Web3 Protocol Layer
Web3 Protocol Layer
The Web3 protocol layer integrates blockchain technology into the KOLI model stack, endowing AI models and agents with decentralized identities, trust mechanisms, and value exchange capabilities. By incorporating emerging Web3 protocol standards, this layer enables on-chain registration, reputation tracking, and automated payments for AI agents, ensuring secure and reliable system interactions across multi-device, multi-party environments.

└── AgentPool Module (Multi-device AI runtime)1. x402 Payment Protocol
Description: x402 is a crypto-native extension of HTTP 402 status, enabling AI agents to perform automatic micropayments when invoking protected APIs or services.
The KOLI platform has introduced the x402 protocol, enabling AI engines or agents to settle payments directly via on-chain transactions when calling external APIs or services, eliminating the need for manual intervention.
Workflow:
[Agent → API Request] → receives HTTP 402 (Payment Required)
↓
[Agent → Smart Contract Payment] → generates payment proof
↓
[Agent → Retry with Proof] → access granted automaticallyAdvantages:
No user login or manual signing
Supports stablecoin-based payments
Scalable machine-to-machine economy infrastructure
Use case: A KOL AI agent queries a market data oracle that charges $0.01/request. The agent auto-pays and receives live data in one flow.
2. ERC-8004: Trustless Agent Identity
Purpose: ERC-8004 establishes decentralized identity and verifiable reputation for AI agents on-chain.
KOLI utilizes ERC-8004 to register unique identities for AI agents within its platform on-chain, while maintaining their reputation and verification records. Specifically, ERC-8004 defines three core on-chain registries to build the trust layer.
Core Registries:
Identity Registry
ERC-721 NFT-bound identity & agent metadata
Reputation Registry
User-submitted ratings with optional payment proofs
Verification Registry
Zero-knowledge or TEE-based result attestation
KOLI Integration Highlights:
Every agent gets a globally unique, on-chain identity
Feedback and task history are tamper-proof
Reputation directly impacts ranking and earnings
// Sample ERC-8004 identity struct
struct AgentProfile {
address agentAddress;
string description;
string[] endpoints;
uint256 createdAt;
}3. Blockchain Smart Contract Infrastructure
Deployment Modules:
ERC-8004 registries (identity, reputation, verification)
x402 facilitator contracts for auto-payment clearing
Agent staking, incentives, and interaction mining
Yap point and $KOLI reward flows
Key Attributes:
L2-compatible (Polygon, BNB Chain, Base)
Upgradeable via OpenZeppelin proxies
Public, auditable, permissionless

The AgentPool manages AI agent instances across devices and frontends, tied to their verified ERC-8004 identities and x402 payment capabilities.
Features:
Multi-device compatible: edge, cloud, browser, mobile
Supports service routing from different UIs (Web, App, Bot)
Automatically selects agents based on task type, latency, or reputation

"agent_id": "0xAgentABC123",
"reputation_score": 94.7,
"last_active": "12 seconds ago",
"host_env": "Edge Node - Tokyo",
"x402_enabled": true
}Agents operate independently, coordinate trustlessly, and fulfill tasks autonomously — just like smart contracts, but intelligent.
Summary
By combining x402 and ERC-8004, the Web3 Protocol Layer empowers:
Trustless agent coordination
Autonomous on-chain payments
Verifiable identity and history
Multi-agent runtime scalability
These primitives lay the technical foundation for a global AI agent economy — one where KOLI’s digital twins and intelligent agents interact, transact, and evolve in an open, secure, and incentive-aligned Web3 environment.
