Ethereum Exchange’s Attempts to List ETC Leads to Losses

Yunbi, one of China’s biggest Ethereum trading exchange, announced today that they were to postpone the listing of ETC in order to undertake “security preparations” to address vulnerabilities due to “Relay Attack.”

Yunbi further stated that they had lost over 40,000 ETC “from users who deposited ETH before YUNBI listing ETC after Hard Fork:”

“The major reason of this lost is due to “Relay Attack” during the hard fork. YUNBI will not be responsible for this lost.

After YUNBI lists ETC, please make sure you use the correct address to deposit your ETC and ETH.”

Speaking to CCN, the relay attack was described by Péter Szilágyi, one of Ethereum’s core developers, who said:

“Think of transactions [as] an authorization to take X funds off your account. This authorization is simply a digital signature which currently is valid on both chains. So if you have funds on both chains, the signature can move those funds on both chains.”

This vulnerability was well publicized prior to the fork leading some to suggest that the existence of two chains would not be viable as transactions can be replayed. However, Poloniex listed ETC regardless, with other exchanges following, including Kraken, Bitfinex and Yunbi.

Gdax and CHBTC, China’s biggest ETH exchange by trading volume, have stated that they will not list ETC, but will allow their customers to withdraw ETC if applicable. Coinbase will likewise not add any ETC functionality and since ETH was added to Coinbase after the hardfork, there are no ETC to allocate.

The vast majority of Ethereum’s community has shown support for the forked chain with ETH’s price remaining relatively stable while the overall ETH plus ETC marketcap has increased considerably after the fork and after Poloniex’s ETC listing, with ETH holders being more than 30% richer since the hardfork. Furthermore, the Ethereum Foundation which employs countless of experienced developers working on sharding, Casper and other applications has come out in support of ETH:

We will focus our resources and attention on the chain which is now called ETH (ie. the fork chain)

Ethereum users and dapp developers can, therefore, fully ignore ETC and be safe from relay attacks if they transact on only one chain allowing the two communities to freely co-exist and compete in their chosen path.
