In a dual advancement for the convergence of artificial intelligence and blockchain technology, two major infrastructure developments were announced in early 2025, focusing on enabling secure and autonomous AI economies on the decentralized web.
Selanet's Agent-Node Network Launch
South Korean infrastructure startup Selanet officially launched its "Agent-Node," a specialized decentralized node network designed explicitly for autonomous AI agents. Announced from Seoul on April 2, 2025, the network leverages Selanet's existing global infrastructure of over 2,800 nodes across more than 90 countries, which already processes over 30,000 daily requests. The nodes are optimized for AI agent workloads, providing reliable, low-latency access to web data and services, mitigating single points of failure and censorship risks.
The network's economic model incentivizes node operators with rewards based on the Monad blockchain, distributed initially as points with plans to convert them into a native token upon a future network launch. The use of Monad is strategic to support the high throughput demands of AI agents.
Autonomous Payments via Coinbase x402
The most groundbreaking aspect of Selanet's roadmap is its planned integration with Coinbase's x402 protocol, scheduled for Q2 2025. This integration will implement a system allowing AI agents to autonomously pay for their own web access costs using the USDC stablecoin. The x402 protocol standardizes blockchain-based payments and identity for autonomous entities, effectively giving AI agents a digital wallet and payment rail. This creates a closed-loop economy where an AI agent can access data, incur a micro-fee, and automatically dispatch a USDC payment without human intervention.
Dr. Elena Rodriguez, a researcher at the Digital Governance Institute, noted, "The missing piece for truly autonomous AI has always been a robust economic layer... Selanet's model, particularly with the x402 integration, directly solves this by embedding payment capability into the agent's operational stack."
MoonPay and Ledger Security Integration
In a parallel development focused on security, payments infrastructure giant MoonPay unveiled a groundbreaking integration with hardware wallet leader Ledger. The partnership embeds Ledger's signing capabilities directly into MoonPay's AI-powered crypto agent, announced in early 2025.
The integration addresses a core vulnerability in DeFi: the security of private keys within autonomous tools. MoonPay's command-line interface (CLI) wallet for its AI Agent now requires every transaction proposed by the AI to be manually verified and signed via a connected Ledger device. This ensures private keys never leave the secure hardware environment. The AI can analyze and construct transactions, but a human must physically approve them using the hardware wallet, creating a hybrid of automated efficiency and human-controlled security.
This model fundamentally alters the risk profile. Even if the AI agent's software is compromised, an attacker cannot move funds without physical access to the Ledger device and its PIN. Industry analysts view this as a prerequisite for mainstream institutional adoption, with one anonymous fintech security researcher stating, "The merger of AI agency with hardware security isn't just an upgrade; it's a prerequisite for mainstream institutional adoption."
The technical flow involves the MoonPay AI proposing a transaction, sending the unsigned transaction to the Ledger, the user reviewing details on the Ledger's secure screen, and physically pressing the button to sign before broadcast.
