BNB Chain Supports ERC-8004 for Robust Identity of Autonomous AI Agents
BNB Chain has declared its endorsement for the ERC-8004 standard, aimed at providing autonomous AI agents with a reliable and portable identity across various platforms.
[PRESS RELEASE – Dubai, UAE, February 4th, 2026]
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. This development is a significant step toward creating an open and scalable agent economy, allowing software to operate independently with consistent reputation, accountability, and user oversight.
Autonomous agents are software programs capable of making decisions, coordinating with other services, and carrying out actions on behalf of users. As these agents evolve, they will require the ability to function beyond single applications or centralized platforms. To enable this, agents need a dependable means of proving their identity.
With ERC-8004, agents are no longer limited to one application or compelled to restart their reputation upon entering a new environment. They can sustain a persistent identity as they navigate across platforms, facilitating verification of their legitimacy and providing a way to track their history over time.
To complement ERC-8004, the BNB Chain community introduces BAPs (BNB Application Proposals), a standard for the application layer. Unlike BEPs, which govern core protocol changes, BAPs delineate how applications function and communicate—spanning 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, allowing AI agents to exist as on-chain assets capable of holding assets, executing logic, engaging with protocols, and being bought, sold, or hired. This marks the initiation of a transparent and interoperable Agent Economy on BNB Chain.
Users can learn how to commence building with ERC-8004 and BAP-578 on BNB Chain in the developer documentation HERE.
