🏗️ Project Architecture & Development Process

🔧 Core Architecture

FaceBuddy is a modular AI-powered agent designed for identity verification, payments, and social connectivity on-chain. It integrates multiple Web3 technologies for scalability, decentralization, and seamless user experience.

• User Onboarding & Identity Verification 🆔

  • Face scanning & biometric verification via Humanity Protocol.
  • Self-custodial wallet creation using Coinbase Smart Wallet.
  • Decentralized credential issuance for Telegram, LinkedIn, & more.

• Payments & Token Swaps 💸

  • Auto-swaps tokens using Uniswap v4 on Unichain.
  • Gasless transactions powered by Base’s Paymaster.
  • Seamless payments even for unbanked users.

• Data Storage & Scalability 📦

  • Identity & interaction logs stored with EthStorage & Walrus.
  • Agent execution scaled using EigenLayer AVS.

🚀 Development Process

1. Prototyping & Research 🔍 – Defined problem scope, blockchain integrations, and AI agent capabilities.
2. Smart Wallet & Credential System 🏗️ – Integrated Coinbase Smart Wallet and Humanity Protocol for seamless onboarding.
3. AI Agent Development 🤖 – Built a verifiable agent using Opacity Adapter for automated transactions and connections.
4. Storage & Scalability Enhancements 🔄 – Implemented EthStorage & Walrus for efficient data handling.
5. Testing & Optimization 🛠️ – Ensured error-free execution, fallback mechanisms, and robust scaling.

FaceBuddy is designed to seamlessly verify identities, process transactions, and connect users at scale, making Web3 more inclusive, accessible, and user-friendly. 🌍✨

🌟 Key Differentiators & Uniqueness

🚀 What Makes FaceBuddy Unique?

1. AI-Powered Onchain Identity & Payments 🤖💸

   • FaceBuddy verifies identities, connects users, and facilitates payments seamlessly—all powered by AI.
   • Most identity solutions focus on either verification or payments; FaceBuddy combines both.

2. Gasless, Auto-Swapped Payments 🔄⚡

   • Uses Uniswap v4 on Unichain to auto-swap tokens before sending, ensuring users receive their preferred currency.
   • Eliminates gas fees via Base’s Paymaster, removing a major Web3 adoption barrier.

3. Decentralized, Scalable Data Handling 📦

   • Stores facial hash data, social verifications, and transactions securely using EthStorage & Walrus.
   • Scales agent execution efficiently with EigenLayer AVS—unlike centralized alternatives.

4. Verifiable Credentials & Human Authentication 🆔✅

   • Issues onchain social credentials (LinkedIn, Telegram, etc.) via Humanity Protocol, ensuring trust in digital identities.
   • Unlike Sybil-prone networks, FaceBuddy verifies real human presence through biometric scanning.

🔍 Comparison to Similar Solutions

⚖️ Trade-offs & Shortcuts While Building

⏳ Development Trade-offs & Quick Fixes

1. Faster Onboarding Over Full Decentralization 🏗️

   • FaceBuddy currently relies on Coinbase Smart Wallet for an easy self-custodial setup, but future updates will explore fully decentralized wallet solutions.

2. Limited Payment Methods at Launch 💳

   • Right now, FaceBuddy supports crypto payments via Uniswap v4 auto-swaps, but we aim to expand to fiat onramps for smoother adoption.

3. Optimized for Scale, Not Perfection 🚀

   • We prioritized scalability and fast agent execution using EigenLayer AVS, but there’s room for optimizing transaction efficiency and reducing computational costs.

🔮 Future Optimizations & Enhancements

1. Face-Pay: Pay with Your Face! 🆔💸

   • Inspired by WeChat Pay in China, where 500M+ users pay using facial recognition, FaceBuddy will enable face-based payments linked to verifiable credentials.
   • This would allow seamless crypto and fiat transactions, where users authenticate payments just by scanning their face.

2. Decentralized Identity Evolution 🏛️

   • We plan to expand Humanity Protocol integrations to issue more types of verifiable credentials, enhancing trust & compliance.

3. Multi-Chain Expansion 🌍

   • While FaceBuddy is currently optimized for Base, Unichain, and EigenLayer, we’re exploring cross-chain interoperability to expand accessibility and liquidity.
