I don't understand why you should change ETH into XRP or LTC, and maybe in the meantime the price changes: you simply send them to your MEW wallet and then to Huobi, you pay only a few cents and 0 risks.

Bittrex, Binance, Bitfinex, Coinexchange.io, Coinhako, Coinpayments, Cryptopia, Exodus, Kucoin,  Koinex, Ledger, Liqui, SimplexFX , Bithumb and Huobi all don't accept smart contracts.


Send all smart contract payments to MEW or a personal wallet and then to an exchange - saves a lot of problems.


It has to do with how APIs from ICOs and Exchanges track deposits from the blockchain. A lot of exchanges do not accept smart contracts.

ICOs often send the tokens to the senders address. Which in the case of a smart contract is the contract address - so your tokens will be lost.

With a NORMAL transaction the ETH is sent from the senders address via the blockchain to the receiver address.

With a SMART CONTRACT  a 0 ETH transaction with instructions (code) is sent to the CONTRACT address. The contract address then executes a internal transaction (code) to the receiver address.

BTC, LTC and BCH do not have that function. Smart contracts are unique to Ethereum and Ethereum based coins.
