BNB Chain Announces Support for ERC-8004 to Enable Verifiable Identity for Autonomous AI Agents
Dubai, UAE, February 4th, 2026, Chainwire
BNB Chain today announced its support for ERC-8004, a new on-chain identity standard designed to give autonomous AI agents verifiable, portable identity across platforms. The development represents an important step toward an open and scalable agent economy, where software can operate independently with persistent reputation, accountability, and user control.
Autonomous agents are software programs capable of making decisions, coordinating with other services, and carrying out actions on behalf of users. As these agents become more capable, they will need to operate beyond single apps or centralized platforms. For that to be possible, agents require a reliable way to prove who they are.
Under ERC-8004, an agent is no longer confined to one application or forced to restart its reputation every time it enters a new environment. Instead, it can maintain persistent identity as it moves across platforms, enabling other agents, services, and users to verify its legitimacy and track its history over time.
To complement ERC-8004, the BNB Chain community introduces BAPs (BNB Application Proposals), a new standard for the application layer. Unlike BEPs, which govern core protocol changes, BAPs define how apps work and communicate – covering interfaces, wallet and identity conventions, token and NFT standards, and app-to-app interoperability.
The first BAP, BAP-578, launches the Non-Fungible Agent (NFA) standard, enabling AI agents to exist as onchain assets that can hold assets, execute logic, interact with protocols, and be bought, sold, or hired. This marks the first step toward an open, predictable, and interoperable Agent Economy on BNB Chain.
Users can explore how to start building with ERC-8004 and BAP-578 on BNB Chain in the developer documentation HERE.
