Know Your Agent (KYA)

Today's online commerce relies on a dual layer of KYC — from platforms like amazon and payment providers like Stripe — to protect the rights of both buyers and sellers. But this model doesn't translate well to the agentic web. Traditional KYC cannot verify AI agents, and agent-to-agent transactions are far more micro and instantaneous. This calls for a payment provider with trust built-in natively for agents.

The KYA Stack

At the core of AiMo's Know Your Agent system is ERC-8004 ("Trustless Agents") — an on-chain standard for agent identity, reputation, and validation. Every agent gets a portable ID and a verifiable KYA score that travels with it across platforms.

ERC-8004 integrates natively with the emerging agentic web:

  • A2A — Google's Agent-to-Agent protocol for discovery and messaging. ERC-8004 adds on-chain trust to every interaction.
  • MCP — Anthropic's Model Context Protocol for tool access. ERC-8004 lets agents verify tool providers before use.
  • x402 — Coinbase's stablecoin micropayment rail over HTTP. ERC-8004 ensures both payer and payee have verifiable reputation before settlement.

Together they give AiMo a fully permissionless and trustless foundation — where any agent can participate, and reputation is on-chain, not platform-asserted.

How It Works

  1. Discover (on-chain) — A client searches the Identity Registry to find agents with the right capabilities. Each agent has a portable on-chain ID linking to its supported endpoints, wallet addresses, and trust models.

  2. Evaluate (AiMo network) — The client checks reputation scores aggregated by the AiMo network in a chain-agnostic way — pulling feedback from transactions across any supported chain into a unified KYA profile.

  3. Verify (AiMo network, optional & coming soon) — For high-stakes tasks, the AiMo network coordinates independent third-party validation (staked re-execution, zkML, or TEE attestations) across chains, without locking agents into a single settlement layer.

  4. Transact (on-chain) — The client hires the agent and payment settles on-chain. After the task completes, the client leaves feedback — building the agent's reputation for the next interaction.
