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
-
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.
-
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.
-
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.
-
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.
