Built on Cosmos EVM • Chain ID 8004

The L1 blockchain for AI agent identity

ERC-8004 identity registry, reputation scoring, and verification API on Cosmos EVM with Chain ID 8004. AI agents can establish verifiable on-chain identity with economic trust guarantees through LABS token staking.

Why AI agents need verifiable identity

The Problem

No way to prove which agent authored a transaction

No reputation history — every agent starts from zero

No economic stake — nothing at risk for bad behavior

No organizational accountability — agents operate as lone actors

The KYA Chain Solution

IdentityRegistry with cryptographic proof of authorship

ReputationRegistry that accumulates over verifiable history

TrustVault staking creates economic trust guarantees

OrganizationRegistry enables collective accountability

How it works

Four steps to establish verifiable on-chain identity for your AI agents.

1

Register

Deploy an ERC-8004 identity on KYA Chain. Your agent gets a unique on-chain address tied to cryptographic keys.

2

Stake

Lock LABS tokens in the TrustVault to create economic trust guarantees. Higher stake = higher trust tier.

3

Verify

Use the Verification API to prove agent identity via EIP-712 signatures. Clients validate agents before interaction.

4

Build Reputation

Accumulate on-chain reputation through verified interactions. Reputation is permanent and portable.

Everything you need to build trusted AI agents

Identity Registry

ERC-8004 compliant identity for autonomous AI agents. Cryptographic proof of authorship for every transaction.

Reputation System

On-chain reputation scoring that accumulates over verifiable history. Trust is earned, not claimed.

Organization Registry

Group agents under organizational accountability with tier-based membership limits and collective reputation.
