According to BusinessWorld, the Central Bank of the Philippines has warned the public and cryptocurrency users not to trade with unauthorized virtual asset service providers, as this may lead to financial losses due to fraud, security vulnerabilities, and operational failures.The central bank stated that unauthorized VASPs also pose risks such as lack of legal recourse, absence of consumer assistance mechanisms, poor service quality, false advertising, improper handling of private keys, cybersecurity incidents, and data privacy issues. Additionally, access may be restricted due to government enforcement actions against illegal operations. The Central Bank of the Philippines has committed to continuing cooperation with the Securities and Exchange Commission, the National Telecommunications Commission, and other departments to restrict access for Philippine users to unauthorized VASP platforms, and urges consumers to protect personal information, maintain cybersecurity hygiene, and only trade with licensed institutions.

Bitget, through the Blockchain4Her program, continues to promote the popularization of Web3 women's education and community building in emerging markets such as the Philippines. This program focuses on providing a systematic blockchain knowledge framework for women and youth, helping them participate in the long-term development of Web3 with a solid understanding and gain more substantial opportunities within the industry.To achieve this goal, Blockchain4Her has supported several grassroots initiatives led by local female advocates. These include: transforming blockchain technology into practical development opportunities for underdeveloped communities; developing exclusive learning materials titled "Young Learners' Encyclopedia" for youth; and building a learning community focused on risk control and trading discipline. These initiatives not only help local beginners avoid misinformation and establish a rational understanding of Web3 but also align closely with Bitget's partnership with UNICEF in promoting digital skills and blockchain education globally.Bitget CEO and Blockchain4Her founder Gracy Chen stated, "Our original intention is to provide a more equal and open environment for women to explore Web3. Seeing more and more outstanding women engaging in community building shows us how true industry inclusivity takes root and flourishes from the grassroots."

According to Cointelegraph, the decentralized finance platform Flying Tulip, founded by Andre Cronje, has launched a withdrawal circuit breaker mechanism that can delay or queue withdrawals during abnormal capital outflows to limit potential losses and buy time for the team to investigate.The operation of this mechanism varies across different products: in the Perpetual PUT product, withdrawals may be rolled back, and users will need to try again later; in ftUSD, withdrawals will enter a queue and can be claimed after a delay. Flying Tulip stated that this mechanism employs a "fail-open" design, meaning that transactions can continue to be executed even if the safety mechanism fails.

According to RHEA Finance's official disclosure, the NEAR ecosystem lending protocol RHEA Finance (formerly known as Burrow Finance) experienced a margin trading feature hack, resulting in a loss of approximately $18.4 million.The attacker began laying the groundwork several days prior by creating multiple fake token pools on Ref Finance and injecting liquidity, constructing a malicious exchange route that exploited a vulnerability in the protocol's slippage protection mechanism—this mechanism did not account for the scenario where intermediate tokens were reused when calculating the minimum output of multi-step exchanges—leading to the borrowed debt tokens being directed into fake token pools controlled by the attacker, triggering a large-scale forced liquidation that ultimately drained the protocol's reserve pool. During the attack, the attacker deleted a total of 55 intermediate accounts to cover their tracks. Currently, the attacker has returned approximately 3.359 million USDC and 1.564 million NEAR to the RHEA lending contract, while another 4.34 million USDT has been frozen (of which Tether froze 3.291 million and NEAR Intents froze 1.053 million). The protocol contract has been suspended, and the team is collaborating with centralized exchanges for joint tracking and has notified relevant law enforcement agencies.

According to CoinDesk, blockchain analytics firm Elliptic stated that the Drift Protocol attack resulted in a loss of $285 million, with "multiple signs" pointing to the North Korean-supported DPRK hacker organization. Elliptic focused on analyzing on-chain behavior, money laundering techniques, and signals at the network level, all of which align with previous state-affiliated attacks.The Elliptic report noted: "If confirmed, this would be the 18th DPRK attack tracked by Elliptic this year, with over $300 million stolen to date." On a technical level, Elliptic described this attack as "premeditated and meticulously planned," with early test transactions and pre-positioned wallets prior to the main attack. After the execution of the attack, the funds were quickly consolidated and transferred across chains, converted into more liquid assets, forming an organized and repeatable money laundering process aimed at obscuring the source of funds while maintaining control.This incident involved over ten types of assets, with funds being transferred across chains from Solana to Ethereum and other chains, further highlighting the importance of cross-chain tracing capabilities. Drift Protocol is the largest decentralized perpetual contract trading platform on the Solana blockchain, and its token has dropped over 40% to approximately $0.06 since the hack.

Aave released an analysis of the Swap event: a user executed a token exchange operation through the CoW Swap router integrated into the Aave interface. The user attempted to exchange 50,432,688 aEthUSDT (worth approximately $5,043,270) for aEthAAVE. Due to the user's order being exceptionally large in a market with insufficient liquidity, the quotes from CoW Swap were extremely poor, and the user confirmed acceptance of the quote.It should be noted that the Aave protocol itself was never at risk, as this exchange occurred outside the protocol, through the aforementioned third-party Swap protocol. Currently, the relevant user has not contacted the Aave team. The key issue in this event was insufficient market liquidity, rather than slippage.Insufficient liquidity refers to the inability of the market to provide enough assets at a specific price to meet large orders, resulting in severe price deviations. The user's order was far larger than the available market liquidity, and the CoW Swap quote was 99.9% lower than the expected market clearing price; the adverse outcome stemmed from the user's confirmation of the quote, rather than price changes during execution.The root cause of this event was the routing of large trades in a market with insufficient liquidity, leading to extreme price shocks. The user executed the trade after confirming a clear warning on the interface. To prevent similar events, Aave Shield will be introduced in the Swap widget: it will default to blocking exchanges with price shocks exceeding 25%, and users will need to manually disable this feature to execute high-risk trades. The transaction incurred approximately $110,368 in fees, which will be refunded after user verification.

The on-chain analysis platform Lookonchain stated in a social media post that the party responsible for a $50 million loss due to slippage may be Garrett Jin, the operator of the "1011 insider address."On-chain tracking shows that 13 wallet addresses associated with him withdrew USDC or USDT from Binance on February 16 and February 20, and have recently become active again, transferring funds to two new wallets. One of the wallets shares the same Binance deposit address as Garrett Jin.Lookonchain noted that Garrett Jin previously sold 261,024 ETH (approximately $543 million) and 11,318 BTC (approximately $761 million) on February 15 and February 20, respectively, and the withdrawal times from Binance for the aforementioned wallets are close to these transactions.

On-chain data analyst Yu Jin stated that earlier today, the "whale/institution that bought AAVE and suffered a slippage loss of over 50 million USD" still holds 302 million USDC in another wallet.

Binance founder CZ commented on "a user buying AAVE and suffering a slippage loss of over 50 million dollars" by saying: "It's very unfortunate; liquidity is the best user protection."

A crypto user lost approximately $50 million in a token swap transaction on Thursday. On-chain data shows that the user exchanged about $50.43 million worth of aEthUSDT for aEthAAVE through the CoW Protocol, but due to insufficient liquidity pool depth, the transaction experienced a slippage of over 99%, ultimately resulting in the user receiving only about 327 aEthAAVE, worth approximately $36,000, with the difference being captured by arbitrage traders and network intermediaries.Aave founder Stani Kulechov posted on the X platform that the user purchased AAVE using $50 million USDT through the Aave interface. Due to the unusually large size of the single order, the interface issued an extreme slippage warning to the user and required confirmation. After accepting the warning on a mobile device, the user proceeded with the transaction.Kulechov stated that the CoW Swap router operated as expected and followed industry-standard operating procedures, but the outcome was clearly not ideal. Kulechov mentioned that Aave plans to contact the user and refund approximately $600,000 in fees charged from the transaction. Days before this incident, about $27 million in positions on Aave were liquidated, and some market participants believe that this liquidation may be related to a temporary pricing issue with wstETH.
