The Definitive Hub for AI Agents & Crypto Rails

Learn how autonomous AI agents use self-custodial smart accounts (ERC-4337), HTTP 402 micropayments (x402), decentralized GPU networks, and on-chain DeFi execution.

Core Crypto & Agent Architecture Pillars

• Autonomous Agent Wallets & Machine Payments — How AI Agents Hold Capital, Enforce Session Policies, and Execute Sub-Cent Micropayments
• Decentralized AI (DeAI) & Compute Settlement — Token-Incentivized Intelligence Networks, Decentralized GPUs, and Verifiable Inference
• Agentic DeFi & Autonomous Liquidity Routing — Multi-Agent Swarms, Algorithmic Arbitrage, Flash-Loan Safety, and Autonomous Treasury Management
• Agent Identity, Reputation & On-Chain Governance — ERC-6551 Token Bound Accounts, Cryptographic Attestations, and Verifiable Agent Provenance
• The Crypto-Native AI Agent Developer Stack — Frameworks, SDKs, Tool Calling, and WebMCP Infrastructure for Building Blockchain Agents

Step-by-Step Developer Tutorials

• Building an Autonomous On-Chain Agent with Coinbase AgentKit & Base — Learn how to give any LLM agent (LangChain / OpenAI / Claude) a self-custodial smart wallet on Base with automatic gas sponsorship, token swaps, and contract deployment.
• Implementing HTTP 402 Micropayments for Agent-to-Agent APIs — Set up an HTTP 402 Payment Required paywall that accepts instant USDC payments from autonomous AI bots without requiring credit card subscriptions or manual API key generation.
• Configuring ERC-4337 Smart Accounts with Bounded Session Keys — Set up an enterprise-grade ERC-4337 Smart Account with fine-grained session key policies restricting autonomous bot spend, allowed contract targets, and expiration timestamps.
• Building a Verifiable DePIN Research Agent with ElizaOS — Deploy an autonomous market intelligence agent on ElizaOS that queries decentralized DePIN nodes, computes cryptographic market signals, and publishes attestations on-chain.
