OKEx To List Four New Stablecoins In Coming Days

Continuing the whirlwind of news for stablecoins, OKEx announced today that it will list four new stablecoins on its platform, just as the largest and most controversial stablecoin, Tether (USDT), experiences huge price volatility.

The Malta-based exchange will list Paxos Standard Token (PAX), USDC//Coin (USDC), True USD (TUSD), and the Gemini Dollar (GUSD), all to begin trading within the next couple of days. The announcement comes only hours after Kucoin, another well known crypto-asset exchange based in Hong Kong, temporarily suspended and then resumed transfers of Tether tokens on its platform, citing “wallet system maintenance”.

Tether Action

The price of USDT fluctuated wildly today, and caused BTC/USDT pairings to trade at record-high premia, owing to the divergence in price between USDT and genuine fiat U.S. dollars. The difference in bitcoin price on USDT exchanges versus the Coinbase exchange, which does not use USDT, exhibits the effect of Tether price premia.

Due to the outsized role Tether plays in underpinning the crypto-asset industry, today’s market turmoil has been cautiously attributed by some to issues surrounding Bitfinex and Tether, which are closely linked through common management and investors and based together in Hong Kong.

Specifically, Bitfinex and Tether have been moving from bank to bank to bank over the past year, after being “dumped” by the Wells Fargo & Co bank, following subpoenas by the U.S. Commodity Futures Trading Commission over accusations that Tether could not back up its virtual currency with the equivalent amount of fiat.

As CryptoGlobe recently explored, Tether has been generally controversial in the crypto-asset industry for some time, serving as a linchpin for liquidity on many exchanges while never actually accomplishing a legal audit, and thus never proving its tethers are backed by real dollars.

All four of the new stablecoins listed today by OKEx differ from Tether in that they have to date experienced no banking problems, while three of them - GUSD, PAX and USDC - are regulated.

The Gemini exchange’s GUSD has been criticized, however, for having the ability to completely halt or reverse transactions of its ERC-20 stablecoin if Gemini so chooses, or is obliged by law enforcement to do so.


Liquidators Take Charge of Cryptopia: Here Are Cryptopia’s Big Mistakes

He has been working as a freelance chain analyzer and as a technological content writer for whitepapers etc. In his spare time, he likes to write about topics that involve Bitcoin, Blockchain and cryptocurrencies.

Although cryptocurrencies themselves are incredibly secure, the exchanges that facilitate their movement have been far more problematic.

2018 set a record for the most crypto exchange hacks in history, and the efforts of bad actors are becoming more expansive and more expensive with time. Now, another crypto exchange has been brought down by a hack.

The Slow Descent of Cryptopia

The New Zealand-based Cryptopia endured a hack on January 14 that cost the company $16 million worth of digital assets including Ether and ERC-20 tokens. In the immediate aftermath of the breach, Cryptopia took its site offline posting a message indicating that the website was under maintenance.

At the same time, Cryptopia contacted police authorities who worked to identify the perpetrators and to attempt recovery of the stolen assets. A few days later, the company acknowledged the data breach and admitted that they incurred “significant losses.”

Eventually, Cryptopia came back online, providing trading limited trading opportunities while continuing to experience banking issues. This reduced functionality prevented many users from cashing out their tokens.

For a while it seemed as if it is going to recover from the hack. However, after making efforts to reduce costs and develop a profitable business model, Cryptopia decided that it was in the best interest of all stakeholders to liquidate the exchange. In a statement, Grant Thornton, Cryptopia’s assigned liquidator, conveyed their intention “to find the solution that is in the best interests of customers and stakeholders.”

Take Note of the Mistakes

In some ways, Cryptopia made many correct moves in attempting to repair their exchange after such a significant breach. However, the mistakes made prior to it were ones that can’t be overlooked.

Mistake #1 – Exchange Security

Obviously, whenever a crypto exchange is hacked, there is well-deserved scrutiny of its cybersecurity practices.

In this case, it’s speculated that the exchange stored users’ private keys, the most prominent line of defense again an intrusion, on a single server that was vulnerable to a hack. In this scenario, hackers could easily access and record users’ private keys and then delete the information, making it inaccessible to users and to the exchange.

It’s estimated that hackers gained access to 76,000 different wallets, and, according to analysis, “none of which were smart contracts“. Without access to their accounts, Cryptopia was powerless to stop hackers from draining funds from the exchange.

“What surprises me the most is the negligence in relation to the security of the entire chain of work with the exchange's wallets.” noted Serge Vasylchuk, CEO of CODEX Exchange. “It was possible to prevent a hack for Cryptopia if they would take three must-have measures seriously. First, to ensure maximum isolation from external influences and from accidental internal interference. Second, to backup private keys on a regular basis, on a well-protected physical copy”.

CODEX has been effusive in their security efforts. After deploying multi-stage security audit to ensure the integrity of their users’ accounts and funds, it received a 10/10 security rating from Hacken security team, CoinMarketCap's data accountability and transparency partner. It may be expensive, but it’s necessary for protecting digital assets, something that is critical in crypto markets.

To put it simply, the Cryptopia hack was predicated on lax security standards, and it could have been avoided or greatly diminished if the company embraced industry best practices for guarding user and company accounts.

Mistake #2 – Poor Community Transparency

Of course, technological oversights, while frustrating, are bound to happen from time to time. However, crypto exchanges have full control over their response. They decide their level of transparency and community investment, and their decisions in this regard can have cascading consequences.

Most notably, the company began by issuing a false statement to users. The website was not undergoing “unscheduled maintenance,” a misleading statement that is becoming a code for more problematic events.

While Cryptopia rightly contacted authorities to report criminal activity, the company’s updates were few and far between, leaving their users and the greater internet to speculate about the event and the state of their holdings.

Finally, when the exchange eventually relaunched, it was mostly unusable, appearing in a “read-only” format that prevented users from actually accessing the platform’s functionality.

Communication is always a choice, and exchanges that choose not to fully inform their userbase are doing them and the greater crypto community a disservice. “Of course, after such negligence it is difficult to tell users about the funds lost,” added Vasylchuk. “but the lack of timely communication only worsens the situation when there are people waiting for explanation.” 


Crypto exchanges are a crucial part of the digital currency ecosystem. Investors and traders need to be able to trust them and their ability to protect digital assets.

Cryptopia’s liquidation adds it to the list of exchanges that have misbehaved and have been punished for their actions.

Of course, it doesn’t have to be this way. Exchanges can learn from these mistakes. They can prioritize and enforce robust security standards while emphasizing transparency and communication throughout the process.

It’s the only way forward, and it’s one that exchanges need to learn now before they are the next ones making the news.
