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.

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 automatically

Advantages:

• 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:

Registry Type	Function
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

4. AgentPool Module

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.
