Beating AI Express News: AI Agents can now independently seek assistance from other Agents. Messaging infrastructure firm Photon announced it is integrating A2A (Agent-to-Agent communication and collaboration) into iMessage group chats. Users only need to assign a task, and their personal Agent will locate other Agents, retrieve their phone numbers, and add them to the same group chat. For instance, if a user wants to organize a team trip, their personal Agent can find Agents specializing in accommodation, ride-hailing, and restaurant bookings to coordinate the itinerary together in the group. Users can monitor the conversation and join discussions at any time. Photon dubs this model "Agent-to-Agent-to-Person", referring to collaboration between multiple Agents and human users. Technically, the new feature is built on the A2A protocol and its Agent discovery mechanism, which was originally proposed by Google. Photon previously allowed AI Agents to send and receive messages via iMessage; this update adds the capability to proactively find other Agents and create group chats. Photon recently closed a $4.5 million seed funding round. Founder Daniel Tian hopes every enterprise will offer its own Agent, enabling direct connections between Agents.

Dragonfly Capital managing partner Haseeb Qureshi criticized Ethereum researcher Justin Drake’s proposed "Bunker Mode" as "cryptographic doomsdayism", arguing that once AI breaks through cryptographic signature mechanisms, simply migrating assets to new addresses will not fundamentally solve the problem. If assets in other addresses are stolen and sold off en masse, even if migrated assets are temporarily safe, their value could be severely impacted. Qureshi proposed that blockchain networks establish a "cryptographic recovery mode", allowing users to pre-bind hash-based alternative signature schemes to their addresses, with validators able to forcibly activate an asset recovery mechanism if existing cryptographic signatures are compromised. Per Glassnode data, addresses holding roughly 6.26 million BTC face public key exposure risks, accounting for over 31% of Bitcoin’s total supply. Of these, around 4.33 million BTC’s risk stems from address reuse, which can be eliminated by migrating to new addresses; another 1.94 million BTC faces risks due to address format issues. Exchanges’ related risk exposure nears 1.8 million BTC, representing roughly 57% of their total BTC holdings. Earlier, Justin Drake warned that AI could accelerate the cracking of the Elliptic Curve Digital Signature Algorithm (ECDSA) used in crypto wallets, with worst-case risks potentially emerging in months rather than years. Ethereum co-founder Vitalik Buterin also noted that risks from AI accelerating mathematical research should be taken seriously, but does not recommend users hastily transferring their assets.

CZ issued a post warning Ledger hardware wallet users to remain vigilant, especially those who purchased devices recently. Based on available information, the incident appears limited to the supply chain, involving one vendor, with a small number of users possibly purchasing counterfeit or tampered Ledger devices. CZ stated that Ledger is a long-standing, highly secure hardware wallet brand in the industry, but such incidents can still occur. He called on the BNB ecosystem and the entire crypto industry to assist in tracking and recovering the stolen funds. Earlier, Ledger confirmed it is investigating a fund theft incident involving users in Southeast Asia, where affected users purchased devices via reseller CryptoBilis. Ledger has ordered CryptoBilis to suspend sales and shipments, and advised users who bought devices through the reseller in the past 90 days not to initialize their devices for now; if setup is already complete, they should create a new Ledger signing device using a new mnemonic phrase and transfer their assets to the new wallet. On-chain investigator Specter estimates the incident has led to the theft of hundreds of wallets across Bitcoin, Ethereum, and Tron networks, with losses exceeding $86 million. Security researcher tanuki42 previously estimated losses have surpassed $72 million, noting the figure is still rising. At present, the specific cause of the incident and whether the involved devices have security vulnerabilities remain unconfirmed pending investigation.

Crypto market analyst CW stated in a recent post that despite Bitcoin’s recent price decline, demand-side indicators still show positive trends. Futures demand saw a slight pullback from the previous day, while spot demand’s negative balance narrowed, keeping overall demand in a relatively positive range. Spot demand, which had remained in negative territory, is now approaching positive territory. Once spot demand turns positive, Bitcoin will gain strong upward momentum.

According to monitoring by Ai Yi, whale address 58bro.eth deposited 3,000 ETH to OKX one hour ago, worth approximately $7.53 million. On-chain data shows the ETH was withdrawn five days prior at a price of $2,702.35; by the time of deposit, ETH’s price had fallen to $2,512.13, a roughly 7% drop. Calculated based on the price difference, the book value of this batch of ETH has shrunk by around $570,000.
