Base MCP is built on the OAuth 2.1 standard for authentication, generating wallet request links through the storage request feature, and the MCP server does not hold or access user private keys.

On-chain analyst "b-block" posted on social media on Monday that a counterfeit Uniswap website is stealing funds from multiple wallets, with assets held by the scammers valued at over $400,000. Stacy Muur, founder of the Web3 marketing agency Green Dots, shared screenshots of false sponsored results from search engines, criticizing Google for ignoring this issue for years, leading to fake links ranking above real ones, resulting in users continuously being scammed.According to Etherscan data, the two flagged addresses hold a total of about 146 ETH, valued at approximately $306,000. DeFiLlama pointed out that fake ads on Google are a common source of phishing attacks. The crypto nonprofit organization Security Alliance (SEAL) reported in April that phishing activities on Google searches significantly increased in March, with attackers deploying highly deceptive fake ads by paying for or hijacking legitimate ad accounts, using seemingly real URLs to bypass Google's automatic checks, and loading malicious payloads through hidden iframes.SEAL has blocked over 356 malicious ad links and stated that the volume of Google ads deployed by attackers has remained stable for over a year, with no slowdown in attack activities. Reports indicate that between March 13 and 30 alone, a total of $1.27 million was stolen. Additionally, earlier this month, there were malicious ad campaigns targeting Mac users that utilized Google ads and the AI chatbot Claude for shared chats. Malwarebytes also reported that Facebook is similarly a hotspot for fake ads and scams.

According to Blockaid monitoring, the cross-chain routing protocol Squid is currently under continuous attack on the SquidRouterModule on the Ethereum and Base networks. Within about two hours of the attack, 86 Gnosis Safe wallets have been emptied, with losses amounting to approximately 3 million dollars.The attacker subsequently exchanged all stolen tokens for DAI through their controlled Uniswap V3 liquidity pool and consolidated them into a single address. Currently, this consolidated wallet holds approximately 3.07 million dollars in DAI.

Uniswap's governance proposal aims to extend the protocol fee collection and burning infrastructure to BNB Chain and Polygon, and to complete the fee activation process on Celo that was not executed due to a configuration error.The proposal includes: setting the fee receiving address for the V2 protocol on BNB Chain, Polygon, and Celo to TokenJar, and designating the V3 Factory owner on the relevant chains as V3OpenFeeAdapter; additionally, Celo will transfer the feeToSetter role and V4 PoolManager ownership to CrossChainAccount.The proposal states that fees from each chain will be aggregated into the corresponding TokenJar, and then UNI will be bridged back to the Ethereum mainnet and sent to the burn address.

According to GMGN monitoring, the market value of the Ethereum ecosystem token uPEG (Unipeg) has rebounded above 10 million USD, currently reported at 10.5 million USD, with a 24-hour increase of 36%, and a trading volume of 2.3 million USD during the same period.It is reported that Unipeg is an experimental on-chain object based on Uniswap v4 Hooks, which generates a unique unicorn image in real-time after each swap in the liquidity pool.

Grayscale has completed the rebalancing of its cryptocurrency industry fund. The DeFi fund has added the Ethena token ENA, with a weight of 13.59%, making it the fourth largest holding in the fund. At the same time, the fund has completely removed the Aerodrome Finance token AERO.After the adjustment, the main holdings of the fund include: Uniswap (UNI) at 35.22%, Aave (AAVE) at 21.36%, Ondo Finance (ONDO) at 19.83%, Curve DAO (CRV) at 5.27%, and Lido DAO (LDO) at 4.73%. Additionally, the smart contract platform fund did not increase or decrease its assets this quarter. The holding weight of Ethereum (ETH) has risen to 30.14%, surpassing Solana (SOL) at 29.69% to become the largest holding. Cardano (ADA) ranks third with a weight of 17.96%, followed by Avalanche, Hedera, and Sui.This adjustment is primarily based on the methodology of the CoinDesk DeFi Selected Index and the CoinDesk Smart Contract Platform Selected Cap Index, aiming to ensure that the fund's holdings are consistent with liquidity, custody, and market capitalization requirements.

According to DL News, Uniswap DAO is voting on a proposal to reclaim approximately 12.5 million UNI (about $42 million) that was previously lent to representatives and the foundation. The voting will end on May 8, with about 53% in support, 46% abstaining, and very few opposing votes.Between 2022 and 2023, the DAO lent out the aforementioned governance tokens to enhance governance participation. Uniswap Labs stated that current governance activity has significantly increased, with an average voting participation of about 750,000 votes, and the related mechanism has achieved the expected results. This reclamation also aims to address the issue of incentive misalignment—some representatives hold significant voting power without having their own economic exposure. At the same time, this move is seen as a response to external doubts about the degree of decentralization in governance.In addition, the Uniswap ecosystem has recently promoted reforms including fee mechanisms, token buyback and burn, and governance structure optimization to further enhance governance transparency and decentralization.

According to GMGN data, the market capitalization of the ETH chain ecosystem token sato briefly surpassed 9 million USD, currently reported at approximately 9.4 million USD, with a daily increase of over 700%. The total supply of this token is 21 million pieces, minted and burned through the Uniswap v4 curve mechanism. Buying will generate new tokens and lock ETH as reserves, while selling will exchange ETH from the reserves and burn tokens. The current cumulative buying scale has approached 1000 ETH.ChainCatcher reminds users that the prices of Meme coins are highly volatile, and investors should be aware of the risks.

According to GMGN market information, the market capitalization of the Ethereum ecosystem token uPEG briefly surpassed $12 million, setting a new historical high, currently reported at $11.22 million, with a 24-hour increase of 52.7% and a 24-hour trading volume of $3.7 million.Public information shows that Unipeg (token uPEG) focuses on on-chain objects built with Uniswap V4 Hooks.

This move caused uPEG to briefly surge over 3 times.ChainCatcher reminds users that the prices of related tokens are highly volatile, and users should invest cautiously.

The DeFi Education Fund, along with Aave Labs, Uniswap Labs, Paradigm, Andreessen Horowitz, and other organizations, has sent a letter to the U.S. SEC in response to the recent statement released by the trading and markets division regarding the registration of "non-custodial user interface" brokers for crypto asset securities.The signatories support the statement that the "non-custodial user interface," which only provides a technical entry point and allows users to manage their assets independently, should be excluded from broker registration. They also urge the SEC to establish clearer and more sustainable definitions of "broker" through formal rulemaking, to avoid incorrectly categorizing neutral software tool providers, validators, RPC/API, oracles, cloud services, and other infrastructure under broker regulations. This would provide long-term legal certainty for blockchain infrastructure innovation while ensuring investor protection.Previously, the SEC's trading and markets division indicated that some DeFi trading interfaces do not need to register as brokers, allowing for policy space for related applications. Supporters believe that the new regulations could cover infrastructure participants such as validators, APIs, and oracles. Currently, the U.S. crypto market legislation, the CLARITY Act, is stalled in the Senate.

The Uniswap developer platform has officially launched. This platform provides developers with a new documentation website, AI toolkit, API Playground, and technical guides. In addition, the Uniswap API has added liquidity provider (LP) endpoints, allowing developers to create, adjust positions, and withdraw fees directly through the API.The API currently supports 10 million assets across 18 chains, with a routing speed of about 200 milliseconds and a transaction success rate of over 97%. In the future, the platform plans to launch dashboard analytics features to track API integration performance and provide on-chain operation combination paths to support cross-chain token swaps and bridging. Currently, this API is available for free use.

According to DL News, Coinbase has opened access to decentralized exchange (DEX) trading for UK customers, allowing users to access DeFi platforms such as Uniswap and Aerodrome through the Coinbase app to trade Base native assets, with plans to expand to other networks like Solana.The CEO of Coinbase UK stated that the UK is the most important market outside the United States, and this launch aims to demonstrate to the government the safety of DeFi under compliant operations. The design philosophy of this service is to maintain Coinbase's easy experience on the front end while integrating DeFi protocols on the back end. Coinbase will filter asset risks by collaborating with trusted third parties, such as high concentration of holdings potentially indicating rug pull risks. This is part of Coinbase's strategy to build a "full-service exchange," with plans to launch more services in the UK this year.

According to on-chain analyst @ai_9684xtpa, a trader spent 0.2 ETH ($436) on the Ethereum mainnet to buy 77,000 DOT using Uniswap and sold it on a CEX for $10,042.Subsequently, they used the same method to spend a total of 1.1 ETH to buy DOT, attempting various cross-chain methods while buying low and selling high in different liquidity pools. Ultimately, they successfully crossed from the ETH mainnet to the Base network via Hyperbridge, selling 503,000 DOT for 68.72 ETH in one transaction, making a profit of $150,000.

Uniswap founder Hayden Adams tweeted that after the Uniswap API integrated with the MetaMask aggregation trading routing system a month ago, it currently accounts for about 40% of its swap transaction share. He also stated that Uniswap has made the API key available for free to all developers.
