Circle Arc Mainnet Builds for AI Agents Ahead of Demand
Circle’s Arc launched with agent wallets and sub-cent USDC payments. The tools are real. The agent demand they were built for is still small.
Grass Revenue and the Home Internet Behind AI Training Data
An outside review puts Grass revenue below the company’s own July figure. What the numbers prove about AI data demand, and which nodes carry the traffic.
x402 Security: The Facilitator Is the Weak Point
Researchers tested 15 x402 payment facilitators in 2026. Every one violated security rules. The protocol delivers goods before it takes the money.
Crypto Wallet MCP Servers: The Private Key Boundary
A malicious PyPI package shipped a crypto wallet MCP server that leaked Solana private keys. The clean GitHub repo showed nothing wrong.
Sandboxing AI Agent Wallets With Multi-Sig Guardrails
A single compromised session moved $150,000 out of an AI agent’s wallet in May 2026, no stolen key required. This case study covers how multi-sig and threshold signing close the gap that spending limits and session caps leave open, and where those defenses introduce new failure modes of their own.
Why ERC-8004 Doesn’t Secure an Agent’s ERC-6551 Wallet
ERC-8004 and ERC-6551 solve different problems: one provides an agent with on-chain identity and reputation, while the other provides a token-bound wallet. Conflating the two can hide a real custody risk, because neither standard is designed to prevent prompt injection from influencing a compromised signing workflow.
AI Agent Wallet Exploits: How Prompt Injection Reaches Your Keys
Autonomous crypto agents can lose funds without their private keys being stolen. This analysis examines how prompt injection can influence transaction authority, what sandboxed execution can block, and where current defenses still fall short.
Bittensor Subnets vs. Fetch.ai uAgents: How They Differ
Bittensor and Fetch.ai’s uAgents get lumped into the same ‘decentralized AI’ category constantly, but they solve completely different problems. Here’s what actually separates a subnet-based incentive market from a Python agent framework, and where each one’s real risks lie.
ERC-8004 Adoption: What the Agent Numbers Actually Show
ERC-8004 has drawn more than 170,000 registered AI agents across Ethereum, BSC, and Base within months. New empirical data reveal how few expose a live service endpoint, and how coordinated Sybil behavior is already undermining on-chain reputation.
Prime Intellect: Why It Has No Token
Prime Intellect just raised $130M at a $1B valuation without launching a token, while unrelated copycat coins trade under its name on two different chains. Here’s what the company actually built, and why conflating the two is costing people money.
