Avalanche flash loan exploit sees $371K in USDC stolen

Avalanche-based lending protocol Nereus Finance has been the victim of a crafty hack that saw a user net $371,000 worth of USD Coin (USDC) using a smart contract exploit.

Blockchain cybersecurity firm CertiK was one of the first to detect the exploit on Sept. 6, indicating that the attack impacted liquidity pools on Nereus relating to decentralized exchange Trader Joe and automated market maker Curve Finance.

CertiK also suggested that underlying protocols themselves were impacted, however, Curve Finance responded via Twitter on Sept. 7, stating “maybe you meant ‘assets impacted,’ not ‘protocols impacted’. Only @nereusfinance and its assets seem impacted.”

On Sept. 7, Nereus Finance released a detailed post-mortem of the incident explaining an “exploiter” was able to deploy a custom smart contract that utilized a $51 million flash loan from Aave to artificially manipulate the AVAX/USDC Trader Joe LP (JLP) pool price for a single block.

Thanks @peckshield @CertiK

As a result, the anonymous hacker was able to mint 998,000 worth of Nereus’ native token NXUSD against $508,000 worth of collateral. They then swapped this capital into different assets via various liquidity pools and managed to walk away with a net profit of $371,406 once the flash loan was returned. 

The incident ended with to the creation of $500,000 of NXUSD “bad debt” in the NXUSD protocol.

The Nereus team says it was quick to remedy the situation; after consulting security experts, developing a mitigation plan, and notifying law enforcement, they liquidated and paused the exploited JLP market.

The bad debt was reportedly paid off using NXUSD from the team’s treasury.

According to Nereus, the exploit resulted from a “missed step” in the price calculation, resulting in the opportunity to be exploited. However, it stressed that “no users funds are at risk, and NXUSD continues to be over collateralized” and the “Lending and Borrowing protocol was not affected by this exploit.”

Nereus is also confident the same exploit won’t be possible a second time, as the team will be  amending its “audit and security practices in order to ensure these types of events do not occur in the future,” noting:

“While this exploit is a bad incident — it’s not uncommon for protocols to face these types of battle tests.”

As of this writing, the Nereus team is trying to identify the hacker and track the funds and has offered a 20% White Hat reward for the return of the funds, no questions asked.

Despite this recent flash loan exploit and several other notable incidents throughout the year, CertiK’s August 2022 Monthly Skynet Alerts Report, released on Sept. 2, claims there has been a notable decrease in these types of attacks.

Compared to the previous month, August saw a drop of 95% in flash loan attacks, only resulting in a total loss of $745,244, the second lowest this year.

February still has the lowest recorded loss from flash loan exploits with only $200,000.

4 On-Chain Metrics Show the Bitcoin Price Is Primed for Bullish Explosion

4 On-Chain Metrics Show the Bitcoin Price Is Primed for Bullish Explosion

Amid recent macroeconomic extremes, Bitcoin has maintained a quiet stance, almost eerie for its HODLers. Nonetheless, its hashrate and accumulation are soaring — what could this mean for its price?

Bitcoin has been consolidating in a narrow range between $18,800 and $20,200 since the mid-Sept price fall. In volatile markets like cryptocurrency, similar quiet periods of consolidation are rare. 

Recent Glassnode findings show that the current BTC price action resembles both pre-crash November 2018 and pre-rally March 2019. Despite price downturns, mining and accumulation statistics are improving. Let’s look into what this means for the health of the network.

Bitcoin hashrate makes new ATH 

Last week, the Bitcoin hashrate made a new all-time high of 242 exahashes per second.

In the chart below, we can see that Bitcoin’s longer-term, slower hash ribbon was once again overtaken by the faster ribbon, indicating improved mining conditions in late August. Since the price saw no major uptick during this time, the rise in hashrate was likely due to more efficient mining hardware and more mining rigs working in general.

Historically, these hash ribbon moving average swaps precede price gains. Historically, when the hash-rate drops and subsequently recovers, major BTC price bottoms have been made. 

Is a price bottom in?

Apart from the hashrate, Bitcoin accumulation levels also reached a 7-year high. CryptoQuant data shows that 6-month-old and older Bitcoins now make up 74% of the realized cap. During the 2019 and 2015 bottoms, this score sat at 70% and 77%, respectively.

Lastly, for the first time in this cycle, the percentage of supply in loss has reached the 50% level.

CryptoQuant data shows that the price bottoms during previous cycles normally occur when the percentage of supply in loss reaches 50% or more.

The current data shows the highest percentage of losses at 52% on the daily chart, 50.4% on the weekly (7DMA), and 48% on the monthly (30DMA). 

While quite a few metrics suggest that BTC should be near a bottom, the overall momentum will likely still depend on macroeconomic conditions as well as its correlation with the Nasdaq and S&P 500.

Multi-week dollar lows fuel Bitcoin bulls

Data from Cointelegraph Markets Pro and TradingView showed BTC/United States dollar climbing prior to the Wall Street open, up over 5% in 24 hours.

The pair had shaken off macroeconomic concerns at the start of the week, with trouble at Credit Suisse and the escalating Russia-Ukraine conflict failing to slow performance.

Now, the short-term analysis focused on a run potentially topping out closer to $21,000 — as was the case late last month, as sell-side pressure at that level remained significant.

“20500-21000 is a sell zone. If price gets there, which should, don’t be too bullish,” popular trader Il Capo of Crypto told Twitter followers on the day.

Razzoorn, an analyst at international trade group The Birb Nest, noted that the current charge was Bitcoin’s fifth attempt at escaping a major liquidity cloud in several weeks.

Despite the potentially limited upside opportunity, Bitcoin rallied in line with a broader risk asset tide which saw United States equities finish noticeably higher the day prior.

At the same time, the U.S. dollar suffered, the U.S. dollar index (DXY) extending losses to approach 111 points and threaten support in place since mid-September.

“Up the market goes,” a more optimistic Michaël van de Poppe, CEO and founder of trading platform Eight, continued:

“Flipping $19,500 for support. Now, if range-high at $19,600 holds for Bitcoin, I assume we’ll continue towards $22,400.”

Altcoins attempt to change sticky trend

Across major altcoins, it was Ether (ETH) and Ripple (XRP) leading daily performance at the time of writing.

XRP, on the other hand, faced a more stubborn band of resistance after prior gains, bouncing off multi-week support just below $0.45.

McDonald’s starts to accept Bitcoin and Tether in Swiss town

Multinational fast food chain McDonald’s started to accept Bitcoin (BTC) as a payment method in the 63,000-populated city of Lugano in Italian Switzerland, which is becoming a hotspot for crypto adoption in Western Europe. 

A one-minute video of ordering food on McDonald’s digital kiosk and then paying for it at the regular register with the help of a mobile app was uploaded on Twitter by Bitcoin Magazine on Oct. 3. The Tether (USDT)  logo could be spotted next to the Bitcoin symbol on the credit cash machine, which is not surprising, as in March 2022 the city of Lugano announced it would accept Bitcoin, Tether and the LVGA token as a legal tender.

On March 3, 2022, the city signed a memorandum of understanding with Tether Operations Limited, launching the so-called “Plan B.” According to this plan, Tether has created two funds — the first one is a $106 million, or 100 million Swiss francs, investment pool for crypto startups, and the second is around $3 million, or 3 million Swiss francs, attempt to encourage the adoption of crypto for shops and businesses across the city.

In addition to allowing Lugano residents to pay their taxes using crypto, the project will extend payments to parking tickets, public services and tuition fees for students. More than 200 shops and businesses in the area are also expected to accept crypto payments for goods and services.

Speaking to Cointelegraph in June, Paolo Ardoino, chief technology officer of Tether and Bitfinex, claimed that Plan B “is going great,” announcing a two-week educational activity on blockchain and cryptocurrencies in the city.

In September 2021 El Salvador became the first country in the world to allow using Bitcoin as a legal tender. Since that time, McDonald’s has been accepting Bitcoin at all its 19 outlets in the country.
