ChainCatcher message, according to a proposal in the Aave governance forum, Aave is considering integrating a new Chainlink oracle aimed at redistributing profits from front-running trades back to users of DeFi protocols.On December 23, decentralized oracle provider Chainlink released Smart Value Recovery (SVR), an oracle service specifically designed to extract profits from Maximum Extractable Value (MEV) for the benefit of DeFi protocols. On the same day, Aave proposed to integrate SVR, "to reclaim MEV from Aave liquidations and return it to the Aave ecosystem."Aave stated that Chainlink's SVR is a service that sells "repurchase rights" and liquidation profits of Chainlink price feedback oracles through MEV-Share auctions. Aave estimates that SVR can capture about 40% of MEV profits, which can be redistributed to Aave DAO for the benefit of users.

ChainCatcher news, according to The Block, the liquid staking platform Marinade Finance on Solana is discussing a governance proposal to address malicious validator nodes and democratize MEV (Maximum Extractable Value).Marinade proposes a "balanced" approach that reduces harmful MEV while fairly distributing related profits through an open market. The proposal suggests establishing a public committee to oversee delegation activities and blacklist malicious validator nodes. Additionally, it recommends reopening public trading pools to prevent MEV flow concentration in a few private trading pools and proposes funding for MEV research to enhance transparency and data accessibility.Researchers point out that the current centralization issue of MEV is worsening, particularly with sandwich attack behaviors threatening Solana's decentralization. Marinade hopes to seek community feedback through the governance proposal and ultimately vote and implement based on the opinions received.

ChainCatcher news, Ethereum Foundation researcher Justin Drake posted on X that today marks the four-year anniversary of the Ethereum Beacon Chain's launch. In its initial phase, only 500,000 ETH were staked. Although it did not provide direct benefits to users at the beginning, it has gradually grown into one of the most powerful foundations in blockchain history.Looking ahead, Drake believes Ethereum has the opportunity to become the settlement layer of the value internet. Although the Beacon Chain is still not perfect, the upgrade path in the coming years will remain challenging, including improvements in censorship resistance and MEV handling, reducing staking deposits, increasing finality speed, smart issuance, achieving smartwatch-level full-chain verification, and post-quantum security. Additionally, outside the consensus layer, there is hope to achieve complete sharding in the data layer and native Rollup in the execution layer.Drake stated that many L1 improvements will be gradually released in the coming years, and enhancements like post-quantum security may require a complete redesign. L2 solutions will provide significant performance improvements within months, including fast user experiences, low fees, unlimited throughput, and synchronous composability.

ChainCatcher news, according to The Block, Jito Labs achieved a monthly fee revenue of $78.92 million in October, doubling the previous record of $39.45 million set in May. This growth has positioned Jito Labs ahead of Lido and Uniswap, making it the leading fee generator in the DeFi space.Jito Labs' earnings on October 24 were particularly remarkable, with a single-day tip revenue reaching $6.14 million, highlighting the growing demand for MEV (Maximum Extractable Value) services on the Solana chain. Jito Labs' success is attributed to its MEV infrastructure, including the Jito-Solana validator client and block engine, which effectively extract value from on-chain trading activities. Additionally, the JitoSOL staking token further diversifies revenue sources by combining staking rewards with MEV extraction profits.The rise of Jito Labs signifies a potential shift in the fee model of the DeFi space towards MEV optimization, but its sustainability may depend on high trading volumes on Solana, especially those driven by memecoin transactions.

If scammers claim that the code was generated by ChatGPT, users can use tools like ChatGPT or Claude to review the code and check for any malicious behavior.It is reported that many users have recently used ChatGPT-related arbitrage bots and invested funds in pursuit of passive income, but after following the scammers' instructions, they found their funds stolen. Users should remain vigilant, carefully check for traps, and protect their assets from harm.

ChainCatcher news, MEV infrastructure developer Semantic Layer announced the completion of a $3 million seed round financing, led by Figment Capital, with participation from Hack VC, Robot Ventures, and Bankless Ventures.Semantic Layer aims to enhance the infrastructure for transaction execution through its Verifiable Aggregation Rules (VAR) and Verifiable Sorting Rules (VSR).Daniel Tong, co-founder of Semantic Layer, stated that the main purpose of this round of financing is to develop the core products of Semantic Layer and increase the market awareness of ASS.

ChainCatcher news, according to official sources, BNB Chain announced improvements to MEV handling through the proposer-builder separation (PBS) model, enhancing network security.It is reported that this model separates block proposers (validators) from block builders, allowing builders to create blocks and propose them to validators, who then choose the most profitable blocks. Currently, over 60% of transactions are incorporated on-chain through builders, and BNB Chain aims to increase this percentage to over 90%.

ChainCatcher message, Arkham disclosed on social media that a certain MEV bot just borrowed $12 million in a flash loan but only made less than $20 in profit.It is reported that the MEV bot was caught in the middle of a user trying to swap $5,000 worth of SHFL for WETH, with a slippage of about 2%.

ChainCatcher news, Sun Yuchen stated on social media that recently, the Tron network received community feedback regarding front-running trades. After investigation, it was found that the Tron network does not have an MEV (Maximal Extractable Value) mechanism. Overall, Tron is significantly ahead of Ethereum and Solana in preventing bot front-running, with an interception rate of around 98%.Tron’s SR (Super Representative) nodes have not implemented any MEV mechanism, and no one can prioritize their transactions on-chain through price manipulation or manipulate blocks by rearranging, inserting, or deleting transactions to gain extra profits.Investigations show that Tron super nodes have not accepted bribes to facilitate front-running trades, and the official stance strictly prohibits any form of assistance for front-running.The so-called MEV trades identified by the community involve a large number of failed scenarios, where bots are using probabilistic methods to exploit victims.Front-running is a strategy employed by bots on every blockchain, and Tron is no exception. However, Tron’s design eliminates privileged mechanisms, such as prioritizing on-chain transaction senders. Additionally, the decentralized voting system supervises SR behavior, significantly reducing the likelihood of front-running and making the market fairer.

ChainCatcher news, according to monitoring by Lookonchain, a whale investor skilled in arbitrage has repeatedly sold at the low points of ETH prices over the past month. This investor sold a total of 19,667 ETH in the past month, worth approximately 47.3 million dollars. The whale obtained ETH through MEV bot arbitrage, but performed poorly in timing the sales, almost always selling at market lows.

ChainCatcher news, according to Cointelegraph, the decentralized exchange aggregator ParaSwap is launching an intent-based trading protocol aimed at mitigating the issue of MEV attacks, which result in millions of dollars in losses from crypto trading every day. The protocol allows users to define their trading "intent" instead of exposing the raw transaction to the mempool, aiming to address this issue by submitting the expected trade in three steps.Reportedly, the process begins with preprocessing, where the user's intent (such as price range) is defined, and then this intent is submitted to an auction, where AI agents compete to propose the most effective execution strategies while considering factors such as liquidity and timing. The winning agent executes the trade through the Portikus Swap module, adhering to the user's intent and minimizing the risk of MEV development.

ChainCatcher news, TRON founder Justin Sun, a member of the Huobi HTX Global Advisory Committee, posted on platform X stating, "TRON itself can prevent MEV attacks, allowing all investors to trade freely on SunPump without worrying about potential MEV attacks. TRON is a blockchain that naturally prevents MEV."

ChainCatcher news, Uniswap founder Hayden Adams posted on the X platform stating: "For Uniswap users, the simplest and most effective way to reduce MEV losses is to allow MetaMask to let us handle transaction submissions, rather than forcing all signed transactions to go through their RPC + OFA submission. We have made multiple requests to MetaMask, but they have still refused, even though this would harm the interests of users and the industry."
