Sam Altman's World and Coinbase Launch Identity Layer for AI Agent Commerce Sam Altman's World launches AgentKit with Coinbase x402, enabling verified human-backed AI agents to transact autonomously using stablecoin micropayments. Aaron Rafferty March 22, 2026 Key Takeaways: World launched AgentKit, a toolkit that lets AI agents carry cryptographic proof they are backed by a verified human via the World ID system, integrated with Coinbase's x402 stablecoin micropayment protocol. Coinbase founder Brian Armstrong said AI agents will soon outnumber humans in transactions, while industry projections estimate agentic commerce could reach $3 to $5 trillion by 2030. The system uses zero-knowledge proofs to link multiple agents to a single verified person, enabling platforms to cap usage per human without collecting personal data. World, the identity project co-founded by Sam Altman, launched AgentKit on March 17, a toolkit that lets AI agents carry cryptographic proof of a verified human behind them. The system integrates with Coinbase's x402 protocol for stablecoin micropayments, turning AI agents into verified economic participants rather than suspicious automated traffic. AgentKit links multiple agents to a single verified person using zero-knowledge proofs. A platform can allow someone to run several agents while enforcing limits based on the underlying human, without ever collecting personal information. The system currently relies on Orb-based biometric verification, with plans to expand to NFC-enabled passports and government IDs. The timing matters because AI agents are moving from demos to deployment. Coinbase founder Brian Armstrong said AI agents will "very soon" outnumber humans in making transactions.
