US-Based Bitcoin ETFs Post Roughly $1B Inflows In Past Week: Report

US-based spot Bitcoin ETFs recorded significant inflows of approximately $1 billion over the past week, driven by improved market sentiment amid easing geopolitical tensions in the Middle East. On April 17 alone, net inflows reached $663.9 million, marking the fourth consecutive day of positive movement. BlackRock’s IBIT led with $283 million, followed by Fidelity’s FBTC with $163.42 million and Ark 21Shares’ ARKB with $117.9 million. This brings the two-week total net inflows to over $1.78 billion. Despite the increased institutional interest, Bitcoin’s price declined over 2% in 24 hours, trading around $75,664, while ETF holders remain at a loss with an average cost basis of $82,247.

a16z Founder: In the Agent Era, What Truly Matters Has Changed

Marc Andreessen, co-founder of a16z, argues that the current AI boom is not an overnight success but the culmination of 80 years of research, now delivering practical results. He emphasizes that this era is defined by the convergence of four key capabilities: large language models (LLMs), reasoning, coding, and agents capable of recursive self-improvement. Andreessen describes the agent architecture—combining an LLM with a shell, file system, markdown, and cron/loop—as a fundamental shift beyond chatbots. This structure leverages existing software components, allowing agents to maintain state, introspect, and extend their own functionality. He predicts a move away from traditional GUI and browser-based interactions toward an "agent-first" world where software is primarily operated by bots, not humans, with people simply stating their goals. He draws parallels to the 2000 internet bubble but notes key differences: current AI infrastructure investments are led by cash-rich giants and quickly monetized. He highlights that scaling constraints involve not just GPUs but the entire chip ecosystem. Open source and edge inference are crucial for democratizing knowledge and enabling low-latency, cost-effective applications on local hardware. Finally, Andreessen identifies significant non-technical challenges: potential short-term cybersecurity crises, the need for "proof of human" identity solutions, financial infrastructure for agents, and institutional resistance from sectors like education and healthcare. He cautions that societal adoption will be slower than technological change.

The Code Was Fine, But It Was Still Hacked: What Is the 'DVN Configuration Vulnerability' Behind the Biggest Hack of 2026?

Title: Code Was Secure, Yet $293M Stolen: The 2026 DVN Configuration Breach Explained On April 18, 2026, Kelp DAO’s restaking protocol was exploited, losing 116,500 rsETH (worth $293M at the time) due to a configuration flaw—not a smart contract vulnerability. The attacker used a forged cross-chain message to drain funds via LayerZero’s bridge, then dispersed the stolen rsETH across Aave V3, Compound V3, and Euler to borrow real assets, ultimately escaping with $236M in WETH. The root cause was a critical misconfiguration in Kelp’s LayerZero V2 setup: the protocol used a 1-of-1 Decentralized Verifier Network (DVN) threshold, meaning only one node approval was needed to validate cross-chain messages. The attacker compromised that single node, allowing unauthorized minting of rsETH on Ethereum. This configuration choice—permitted by LayerZero but highly risky—left zero fault tolerance. In contrast, protocols like ApeChain using multi-node validation (e.g., 2-of-3 or 5-of-9) remained secure. This incident highlights a blind spot in DeFi security audits: tools like Slither and Mythril scan code for logic flaws but ignore configuration parameters. The 2022 Nomad hack ($190M loss) also stemmed from a config error, bringing total losses from such issues to ~$482M—rivaling private key breaches. The Kelp exploit underscores the need for standardized config audits and higher baseline security in cross-chain designs.

The More Frequently They Are Updated, the More Similar Claude Code and Codex Become

OpenAI's recent release of GPT-5.4-Cyber demonstrates a striking convergence with Anthropic's Claude Mythos, reflecting a broader trend of product and strategic alignment between the two AI giants. This is particularly evident in their flagship coding assistants, Codex and Claude Code, which have evolved from distinct philosophies into increasingly similar tools. Initially, Codex emphasized speed and real-time interaction, acting like a fast, junior developer, while Claude Code focused on handling extreme complexity with methodical, large-context analysis. However, both have adopted near-identical solutions to core challenges, such as using isolated sub-tasks or agent teams to prevent context pollution during large-scale code modifications. Benchmark results show a tight race: Codex leads in terminal tasks, while Claude Code excels in complex software engineering benchmarks. Community feedback highlights nuanced differences; Claude Code is faster but can accumulate technical debt, whereas Codex is slower but more deliberate and autonomous. The open-source framework OpenClaw has accelerated this homogenization by standardizing workflows, eroding proprietary advantages. Ultimately, the competition has shifted from pure capability to ecosystem strategy, pricing, and user experience. As these tools become ubiquitous, the developer's role evolves toward higher-level problem definition and architectural thinking, beyond automated code generation.

Kelp DAO Suffers $292 Million rsETH Exploit – Details

Kelp DAO has suffered a major cross-chain exploit resulting in the loss of approximately 116,500 rsETH, valued at nearly $292 million. The attack targeted a vulnerability in the protocol's cross-chain bridge mechanism, specifically through LayerZero’s EndpointV2. On-chain investigator ZachXBT first identified the breach, noting that the attacker used Tornado Cash to conceal funding sources. In response, Kelp DAO immediately paused all rsETH contracts across mainnet and Layer-2 networks, preventing two additional attempts to drain another $100 million in assets. The protocol is collaborating with LayerZero and Unichain for a full investigation. The incident has impacted the broader DeFi ecosystem, leading Aave to freeze rsETH markets on its V3 and V4 deployments as a precaution, though its own contracts remain secure. The stolen rsETH represents around 18% of its circulating supply, significantly damaging liquidity and user confidence.
