Ethereum (ETH) founder Vitalik Buterin outlined a four-year roadmap for the network at the Hong Kong Web3 Festival, highlighting enhanced scalability and quantum security as key goals, PA News reported. Short-term tasks include raising the gas limit to improve scalability, extending the EVM with Zero-Knowledge proofs (CKEVM), and supporting smart contract wallets and quantum-resistant signatures via account abstraction. Buterin added that by 2028, the plan is to reduce transaction finality time to between 10 and 20 seconds and introduce zkVM technology, which would allow even low-spec devices to verify the chain directly. He stressed that Ethereum's fundamental goal is to be the world's most secure and decentralized blockchain, rather than competing on speed with high-frequency trading platforms.

On-chain analyst ZachXBT, who previously alleged price manipulation in RaveDAO (RAVE), has now turned his criticism to Memecore (M). On X, he challenged the project to provide data justifying its position as a top-20 cryptocurrency with a $6 billion market capitalization and to explain why insiders hold over 90% of the M supply. The analyst has recently posted a series of warnings about tokens that have surged in price, such as RAVE, alleging that their teams hold the majority of the supply to manipulate prices. He had previously flagged suspicious price movements in other tokens, including SIREN, MYX, COAI, PIPPIN, and RIVER. Following ZachXBT's comments, M fell from the $3.4 level and is currently trading at $3.18, down 8.29% from yesterday.

Binance CEO Richard Teng announced on X that weekend trading volume for the exchange's perpetual futures linked to traditional assets surged by approximately 300% between January and March.

The two leading global stablecoin issuers, Circle and Tether, are moving to secure trademarks in South Korea in a bid to preemptively capture the market, Electronic Times Internet reported. According to data from the Korea Intellectual Property Rights Information Service (KIPRIS) on April 20, Circle has filed for a total of 11 trademarks in the country. These filings have been concentrated in the last two years, with three this year and eight last year. Tether has also filed for a total of six trademarks, with two this year and two last year.

LayerZero (ZRO) announced on its official X account that it believes the North Korean hacking group Lazarus is behind the recent exploit of Kelp DAO's rsETH. LayerZero was the cross-chain bridge utilized by the hackers in the incident yesterday. According to the company, the attackers used a sophisticated method to compromise the underlying RPC infrastructure of LayerZero Labs' Decentralized Verification Network (DVN). They hacked two independent RPC nodes, replaced them with malicious binaries, and launched a distributed denial-of-service (DDoS) attack on normal nodes to redirect the system to the compromised ones. The estimated damages are $290 million. LayerZero stated that it had previously recommended Kelp DAO use a multi-DVN setup with multiple validators, but Kelp DAO's decision to maintain a single-validator structure left its defense system vulnerable. The incident was described as a security configuration issue with a specific application, not a flaw in the protocol itself, and no other assets or applications were affected. LayerZero has since replaced the compromised RPC nodes, restored normal service, and is working with authorities worldwide to track the stolen funds.

Crypto industry losses from hacks have surpassed $600 million so far in April, marking the highest monthly total since February 2025, BeInCrypto reported. According to data from DeFiLlama, this month's losses are roughly 3.7 times the $165 million lost during the entire first quarter. Hacks on KelpDAO (around $290 million) and Drift (around $285 million) accounted for about 95% of the total.

The DeFi fund outflow that began after the KelpDAO rsETH bridge hack has now spread to the Solana ecosystem, Wu Blockchain reported. The report noted a surge in both deposit APY and utilization rates across the USDC pools of Kamino (KMNO), a Solana-based automated liquidity management protocol. Notably, the Prime Market USDC pool, valued at approximately $178 million, has reached 100% utilization, completely depleting its available liquidity. Utilization rates for other major vaults, including the Stakehouse USDC vault and the LockawayX RWA USDC vault, have also surpassed 95%.

Asian Web3 research and consulting firm Tiger Research has highlighted that recurring hacks and a fund recovery rate of under 10% are eroding trust in the industry. According to its report, social engineering accounted for 74.7% of hacks in the first quarter of this year, making human error the primary attack vector over code vulnerabilities. The report explained that the on-chain nature of these thefts makes them difficult to reverse, often resulting in permanent losses. While centralized exchanges can absorb such damages through reserves and coordinated efforts, DeFi's response capabilities are limited. Tiger Research emphasized that attracting institutional investment requires prioritizing the development of robust incident response structures and responsible operating systems over purely technological solutions.

An address labeled as a strategic partner of LayerZero (ZRO) deposited 855,000 ZRO, worth approximately $1.42 million, to Binance about 30 minutes ago, according to EmberCN. The deposit was part of a larger transfer totaling 1.21 million ZRO ($1.97 million) that was sent to 52 different addresses. EmberCN noted that LayerZero was the cross-chain bridge used by a hacker in yesterday's rsETH exploit, and the price of ZRO has fallen 18% since the incident.

An over-the-counter (OTC) whale address starting with 0xd4584, previously known for buying hundreds of millions of dollars in ETH and cbBTC, has withdrawn 98,032 wstETH ($272 million) and 3,000 cbBTC ($221.6 million) from the crypto lending platform Aave, Lookonchain reported. The on-chain tracker noted that the whale appeared to have difficulty withdrawing ETH from Aave following the hack of KelpDAO's rsETH bridge. The whale also lost 237 ETH ($540,000) while swapping some of the bridged ETH. The address still holds about 10,000 ETH ($22.8 million) on Aave. The KelpDAO exploit over the weekend resulted in the theft of over $290 million in assets, and it was previously reported that more than $10 billion in funds had been withdrawn from Aave amid the fallout.

Prediction market platform Polymarket is seeking to raise an additional $400 million at a target valuation of $15 billion, The Information reported. The company's valuation is believed to have surged several-fold in recent months amid a spike in demand for predictions related to real-world assets (RWA) and political events.

DeFi lending platform Fluid (FLUID) has launched an aWETH repayment feature designed to assist Ethereum (ETH) borrowers with liquidity and risk management, the project announced on X. According to Fluid, the feature allows ETH borrowers to convert their collateral into wstETH or weETH, thereby securing immediate liquidity and reducing their risk of liquidation. The platform added that even when borrowers have other outstanding debts, only the ETH collateral is converted, while the original debt structure remains unchanged.

DeFiLlama founder 0xngmi said on X that Kelp DAO has three potential post-hack measures to consider after suffering a $292 million (116,500 rsETH) exploit over the weekend. The options are: - Distributing the loss across all users, resulting in an 18.5% asset reduction for everyone. - Concentrating the loss on rsETH holders by reducing the value of rsETH on Layer 2 networks to zero. - Rolling back assets using a previous snapshot and compensating only for the stolen funds, a measure considered difficult to implement due to subsequent asset movements. All three scenarios are expected to create risks for Aave, potentially forcing it to sell AAVE tokens or incur bad debt. Aave has currently frozen rsETH across its V3 and V4 protocols and has also frozen its WETH reserves. Aave founder Stani Kulechov stated that the incident was a hack of an external bridge, not Aave itself, and that the team is working to minimize further damage.

China has held its de facto benchmark interest rates steady for the 11th consecutive month. The People's Bank of China (PBoC) announced it is maintaining the one-year Loan Prime Rate (LPR), the benchmark for general loans, at 3.0%. The five-year LPR, which serves as the reference for mortgages, will remain at 3.5%. The PBoC has kept the rates frozen for 11 months since lowering both the one-year and five-year LPRs by 10 basis points in May of last year.

Although South Korea's ruling and opposition parties have agreed to convene the National Policy Committee's first subcommittee on bills later this month, discussions on the country's Phase 2 virtual asset legislation are unlikely to proceed, Chosun Biz reported. The Democratic Party had initially planned to finalize the government's draft of the bill, tentatively known as the Digital Asset Basic Act, during a party-government consultation last month. However, that meeting was indefinitely postponed as the government shifted its focus to responding to the U.S.-Iran war.

More than $10 billion has been withdrawn from the Aave protocol following an exploit targeting rsETH over the weekend, EmberCN reported. A total of $10.1 billion in assets left the protocol, with $4.5 billion of that amount in stablecoins. The outflow has pushed the annual percentage yield (APY) for stablecoin deposits on Aave to around 13.4%, while the protocol's total value locked has fallen from $45.8 billion to $35.7 billion. Previously, Ethereum restaking protocol Kelp DAO announced it had suspended rsETH contracts on its mainnet and multiple Layer 2 networks after detecting suspicious cross-chain activity over the weekend. The total losses from the exploit are estimated to be over $292 million.

CoinMarketCap's Altcoin Season Index currently stands at 38. The index measures whether it is an "altcoin season" or a "Bitcoin season" by comparing the price performance of the top 100 coins by market capitalization (excluding stablecoins and wrapped coins) against Bitcoin. An altcoin season is declared if 75% of the top 100 altcoins have outperformed Bitcoin over the past 90 days. A score closer to 100 indicates a stronger altcoin season.

A multisig address associated with the RaveDAO (RAVE) team deposited an additional 23 million RAVE, worth $23 million, into Bitget three hours ago, triggering a further 40% price drop, on-chain analyst ZachXBT reported on X. The token had already plummeted from $26 to $1 over the weekend. ZachXBT said he had requested investigations from Binance, Bitget, and Gate yesterday into alleged price manipulation of RAVE. Previous analyses suggested the team, which holds a majority of the supply, had orchestrated a short squeeze to artificially inflate the price. At its peak, RAVE traded above $26, placing it among the top 15 cryptocurrencies by market capitalization, but it collapsed by more than 95% within hours after exchanges launched their inquiries. ZachXBT added that suspicious price movements have also been observed in other tokens, including SIREN, MYX, COAI, M, PIPPIN, and RIVER.
