🧩 Overview

Zeyo is a privacy-preserving on-chain reputation protocol built on the U2U Network.
It issues Soulbound Tokens (SBTs) as verifiable badges representing users’ DeFi, staking, and ecosystem participation — all without compromising privacy or revealing wallet data.

By leveraging Zero-Knowledge Proofs (ZKPs) and U2U’s DAG-based infrastructure, Zeyo enables users to prove their on-chain achievements (staking, bridging, lending, governance, etc.) in a trustless, privacy-first manner.
Each verified activity is represented by a non-transferable SBT, serving as a proof of contribution within the U2U ecosystem.

Zeyo transforms reputation into an on-chain credential layer — empowering users to build identity and trust without KYC, doxxing, or surveillance.

❌ Problem

Traditional blockchain reputation systems rely on public wallet analysis, exposing sensitive data and creating permanent, traceable histories.
This lack of privacy discourages participation and limits composability across DeFi and governance ecosystems.

There’s a clear need for a privacy-preserving, verifiable reputation standard that validates user participation without sacrificing anonymity.

✅ Solution

Zeyo introduces a Zero-Knowledge reputation framework on the U2U Network, powered by:

• 🔒 ZK Proofs (Circom/SnarkJS) for privacy-preserving verification

• 🪙 ERC-1155 Soulbound Tokens (SBTs) to represent user achievements

• 🤖 AI Agent Integration for activity validation using the U2U API

Users connect their wallet, validate activity (staking, lending, governance), and Zeyo mints a verifiable SBT backed by ZK validation — proving participation without revealing any private details.

🌍 Impact

Zeyo strengthens U2U’s ecosystem by:

• Enabling trustless and private reputation systems for DeFi, GameFi, and SocialFi

• Expanding network utility with verifiable, privacy-first participation

• Fostering a user-centric, compliance-ready identity layer for Web3 scalability

• Accelerating U2U adoption through composable on-chain credentials

By combining privacy, verifiability, and interoperability, Zeyo lays the foundation for a self-sovereign reputation layer within the U2U ecosystem.

⚙️ Core Features

1. Privacy-Preserving Verification

Zero-Knowledge Proofs ensure users can verify participation without exposing wallet or transaction data.

2. Soulbound Identity Layer

ERC-1155-based SBTs represent user achievements — immutable, non-transferable, and publicly verifiable on U2U.

3. AI-Driven Activity Validation

An AI agent validates user actions (staking, lending, governance) via the U2U API before proof generation.

4. On-Chain Reputation Dashboard

Users can view all badges and achievements on the Zeyo dashboard, creating a transparent yet privacy-respecting on-chain identity.

5. Seamless Integration

Compatible with DeFi protocols, DAO tools, and GameFi systems across the U2U Network.
Can serve as a composable credentialing layer for ecosystem-wide adoption.

💠 Why U2U Network

U2U’s DAG + EVM hybrid architecture offers ultra-fast finality, high throughput, and low transaction fees — critical for privacy computation and real-time proof validation.

By deploying on U2U:

• ZK verification executes efficiently at scale

• SBT minting remains low-cost and energy-efficient

• DApps can leverage Zeyo credentials across DeFi, SocialFi, or RWA use cases

This makes U2U the ideal network for privacy-preserving, credential-based protocols like Zeyo.

🧱 Technical Stack

🔄 How It Works

Phase 01 – Connect & Validate

1. Users connect their wallet using MetaMask or Reown

2. They select an activity such as staking, lending, or governance participation

3. Zeyo’s AI agent verifies activity through the U2U API

Phase 02 – Generate & Mint

1. Upon successful verification, a Zero-Knowledge Proof is generated

2. A Soulbound Token (SBT) is minted representing the verified achievement

3. This badge becomes a privacy-preserving proof of participation across the U2U ecosystem
