Ethereum 2.0 and stalked pool
There are great expectations for the new Ethereum 2.0. The expected launch of Ethereum 2.0 will happen very soon. Also, the up-gradation will happen from the existing Ethereum network to the new Ethereum 2.0. The new ETH 2.0 comes with a lot of hope and promise. It will reduce network congestion. It will also come at a lesser cost. But there is a small problem here. Before the ETH 2.0 launch, the users have to lock or stake their ETH tokens in a smart contract. The use or 
movement of these tokens will not possible till the up-gradation is complete.
Curve Finance launched a new innovation. This technology will be helpful, during the up-gradation from ETH 1 to ETH 2.0. It will be easy for the users to support both the networks during the upgrade. Till now, the amount stalked in Ethereum 2.0 is tokens worth $2 Billion.
The process
The process starts with Lido’s stalking service. It got launched in October. With this service, the users will stake the ETH tokens and will receive stETH tokens. stETH tokens will be an asset of equal value as the ETH tokens. In this way, the users will stake the ETH tokens and as well as use them.
Lido got funding in December. It was able to raise $2 million. In addition, it got funding from venture capital firms. It also got help from Defi investors. Stani Kulechov of Aave lending protocol also funded Lido. Kain Warwick of the derivatives protocol Synthetix also supported Lido.
The problem
stETH tokens are the same in value as ETH tokens. However, all the protocols are not designed in a way to handle the new stETH tokens. So, the stETH holders will not be able to utilize all the finance applications in the same way as Ethereum. Few automated financial protocols will not support stETH tokens. these are issuing loans, swap between digital assets, and gaining interest on deposits.
The possible solution
Curve Finance is famous for its cost-effective swap technology. It helps the users to swap between digital currencies and other assets seamlessly. Recently, Curve Finance announced the launch of a new trading pool. 
This pool will support the swap between native ETH tokens and stETH tokens. Due to this, the users will be able to swap between the ethereum tokens with the least cost. So, the stETH holders can utilize all the finance applications in Defi. They will also be able to stake the ETH tokens for the upgrade to ETH 2.0 version.
This new Curve pool is an important part of the Ethereum development. All people interested in the development of the Ethereum blockchain will welcome this step. This will provide the users to utilize the tokens in both ways. The users can stake the tokens till the upgrade. Also, in the meantime, they will be using the tokens for all Defi applications. This is definitely a remarkable step in the crypto world. This technology will ensure the users to trust in the development of cryptocurrencies.

The findings
ZenGo is a prominent cryptocurrency mobile wallet maker. Zenco did some researches in the crypto world. It found new observations in the Ethereum dark market. The research highlighted front running bots are spying on Ethereum transactions. Front running bots are nothing but malicious software. These bots are spying on other peoples’ transactions, specifically doing Ethereum transactions. 
This is basically for making huge profits at other’s expense. This may create gains for a few people. On the other hand, it will impact many authentic people badly, creating huge losses. So, the advice for developers is to build more secure systems.

One famous example is the exchange bids. Let’s explain this with one example. If someone is buying a huge amount of ETH on any cryptocurrency exchange. This incident can trigger a huge fluctuation in the price of ETH. The price of ETH will go up immediately. Another person, who is monitoring this activity, will purchase ETH at a lower price. When the price will go up, he will sell this token at a higher price. In this way, he will make a large number of profits. Apart from this, there are many other ways to make profits. They are liquidations, buying rare NFTs, or user mistakes.
Studying the bots’ behavior
ZenGo carried out an experiment to understand the behavior of bots. The researchers trapped a few bots and locked them with cryptocurrency. After that, they studied their way of functioning. They tried to know how the bots are capturing the bait and how perfectly it is doing that. In addition, they also checked the probability of the success rate of this bait. They also experimented with ways of escaping the bots and not getting into their trap.
One of the first traps found was worth ETH 0.035 (USD 21). The time span is three minutes. Another incident found was for ETH 0.055. This was a different bot and it got completed only within few seconds. Lastly, an ETH 0.05 trap got created. Luckily, the researchers were successful in extracting all the funds. There are more sophisticated bots present in the crypto market.
Eminent personalities’ opinion
Dan Robinson and Georgios Konstantopoulos are prominent Defi investors. They highlighted the various 
attacks on the Ethereum blockchain by bots. They also focused on the consequences of these attacks by bots.

He conducted research about the front running bots trapping Ethereum transactions. Also, he mentioned that this activity is not something new on the Ethereum blockchain. He added that the reality is they are looking for bots that could possibly make some profits. It is easy to fall prey to such baits for higher returns. He emphasized that front runners are actually more prominent than one may think. According to him, it is possible to avoid these front-running bots but it is not at all easy to escape them. Each and every bot functions in different ways. Moreover, different factors trigger the transaction. There is a competition among the bots themselves to gain the highest bait. Lastly, he specified that this is only the tip of the iceberg. There is a whole new world of bots running the Ethereum blockchain transactions.
