April 21st – Cobo AI Growth Lead Brad Bao spoke at the offline event “Decoding Web 4.0: When AI Agents Take Over On-Chain Permissions,” where he revealed Cobo is restructuring its Agent fund control logic via a structured permission system. In its product, the user-Agent relationship is no longer simple wallet authorization but defined by an executable “Agreement” that sets clear permission boundaries. This Agreement includes at least four core components: Intent, Path, Rules, and Termination. It shifts the original “all-or-nothing” permission control to a negotiable, auditable, and revocable fine-grained governance mechanism. On the technical front, Cobo integrates MPC (Secure Multi-Party Computation) to ensure funds remain under user control even amid Agent anomalies, system attacks, or mnemonic injection risks—no single entity can bypass constraints to transfer assets independently. Brad Bao emphasized that under this architecture, Agents have sufficient autonomy to complet

On April 21, Brad Bao, Growth Lead at Cobo AI, spoke at an offline event titled “Decoding Web 4.0: When AI Agents Take Over On-Chain Authority.” He shared that AI agents’ involvement in fund management and asset allocation has evolved from concept to reality—so the question of whether AI agents will manage funds is no longer up for debate. As more agents directly connect to wallets to execute transactions, the industry has seen instances of funds not reaching their intended destinations as expected. In response, the team is continuously logging the issues and risks AI agents encounter in real-world transactions within its experimental system, driving improvements to relevant mechanisms. Bao noted the industry’s core tension right now: If an AI agent lacks autonomy, it’s no more valuable than traditional automated trading tools. But if it lacks verifiable determinism, humans won’t feel confident entrusting their funds to these agents. This “autonomy vs. determinism” tension is eme

**Crypto Extortion Attack Probed in France** April 21 — French police are investigating a violent cryptocurrency "extortion attack" at a Paris-area home. Three suspects disguised as police officers broke into the residence, threatened and restrained a couple in their 50s at knifepoint, and forced the husband to transfer roughly $1 million in Bitcoin. The victims sustained injuries; the husband was bound, and the suspects fled the scene in a car after the theft. The incident highlights a shift in crypto security threats: from digital breaches to physical coercion targeting holders. By posing as law enforcement to create emergencies and psychological intimidation, criminals force victims to authorize transactions voluntarily — bypassing technical defenses like wallet encryption entirely. Data shows such attacks spiked in 2025: up 75% from 2024, with France as a key hotspot. 2025 losses topped $40.9 million (a 44% year-over-year increase). Along with kidnappings, physical assau

April 21st — On-chain analyst Ai Auntie (@ai_9684xtpa) notes that Solana’s well-known meme trader Cooker (@CookerFlips) has been continuously scalping the ASTEROID token. Around 10 AM today, amid FUD, Cooker sold roughly $160k worth of ASTEROID between $0.0002714 and $0.0003161, triggering a temporary price dip to $0.0002. Subsequently, the trader tweeted that the “FUD impact was less than expected” and bought back 1.78 billion ASTEROID tokens between $0.000359 and $0.00048.

On April 21, cryptocurrency market analyst Axel noted Bitcoin’s 30-day net flow turned negative in early March, peaking at an outflow of 300,000 BTC on March 25. As of April 21, the net outflow remains -98,000 BTC. Over the same period, BTC reserves on exchanges dropped from 2.786 million to 2.681 million—posting a seven-week consecutive decline with a total reduction of over 105,000 BTC. Notably, there was no panic inflow during Bitcoin’s April price pullback, indicating tokens are continuing to settle with long-term holders. The current trend is seen as a signal of coordinated accumulation, though investors should be cautious about the potential risk of net flow turning positive.
