Resumen

A U.S. federal judge dismissed a class-action lawsuit against Uniswap Labs and its founder, Hayden Adams, which sought to hold the decentralized exchange accountable for alleged rug pulls and pump-and-dump schemes on its platform. Judge Katherine Polk Failla ruled that Uniswap cannot be held responsible for the fraudulent actions of anonymous token issuers, emphasizing that operating a decentralized, open-source trading platform does not constitute assisting fraud. The plaintiffs had refiled the case with state-level consumer protection claims after an earlier dismissal, but the court reaffirmed legal protections for DeFi infrastructure. Following the decision, Uniswap's native token UNI saw a price increase and higher trading volume. The ruling is seen as a significant legal victory for the DeFi sector.

Uniswap Labs and its founder, Hayden Adams, saw a significant legal victory when a US federal judge dismissed a four-year-old class-action complaint seeking to hold the decentralized exchange accountable for rug pull and pump-and-dump fraud on its platform.

The decision was delivered by Judge Katherine Polk Failla in Manhattan on March 2, ruling that Uniswap cannot be held responsible for the actions of anonymous token issuers and that operating as a decentralized platform providing an open‐source trading environment does not constitute assisting fraud.

Federal Court Backs DeFi Infrastructure

Nessa Risley led the plaintiffs and filed the first lawsuit against Hayden Adams and Uniswap in April 2022. The lawsuit was dismissed in August 2023 and upheld on appeal. Again, the plaintiffs refiled in May; this time, they switched to state consumer protection concerns and claimed that the platform permitted pump-and-dump schemes and rug pulls.

The court upheld the legal safeguards for open-source DeFi platforms by rejecting the arguments once more.

Then, Brian, policy and legal lead at Uniswap Labs, said the ruling marks “another precedent-setting win for DeFi,” He stressed that even though the plaintiffs switched to state-level claims, the court once more determined that Uniswap cannot be held accountable for stated scams carried out by anonymous third-party token issuers, adding that it “defies logic” to hold a smart contract developer accountable for how others abuse the protocol.

As this decision marks Uniswap’s another major courtroom victory, as in February, Bancor-affiliated entities filed a patent infringement lawsuit against the exchange, which was dismissed by a New York federal judge, ruling that the patents at issue were based on abstract ideas and therefore not eligible for protection under U.S. patent law.

Following the ruling and continued legal wins, UNI is trading up about 1.5%, at $3.86, with a total market cap of $2.45 billion. Also, the 24-hour trading volume climbed over 23%, which signals increased market activity.

Illustrating the Cloudflare Wallet: The New Player in Stablecoin Payments Using x402

On August 4th, Cloudflare announced the launch of "Wallets," though the initial offering is limited to claiming a user handle. Full functionality for topping up, making payments, and using a Virtual Wallet via API keys is marked "Soon." The announcement clarifies that this handle is not yet a functional wallet. It represents a key piece in Cloudflare's broader payments strategy, alongside the Stripe Projects service (currently in open beta for agent-assisted purchases) and the Monetization Gateway for merchants (on a waitlist). The Wallet is positioned as the payer-side component for managing identity, balances, and authorization rules. While the underlying x402 protocol shows activity (75.41 million transactions, $24.24M volume in 30 days, averaging ~$0.32 per transaction), this data reflects the open network's usage, not specifically Cloudflare Wallet adoption. These metrics indicate suitability for frequent micro-payments like API calls. Cloudflare's documentation uses a $0.01 per-call example to illustrate the x402 flow: a server returns HTTP 402, the agent signs the payment, a facilitator verifies it, and the server delivers the result. Currently, developers must manage private keys and use test networks/USDC for agent payments. The Wallet roadmap aims to separate the user's Account Wallet from an agent's Virtual Wallet, adding controls for spending limits, whitelists, and per-transaction caps. This design resembles a corporate card with approval rules. However, these controls are not yet available for configuration. In summary, Cloudflare Wallet's current launch is a preliminary step. Critical details like supported stablecoins, blockchains, regions, KYC, custody, and fees remain undisclosed. The announcement primarily establishes a payer identity framework, with the full payment and agent autonomy system still under development.

TradeXYZ and Hyperliquid: Unveiling the Symbiotic Relationship Under a 50% Revenue Share

Market sentiment is cautious. AI investments are rewarded only when they drive growth without severely harming cash flow, while crypto markets face pressure from ETF outflows and rising yields. Within crypto, leadership has rotated to Solana and DEXs. Solana's ecosystem gained 8.5%, driven by tokens like META, while DEXs, led by Uniswap, rose 5.2%. A key debate centers on TradeXYZ's dominant role on the Hyperliquid exchange, where it generates over 50% of the volume in RWA perpetuals. TradeXYZ, an independent team, is required to share 50% of its HIP-3 protocol revenue with Hyperliquid. Concerns range from the sustainability of this split to Hyperliquid's long-term monetization. The argument that TradeXYZ might leave due to the 50% share is considered weak, as it would require rebuilding its entire platform and abandoning its user base, damaging its reputation. Conversely, Hyperliquid replacing TradeXYZ would signal bad faith to other builders. Their relationship is seen as symbiotic. Regarding monetization, Hyperliquid benefits not only from the 50% fee split but also from priority write fees, read fees from market makers, and second-order effects like increased USDC supply, which generates significant adjusted revenue. The more pertinent question is how both parties will transition from a growth-focused, low-fee model to a more stable, higher-fee structure.

Report: DeepSeek Resumes Financing, Pre-money Valuation at 500 Billion Yuan

Several transaction sources revealed to Caijing that AI company DeepSeek has restarted its second round of financing, aiming to raise 50 billion yuan with a pre-money valuation of approximately 500 billion yuan. The signing is planned for late August. DeepSeek completed its first funding round of 50 billion yuan in June with a valuation over 350 billion yuan, marking the largest first-round financing in China's AI large model history. The second round was reportedly paused in late July, partly due to the founder's dissatisfaction with leaked investor meeting details circulating online. It has since been restarted with a desire for a more discreet process. The second-round valuation represents a 43% increase from the first round. If successful, DeepSeek will have raised over 100 billion yuan across both rounds. Investor interest remains high; the first round saw over 100 billion yuan in expressed intent, leaving significant unmet demand. DeepSeek's fundraising scale surpasses competitors like Moonshot AI, which recently raised funds at a $31.5 billion valuation and is planning a Pre-IPO round. Market pricing for these model companies is seen more as an "option" on reaching AGI rather than based on traditional financial metrics. Regarding model development, DeepSeek recently publicly tested the DeepSeek-V4-Flash official version in late July, featuring enhanced Agent capabilities and strong performance on benchmarks. It follows a high-value, low-cost strategy, with its pricing being competitive against rivals like Zhipu GLM-5.2 and OpenAI's GPT-4o. On the OpenRouter platform, DeepSeek-V4-Flash recently ranked first in weekly token consumption. The company faces pressure in training new models, and the release timeline for the V4-Pro official version remains unannounced.

OpenAI Solves 10 Mathematical Problems, Fable 'Replicates' 5 in 24 Hours

OpenAI and Anthropic engaged in a rapid, high-stakes competition at the cutting edge of mathematics this weekend. On August 1, OpenAI researcher Sébastien Bubeck announced that their next-generation model Astra had autonomously solved 10 longstanding, open mathematical problems, providing Lean proofs and solution breakdowns. The problems, untouched for years, are considered significant; one result on non-sofic groups is deemed worthy of a top mathematics journal. The estimated marginal cost for these solutions was under $2,000. Within 24 hours, Anthropic researcher Levent Alpöge responded, stating he had independently used the publicly available model Fable to solve 5 of the 10 problems (#4-8), under clean conditions without internet access and with safeguards against data leakage. This dramatically shortens the "shelf life" of a mathematical discovery, shifting priority from years to potentially a day. The event is seen less as simple benchmarking and more as a form of peer review, testing the reliability and independent reproducibility of AI-generated proofs. The episode raises critical questions about validation in the age of AI. As these models can now produce complex proofs at low marginal cost, their outputs are often beyond public comprehension. The true challenge shifts from generating proofs to verifying, understanding, and judging their significance—a task that remains a deeply human and expert-driven endeavor. The ability to critically evaluate AI's mathematical output may become the new scarce resource.

SpaceX's First Earnings Report Exceeds Expectations, But After-Hours Trading Drops Over 7% Under Lockup Expiration Pressure

SpaceX's first post-IPO quarterly results surpassed expectations, with revenue reaching $78.14B (up 92% YoY), adjusted EBITDA of $35.38B (up 191% YoY), and a narrowed net loss of $541M. Starlink remains the profit core, contributing 55% of revenue. AI emerged as the fastest-growing segment, contributing 33% of revenue with a 247.5% YoY increase. However, shares fell over 7% after-hours due to concerns over high AI capital expenditures ($158.28B in Q2) and impending lock-up expiration for ~912M shares on August 6th. Management targets a $1T annualized revenue run-rate by end-2026, heavily reliant on AI cloud service contracts.
