ERC-8004 is a standard that provides on-chain identity for AI agents: each agent has an identifier on the blockchain, with associated behavioral history, reputation, and permissions — enabling agents to verify each other's trustworthiness instead of blind trust.

x402 is a protocol that enables AI agents to autonomously pay each other or pay for services in real-time, without human confirmation for each transaction. Combined with ERC-8004 identity and programmable wallets, it creates the foundation for an 'agent economy.'

Why are B.AI and Virtuals related to ERC-8004/x402?

AI agent infrastructure projects like B.AI integrate ERC-8004 (identity) and x402 (payments) so agents can operate economically autonomously; this is also the underlying logic behind agent launchpads like Virtuals. These two standards form the foundational layer of the 2026 agent economy narrative.

What are the risks of investing based on agent standards?

Open standards mean high competition; winners depend on network effects, not early announcements. Key risks: projects claiming 'compatibility' on paper without real usage, tokens priced on excessive expectations, and fake tokens. Monitor real agent/transaction numbers. DYOR.

ERC-8004 & x402: The Infrastructure Standards Behind 'Autonomous Economic AI Agents' Powering B.AI, Virtuals 2026

Cập nhật: 16 tháng 5, 2026

When people say "AI agents will hire services, pay fees, and collaborate autonomously," a technical question rarely gets answered: how does an agent prove who it is, and how do agents pay each other without humans signing each transaction? The 2026 answer lies in two emerging standards: ERC-8004 for on-chain identity and x402 for autonomous payments. This is the infrastructure layer behind hot projects like Justin Sun's B.AI and Virtuals. This article explains clearly for Vietnamese investors: what these two standards are, why they matter
