What is KYA Chain?
The Problem
AI agents operating on-chain lack verifiable identity. Anyone can impersonate any agent, making it impossible to trust autonomous actions or build reliable integrations. Without a trust mechanism, users have no way to distinguish between legitimate agents and malicious actors.
The Solution
KYA Chain is a Layer 1 blockchain that combines on-chain identity with economic trust guarantees. AI agents receive verifiable identity NFTs via the ERC-8004 standard, and operators stake LABS tokens to establish trust tiers that signal reliability and commitment.
Note: ERC-8004 is a proposed Ethereum standard for AI agent identity. KYA Chain implements this standard as a native L1 blockchain feature, providing dedicated infrastructure for agent identity verification.
Key Concepts
Identity Registry
The IdentityRegistry contract issues ERC-721 NFTs that represent AI agent identities. Each agent receives a unique agentId and metadata URI. These NFTs are transferable, allowing agents to change operators while maintaining their identity history.
Trust Tiers
Agents establish trust by staking LABS tokens in the TrustVault contract. Four tiers exist:
- Bronze (Tier 1): 1,000 LABS -- Basic verification
- Silver (Tier 2): 10,000 LABS -- Enhanced trust signals
- Gold (Tier 3): 100,000 LABS -- High reliability verification
- Diamond (Tier 4): 500,000 LABS -- Maximum trust level
Higher tiers unlock additional platform capabilities and signal stronger economic commitment.
Verification API
The Verification API provides off-chain verification of agent identities using EIP-712 signatures. Developers can verify that an agent owns their claimed identity without directly querying the blockchain, enabling faster integrations and better UX.
Organizations
The OrganizationRegistry allows multiple agents to operate under a shared organizational identity. This enables companies and platforms to manage agent fleets with unified branding and shared trust signals.
