BNB Chain Adopts ERC-8004 Standard for Agent Identity and Reputation
BNB Chain Adopts ERC-8004 Standard for Agent Identity and Reputation
🤖 Agents get identity cards
BNB Chain now supports ERC-8004, a standard that provides AI agents with verifiable onchain identities through NFT-based registries.
Key features include:
- Unique agent IDs and metadata registration
- Onchain discoverability and portability
- Reputation tracking over time
- Integration with BAP-578 (Non-Fungible Agent token standard)
This infrastructure enables agents to establish trust, build credentials, and interact with other agents in a transparent ecosystem. The standard works alongside ERC-8183 for task delegation and x402 for payments, creating a complete framework for autonomous agent operations.
Then, commerce What if one agent needs to hire another to get a job done? ERC-8183 makes that possible. Trustless task delegation with programmable escrow, on-chain delivery verification and evaluator attestation
BNBAgent SDK is now live on BNB Chain testnet. It’s the first live implementation of ERC-8183 and introduces a framework for running AI agents fully onchain with identity, escrow, and decentralized verification built in. Here’s what it changes for builders 🧵 👇
First, Identity & Trust with ERC-8004 This gives agents a verifiable onchain identity through an NFT-based registry. Enabling unique agent IDs, metadata registration, discoverability, portability and reputation over time.
First, identity BNB Chain supports ERC-8004, enabling agents to mint a unique identity NFT, build a verifiable reputation score, and be discoverable on-chain. BAP-578, the Non-Fungible Agent token standard, is also native on BNB Chain
The AI Agent Economy has arrived on BNB Chain. We are proud to announce the deployment of the ERC-8004 infrastructure, the standard for Trustless Agents, on both BSC Mainnet and Testnet. This brings verifiable identity and on-chain reputation to autonomous agents 👇
This is how the life of your agent would look like: → Agent gets an identity (ERC-8004) → Agent gets paid or pays others (x402) → Agent hires and delegates to other agents (ERC-8183) → Agent builds reputation over time (8004scan) Verifiable, transparent & onchain
BNBAgent SDK Launches on Mainnet with Modular Framework for AI Agents
**BNB Chain has launched the BNBAgent SDK on mainnet**, providing developers with a standardized framework for building AI agents with built-in identity, commerce, payments, and memory capabilities. **Key features:** - Modular standard that eliminates the need for developers to build infrastructure from scratch - Enables AI agents to be interoperable and economically active onchain - Supports autonomous agent-to-agent commerce at scale **Why it matters:** Previously, teams had to piece together fragmented solutions themselves, which slowed development and increased complexity. The SDK addresses this by offering production-ready infrastructure specifically designed for agentic applications. Developers can now deploy AI agents that trade, hire, pay, and collaborate autonomously without human intervention.

BNB Greenfield Enables Persistent Memory for Blockchain Agents
BNB has introduced a memory and storage solution through Greenfield that allows blockchain agents to maintain persistent memory across different runtime sessions. **Key Features:** - Stores task history, outputs, and model state - Enables agents to preserve continuity over time - Eliminates the need to restart from scratch with each run This memory component is part of the BNB Agent SDK's four modular building blocks, which also include Identity & Trust, Commerce/Escrow Payment, and Memory & Storage. Each module is opt-in and can be deployed independently, giving developers flexibility in implementation.
MPP + x402 Enable Autonomous Agent Payments for APIs and Services
A new payment system combining MPP and x402 protocols now allows AI agents to autonomously pay for APIs, tools, and services during execution. **Key capabilities:** - Per-request payments without manual intervention - Session-based payment options - Gas sponsorship support - Built-in replay protection This builds on the x402 HTTP 402 protocol introduced earlier, which eliminated the need for API keys by enabling agents to pay directly per request using their own wallets.
BNB Chain Teases Agent Development Launch for May 18, 2026
BNB Chain has announced an upcoming development related to building agents on their platform, scheduled for May 18, 2026. **Key Details:** - The announcement hints at new capabilities for agent development on BNB Chain - Launch date confirmed for May 18, 2026 - Follows previous initiatives encouraging developers to build on the platform This continues BNB Chain's pattern of expanding developer tools and capabilities on their Layer-1 and Layer-2 ecosystem.
