X402 Payments
The foundation for a secure, monetized internet of agents where AI systems can autonomously transact without human intervention. The Vision Today’s internet is built for humans clicking “buy now” buttons. Tomorrow’s internet will be billions of AI agents autonomously discovering, negotiating, and paying for services in real-time. X402 creates the economic layer that makes this possible—where every API call, every computation, every byte of data can be instantly monetized and secured behind intelligent paywalls. Current Reality- Base Sepolia testnet with USDC - Proving the concept works
- Agents successfully paying for APIs, AI services, and data storage
- Zero human intervention required
- Multi-Network Support - Lightning Network for instant Bitcoin micropayments, Optimism/Arbitrum/Polygon for low-cost Ethereum transactions, enabling agents to choose the most efficient payment rail for each transaction
- Intelligent Paywalls - Services can dynamically price based on demand, quality, and consumer reputation. Premium agents pay premium prices for premium data. Budget agents access basic tiers. All automated.
- Economic Security - Bad actors can’t spam services because every request costs real money. DDoS attacks become economically infeasible. Quality of service improves when there’s skin in the game.
- Agent Reputation Economy - Agents build payment histories and credit scores. Trusted agents get better rates, faster service, and access to exclusive APIs. The system self-regulates through economic incentives.
- Frictionless Commerce - No subscriptions, no invoices, no billing departments. Agents pay per use, in real-time, with sub-cent precision. Services scale revenue with usage automatically.
AP2 Protocol
The trust layer for agent commerce—solving the fundamental crisis of “who authorized this purchase?” when AI agents transact autonomously. The Problem Today’s payment systems assume a human is clicking “buy” on a trusted website. When an autonomous agent initiates a payment, three critical questions emerge that current systems cannot answer:- Authorization - How do we prove the user actually gave the agent permission for this specific purchase?
- Authenticity - How can merchants trust the agent’s request reflects true user intent, not an AI hallucination or error?
- Accountability - If fraud occurs, who’s responsible? The user? The agent developer? The merchant? The bank?
- Intent Mandate - “Buy concert tickets when they go on sale, max $200” - Pre-authorized rules for human-not-present scenarios. The agent has provable authority to act within defined constraints.
- Cart Mandate - “Yes, buy these exact shoes for $89.99” - Explicit approval for human-present scenarios. Your cryptographic signature on the exact items and price. What you see is what you pay for.
- Payment Mandate - Shared with payment networks to signal AI agent involvement and assess transaction context for fraud prevention.
- Smarter Shopping - “Find this jacket in green, willing to pay 20% more” - Agent monitors availability and executes the moment it’s found, with provable authority.
- Coordinated Purchases - “Book flight + hotel in Palm Springs, $700 budget” - Agent negotiates with multiple merchants simultaneously, executes both bookings atomically with signed mandates.
- Personalized Commerce - Merchants’ agents can create custom bundle offers knowing the user’s intent is cryptographically verified, turning queries into higher-value sales.
- ✅ Core protocol complete (15 data types, mandate framework, cryptographic signing)
- 🚀 X402 integration for crypto payments (with Coinbase, Ethereum Foundation, MetaMask)
- 📋 Traditional payment processors (Stripe, PayPal) coming next
- 🌍 Designed for global scale: Cards today, real-time bank transfers (UPI, PIX) and digital currencies tomorrow
mTLS Support
Securing the communication channel between agents—because knowing who you’re talking to isn’t enough if someone can eavesdrop on the conversation. The Problem DIDs solve identity: Your agent can cryptographically prove “I am Agent X owned by User Y.” But identity alone doesn’t secure the communication channel. When Agent A talks to Agent B:- Eavesdropping - Without encryption, anyone on the network can read the messages, including sensitive data, payment information, or proprietary business logic.
- Man-in-the-Middle Attacks - An attacker can intercept and modify messages in transit, changing “pay 1000” without either agent knowing.
- Impersonation - Even with DIDs, without mutual authentication of the transport layer, a malicious server can pretend to be Agent B and steal Agent A’s credentials or data.
- Mutual Authentication - Both the client agent and server agent present certificates and verify each other’s identity. Not just “the server is who it claims to be” but also “the client is authorized to connect.”
- End-to-End Encryption - All communication is encrypted in transit. Even if someone intercepts the network traffic, they see only encrypted gibberish, not the actual agent messages.
- Certificate-Based Trust - Certificates are issued by trusted authorities and tied to agent DIDs. An agent can’t fake its identity because it can’t forge a valid certificate signed by the authority.
- Certificate Issuance - When an agent registers with Hydra, it receives an mTLS certificate bound to its DID. This certificate becomes the agent’s cryptographic identity for secure connections.
- Automatic Renewal - Certificates expire and rotate automatically. Agents don’t need manual intervention—Hydra handles the lifecycle.
- Revocation - If an agent is compromised, its certificate can be instantly revoked across the network. No more trusting a bad actor.
- Zero-Trust Architecture - Every connection requires fresh certificate validation. Even if an agent was trusted yesterday, it must prove itself again today.
- Confidential Transactions - Payment details, API keys, proprietary algorithms—all transmitted securely between agents without risk of interception.
- Regulatory Compliance - Financial services, healthcare, legal—industries with strict data protection requirements can safely deploy agent networks.
- Enterprise Adoption - Corporations can run agent swarms across public networks knowing their internal communications are encrypted and authenticated at the transport layer.
- Defense Against Nation-State Attacks - Even sophisticated attackers with network access can’t decrypt or modify agent communications without breaking modern cryptography.
