Japanese tool and machinery company Trusco Nakayama Corp. has introduced the “Do Hiemon Box,” a body-cooling unit priced at about 1.5 million yen, or roughly $9,500, for use in places where air conditioning is unavailable. The stainless steel unit stays at 15°C and blows 5°C air to cool users quickly, with the stated goal of preventing heatstroke and other heat-related illness. The product has sold about 200 units so far, according to the report, with deployments at steel plants, construction sites, golf courses, universities, leisure facilities, and disaster shelters. After an earthquake in Kumamoto last week, the company also sent multiple units to evacuation shelters. ABMedia said the product reflects rising demand for specialized cooling equipment as summer temperatures in Japan repeatedly top 35°C and workplace heat-safety rules tighten. Trusco, which has a market value of about $1 billion and around 3,300 employees, also said it has received inquiries from overseas markets including Germany and the United States, pointing to possible cross-border demand for climate adaptation products.

ChainFeeds published its Daily Research roundup on Aug. 4, bringing together five separate pieces on Bitcoin custody, miner economics, market structure, meme trading narratives and hardware wallet security. The package spans commentary from Stacks founder muneeb.btc on the Coldcard incident, a Bitcoin Magazine analysis of a prolonged miner capitulation cycle, a Deep Tide TechFlow piece on the crypto market’s third straight quarterly decline, a BlockBeats discussion of Binance Alpha’s move into U.S. stock meme tokens, and a Smart Ape review of how major hardware wallets generate randomness. The Coldcard section argues for diversification across Bitcoin ETFs, multisig custody and fully self-managed setups, while also warning that quantum-computing risk should be treated seriously and that Bitcoin companies should work more closely with outside security firms such as Trail of Bits and Asymmetric Research. The mining report says difficulty has fallen 19.9% from its peak, making it the third-largest drop since ASIC machines displaced GPU mining, even as some listed mining stocks have rallied. The market piece points to shrinking stablecoin supply, weaker spot volumes, a 23.4% drop in DeFi TVL and continued underperformance by BTC and ETH versus U.S. equities. The wallet security review compares multi-source and single-source entropy models across brands including Trezor, BitBox, Foundation, Keystone, Jade, Ledger, Tangem, ELLIPAL, SafePal and Coldcard.

STONKBROKER, a project in the Robinhood ecosystem, hit a fresh high in market value after rolling out several product updates, according to BlockBeats. The move came as on-chain activity tied to Robinhood has dropped sharply in recent days, with BlockBeats attributing the slowdown to an oversupply of token launch platforms and competition from the BSC ecosystem for stock-meme market share. The project recently launched a new launchpad designed to incubate ecosystem projects and introduced Broker Box, a quasi-FWA feature that packages stock tokens into a card-draw format. BlockBeats said those updates drew attention from key opinion leaders and the wider community, including Ansem, helping push the token higher. Data cited from GMGN showed STONKBROKER’s market cap briefly exceeded $48 million earlier on Aug. 3 before easing to $42.8 million, still up more than 20% over the past 24 hours. That valuation places it as the second-largest project by market cap on the Robinhood chain, behind only meme coin CASHCAT at $43.32 million. Its related STONKBROKER NFT collection also reached a new high, with the floor price at 6.3 ETH. BlockBeats added that the project still carries significant uncertainty and high price volatility.

MoonPay has introduced PayBox, a non-custodial payment vault that lets users carry out crypto transactions and online purchases through AI assistants including ChatGPT and Claude. The product supports Solana as well as Ethereum Virtual Machine-compatible networks, extending its reach across multiple blockchain environments. PayBox works through custom connectors and natural-language commands, allowing users to instruct AI tools to handle specific payment and transaction tasks. To control those permissions, users can set Passkey-based authorization and spending limits. The product also supports a range of use cases beyond basic transfers, including digital asset purchases, cross-chain bridging, and commercial payments such as booking flights and restaurant reservations. For security, private keys are stored using multi-party computation shard storage, according to the report cited by Techub News from crypto.news.

Robinhood reported the strongest quarter in its history, posting $1.31 billion in net revenue, $573 million in net income, diluted EPS of $0.62, and total platform assets of $369 billion. One of the standout figures came from its prediction market business, where event contracts generated $156 million in revenue, topping both crypto and equities for the first time. CEO Vlad Tenev also highlighted Robinhood Chain, saying its DEXs have processed more than $12 billion in volume, the network reached 100 million transactions at record speed, and TVL stands around $325 million. Outside the company, crypto markets were largely flat after the FOMC, with BTC at $64.8K, while SEC Chair Paul Atkins said the agency is prepared to draft crypto market rules on its own if the CLARITY Act does not move forward. The broader update also covered ETF flows, Coinbase ahead of earnings, MoonPay’s PayBox launch, Binance US’s plan to seek DCM status, and activity across meme coins, DeFi protocols, and NFTs.

MoonPay has launched PayBox, a payment vault that connects to Claude and ChatGPT and lets AI agents complete transactions after user approval. The system stores crypto wallets and payment cards in a secure vault, lines up transactions inside the chat flow, and uses a passkey on the user’s device to authorize payment. At launch, PayBox supports restaurant reservations, flight bookings, shopping across major online retailers, token swaps, cross-chain fund transfers, and routing assets into DeFi protocols such as Aave. It starts with support for Solana and seven Ethereum-compatible chains: Ethereum, Hyperliquid, Tempo, Base, Robinhood Chain, Arbitrum, and Polygon. MoonPay also said PayBox works with x402, the open payments protocol developed by Coinbase and later donated to the Linux Foundation, now supported by Visa, Mastercard, Stripe, Shopify, AWS, and Anthropic. The infrastructure comes from Sodot, the Israeli key management startup MoonPay acquired in April for roughly $100 million in an all-stock deal. According to MoonPay, wallet keys are split with MPC and stored across TEEs so no single party, including MoonPay or the AI agent, can access a full key or sign on its own.

MoonPay has rolled out PayBox, a new AI payments tool that can be connected to ChatGPT or Claude, according to The Block. The product is designed to let AI assistants prepare transactions for activities such as booking flights, reserving restaurants, and making online purchases. Users can either require passkey approval for every transaction or set spending limits that allow the AI to complete payments on its own. PayBox combines a crypto wallet with a payment card and supports cross-chain transactions based on the x402 agent payment standard. At launch, it works with Solana and a range of EVM-compatible networks, including Ethereum, Hyperliquid, Tempo, Base, Robinhood Chain, Arbitrum, and Polygon. MoonPay said it plans to add support for more AI platforms and DeFi features, including token swaps and perpetual futures trading, within the next month. The company also said wallet private keys are protected through MPC and TEE, while card information is stored in a way that lets AI agents complete purchases without accessing the underlying card details.

A broad set of crypto and AI developments landed over the past day, spanning regulation, market structure, fundraising, protocol upgrades and security incidents.
