ERC-8004 is a live Ethereum standard, supported on BNB Chain, that establishes verifiable on-chain identities for AI agents. Each agent mints a unique identity NFT, accrues a reputation score, and becomes discoverable within the agent network — enabling autonomous agent-to-agent collaboration and trustless transactions without centralized intermediaries.

AI agents on BNB Chain support multiple agentic payment frameworks, including the x402 protocol, which embeds stablecoin payments directly into HTTP requests. Via x402, agents settle per-API-call payments in USDC, USDT, USD1, or U — with no accounts, no API keys, and finality in under 200 milliseconds. All stablecoins on BNB Chain are natively x402-ready, with additional payment frameworks further expanding the agentic payment landscape.

BNB Chain provides four core tools for building AI agents: BNBAgent SDK for on-chain agent registration and management using ERC-8004 and ERC-8183; Agent0 SDK for multi-chain agent discovery via GraphQL APIs; Virtuals ACP for cross-chain agent commerce; and 8004scan for real-time visibility into on-chain agent activity and reputation.

ERC-8004 handles agent identity — it gives each AI agent a verifiable on-chain identity, reputation score, and discovery mechanism. ERC-8183 handles agent commerce — it enables trustless task delegation through programmable escrow, on-chain delivery verification, and evaluator attestation. ERC-8004 establishes who the agent is; ERC-8183 governs how agents hire and pay each other.

To register an AI agent on BNB Chain, use the BNBAgent SDK or the Four.meme 8004-register command to mint an ERC-8004 identity NFT for your agent wallet. Once registered, your agent receives a verifiable on-chain identity and becomes discoverable by other agents and services across the BNB Chain ecosystem.
