Crypto Wallet Says It Offers 1,000 EOS Accounts for Free

A crypto wallet says it is giving away 1,000 free EOS accounts to users on a first-come, first-served basis.

A crypto wallet provider says it has launched a giveaway that allows 1,000 users to get a free EOS account.

Lumi Wallet notes the giveaway is taking place on a first-come, first-served basis. Instead of answering quiz questions, preparing a submission or entering into a lottery system, all that participants need to do is sign up in EOS for free. The promotion will end when all of the accounts have been snapped up.

The company says the giveaway is in partnership with Minergate and Changelly, and comes as Lumi vies to become “the premier wallet for the EOS blockchain.”

Lumi has been integrating blockchain into its ecosystem for a while, and in a previous update, the EOS coin was made available in its wallet for the first time.

Diana Furman, the CEO of Lumi Wallet, said: “We decided to make the registration for our users fee-free. Firstly, because we want them to have an easier gateway to EOS. Secondly, because we really do believe that EOS is the platform to check out.”

The executive says she wants Lumi users to be able to explore what EOS has to offer without any barriers in the way, as the blockchain’s development continues apace.

As Lumi continues to align itself closer with the network, the platform is planning to integrate EOS-based tokens, support its decentralized applications (DApps), and implement the EOS voting system within the wallet. To benefit from the giveaway, all users need to do is download the Lumi Wallet app and set up an EOS account for free, the team says.

More tokens supported

Lumi Wallet is available for Android and iOS devices, and currently supports bitcoin, ether, bitcoin cash and most ERC-20 tokens. The company says it strives to ensure that transactions performed through its platform remain completely anonymous, with its team taking great care to ensure the software has an eye-catching design.

Lumi Wallet is available here

New tokens are being added all the time. Earlier this month, Lumi Wallet revealed that more than 900 ERC-20 tokens are now supported — making it easier for users to swap between a range of crypto assets whenever they please.

Lumi is now preparing for its next big step: In the summer, the company is planning to go open-source. According to its team, this upgrade has been much anticipated since it was initially launched.

Game on

The platform also offers a devoted wallet for collectibles, enabling gamers to keep all of their assets and ERC-721 tokens in one secure place. The app is mobile-focused, eliminating the need for players to use special browsers or web extensions in order to access their collectibles.

Lumi Collect has been continuing to add immediate access to blockchain games directly from the app itself — and last month, My Crypto Heroes joined the platform. According to a blog post written by Lumi at the time, the title is one of the largest Ethereum-powered games in terms of volume.

The company says it is poised to capitalize on the “great leap” that is about to be seen in the modern gaming industry. As increasing numbers of players turn to blockchain to see what this technology has to offer, gaming formats are going to change — as will attitudes toward assets.

Crypto Exchange Changelly Confirms It Can Steal Users’ Monero (XMR)

Changelly Can Withhold XMR If KYC Isn’t Completed 

Privacy coins, such as Monero (XMR), ZCash (ZEC), Horizen (ZEN), are often the topic of controversy within the cryptocurrency community, as some naysayers claim that these assets directly enable money laundering, terrorist financing and the like. Although this may be true in rare, fringe cases, these critics fail to remember that a good majority of privacy coin-enabled transactions are likely made with good intentions.

Regardless, Changelly, a Prague-based ‘instant’ cryptocurrency exchange, has recently sought to restrict

Monero (XMR) trading on its platform, even though it has natively supported the privacy coin for months, if not years.

For individuals looking for near-instant crypto-to-crypto transactions, Changelly is undoubtedly one of the best places to go-to, but for those looking to trade their assets into Monero specifically, using the service may pose a bigger problem. Over the past few months, a multitude of users have taken to Reddit to claim that Changelly withheld hundreds of Monero due to “high risk” KYC concerns.

As reported by The Next Web, a Changelly representative has since confirmed that the service is allowed to have a finger over the trigger, which allows the exchange to withhold “suspicious transactions” that involve Monero. He/she wrote:

To all Monero community, our risk management system doesn’t mark all transactions out of the blue… Monero is the crypto that hides a sender and recipient thus making transactions untraceable. This [is] a reason why big amounts of other currency got to be checked [sic] before [it’s] converted to XMR.

The spokesperson went on to add that Changelly does not inherently hate users who use XMR but will restrict transactions in accordance with its rather strict KYC procedure, as fears of money laundering run rampant within global regulatory bodies. The company representative also added that as soon as the proper KYC protocol is fulfilled, the funds will immediately be released to the predesignated consumer-owned address, and the said user would even be whitelisted to avoid such an occurrence from happening again.

On the other hand, however, it was unfortunately revealed that if the submitted KYC documents are not up to par, Changelly retains to right to keep all of the withheld cryptocurrencies for an undisclosed period of time.

Regulators And Privacy Cryptos — Not A Good Combo

As reported by Ethereum World News in mid-May, Japan has taken a risk-averse stance towards privacy cryptocurrencies, with regulators within the country requiring local exchanges to delist Monero, Dash, ZCash, and other anonymous blockchain-backed assets or face delicensing.

For now, Japan is the only ‘big name’ country to have made a move against privacy-centric digital assets, but many believe that it won’t stay that way for long, with pessimists speculating that countries around the globe will eventually make their move against this subindustry.

Decentralized Crypto Exchange Bancor Reports ‘Security Breach,’ Remains Down for ‘Maintenance’

Decentralized cryptocurrency platform Bancor halted operations Monday, July 9, as it investigates what it calls a “security breach,” reportedly involving over $12 mln.

A Twitter post confirmed the breach and Bancor’s halted operations, which the platform says is specifically to allow investigative work prior to a full statement being released “shortly.”

“This morning (CEST) Bancor experienced a security breach. No user wallets were compromised,” the tweet reads, continuing:

“To complete the investigation, we have moved to maintenance and will be releasing a more detailed report shortly. We look forward to being back online as soon as possible.”

As of press time Monday, the platform’s homepage redirects to a maintenance message, with provision for a return to normal service within “minutes” rather than hours or longer.


User funds remain intact due to Bancor not holding any cryptocurrency in hot wallets or otherwise on their behalf.

The malicious party exchanged some of the tokens via instant conversion service Changelly, the latter told Cointelegraph.

“Part of the stolen tokens were exchanged via Changelly,” CEO Konstantin Gladych told Cointelegraph in a statement, adding:

“Afterwards the tokens were frozen by the Bancor Foundation in our contract. Now we are helping track the stolen funds.”

Sources familiar with the matter also told Cointelegraph that the stolen tokens included Bancor’s native token BNT –– which the platform was able to freeze –– as well as around 25,000 Ethereum (ETH) ($12.2 mln) and 300,000 Pundi X (NPXS) ($1,200), which Bancor is in the process of tracking, reportedly with the help of other exchanges.

Bancor became well known after raising $153 mln in ETH in three hours during its Initial Coin Offering (ICO) in 2017, an unprecedented amount at the time.

Its decentralized structure has contributed to its security record, while major hacks have continued to rock centralized cryptocurrency exchanges – most notably Coincheck – throughout this year.

Vitalik Buterin, co-founder of Ethereum, delivered heavy criticism of centralized exchanges last week, saying he “hopes they burn in Hell.”

Crypto Exchanges Pause Services Over Contract Bugs

As many as a dozen or more ethereum-based ERC-20 smart contracts have been found to contain bugs that let attackers create as many tokens as they want.

While the bugs – first identified on April 22 and April 24, respectively, in a pair of posts published by a group called Coinmonks – aren’t tied to the ERC-20 standard itself, the issues prompted a number of exchanges to suspend ERC-20 tokens as they investigate. Those exchanges included OKEx, PoloniexChangelly, Quoine and HitBTC.

Huobi.Pro separately announced on April 25 that it had suspended all coins, but has since limited that to ERC-20-based tokens. As of press time, Poloniex has moved to reinstate services for ERC-20 tokens.

In one example, an attacker transferred 57,896,044,618,658,100,000,000,000,000,000,000,000,000,000,000,000,000,000,000.792003956564819968 BeautyChain Tokens – as shown by transaction data on Etherscan – on April 22, a development that prompted the initial investigation into the issue.

“Our study shows that such transfer comes from an “in-the-wild” attack that exploits a previously unknown vulnerability in the contract. For elaboration, we call this particular vulnerability batchOverflow,” Coinmonks’ post on the 22nd explained. “We point out that batchOverflow is essentially a classic integer overflow issue.”

Countless coins

The batchOverflow post outlines how the batchTransfer function in a contract has a maximum number of tokens that can be sent in a transaction, adding that the value of the tokens being transferred must be less than the total number of tokens that were generated. However, the “_value” parameter – one of the two that determine the total number of tokens – can be manipulated, which would then change another variable, resulting in an attacker being able to create as many tokens as they’d like.

Further, the attacker can bypass the barriers in the contract which would normally ensure that a reasonable number of tokens are being transferred.

“With amount zeroed, an attacker can then pass the sanity checks in lines 258-259 and make the subtraction in line 261 irrelevant,” the post explained, noting:

“Finally, here comes the interesting part: as shown in lines 262-265, the balance of the two receivers would be added by the extremely large _value without costing a dime in the the attacker’s pocket!”

While initial reports indicated all ERC-20 tokens may be impacted, the “batchTransfer” function is not part of the token standard.

The Medium post did not list the vulnerable projects, though it did note that the BeautyChain was the first project they discovered. In a sign of the seriousness of that bug, OKEx said on April 24 that it was rolling back trades on the BeautyChain Token.

The exchange also announced around that time that in light of the bugs, it was suspending desposits and withdrawals a project called SmartMesh trading due to “abnormal trading activities.” Coinmonks and author Ranimes noted that this was possibly due to the proxyOverflow bug, which, like batchOverflow, is a classic integer overflow problem. Certain variables can be manipulated to spontaneously generate large amounts of tokens.

One Twitter user noted that an attacker created $5 octodecillion in SmartMesh tokens.

As one of the posts noted, the danger exists that someone can use a vulnerable cryptocurrency to manipulate prices in their favor by trading with bitcoin, ether or another trading pair.

Representatives for the BeautyChain and SmartMesh projects did not immediately respond to requests for comment. However, a statement on BeautyChain’s website acknowledges the bug and states that trading will resume at an undetermined point in the future.

Similarly, SmartMesh announced that it would take steps to prevent price manipulation, saying:

“The SmartMesh Foundation will take the equivalent amount of SMT to the counterfeit amount and destroy it to make up for the losses caused, and keep the total supply of SMT at the value of 3,141,592,653.”

$200 Bln Market Cap, $10 Bln Day Trading: How Far Can Crypto ‘Vortex’ Go?

The trading frenzy following Bitcoin’s push to $7,500 is in full swing with almost $10 bln changing hands in 24 hours.

Data from Coinmarketcap shows a combined $9.2 bln flowing through exchanges tracked by the resource since Thursday.

The global cryptocurrency market cap is now over $200 bln, a new record, with Bitcoin accounting for $125 bln.

The market cap news influenced proponents of the digital currency more strongly, with evangelist Trace Meyer describing it as a one-of-a-kind wealth transfer. He told the audience in a lecture at LaGuardia Community College in New York this week:

“This vortex that’s just going to suck in so much of the world’s capital… it’s going to be a wealth transfer the likes of which humanity has never seen and probably won’t ever see again for a long, long time.”

Commenting on the price and volume growth, instant conversion platform Changelly told Cointelegraph the prospect of the SegWit2x hard fork was the more dominant factor influencing markets.

“We suppose that the possible Bitcoin hard fork is the key reason of the tremendous uptick… In order to get extra coins, investors buy more BTC and exchange so-called altcoins to BTC, causing enormous demand,” CEO Konstantin Gladych said.

“We’ve seen 3x increased demand on buying Bitcoin for the last few days on Changelly.”

Altcoin markets have tumbled with Bitcoin’s rise, many reaching lows not seen for several months, Cointelegraph reported Thursday.
