The Pyth Network oracle network had malfunctions on Monday (20). Among the problems, the main one was errors in asset prices.
For example, the oracle reported the price of Bitcoin (BTC) at US$5,402, eight times less than the actual market price. But that wasn’t the only problem. Pyth’s price feed also reported the share price of AMC cinema chain at $772 on September 15th and 17th. However, the actual price did not even reach $50, according to Yahoo Finance data.
Even the price of Dogecoin (DOGE) was in error, with Pyth pointing the cryptocurrency-meme at $0.88 on September 15th. On the same day, DOGE’s market price was just over $0.25.
Oracle “came out”
Pyth is an oracle that seeks to bring together traditional finance and blockchain-based applications. With recent failures, the service broke one of the main rules of the market: never release wrong data on asset prices.

Unlike services like CoinGecko, developers use Pyth’s data to price smart contracts in real time. It receives pricing data from companies such as exchange FTX and the trading platform. market maker Virtu Financial. Then Pyth uses its own software to show asset prices to traders and developers. The process takes place in real time.
Therefore, the price feed can trigger actions in decentralized finance (DeFi) applications, ie settlements. With wrong prices, investors run the risk of losing their guarantees and being liquidated. Naturally, Pyth’s mistakes have driven many traders crazy.
“Stellar work – your faulty oracle feed liquidated my position in Mango Markets. But none of you are going to take fiscal responsibility now, are you?”, complained the Trade Daddy user on Twitter.
The fiasco comes less than a month after Pyth was launched on Solana’s main network (SOL) with the explicit goal of bringing reliable data on-chain in milliseconds. Their offerings rightly include cryptocurrencies and traditional assets such as BTC and AMC shares.
A Pyth representative declined to comment. On Wednesday (22), the company published an analysis recognizing the pricing problems and explaining their causes.
“Several Solana programs that rely on Pyth prices were affected by this incident. The impact has been exacerbated by some programs relying on price aggregator feed without using trust,” the report said.
Pyth said its developers are making changes to avoid pricing errors in the future. There will be a testing protocol so that companies supplying data to the network can see how their data will be processed before sending it out as a final product.

$2.6 Billion Bug in Solana Program Library Disclosed: Details
Researchers from Neodyme, a boutique team focused on security audits, noticed a critical vulnerability in Solana’s codebase
In their latest blog post, crypto security researchers from Neodyme shared the design of an attack that may be profitable for “expensive” tokens integrated into Solana (SOL) ecosystem.
“One Lambo per hour”
As per the announcement shared in Neodyme’s social network and blog, its members noticed a bug in the token-lending contract of the Solana Program Library. As such, it affected numerous Solana-based DeFi protocols.
We recently discovered a critical bug in the token-lending contract of the solana-program-library (SPL). This blog post details our journey from discovery, through exploitation and coordinated disclosure, and finally the fix.— Neodyme (@Neodyme) December 3, 2021
Aggregated total value locked (TVL) at risk was over $2,600,000,000. The design of the hypothetical attack was quite simple: while depositing n fractional tokens, a user is able to withdraw n+1 fractional tokens.
With Solana’s native token, SOL, it will not be effective economically, as 1 Lamport (the smallest fraction of SOL, like Satoshi for Bitcoin, Wei for Ether and Drop for XRP) is only worth about $0.000000220.
However, for Ether and Bitcoin, this scenario can be very profitable. With some technical upgrades, the attack can be executed about 300 times per second. In this case, losses can be dramatic:
We can get this transaction included about 300 times per second, stealing $7500 per second or about $27 million an hour (that is one Lamborghini Huracan every minute).
In automated mode, this attack becomes profitable even for FTT and RAY tokens.
On Dec. 2-4, Neodyme’s representatives contacted a number of decentralized finance protocols (DeFis) on Solana, e.g., Larix, Solend, Tulip, Accumen, Soda and so on.
All teams fixed the bugs in their architecture. Yesterday, software engineer Jordan Audet-Sexton shared in GitHub that the issue is fixed in Solana’s main codebase as well.
Here’s What’s Next for Ethereum Rivals Solana and Avalanche, According to Analyst Nicholas Merten
Prominent crypto analyst Nicholas Merten is taking a look at two layer-1 digital assets stacked up against the Ethereum (ETH) trading pair.
In a new strategy session, the host of DataDash tells his 486,000 YouTube subscribers where he thinks smart contract platforms Avalanche (AVAX) and Solana (SOL) are headed.
According to Merten, it is better to compare both coins to ETH rather than the US dollar or Bitcoin (BTC) as Ethereum’s greater success in recent years makes it a better barometer than Bitcoin.
“If you’re really looking to see if your play is outpacing others in the market, you want to take a look against Ethereum. It is the second-largest cryptocurrency in this space and it has been outpacing Bitcoin around 380% to 400% in this cycle alone since 2019.
So we want to be able to find plays that are outpacing Ethereum because Ethereum is a really solid bet. It’s a really good medium-risk, medium-reward play.”
Looking at Avalanche, Merten says that a local top might be in for the AVAX against ETH after the altcoin’s massive rally in the last few months.
“Avalanche has done phenomenally well against Ethereum. If you take a look back here since August, it’s up 422% against Ethereum. Great rally, even after the [recent] pullback here…
When I look at this chart I definitely like seeing an asset that performs well against Ethereum, but each time it’s come up to this range [0.034 ETH or $139.21] historically, it’s been dragged down…
I think that again we might see some kind of repetition, or at least a revisit down to the previous support range [0.014 ETH or $57.32], which means that’s it probably going to go down a little over 35% to 40% against Ethereum. A pretty decent decline.
At time of writing, AVAX is down 1% on the day to $107.20.
As for Solana’s price action against Ethereum, Merten notes that the pair is flashing a bearish pattern after printing massive rallies in the last 18 months.
“But to be completely frank as a trader, Solana’s had many rallies in the past. It’s had one back here [from July to August of 2020], 336% rally in price. Then back here [December of 2020], if you want to take from the lows, in this case, 1,000% move, massive multiples in price.
We take a look here as well, from the recent rally here [August 2021] into September, very similar to history, a little over 350% to 400%. Not a bad rally.
But to be completely frank, we’ve been stagnant since September generally. The trend is starting to fade here. We don’t have that same momentum, and it’s seeing if it can hold out against Ethereum.
If you break below this range here [0.046 ETH or $188], I think it’s very favorable that Ethereum is going to start to outpace Solana as well as other major layer-1 plays.”
Solana is currently down nearly 10% and trading at $203.79.
Solana Price Analysis: SOL spikes to $170, swift retracement to follow?
- Solana price analysis is bullish today.
- Rejection was seen at $170.
- SOL/USD set to retrace previous loss next.

SOL/USD 4-hour chart: SOL looks to recover?
On the 4-hour chart, we can see bullish momentum returning for the Solana price action today as bears are finally exhausted.
Solana price saw strong bullish momentum push the price higher for most of the week after support was found around $185 last weekend. However, yesterday, SOL/USD peaked at $244, leading to a drop lower during the second half of the day.
Overnight, bearish momentum continued pushing lower, with the $185 previous low broken. Further downside followed in the morning as bears briefly touched the $170 mark.
However, from there, a quick reaction higher was seen this morning and is currently still in play. Likely we will see the Solana price action continue higher later in the day, as bulls are eager to regain some of the loss seen earlier.
Solana Price Analysis: Conclusion
Solana price analysis is bullish today as we saw quick rejection from the $170 mark this morning. Therefore, a new swing low has been set, likely leading to recovery over the next 24 hours.
