What is this?

An interactive visualization of ERC-8004: Trustless Agents, the emerging Ethereum Improvement Proposal that enables AI agents to discover, trust, and interact across organizational boundaries without pre-existing relationships.

🔥 Why ERC-8004 Matters

As AI agents become autonomous and widespread, a critical challenge emerges: How can agents from different organizations trust each other?

ERC-8004 solves this by:

• ✅ Agent Discovery - Find agents across organizational boundaries
• ✅ Reputation System - On-chain attestations for trust validation
• ✅ A2A Protocol - Agent-to-Agent communication standards
• ✅ No Pre-existing Trust Required - Trust is built from on-chain data

🎯 Key Features

• Interactive Agent Network - Click agents to view details and connect
• Real-time Trust Scores - Dynamic reputation visualization with color-coded indicators
• Agent Discovery Simulation - See how ERC-8004 enables agent discovery
• Status Tracking - Monitor agent states (active, verifying, idle)
• Skill & Capability Display - View what each agent can do
• Activity Log - Track interactions and discovery events

🛠 Tech Stack

• Next.js 15 - React framework with App Router
• TypeScript - Type-safe development
• Tailwind CSS - Utility-first styling
• Lucide React - Beautiful icon set
• Vercel - Deployment platform

🎨 How to Use

1. Explore the Agent Network - Browse available agents from different organizations
2. Click Any Agent - View detailed information, trust scores, and capabilities
3. Start Agent Discovery - Click the button to simulate ERC-8004 agent discovery process
4. Watch Activity - Monitor the activity log for real-time events

📊 ERC-8004 Overview

What is ERC-8004?

ERC-8004 extends the Agent-to-Agent (A2A) protocol with a trust layer that allows participants to:

• Discover agents across organizational boundaries
• Choose agents based on reputation and capabilities
• Interact with agents without pre-existing trust
• Validate trust through on-chain attestations

How It Works

┌─────────────┐      Discovery      ┌─────────────┐

Key Benefits

Feature	Without ERC-8004	With ERC-8004
Agent Discovery	Manual, fragmented	Standardized, discoverable
Trust Establishment	Pre-existing relationships	On-chain attestations
Cross-Org Interaction	Difficult, risky	Safe, revocable
Reputation	Opaque, centralized	Transparent, on-chain
