Resumo

El exploit de seguridad en la cadena SagaEVM, ocurrido el 21 de enero, resultó en el robo de aproximadamente 7 millones de dólares en activos, que fueron transferidos en parte a Ethereum. El equipo de Saga detuvo la cadena para evitar más transferencias no autorizadas e identificó la billetera del atacante, colaborando con exchanges para bloquearla y recuperar los fondos.

Después de que se identificó la explotación, el primer día, el equipo pausó la cadena en la altura de bloque 6,593,800 para detener las transferencias no autorizadas. Además, parece haber involucrado una secuencia de implementaciones de contratos, interacciones cross-chain y retiros rápidos de liquidez que permitieron al atacante extraer activos.

Los activos robados, incluido USDC, fueron transferidos a la red principal de Ethereum y, en algunos casos, convertidos a ETH u otros tokens. Asimismo, Saga ha identificado la billetera vinculada a la explotación y está trabajando con exchanges y operadores de puentes para incluirla en la lista negra y apoyar la recuperación de activos.

Con ello, actualmente, el equipo de Saga está realizando una investigación forense detallada y planea publicar un informe técnico post-mortem exhaustivo.

La explotación afectó a la propia cadena de red SagaEVM, así como a entornos como Colt y Mustang que dependen de la funcionalidad EVM, mientras que la red principal de Saga SSC, la capa de consenso y la seguridad del Validador no se vieron afectadas, y no hubo evidencia de compromiso de claves privadas.

Singapore Bets on AI Advantages as Hong Kong Lures Fund Managers with Tax Cuts

Singapore is leveraging its access to cutting-edge AI technology from both the US and China, including models from firms like Moonshot and DeepSeek, to attract and retain investment managers. This strategy positions the city-state as a neutral hub amidst US-China tech competition. In contrast, Hong Kong's primary draw is a proposed tax exemption scheme for fund managers, family offices, and private equity specialists, though proprietary trading firms like Jane Street are currently excluded. While Hong Kong's tax incentives could lower costs, industry experts note that Singapore's superior access to advanced AI tools is a critical long-term advantage, especially for quantitative funds reliant on complex algorithms. This technological gap is reportedly prompting some Hong Kong-based quant funds to consider moving key research operations to Singapore. The competition highlights how financial centers are increasingly competing through both fiscal policy and technology access, with firms weighing lower taxes against superior tech infrastructure.

The spot Ethereum ETF sector also saw a net outflow of $2.26 million for the week, led by BlackRock's ETHA. In contrast, several altcoin-based ETFs attracted new capital. SOL-ETFs led with an inflow of $10.26 million, followed by funds tied to HYPE, XRP, LINK, and HBAR. DOGE-ETFs were an exception with a minor outflow. Activity in the Hong Kong market remained minimal. This follows a week where over $1 billion flowed into various crypto funds.

Crypto Adoption in the EU Stalls: ECB Finds Only 0.2% of Online Payments Use It

The European Central Bank (ECB)'s latest survey on cash use by eurozone companies reveals a very low adoption rate for cryptocurrencies in the region. The survey of 8,205 firms found cash remains the most widely accepted payment method at physical points of sale (92%), followed by cards (88%). Mobile payments grew significantly from 36% in 2024 to 68% in 2026. However, digital assets have minimal penetration: only 0.2% of businesses accept crypto or stablecoins for online purchases, rising to just 1% at physical stores. This is far below adoption levels in emerging markets. The ECB emphasized the need to prevent growing payment automation from undermining cash's viability. Despite acknowledging crypto's potential benefits like reduced intermediaries and fees, financial institutions have been slow to implement systems. Consequently, European payment operators have yet to capitalize on the regulatory clarity provided by the full implementation of the Markets in Crypto-Assets (MiCA) framework. An Elliptic policy head noted MiCA now allows operators to confidently develop compliant crypto payment solutions for the European market.

Media: Anthropic Aims for Revenue Up to $200 Billion by 2028 Ahead of IPO

Anthropic, the AI company behind Claude, is reportedly projecting its revenue could reach between $190 billion and $200 billion by 2028, according to sources cited by Reuters. This forecast, significantly higher than its reported $47 billion annual run-rate in May 2026, is being used by investors and bankers to value the company ahead of a potential IPO. Anthropic has confidentially filed with the SEC, with listing details dependent on market conditions and regulatory approval. The valuation reportedly applies a revenue multiple (EV/Revenue) to these future 2028 figures, an approach common for high-growth tech firms but unusual for a forecast two years ahead of an IPO. This reflects confidence in Anthropic's rapid scaling; its annual run-rate grew tenfold yearly for three years leading into 2026, jumping from ~$9B in late 2025 to over $47B by May 2026. Investors are betting the company's massive spending on GPUs, model training, and infrastructure will eventually outpace costs, leading to expanding margins. Public companies like Palantir, Cloudflare, and SpaceX, valued at high multiples of their forward revenue, serve as benchmarks. While this forward-looking method has precedents, some analysts question the sustainability of such valuations and the actual productivity gains from AI. Despite these concerns, earlier reports suggested Anthropic could be valued at over $1 trillion for its IPO.

Open Blockchain Business: Who Gets the Fees and Why a Foundation is Needed

Business of Open Blockchain: Who Gets the Fees and Why a Foundation is Needed In public blockchains, user transaction fees do not simply become "revenue" for a single entity. The flow of money is complex and protocol-dependent. In Ethereum, fees consist of a base fee (burned, permanently removing ETH from circulation) and a priority tip (paid to the validator). In Solana, half the base fee is burned and half goes to the validator, while priority fees go entirely to validators. Thus, "fees" are not synonymous with "project revenue"; they may go to network operators or be destroyed. Foundations like the Ethereum Foundation do not take a cut of user fees. They are funded by their own treasuries, which can generate income (e.g., from staking rewards) and finance ecosystem development, research, and security. Their role is to fund public goods that are hard to monetize directly. Developers of open-source blockchain code can monetize through services, not the code itself. For example, Optimism provides its technology freely but sells enterprise support and managed services (OP Enterprise). Additionally, networks built on Optimism's tech, like Coinbase's Base, share a portion of their revenue with the Optimism ecosystem via agreements, creating an economic link. Token holders do not automatically receive fees as dividends. In Optimism, a portion of protocol revenue is now used to buy back and treasury-lock OP tokens, creating an indirect link between network usage and token economics. In Ethereum, fee burning reduces ETH supply but doesn't distribute funds to all holders; stakers and validators receive direct rewards. For evaluation, analysts should look beyond total fee figures. Key questions are: Who paid and for what? Where did the money go (to validators, operators, treasury, or burning)? What were the recipient's costs? Is there a mechanism linking this income to the token? The same fee amount impacts different blockchain economies in vastly different ways depending on these factors.
